START--UP PRE--START--UP WARNING FIRE, EXPLOSION, ELECTRICAL SHOCK AND ENVIRONMENTAL HAZARD Failure to follow this warning could result in personal injury, death or property damage. 1. Follow recognized safety practices and wear protective goggles when checking or servicing refrigerant system. 2. Relieve and recover all refrigerant from system before touching or disturbing compressor plug if refrigerant leak is suspected around compressor terminals. 3.

Step 2 — Start--Up Adjustments Complete the required procedures given in the Pre--Start--Up section before starting the unit. Do not jumper any safety devices when operating the unit. Do not operate the unit in Cooling mode when the outdoor temperature is below 40_F (4_C) (unless accessory low--ambient kit is installed). IMPORTANT: Three--phase, scroll compressors are direction oriented. Unit must be checked to ensure proper compressor 3--phase power lead orientation.

Two Cooling Fan Speeds Set-up (Dehumidification feature used) IMPORTANT: Dehumidification control must open control circuit on humidity rise above set point. Use of the dehumidification cooling fan speed requires use of either a 24 VAC dehumidistat or a thermostat which includes control of a 24 VAC dehumidistat connection. In either case, the dehumidification control must open the control circuit on humidity rise above the dehumidification set point. 1. Using Fig.

MAINTENANCE Indoor Blower and Motor To ensure continuing high performance, and to minimize the possibility of premature equipment failure, periodic maintenance must be performed on this equipment. This heat pump unit should be inspected at least once each year by a qualified service person. To troubleshoot unit, refer to Table 11. NOTE: TO EQUIPMENT OWNER: Consult your local dealer about the availability of a maintenance contract.

Inspect the condenser coil, evaporator coil, and condensate drain pan at least once each year. The coils are easily cleaned when dry; therefore, inspect and clean the coils either before or after each cooling season. Remove all obstructions, including weeds and shrubs, that interfere with the airflow through the condenser coil. Straighten bent fins with a fin comb. If coated with dirt or lint, clean the coils with a vacuum cleaner, using the soft brush attachment. Be careful not to bend the fins.

Compressor Oil The Copeland scroll compressor uses 3MAF POE oil. If additional oil is needed, use Uniqema RL32--3MAF. If this oil is not available, use Copeland Ultra 32 CC or Mobil Arctic EAL22 CC. This oil is extremely hygroscopic, meaning it absorbs water readily. POE oils can absorb 15 times as much water as other oils designed to HCFC and CFC refrigerants. Take all necessary precautions to avoid exposure of the oil to the atmosphere.

R--410A QUICK REFERENCE GUIDE R--410A refrigerant operates at 50--70 percent higher pressures than R--22. Be sure that servicing equipment and replacement components are designed to operate with R--410A S R--410A refrigerant cylinders are rose colored. S S S Recovery cylinder service pressure rating must be 400 psig, DOT 4BA400 or DOT BW400. R--410A systems should be charged with liquid refrigerant.
