Frequently Asked Questions - S-WKCM8000-115-2 WhisperKOOL

How do I set the temperature on my WhisperKOOL S-WKCM8000-115-2?

Press the SET button until 'SEt' appears, then press SET again. Use the UP/DOWN arrows to adjust between 50°F and 70°F. Press ESC to confirm. The display must be unlocked by holding any button for 1 second first.

What does alarm code E1 mean?

E1 indicates the bottle probe is not connected or faulty. Check the probe connection at the circular connector and ensure it is securely plugged into the CPB/PB1 terminal on the circuit board. If the probe is defective, replace it.

How often should I clean the coils?

Clean the evaporator and condenser coils monthly using a vacuum with a brush attachment. Be careful not to damage the fins. Quarterly, a deeper cleaning with a mild detergent may be needed.

What is the pump down cycle?

The pump down cycle stores most refrigerant in the condensing unit and receiver when cooling stops. A solenoid valve closes, stopping liquid flow, and the compressor runs until suction pressure drops, then the low-pressure switch shuts it off. This eliminates the need for wiring between units.

Can I install this unit myself?

No. WhisperKOOL requires installation by a certified HVAC-R technician (NATE or equivalent). Improper installation voids the warranty and can cause damage. The unit must be brazed, evacuated, and charged properly.

What is the bottle probe for?

The bottle probe measures liquid temperature (simulating wine) rather than air temperature. Place it in a 75% full water bottle in the cellar. This allows the system to run 75-80% of the time, maintaining more stable humidity and temperature.

How do I adjust the TXV?

Remove the cap from the TXV superheat adjustment port with a 5/32" hex key. Turn clockwise to increase superheat, counterclockwise to decrease. Aim for a superheat of 20-30°F at the suction line service valve.

What is covered under the 2-year warranty?

WhisperKOOL covers parts and labor for defects in material and workmanship for 2 years. Labor reimbursement up to $250. Freight for replacement parts if defect is manufacturer’s fault. Does not cover installation errors, improper voltage, or misuse.

How should I route the drain line?

Use 1/4" ID clear tubing (not provided). Connect to the barbed coupling on the condensate pump. Route to a proper discharge location, ensuring a downward slope and that the line end is above the water level to prevent mold. Maximum vertical lift is 15 ft.

What is the anti-frost cycle?

When the evaporator probe senses 26°F for one minute, the compressor shuts off and the fan runs to melt frost. 'dEF' displays. The compressor restarts when the coil reaches 40°F or after one hour. This prevents ice buildup on the coil.

WARNING

The evaporator unit (fan coil unit) must be insulated using the insulation blanket provided in accordance with this manual. Refer to the insulation blanket installation instructions.

Failure to follow the instructions provided will result in a poor vapor barrier, water damage, rust, and system corrosion which will void the warranty on your unit.

The evaporator unit (fan coil unit) must be insulated using fiberglass insulation (R19 or higher) in addition to the provided insulation blanket. This includes the cavity between the ceiling joists. A warm attic environment will reduce the capacity of the cooling system, as the system will absorb heat from the attic in addition to the heat load from the wine cellar. This, in effect, will significantly reduce the cooling system's ability to cool the wine cellar.

Failure to properly insulate the evaporator unit may cause condensation to form on the surface of the housing and water damage to the surrounding structure, the cooling unit, and possibly the wine cellar.

To avoid these issues, install the insulation kit and insulate the surface of the evaporator unit that is located outside of the wine cellar using fiberglass insulation.

*Additional insulation is required!

Please read and review this manual carefully and keep it for future reference.

What is the WhisperKOOL Cooling System?

The WhisperKOOL cooling system is a specialized refrigeration system designed for one purpose only: to maintain the optimal temperature and humidity levels conducive to the proper storage and aging of fine wines. This system produces minimal in-cellar noise and has the most lenient exhaust requirements. An exterior housing is required for outdoor condensing unit installations.

How Does the Cooling System Work?

Similar to the air conditioning systems used for homes, the evaporator unit and condensing units are installed in separate locations and are connected by a refrigerant line set. The evaporator portion is commonly installed in the wine cellar, with the condensing unit is located either outside or in a remote indoor location that is ventilated. An exterior housing is required for outdoor condensing unit installations.

Temperature Setting

The system is designed to maintain a cellar temperature of 55° F as long as the ambient temperature does not exceed 110° F.

WARRANTY REGISTRATION

QUICK START GUIDE*

Pump Down Cycle

WhisperKOOL's split systems operate on a pump down cycle different from traditional air conditioners. As such, there is no wiring between the condensing unit and evaporator unit.

WhisperKOOL units utilize a solenoid valve on the liquid line and a low-pressure switch on the suction line. When the thermostat calls for cooling, the solenoid valve opens, permitting the flow of refrigerant. The low-pressure switch then signals the compressor to cycle on.

When the cellar reaches the desired temperature and the thermostat is satisfied, the solenoid will close, stopping the liquid refrigerant flow to the TXV valve. The compressor will continue to operate until most of the refrigerant on the low side boils off and is pumped through the compressor into the condenser coil and receiver. As the suction pressure falls below the pressure control setting, the low-pressure switch will signal the compressor to cycle off. Most of the refrigerant is now stored between the condensing unit and receiver.

WARNING: Do not utilize a ground fault interrupter, as it will prevent the unit from drawing the necessary amperage to start the unit.

TXV Adjustments

A. A TXV adjustment may be necessary based on ambient temperatures in the cellar and at the condensing unit.
B. Adjust the TXV until the total superheat measured at the suction line valve is 20-30°F.
C. Under normal operation, with the wine cellar at 55° F and the ambient temperature at 85° F, the low side pressure should be between 28-32 PSI and the high side should be between 145-155 PSI.

TXV

The TXV is preadjusted at the factory. If the superheat is not within 20-30° at the service valve, the TXV will need to be adjusted.

ADJUSTING THE TXV

Use a 5/32 " hex key to remove the cap from the TXV superheat adjustment port. With the cap removed, insert the hex key into the superheat adjustment port. Increase superheat by turning the hex key clockwise. Decrease superheat by turning the hex key counterclockwise.

Liquid Line King Valve

This location is used to charge the system with liquid refrigerant and identify the high side pressure of the system.

Calculating Subcooling

To determine the subcooling of the system, calculate the difference between the high side pressure of the system (converted to

temperature) and the temperature of the liquid line. The temperature of the liquid line will be taken at the outlet of the receiver.

*Saturation temp — liquid line temp

4-6°F SUBCOOLING REQUIRED FOR WARRANTY APPROVAL

*Further system operation information is available on page 40.

* Sizing the Unit to the Room

The specification chart will provide information on the unit's cooling capacity. There are circumstances in which a cellar design may require a larger unit due to preexisting design restrictions. Certain building materials such as glass, stone, or concrete may seem adequate but do not offer the insulation capacity required to maintain the optimum temperature for storing wine. We recommend purchasing a unit with a larger capacity to compensate for these design limitations. Undersized cooling units can lead to premature failure and/or prevent the system from reaching the desired set temperature. As a result, they are not covered under warranty.

1. Wrap insulation piece (A) around the sides of the evaporator unit. Make sure the bottom edge of the insulation is flush with the top edge of the mounting bracket (see illustration).

If needed, trim excess insulation around all edges.

1. Set insulation in place by pressing firmly on all surfaces of the insulation that come in contact with the sides of the evaporator unit (see illustration).
2. Using a utility knife, cut holes in the insulation for the line set, wiring, and drain line if needed.
3. If necessary, cut the insulation to size using the top edge of the evaporator unit as a template. Remove excess insulation. Proceed to piece (B) installation.

INSULATION BLANKET INSTALLATION, CONTINUED

1. Spray the top of the evaporator unit with spray adhesive. (See spray adhesive directions for proper tack time before proceeding to step 8.)

1. Set piece (B) in place by pressing firmly on all surfaces of the insulation that come in contact with the top of the evaporator unit (see illustration).

1. Using a utility knife, cut holes in the insulation for line set, wiring, and drain line if needed.

If needed, trim excess insulation around all edges.

1. Once insulation is installed, apply foil tape to all seams, covering them completely.
2. Inspect insulation for damage/defects. If damaged, repair with foil tape.
3. Apply cork tape or equivalent to areas where the line set, wiring, and drain line enter the unit.

DRAIN LINE

Condensation Drain Line

The condensation drain line tube is used to remove excess condensation from the unit to a proper discharge location. It is important that the drain line tube is properly connected.

Failure to use the condensation drain line tube will void the warranty on the unit.

Drain Line

The Ceiling Mount evaporator unit features a drain line pump system that removes excessive condensate build up in the drain pan. During operation, the drain pan collects water that drips from the coil. The drain line pump system will prevent overflow and leaking by allowing for discharge of the additional condensate.

Connecting the Drain Line

Route the drain line to an appropriate discharge location and connect the opposite end to the tubing that was routed out with the line set using the provided barbed coupler side of the condensate pump. Do not route the drain line more than 15 vertical ft.

WRONG: Drain line is under water.
To prevent mold from growing, allow the drain line to hang above the water line.

LIQUID-MEASURING THERMOSTAT SYSTEM (BOTTLE PROBE)

WhisperKOOL cooling units come with a liquid-temperature-measuring thermostat. The self-calibrating probe contains a sensor chip, which communicates back and forth with the thermostat. This results in a consistent temperature setting and accuracy. Wine should be kept at a very precise, controlled temperature and humidity. By measuring the liquid temperature rather than air, the unit will operate 75–80% of the time.

Setting up the Bottle Probe:

1. Locate an empty wine bottle.
2. Fill it 75% full with room-temperature tap water.
3. Place bottle probe securely into bottle as seen in Figure 1.
4. Place the wine bottle in your wine cellar. Ensure sensor tip is fully submerged.
5. To ensure a consistent temperature, place bottle probe approximately three (3) feet away from the air output and not in the flow of the air.

It is recommended that the bottle be placed in a central location of your wine cellar. Avoid pulling too much on the probe cord. It may become disconnected resulting in limited functionality of the unit.

Note: The thermostat can be set between 50–70°F.

Remember: The unit operates based on the temperature of the water.

Do not be misled by thermostats reading air temperature. The air temperature in the cellar will be cooler than the liquid temperature of the wine while it is reaching the optimum balanced temperature.

REMOTE DISPLAY: INSTALLATION AND CONFIGURATION*

PREPARING THE CONDENSING UNIT

Electrical Needs

The 4000 condensing unit requires a dedicated 115V, 15-amp circuit.

The 8000 condensing unit requires a dedicated 115V, 20-amp circuit.

The unit draws a large inrush current for about 1 second the instant the compressor starts. With a dedicated circuit and circuit breaker, the condensing unit will have sufficient power for effective operation. (The compressor is controlled by a low-pressure transducer mounted on the condensing unit. This feature eliminates the need for wiring between the evaporator unit/fan coil unit and the condensing unit.)

• Ensure the voltage supplied matches the rating specified on the unit spec label.
• Provide a non-GFI dedicated circuit and an appropriate outlet for the evaporator unit.
• Provide a dedicated circuit and circuit breaker for the condensing unit.
• Provide a weatherproof disconnect for the condensing unit if it is located outside.

Power surges and spikes can damage sensitive electrical equipment. WhisperKOOL recommends plugging the unit into a surge protector or power conditioner in order to protect your system. As outlined in our terms and conditions, power surges and spikes are not covered under warranty.

WE RECOMMEND THAT YOU DO NOT USE A GROUND FAULT INTERRUPTER (GFI) WITH THIS PRODUCT.

In case the system should lose power, check the home/main circuit breaker. If the system does not respond properly, refer to the Troubleshooting Guide on page 48.

PREPARING THE CONDENSING UNIT (continued)

The condensing unit can be installed inside a well-ventilated area of the home, but is typically installed outside. Exterior applications will require the use of a protective housing. The amount of sun exposure should be considered when selecting the placement of the condensing unit. The 4000 condensing unit requires a dedicated 15-amp circuit (non-GFI). The 8000 condensing unit requires a dedicated 20-amp circuit (non-GFI). Make sure there is a minimum of three (3) feet of horizontal clearance in every direction around the unit (five feet is ideal). The unit may either be hard-wired or plug-in, depending on local electrical codes.

Indoor condensing unit installations: Inside installations require special consideration, as there must be adequate ventilation to remove the heat created during normal operations. An exhaust port with fan may need to be installed to ensure that heat is effectively removed from the utility room. There must be a return grille or provision for 500-600 CFM of cool air to enter the room to replace the exhausted air. Unobstructed airflow to and from the unit is a critical factor in the unit's overall performance. Make sure there is a minimum of three (3) feet of horizontal clearance in every direction around the unit (five feet is ideal). This will assure that the unit can move the air around the room in an efficient manner.

Outdoor condensing unit installations: You must utilize the exterior condensing unit housing for outdoor installations. Place the condensing unit on a solid foundation in a location with adequate ventilation. Make sure there is a minimum of three (3) feet of horizontal clearance in every direction around the unit (five feet is ideal). The unit should be elevated 18 inches in order to avoid any possible flooding or damage by animals, and should be clear of leaves, dirt, and other debris.

INSTALLING THE CONDENSING UNIT

DO NOT BLOCK airflow through the exterior housing. This will restrict airflow and void the warranty.

Refrigerant Piping Overview

• Using the charts and illustrations found above, route the line set between the evaporator unit and condensing unit. Be sure to reference the chart for correct line set sizing. All horizontal suction piping should be pitched toward the condensing unit half an inch for every 10 feet of pipe. When installing and routing the line set, cap both ends of each tube to prevent debris from entering the tubing.

• Prior to connecting the piping to the evaporator and condensing units, loosely connect a refrigerant manifold to the suction and liquid line service valves.

• Purge the hoses with dry nitrogen and tighten the hose connections.

• Remove the service valve caps and turn the valve stem clockwise half a turn to unseat the valve and open the service port. Keep the piping ports sealed until ready to braze.

• Purge the fittings with dry nitrogen at a slow rate to prevent formation of highly abrasive copper oxide.

• Perform all brazes.
  • Pressure test the system and check for leaks.
• Insulate the suction line using wall cellular insulation or equivalent. Seal all seams with Armaflex 520 foam insulation adhesive or equivalent. Wrap each seam using line set tape.

Liquid Line Piping Procedure

• Refer to the line set piping chart for liquid line size requirements.
- Braze a short piece of copper tubing to the liquid line service valve.
- Connect the supplied refrigerant drier to the tubing.
- Downstream from the drier, connect the moisture-indicating sight glass in an easily visible location.
- Run the tubing to the evaporator unit and attach to the liquid line connection on the evaporator unit.

Suction Piping Procedure

• Connect an appropriately sized suction line to the suction line service valve on the condensing unit.
• Run the pre-insulated suction line to the evaporator unit and attach to the suction line connection on the evaporator unit.

Brazing Procedure

• Connect the bottle probe to the evaporator unit.
• Fill a wine bottle 75% full of room-temperature water. Insert the bottle probe into the neck of the bottle as far as possible. It is important that the bottle probe stopper be compressed by the neck of the bottle to ensure water will not leak.
• Energize the evaporator unit and set the controller to call for cooling.
• Verify that the setpoint on the control is set low enough to allow the unit to run for the entire length of the brazing, evacuation, and charging procedure.
• Remove the valve depressors from the gauge hoses on a four-valve manifold.
• Connect the manifold to the low-pressure service valve port on the condensing unit and a nitrogen tank.
• Open the suction line service valve and purge the system with nitrogen.
• Braze all connections and cool off quickly.
• Connect the high-pressure hose from the manifold to the liquid line service valve port.
  • Pressure test the system at 150 psi for 20 minutes.
• Check all braze joints with leak detector or soap bubbles.
• Release the nitrogen once it is confirmed that there are no leaks.

INSTALLING THE CONDENSING UNIT (continued)

Evacuation

- Remove the nitrogen tank from the manifold and attach the manifold to the refrigerant tank.

• Mid-seat both service valves.

• Install service caps on the valves.

• Energize the liquid line solenoid valve.

• After confirming that there is fresh oil in the vacuum pump, connect the 3/8 " hose from the manifold to the pump.

- Start the pump and run it until the micron gauge on the evaporator unit reads 500 microns or less.

- Disconnect the vacuum pump from the system.

- Break the vacuum by pressurizing the system to approximately 5 PSI with R-134a refrigerant.

- Remove the micron gauge from the access valve.

Charging

- With the power off to the condensing unit, admit liquid refrigerant through the liquid line service valve until the refrigerant stops flowing.

- Turn on the circuit breaker for the condensing unit. The compressor should turn on if the pressure in the suction line is above 20 psi.

- Add refrigerant (in vapor form) to the low side of the system through the suction line service port.

- Observe the sight glass. If bubbles are present, add more refrigerant (in vapor form) to the low side.

- Once the sight glass is clear, check the superheat at the outlet of the evaporator unit. Adjust the TXV until the superheat is between 20-30°F degrees.

• Under normal operation, with the wine cellar at 55° F and the ambient temperature at 85° F, the low side pressure should be between 28-32 PSI and the high side should be between 145-155 PSI.

Finalizing the Installation

- Confirm that the entire suction line from the TXV to the suction line service valve is insulated using cellular insulation or equivalent. Seal all seams with Armaflex 520 foam insulation adhesive or equivalent.

- Confirm that the control is displaying the correct temperature and that no alarms are present. Refer to page 44 for corrective action if alarms are present.

FINALIZING THE INSTALLATION

1. Push the grille back into place. This will attach the grille to the ball studs.

2. Screw in the eight screws to secure the front access panel.

SYSTEM OPERATION

Initial Start-Up

When the unit is plugged in and power is sent to the controller, a beep will sound, confirming that the controller is getting power. All LEDs on the display will blink three times. Three dashes will then appear on the screen. All display LEDs will then blink three times. Once the controller has gone through the initial startup process, and all LEDs have cycled, the home screen will be displayed.

Setpoint

The setpoint is preset at the factory to 55°F. It can be adjusted by the customer between 50–70°F in one-degree increments.

Indoor Fan Operation

The indoor fan will run when the controller is calling for cooling and turn off once the cooling cycle has ended. During the cooling cycle, the system will remove some relative humidity from the cellar. Some of the humidity that was removed can be reintroduced into the cellar by adjusting the "fan on" and "fan off" functions. (The cooling system is not equipped with a humidifier and does not add humidity.)

The FOF cycle should be shortened first. This will reduce the amount of time that the fan remains off following a cooling cycle. When the unit has completed a cooling cycle, the compressor and the condenser fan will turn off, but the indoor fan will continue to run for whatever length of time the customer has set. The Fon function may then be lengthened to allow the fan to run longer and reintroduce moisture from the evaporator coil back into the wine cellar.

For more information about fan settings, refer to the User Menu on page 45.

Anti-Short Cycle

The Anti-Short Cycle ensures that the unit will remain off for a period of five minutes after the unit has reached the setpoint. This allows the pressure in the refrigeration system to equalize prior to starting the compressor.

Once the solenoid relay is de-energized, the controller must wait five minutes before reenergizing the relay. This prevents the compressor from repeatedly turning off and on. If the unit is calling for cooling during this time, the compressor icon will blink, indicating that cooling is needed but the controller is waiting for the Anti-Short Cycle delay.

Anti-Frost Cycle

When the evaporator probe senses a temperature of 26° F for a duration of one minute, an Anti-Frost Cycle will be initiated. This will shut down the compressor, allowing the evaporator fan to run and melt any frost accumulation on the coil. While the Anti-Frost Cycle is running, "dEF" will be displayed on the screen. The compressor will remain off until the evaporator coil reaches 40° F, or for a maximum of one hour. The unit will then return to normal operation.

Operation in Low Ambient Temperatures

The condensing unit comes equipped with a LAC (Low Ambient Control). The LAC is a three-way modulating valve that responds to discharge pressure. When the discharge pressure falls below the valve's dome pressure, the valve modulates open to the discharge port which allows discharge gas to bypass the condenser. Mixing the discharge gas with the liquid creates high pressure at the condenser outlet, reducing the flow and causing liquid to backup in the condenser. Flooding the condenser reduces the area available for condensing. This reduction in condenser surface area results in a rise in condensing pressure during cold ambient conditions.

The condensing unit controller comes preset from the factory with the cut-in pressure at 25psi and the cut-out pressure at 15psi. During low ambient temperatures (40°F or below), it will be necessary to adjust the cut-in pressure to 10-15psi (15psi preferred) and the cut-out to 5psi to ensure compressor startup. See page 46 for instructions on adjusting the cut-in and cut-out pressures of the condensing unit.

Digital Display

The display is designed to give the user the ability to adjust the setpoint, Fon/FOF parameters, and other settings. (See User Menu on page 45 for more details.) The bottle probe temperature is displayed by default. "dEF" will be displayed during an Anti-Frost Cycle. The bottle probe and evaporator probe temperatures can be accessed by pushing the SET button and scrolling through "Pb1" (bottle probe) and "Pb2" (evaporator probe). The light button may be used as an unlock button.

Safety Features

In the event of a faulty bottle probe, the compressor will cycle off for 10 minutes and on for 40 minutes. "E1" will be displayed on the screen.

The evaporator unit comes equipped with a condensate pump to remove the condensation produced by the evaporator coil. The reservoir is mounted in the internal drip tray and will kill power to the unit if the condensate level rises too high.

If the drain line is obstructed or the pump fails for some reason, and the water level in the drip tray gets too high, the unit will not operate until the water in the internal drip tray drops back below the proper level.

In this event the controller will send an alarm to the display. (The alarm message, EA, can be viewed in the User Menu's ALr folder.)

USER MENU

The User Menu is accessed by pressing and holding the SET button for 3 seconds. Use the UP and DOWN ARROW buttons to navigate to desired parameters. Press the SET button again to view these parameters. Press the UP and DOWN ARROW buttons to adjust a parameter.

The following parameters are available in the menu:

Parameter Description
Fdc - humidity enhancement This parameter	is measured in minutes, and is preset at the factory to 1. An increase in this parameter will increase the humidity enhancement of your cellar. This parameter should not be adjusted to zero. Adjustments should be made in increments of 5, with a maximum of 15 and a minimum of 1. After making any adjustments to humidity enhancement,you should wait a minimum of 3 days before making any additional adjustments. This will allow sufficient time for the cellar to acclimate to the new setting.
FOF - “fan off” This setting controls how long	the fan stays off after the setpoint has been reached. It is preset to 15 minutes. This setting should not be adjusted, as most properly constructed wine cellars retain an ample amount of humidity during the “fan off” cycle. If, however, you wish to decrease the duration of the “fan off” cycle (in order to increase the wine cellar’s relative humidity), you can adjust this setting in the User Menu.
Fon - “fan on” The “fan on” time is preset to	zero minutes. This keeps the relative humidity of the wine cellar at a stable level. If, however, you wish to raise the relative humidity of your wine cellar, you can increase the duration of the “fan on” cycle in increments of five (5, 10, or 15 minutes). After making any adjustment to the “fan on” cycle,you should wait a minimum of 3 days before making any additional adjustments. This will allow sufficient time for the cellar to acclimate to the new setting.
CA1 - bottle probe (Pb1) calibration	CA1 - bottle probe (Pb1) calibration:You may use this parameter to calibrate the bottle probe to a known temperature. This parameter can be adjusted between -12°F and 12°F. For example, if the bottle probe temperature is 58°F, and the known temperature is 55°F, you can set the CA1 parameter to -3°F to match the known temperature.
PA2 - installer menu This menu is only accessible using a password and is not available for adjustment.
dOA - digital input This setting determines	which of the unit’s components will be activated or deactivated when a certain electrical relay is activated or deactivated in response to an alarm. The controller comes pre-programmed with a factory setting of 2.2 = activates the compressor and fans5 = disables the compressor and fansNOTE:Setting the dOA to any number other than 2 or 5 will prevent the unit from operating properly.

Care and Cleaning of Air Cooled Condensing Units

Introduction

Proper care is essential to assure good life of condensing units. Dirty or damaged condensers will reduce the efficiency and capacity of the system.

Care must be taken in choosing solutions to be used for cleaning condensers and condensate pans. Chlorinated cleaners and anti-bacterial cleaning agents can be damaging and should be avoided. Caustic and acidic cleaners should be avoided as well. Failure to do so may accelerate component corrosion and ultimately lead to component failure.

Condenser Coils

There are many commercially available condenser coil cleaners on the market. Coil cleaners should be designed to remove build-up on fins and coils. Coils should be thoroughly rinsed of the cleaners once cleaning has been completed. Follow the manufactures instruction for proper usage. Preventive maintenance and routine cleaning of coils is important to assure good life.

When cleaning the coil, an absorbent type material should be placed under the area to be cleaned in order to capture most of the cleaning compound, thus minimizing any type of chemical attack.

Condensate Pans

Condensing units with condensate pans and condensate tubes are designed to evaporate condensate water only. Other ingredients introduced into the condensate pan can accelerate pan and/or tube corrosion. As foreign agents are introduced into the condensate pan, condensate water will be evaporated leaving the foreign agent behind. This can lead to a high concentration of the agent and possible corrosion of the tubing and/or base.

Coil cleaning agents must not be allowed to drain into the condensate pan as this may cause damage. Upon completing the coil cleaning, be certain that all residue is removed from the condensate pan.

Only non corrosive cleaners should be used to assure good life of the condensing unit components. No hydrocarbon based cleaners should be used to clean the unit. Bleach solutions must be avoided due to its high corrosive nature.

Under no circumstances should cleaning agent ingredients contain any of the solutions listed below:

Unacceptable solutions are:

Chlorinated Solvents

Bleaches

Vinegar

Ammonia

Anti-Bacterials

Salts

Preventative Maintenance

Maintenance should be performed at regular intervals. Coils should be cleaned at least monthly, possibly more depending on the environment. Condensing units with condensate pans should also be checked and cleaned regularly to prevent damaging build up in the pan.

Safety

Please follow all safety recommendations listed by the manufacturer of the cleaning agent(s), these would include proper clothing, gloves and eye protection.

BYPASS TEST PROCEDURE

NOTE: If instructed by a WhisperKOOL representative, follow the directions below to test the cooling unit using the bypass plug provided in the accessory kit.

1. Disconnect power from the evaporator unit.
2. Loosen the two (2) screws on the front of the grille or duct plenum.
3. Pull the grille or duct plenum away from the evaporator unit.
4. Remove the screw securing the control panel in place.
5. Slide the control panel down, out of the evaporator housing. The control panel has two (2) hooks which allow it to attach to the evaporator unit for easy serviceability.
6. Disconnect the Molex connector labeled #4.
7. Locate the bypass plug included in the accessory kit.
8. Plug the bypass plug into the male Molex connector.
9. Connect power to the evaporator unit. The unit should immediately turn on. If all the components are not operational, disconnect power immediately and contact customer service. If all components seem to be operating correctly, allow the unit to run for four (4) hours. Monitor the temperature of the cellar to determine if the unit is cooling properly.
10. Once the test is complete, remove the bypass plug. Plug the Molex connector back in to the unit's wiring.
11. Replace the control and faceplate.

ACCESSORIES FOR COOLING UNITS

WhisperKOOL offers accessories to enhance and customize your wine cooling unit:

Condensate Pump Kit

The condensate pump kit automatically removes water that drips out of the evaporator unit's drain line. The pump is controlled by a float/switch mechanism that turns the pump on when approximately 2½" of water collects in the tank, and automatically switches off when the tank drains to approximately 1¼". The condensate pump kit allows the excess condensate to be pumped up to 20 feet away from the unit.

Exterior Housing

If the cooling unit is installed outside, it will need protection from sun, wind, and rain. The exterior housing protects the condensing unit portion of the split system from the elements when installed outdoors.

Accessories can be purchased at www.whisperkool.com
