Frequently Asked Questions - CR230216G002 Hoffman

How do I install the air conditioner?

Installation should be performed by a qualified technician. Refer to the manual for detailed steps, including mounting the indoor unit, connecting the refrigerant lines, and electrical wiring. Ensure the outdoor unit is placed on a stable surface with proper ventilation.

How often should I clean the filter?

Clean the washable pre-filter every two weeks under normal usage. Remove the filter from the indoor unit, wash it with lukewarm water and mild detergent, let it dry completely, and reinstall. A dirty filter reduces efficiency and may cause ice buildup.

What does the 'Error Code E1' mean?

Error code E1 typically indicates a room temperature sensor fault. Check if the sensor is properly connected. If the problem persists, contact a service technician.

Can I use the air conditioner in winter for heating?

Yes, this model has a heat pump function and can provide heating even in low outdoor temperatures (down to -5°C). However, efficiency may decrease in extreme cold.

How do I set the timer?

Press the TIMER ON button on the remote control to set the turn-on time, or TIMER OFF for turn-off. Use the + or - buttons to adjust hours. Confirm by pressing TIMER again.

Why is the air conditioner not cooling properly?

Possible causes: dirty filter, blocked outdoor unit, low refrigerant, or incorrect mode. First, clean the filter and ensure the outdoor unit has sufficient airflow. If the issue persists, contact a professional.

How do I replace the remote control batteries?

Slide the back cover off the remote control. Insert two AAA batteries with correct polarity (+/-). Replace the cover. Do not mix old and new batteries.

What is the recommended temperature setting?

For optimal comfort and energy savings, set the thermostat between 24-26°C in summer and 20-22°C in winter. Avoid extreme settings to reduce energy consumption.

How can I reduce noise from the outdoor unit?

Ensure the outdoor unit is installed on a vibration-absorbing pad and away from windows or walls that can amplify sound. Regular maintenance, such as cleaning the condenser coils, also helps.

Where can I find spare parts or service?

Contact Hoffman authorized service centers or visit the official website. Common spare parts like filters and remote controls are available online. Use only genuine parts to maintain warranty.

RECEIVING THE AIR CONDITIONER

Inspect the air conditioner. Check for concealed damage that may have occurred during shipment. Look for dents, scratches, loose assemblies, evidence of oil, etc. Damage evident upon receipt should be noted on the freight bill. Damage should be brought to the attention of the delivering carrier -- NOT to Pentair Equipment Protection -- within 15 days of delivery. Save the carton and packing material and request an inspection. Then file a claim with the delivering carrier.

Pentair Equipment Protection cannot accept responsibility for freight damages; however, we will assist you in any way possible.

HANDLING AND TESTING THE AIR CONDITIONER

If the air conditioner has been in a horizontal position, be certain it is placed in an upright, vertical or mounting position for a minimum of five (5) minutes before operating.

CAUTION

Do not attempt to operate the air conditioner while it is horizontal or on its side, back or front. The refrigeration compressor is filled with lubricating oil. This will cause permanent damage to the air conditioner and also voids the warranty.

TEST FOR FUNCTIONALITY BEFORE MOUNTING THE AIR CONDITIONER TO THE ENCLOSURE.

Refer to the nameplate for proper electrical current requirements, and then connect the power cord to a properly grounded power supply. Minimum circuit ampacity should be at least 125% of the amperage shown in the design data section for the appropriate model. No other equipment should be connected to this circuit to prevent overloading.

Operate the air conditioner for five (5) to ten (10) minutes. No excessive noise or vibration should be evident during this run period. The condenser blower (ambient air), the evaporator blower (enclosure air), and the compressor should be running.

Condenser air temperatures should be warmer than normal room temperatures within a few minutes.

The compressor is provided with automatic reset thermal overload protection. This thermo-switch is located and mounted inside the plastic enclosure clipped to the compressor. The switch operates when the compressor overheats due to clogged or dirty inlet air filter or if ambient air temperatures exceed nameplate rating or if enclosure dissipated heat loads exceed the rated capacity of the air conditioner. The thermal overload switch will actuate and stop compressor operation. The blowers will continue to operate and the compressor will restart after it has cooled to within the thermal overload cut-in temperature setting.

INSTALLATION INSTRUCTIONS

1. Inspect air conditioner and verify functionality before mounting the air conditioner, see HANDLING AND TESTING THE AIR CONDITIONER on page 3.
2. Using the cutout dimensions shown in this manual, prepare the air "IN" and air "OUT" openings, and mounting bolt hole pattern for the enclosure.
3. Using the gasket kit provided, install gaskets to air conditioner. See Mounting Gasket Kit on page 6 for proper location.
4. Mount air conditioner on enclosure using mounting bolts and washers provided to secure unit to enclosure. Allow unit to remain upright for a minimum of five (5) minutes before starting. Caution! Air conditioner must be in upright position during operation.
5. Refer to the top of the nameplate for electrical requirements. Connect the power cord to a properly grounded power supply. Use of an extension cord is not recommended. Electrical circuit should be fused with slow blow or HACR circuit breaker.
6. When the unit is equipped with an automatic temperature controller, the controller is preset at the factory for your convenience and should not require adjustment.

SYSTEM CONTROLS

The Level I controller is located inside the air conditioner. To adjust, disconnect power to the air conditioner. Open the front panel by loosening the front panel screw. Refer to Figure 2 on page 7 to locate the controller. Turn the controller adjustment screw slot counter-clockwise to increase and clockwise to decrease the temperature set point, see Figure 1. The thermostat cooling setpoint is indicated by the alignment of the adjustment screw slot with the dial decal. After completing adjustment, close the front panel and tighten the front panel screw. Restore power to the air conditioner for operation.

LEVEL II AND III TEMPERATURE CONTROLLER

The Level II and III controller is mounted on the air conditioner front panel and is factory set for standard operation. All operating parameters are programmable for custom applications. Refer to the Level II and III programming and Operating Instruction Manual, 10-1008-161.

TEMPERATURE CONTROL

The electromechanical thermostat is factory preset to 75 F/23 C. To change the temperature setting, remove the nylon plug from the back face of the unit. Use a standard screwdriver to adjust thermostat. For cooler temperatures turn clockwise, for warmer temperatures turn counterclockwise.

PRINCIPLES OF OPERATION

If electrical power to the air conditioner is interrupted and reapplied immediately (within 3 to 5 seconds), the compressor may not restart due to the high back pressure of the compressor. It takes a minimum of one (1) minute after shut-down for the compressor suction and discharge pressures to equalize in order for the air conditioner to restart.

Operating the air conditioner below the minimum ambient temperature or above the maximum ambient temperatures indicated on the nameplate voids all warranties.

It is recommended that the warranty section of this manual be read in order to familiarize yourself with parameters of restricted operation.

The moisture that the enclosure air can contain is limited. If moisture flows from the drain tube continuously this can only mean that ambient air is entering the enclosure. Be aware that frequent opening of the enclosure's door admits humid air which the air conditioner must then dehumidify.

MAINTENANCE

COMPRESSOR

The compressor requires no maintenance. It is hermetically sealed, properly lubricated at the factory and should provide years of satisfactory operating service.

Should the refrigerant charge be lost, recharging ports (access fittings) on the suction and discharge sides of the compressor are provided for recharging and/or checking suction and discharge pressures.

Under no circumstances should the access fitting covers be loosened, removed or tampered with.

Breaking of seals on compressor access fittings during warranty period will void warranty on hermetic system.

Recharging ports are provided for the ease and convenience of reputable refrigeration repair service personnel for recharging the air conditioner.

INLET AIR FILTER

Proper maintenance of the inlet air filter, located behind the front cover, will assure normal operation of the air conditioner. If filter maintenance is delayed or ignored, the maximum ambient temperatures under which the unit is designed to operate will be decreased.

If the compressor's operating temperature increases above designed conditions due to a dirty or clogged filter (or plugged condenser coil), the air conditioner's compressor will stop operating due to actuation of the thermal overload cut-out switch located on the compressor housing. As soon as the compressor temperature has dropped to within the switch's cut-in setting, the compressor will restart automatically. However the above condition will continue to take place until the filter or coil has been cleaned. It is recommended that power to the air conditioner be interrupted intentionally when abnormally high compressor operating temperature causes automatic shutdown of the unit.

The above described shut-down is symptomatic of a clogged or dirty filter, thus causing a reduction in cooling air flow across the surface of the compressor and condenser coil.

Do not run the air conditioner for extended periods of time with the filter removed. Particles of dust, lint, etc., can plug the fins of the condenser coil which will give the same reaction as a plugged filter. The condenser coil is not visible through the filter opening, so protect it with a filter.

Continued operation under the above conditions can and will damage and shorten compressor life. The air conditioner is available with an easily removable inlet filter to facilitate necessary cleaning. There should be no reason to neglect this necessary maintenance.

HOW TO REMOVE, CLEAN OR INSTALL A NEW INLET AIR FILTER

RP aluminum washable air filters are designed to provide excellent filtering efficiency with a high dust holding capacity and a minimum amount of resistance to air flow. Since they are constructed entirely of aluminum, they are lightweight and easy to service. Optimum filter performance is maintained by recoating the filters after washing with RP Super Filter Coat adhesive. To achieve maximum performance from your air handling equipment, air filters should be cleaned on a regular basis.

The inlet air filter is located behind the right side panel. To access the filter, pull from slot on top cover. The filter may now be cleaned or a new filter installed.

Cleaning Instructions:

1. Flush the filter with warm water from the exhaust side to the intake side. DO NOT USE CAUSTICS.
2. After flushing, allow filter to drain. Placing it with a corner down will assure complete drainage.
3. Recoat the filters with RP Super Filter Coat adhesive. When spraying filter do so from both sides for maximum concentration of adhesive.

CONDENSER AND EVAPORATOR AIR MOVERS

Fan motor requires no maintenance. All bearings, shafts, etc. are lubricated for the life of the motor during manufacturing.

If the condenser fan motor (ambient fan) should fail, it is not necessary to remove the air conditioner from the cabinet or enclosure to replace the fan. The condenser fan is mounted on its own bulkhead and is easily accessible by opening the front cover.

CAUTION

Operation of the air conditioner in areas containing airborne caustics or chemicals can rapidly deteriorate filters, condenser coils, blowers and motors, etc. Contact Pentair Equipment Protection for special recommendations.

REFRIGERANT LOSS

Each air conditioner is thoroughly tested prior to leaving the factory to insure against refrigeration leaks. Shipping damage or microscopic leaks not found with sensitive electronic refrigerant leak detection equipment during manufacture may require repair or recharging of the system. This work should only be performed by qualified professionals, generally available through a local, reputable air conditioning repair or service company.

Refer to the data on the nameplate which specifies the type of refrigerant and the charge size in ounces.

Before recharging, make sure there are no leaks and that the system has been properly evacuated into a deep vacuum.

TROUBLE SHOOTING

BASIC AIR CONDITIONING TROUBLE SHOOTING CHECK LIST

1. Check manufacturer's nameplate located on the unit for correct power supply.
2. Turn on power to the unit. The evaporator (Enclosure or "COLD" air) fan should come on. Is there airflow?

YES, proceed to step 3.

NO, possible problem:

• Open motor winding
• Stuck fan motor
• Obstructed blades

Repair or Replace defective part

1. Check thermostat setting and adjust thermostat to the lowest setting. This should turn on the condenser fan and compressor. Did condenser fan and compressor come on when the thermostat was turned on?

YES, proceed to step 4.

NO, possible problem:

• Defective thermostat

1. Are both fans and the compressor running? If not, the unit will not cool properly.
2. Check condenser (Ambient or "HOT" air) fan for airflow. Is there airflow?

YES, proceed to step 6.

NO, possible problem:

• Defective thermostat
- Open motor winding
- Stuck fan motor
- Obstructed blades

Repair or Replace defective part

1. Carefully check the compressor for operation - motor should cause slight vibration, and the outer case of the compressor should be warm. Is the compressor showing signs of this?

YES, wait 5 minutes, then proceed to step 7.

NO, possible problem:

• Defective thermostat
• Defective capacitor
• Defective overload
- Defective relay

Repair or Replace defective part

1. Make sure the coils are clean. Then check evaporator "air in" and "air out" temperatures. If the temperatures are the same:

• Possible loss of refrigerant
• Possible bad valves in the compressor

Repair or Replace defective part

1. To check for a bad thermostat, turn power off to the unit. Remove control box cover and place both thermostat wires onto one terminal (replace control box cover for safety). This will bypass the switch in the thermostat. Turn on the power. If both fans and the compressor come on, the thermostat needs to be replaced.
