ABOVE UNIT=UNRESTRICTED These units use R-410A refrigerant which operates at 50 to 70% higher pressures than R-22. Use only R-410A approved service equipment. Refrigerant cylinders are painted a "Rose" color to indicate the type of refrigerant and may contain a "dip" tube to allow for charging of liquid refrigerant into the system. All R-410A systems use a POE oil that readily absorbs moisture from the atmosphere. To limit this "hygroscopic" action, the system should remain sealed whenever possible. Never break a vacuum with air and always change the driers when opening the system for component replacement. Check for transportation damage after unit is uncrated. Report promptly, to the carrier, any damage found to the unit. To determine the electrical power requirements of the unit, refer to the nameplate of the unit. The electrical power available must agree with that listed on the nameplate. B. LOCATION & PREPARATION OF THE UNiT 1. When removing unit from the pallet, the basepan.
