CAUTION

Failure to observe clearance and air flow requirements will result in poor system performance and premature equipment failure!

MISE EN GARDE

Locating and Mounting Evaporator Coil

General Guidelines:

Do not place the evaporator above or close to door openings. This will help prevent potential icing problems.
➢ Allow a minimum clearance equal to or greater than the coil height on all sides of the coil for proper air flow and service access.
Use the evaporator coil for a template to locate and drill the mounting holes (1/2" diameter).
➢ Place a 1" and a 1-5/8" washer on each nylon bolt and insert through the drilled mounting holes in the ceiling from the exterior of the walk-in ceiling panel.

General Guidelines - Locating and Mounting Evaporator Coil (continued):

NOTE: Nylon bolts are supplied to prevent thermal transfer between the exterior of the walk-in and the interior of the walk-in. Do not use metal bolts.

➢ Lift the evaporator coil until the nylon bolts extend through the mounting brackets.
➢ Install washers and secure with nuts. Tighten until the coil is firm against the ceiling. The evaporator coil must be level.
Additional information is available in the installation manual supplied with the evaporator.

CAUTION

Failure to observe clearance and air flow requirements will result in poor system performance and premature equipment failure!

Wiring

All electrical connections and routing must comply with local and national codes. Do not modify the factory installed wiring without written factory approval. The field wiring must enter through the knockouts provided. Refer to the nameplate on the condensing or evaporator coil to determine the proper electrical power supply. Wire type should be of copper conductor only and properly sized to handle the electrical load. The unit and coil must be properly grounded. Condensing unit wiring diagrams are located inside this installation manual and attached inside the electrical box cover. Evaporator coil wiring diagrams are located inside this installation manual and inside the evaporator cover.

WARNING

All wiring must comply with local and national codes. Wiring must be performed only by a refrigeration technician or certified electrician. Failure to follow these guidelines may result in injury!

AVERTISSEMENT

Check all wiring connections, including factory terminals, before operation. Connections can become loose during shipment and installation.

MISE EN GARDE

General Requirements:

All refrigeration piping and components are to be installed in accordance with applicable local and national codes and in conformance with industry refrigeration guidelines to ensure proper operation of the refrigeration system. Only refrigeration grade copper tubing should be used. Long radius elbows should be used. Short radius elbows have points of excessive stress concentration and are subject to breaking at these points, do not use short radius elbows. Suction lines must be insulated with a minimum 34 " thick insulation tubing to reduce heat pick-up.

Cleanliness:

Condensing units and evaporator coils are cleaned and dehydrated at the factory. The condensing unit must remain closed and pressurized until the piping is complete and final connections are ready to be made.

CAUTION

The maximum air exposure for dehydrated condensing units is 15 minutes. Systems exposed longer than 15 minutes must have the compressor oil and drier filter replaced. Leaving a system exposed to the atmosphere for more than 15 minutes can result in premature system failure.

MISE EN GARDE

Do not remove base mount valve covers until work is ready to be performed. Ensure that all refrigeration tubing is clean and dry prior to installation. Use only tubing cutters when trimming tubing to the proper length. Do not use saws to cut tubing.

CAUTION

The use of saws to cut tubing can contaminate the system with copper chips causing premature system failure.

MISE EN GARDE

Brazing joints require a dry inert gas, typically nitrogen, be passed through the lines at a low pressure to prevent scaling and oxidation. Use only silver solder brazing alloys. Minimize the amount of flux to prevent internal contamination. Flux only the male portion of the joint. Thoroughly clean fluxed joints after brazing.

CAUTION

Dry inert gas must be passed through the system while brazing to prevent scaling and oxidation. Scaling and oxides can clog refrigeration components resulting in system failure.

MISE EN GARDE

All tubing should be supported in a least two locations (near the end of each tubing run). Long runs will require additional support. As a guide, support 3/8" to 7/8" pipe every five feet, 1-1/8" to 1-3/8" every seven feet, and 1-5/8" to 2-1/8" every ten feet. Do not leave a corner unsupported when changing directions. Place supports within 2 feet of each direction change. Piping that is attached to a vibrating object (such as a compressor or compressor base) must be supported in a manner that will not restrict the movement of the vibrating object. Rigid mounting will fatigue the tubing causing refrigerant leaks.

Oil Traps:

To ensure proper oil return to the compressor, a P-type oil trap should be installed at the base of each suction riser of four feet or more. The suction trap must be the same size as the suction line. Additional traps are necessary for long vertical risers. Add a trap for each length of pipe (approximately 20 feet) to insure proper oil return. Suction lines must slope 14 per 10 feet toward the compressor. Install a suction line trap at the evaporator outlet if the suction line rises to a point higher than the connection on the evaporator.

CAUTION

Failure to properly install oil traps can prevent sufficient oil return to the compressor resulting in premature compressor failure.

MISE EN GARDE

Pressure Regulating-Relief Valves:

WARNING

Do not defeat, cap, add piping to the outlet of the valve, or, attempt to change the relief setting.

AVERTISSEMENT

Evaporator coil drain lines should be pitched a minimum of 1/2" per foot to allow proper drainage and exit the walk-in as quickly as possible. Insulate and seal the drain line where it passes through the wall. Copper drain line is required. Freezer compartment drain lines must have heat tape wrapped around the copper drain line and must have 34 " thick insulation tubing. Do not locate drain line P-traps within the freezer space. Do not reduce the drain line size. Locate a drain line P-trap outside of the cooler space. Any outdoor P-traps exposed to low ambient temperatures should be wrapped with a drain line heater (provide 20 watts of heat per foot of drain line at 0°F, 30 watts per foot at -20°F. Freezer/cooler combo boxes can have one common drain line. However, there must be a P-trap located between the freezer evaporator and the cooler evaporator located inside the cooler compartment. The cooler compartment P-trap should be located between the cooler evaporator and the external drain location.

Pre-Charged lines and Quick Connects:

Route the suction and liquid line sets between the condensing unit and evaporator coil following the piping guidelines identified in this manual. Remove the dust caps from the quick connect fittings and verify that the o-rings are intact. Wipe the coupling seals and threaded surfaces with a clean cloth to prevent contamination. Lubricate the threads and o-rings with Polyol Ester oil. Thread the coupling halves together by hand to ensure proper thread mating. Tighten with a wrench until the coupling bodies “bottom” or until there is definite resistance. Tighten an additional 14 turn to ensure proper brass-to-brass seating. Once the system is opened and pressurized, check each fitting for refrigerant leaks. If a leak is detected, tighten until the leak stops.

Leak Testing

After all connections are complete the refrigeration system must be tested for leaks. Failure to perform a leak test can result in unsatisfactory system performance, additional servicing and service costs, and possible system failure. Leak test should be performed using an electronic leak detector. All joints and components, both factory and field installed, should be thoroughly inspected for leaks. The system installation must be leak free!

Leak Testing "PR" model systems:

• Open both the liquid and suction service valves.
  ➢ Ensure the solenoid valve is energized and open.
  ➢ Add 50 psi refrigerant, then pressurize with dry nitrogen to the low side test pressure identified on the unit rating label.
• Allow thirty minutes for refrigerant to reach all parts of the system.
  ➢ Check all joints and components with an electronic leak detector.

Leak Testing "PC" model systems:

Leave the service valves closed, the condensing unit is charged with refrigerant.
➢ Ensure the solenoid valve is energized and open.
➢ Add 50 psi refrigerant, then pressurize with dry nitrogen to the low side test pressure identified on the unit rating label.
- Allow thirty minutes for refrigerant to reach all parts of the system.
➢ Check all joints and components with an electronic leak detector.

Leak Testing "PCL" model systems:

• Open both the liquid and suction service valves.
  ➢ Ensure the solenoid valve is energized and open.
• Allow thirty minutes for refrigerant to reach all parts of the system.
  ➢ Check all joints and components with an electronic leak detector.

If a leak is detected, relieve the pressure and/or reclaim the refrigerant and repair the leak. If additional brazing is required, pass a dry inert gas (nitrogen) through the system to prevent contamination. Reference page 12 of this manual for leaks located at quick connects couplings. Retest the system as outlined above until no leaks are detected.

NOTE: R448 refrigerant is a blend and when leaks occur, it is unknown which refrigerant blend or how much of it has escaped. If R448 refrigerant is simply “topped off”, the new blend mixture may affect proper performance of the system.

CAUTION

If a braze joint is detected leaking, dry inert gas must be passed through the system while repairing the joint to prevent scaling and oxidation. Scaling and oxides can clog refrigeration components resulting in system failure.

MISE EN GARDE

Always use the system specified refrigerant when pressuring to perform a leak test.

MISE EN GARDE

Evacuation of the refrigeration system is necessary to remove all air and moisture from the system. A reliable rotary vacuum pump with an accurate deep vacuum gauge is recommended. Do not use the system compressor as a vacuum pump and do not operate the compressor while the system is under vacuum.

Evacuation of "PR" model systems:

➢ Open both the liquid and suction service valves.
➢ Ensure the solenoid valve is energized and open.
Connect vacuum pump to the liquid and suction service valves located on the condensing unit.
➢ Evacuate the system to 250 microns and maintain for a minimum of 4 hours.
➢ Perform a vacuum decay test for a minimum of ten minutes to ensure the system is leak free and dry.

Evacuation of "PC" model systems:

Leave the service valves closed, the condensing unit has been evacuated and is charged with refrigerant.
➢ Ensure the solenoid valve is energized and open.
Connect vacuum pump to the liquid and suction service valves. located on the condensing unit.
➢ Evacuate the system to 250 microns and maintain for a minimum of 4 hours.
➢ Perform a vacuum decay test for a minimum of ten minutes to ensure the system is leak free and dry.

Evacuation of "PCL" model systems:

- “PCL” systems do not require evacuation.

CAUTION

Do not use the system compressor to evacuate the system. Do not start the compressor while the system is under vacuum. This may damage to the compressor and cause premature system failure.

MISE EN GARDE

Refrigerant Charging

The refrigerant charge should be added to the system through the liquid line service valve located on the condensing unit. Do not charge liquid refrigerant into the suction service valve! The initial charge should be determined by weight and sight glass indication. Start the system. If the condensing temperature is 105^ F or greater, charge the system until the sight glass clears. If the condensing unit temperature is below 105^ F, reduce the condenser face surface area to raise the discharge pressures above 105^ F and to charge to a clear sight glass. Return to a full condenser face area when charging is complete.

NOTE: PC & PCL refrigerant charge amounts are based on average ambient operating temperatures across the United States. Any refrigerant amount added or removed based on ambient operating temperatures is considered part of normal maintenance and is not covered under warranty.

CAUTION

Do not charge liquid refrigerant into the suction service valve located on the condensing unit. Do not overcharge the system. These conditions can permit liquid refrigerant to enter the compressor and cause damage to internal components resulting in premature system failure.

MISE EN GARDE

* NOTES:
1. Sizes that are highlighted indicate maximum suction line sizes that should be used for risers. Riser size should not exceed horizontal size. Properly placed suction traps must also be used for adequate oil return.
All sizes shown are for O.D. Type L copper tubing.
2. Suction line sizes selected at pressure drop equivalent to 2^ F. Reduce estimate of system capacity accordingly.
3. Recommended liquid line size may increase with reverse cycle hot gas systems.
4. If system load drops below 40% of design, consideration to installing double suction risers should be made.

Operational Start-Up

The first 2 – 4 hours of operation after initial start-up is a critical time. Do not just start the system and leave. Pressure values, compressor and evaporator superheat, and inspecting for excessive vibrations and loose connections are some of checks that must be performed prior to leaving the system.

Pre-Start Checks:

▶ Verify that all service valves are fully open.
➢ Ensure that all refrigerant and electrical connections are tight.
➢ Verify that the wiring and piping is properly routed and secured.
The compressor mounting bolts are properly adjusted (see compressor mounts on page 18).
All fan motors and mounting brackets are tight.
The condensing unit base and evaporator coil are properly secured.

Compressor Mounts:

Hermetic Compressors – hermetic compressor springs are mounted internally; check the compressor mounting bolts to ensure the nuts have not become loose during shipment.

Semi-Hermetic Compressors – most semi-hermetic compressors have external spring mounts and are factory assembled. The following actions are required once the condensing unit is installed and before system start-up:

➢ Loosen the upper mounting nuts.
Remove the spring steel clips from the mounting springs.
Retighten the upper mounting nuts until the compressor can float on the springs approximately 1/16" between the mounting nut and rubber grommet.

Compressor Mounts (continued):

Mounting Stud Mounting Nut (Upper) Compressor Mounting Foot Rubber Spacer Mounting Spring Mounting Base Locking Device Mounting Nut (Lower) Properly Adjusted Compressor Mount

CAUTION

Failure to ensure the compressor mounts are properly tightened can result in fatigue to the system piping causing leaks and poor system performance.

MISE EN GARDE

Do not start the system while in a vacuum. Do not leave the system unattended until normal operating conditions are achieved.

MISE EN GARDE

Start-Up Procedure (continued):

Operate the system for a minimum of two hours and perform checks of the following:

➢ Check the compressor discharge and suction pressures to ensure they are in the normal operating range.
➢ Check the liquid line sight glass for proper refrigerant charge (based off of 105^ F condenser coil).

Monitor the compressor oil level (semi-hermetic compressors), add oil as necessary to keep the level at 34 sight glass when idle and 12 sight glass when running.

➢ Check the voltage and amperage at the compressor terminals. Voltage must be within +10% or -5% of the rating indicted on the condensing unit name plate. On three phase compressors, verify there is a balanced load.
➢ Check all fans on the evaporator coil and condensing unit to be sure they are operational and turning in the correct direction.
➢ Check the piping and electrical connections for vibration. Add supports and strapping if needed.
➢ Check the crankcase heater operation (if equipped).
➢ Set the defrost control time and verify the defrost initiation settings. See pages 28-30 for additional details.
➢ Set temperature control to desired temperature range.
➢ Check the compressor and evaporator superheat (reference pages 21-23).

After all system checks have been checked, properly adjusted, and verified, replace all Schrader caps, service valve caps, electrical box covers, housings, etc. File a copy of this manual for future reference.

CAUTION

Failure to check and properly adjust compressor superheat can result in premature system failure.

MISE EN GARDE

Compressor Superheat:

Compressor superheat is a critical value that must be checked. Check the compressor superheat as follows:

1. Determine the suction pressure at the suction service valve of the compressor.

2. Determine the saturation temperature at the observed suction pressure using refrigeration pressure temperature tables.

3. Measure the suction line temperature 6 -10 inches away from the compressor.

4. Subtract the saturation temperature (step 2) from the measured temperature (step 3). The difference is the superheat of suction gas.

A low suction superheat can cause liquid to return to the compressor. This will cause dilution of the oil and eventual failure of the bearings, rings and valves. A high suction superheat will cause excessive discharge temperatures, which cause a breakdown of the oil. This causes piston ring wear, and piston and cylinder wall damage. System capacity decreases as the suction superheat increases. For maximum system capacity, keep the suction superheat as low as practical. Copeland requires a minimum compressor superheat of 20^ F; however, to improve compressor life, 25^ F to 40^ F is preferred. Adjust the expansion valve at the evaporator when adjustments to the suction superheat are necessary. Refer to “Evaporator Superheat” on the next 2 pages for more information.

CHECK THE TEMPERATURE AND PRESSURE, THEN CONSULT A PRESSURE/TEMPERATURE CHART. TEMPERATURE MINUS PRESSURE CONVERTED TO TEMPERATURE EQUALS SUPERHEAT. PT CHART TEMPERATURE PRESSURE DETERMINING COMPRESSOR SUPERHEAT

Evaporator Superheat:

Check the evaporator superheat once the walk-in has reached the desired temperature. Generally, systems with a design temperature drop of 10^ F should have an evaporator superheat value of 6^-10^ F on freezers and 8^-12^ F on coolers for maximum efficiency.

To determine the evaporator superheat:

1. Measure the suction pressure at the evaporator outlet.
2. Convert the pressure to saturation temperature referencing a temperature-pressure chart.
3. Measure the temperature of the suction line at the expansion valve bulb. Ensure the bulb is mounted at the correct location on the suction tube.
4. Subtract the saturation temperature reading (step 2) from the measured temperature (step 3). The difference is the evaporator superheat.

Determining Evaporator Superheat

Temperature minus pressure converted to temperature equals superheat BULB AND CONTACT LOCATION Pressure THE BULB SHOULD NEVER BE PLACED ON A COUPLING OR OTHER OBSTRUCTION SO AS TO NOT MAKE 100% CONTACT WITH THE SUCTION LINE. THE BULD SHOULD ALSO NEVER BE PLACED ON A TRAP, OR DOWNSTREAM OF A TRAP IN THE SUCTION LINE. LOCATING THE BULD AT THE TOP OR BOTTOM OF THE SUCTION LINE IS NOT RECOMMENDED. THE BULD SHOULD BE LOCATED AT THE 3:00, 4:00, 8:00 OR 9:00 POSITION ON THE SUCTION LINE.

CAUTION

Minimum compressor superheat of 20^ F may override these recommendations on systems with short line runs.

MISE EN GARDE

The condensing unit must have the discharge pressure above the equivalent 105^ F condensing pressure (reference refrigerant charging on page 16).

Evaporator Superheat (continued):

MISE EN GARDE

Correct location and full contact of the expansion valve bulb is extremely important for proper system performance.

Electric Defrost Time Clock Instructions:

Instructions for setting the timer is located on the inside cover of the time clock. The defrost timer clock must be set to the correct time at initial start-up and after any power interruptions. Set the clock by rotating the clock face until the correct time is at the arrow on the face of the timer. The switch is programmed by pushing the captive trippers to the inner ring for the entire period the load is to be turned "ON". When a tripper is pushed to the outside, the switch is in the "DEFROST" position. Each defrost tripper represents 15 minutes of defrost time. The timer is factory set for four defrost cycles daily: 4:00AM, 10:00AM, 4:00PM, and 10:00PM. Each defrost cycle is programmed for 45 minutes duration. The defrost times may be changed to initiate at periods of low activity (trippers pushed out will close contacts to terminals 1 & 3).

Note: If the defrost termination thermostat fails to close, the fail safe setting on the timer will terminate the defrost cycle. The timer starts the defrost cycle automatically at the predetermined times. A setting of two to four defrost cycles per day is typical. For heavier frost loads, additional cycles may be required.

When the defrost cycle begins:

1. Switch 2 to 4 opens in the time clock, breaking the circuit to the room thermostat, liquid line solenoid, and evaporator fan motors. This allows the compressor to pump down and shut off. Simultaneously, switch 1 to 3 closes in the timer, energizing the defrost heaters.
2. The heaters increase the coil temperatures above 32°F, melting the frost off the coil.
3. When the coil warms to approximately 55^ F, the defrost termination thermostat closes and energizes the switching solenoid in the timer. At this time, switch 1 to 3 in the timer opens, terminating the defrost heaters. Simultaneously, switch 2 to 4 closes in the time clock, energizing the temperature control circuit.
4. Suction pressure rises, the low pressure control closes, and the compressor starts.
5. The fan relay closes when the coil temperature reaches approximately 30^ F. This energizes the fan motors.
6. The system operates in the refrigeration cycle until another defrost cycle is initiated by the timer.

Failure to keep the condenser coil clean will result in reduced airflow through the condenser, resulting in poor system performance and premature compressor failure.

MISE EN GARDE

Polyol Ester (POE) Lubricants:

Polyol Ester (POE) lubricants quickly absorb moisture from the ambient surroundings. POE lubricants absorb moisture more rapidly and in greater quantity than conventional mineral oils. Because moisture levels greater than 100 PPM will result in system corrosion and component failure, it is essential that system exposure to ambient conditions be kept to a minimum.

If a system is left open to the atmosphere for more than 15 minutes, the liquid line drier and compressor oil must be replaced. Drain at least 95% of the oil from the compressor suction port. Measure the amount of removed oil, and replace it with exactly the same amount of new POE oil. Mobil EAL™ ARCTIC 22 CC is the preferred Polyol Ester

Polyol Ester (POE) Lubricants (continued):

lubricant because of its particular additives. ICI Emkarate RL 32S is an acceptable alternative when the Mobil is not available. These POE lubricants must be used with HFC refrigerants. Lubricants are packaged in specially designed, sealed containers. Once opened, use the lubricant immediately. Properly dispose of any unused lubricant.
