Installation Clearances NOTE: These units require special location consideration in areas of heavy snow accumulation and/or areas with prolonged continuous subfreezing temperatures. Heat pump unit bases have cutouts under the outdoor coil that permit drainage of frost accumulation. Situate the unit to permit free unobstructed drainage of the defrost water and ice. A minimum 3" clearance under the outdoor coil is required in the milder climates.

Three Phase Compressor Rotation CAUTION Use care when handling scroll compressors. Dome temperatures could be hot. Three phase compressors are power phase dependent and can rotate in either direction. Verify proper rotation for three phase compressors by ensuring the suction pressure drops and discharge pressure rises when the compressor is energized. NOTE: When operated in reverse, a three phase scroll compressors is noisier and its current draw substantially reduced compared to marked values.

Charge Verification CAUTION POSSIBLE REFRIGERANT LEAK To avoid a possible refrigerant leak, open the service valves until the top of the stem is 1/8” from the retainer. WARNING REFRIGERANT UNDER PRESSURE! • Do not overcharge system with refrigerant. • Do not operate unit in a vacuum or at negative pressure. Failure to follow proper procedures may cause property damage, personal injury or death. NOTICE REFRIGERANT MUST BE ADDED TO THE SYSTEM AFTER EVACUATION IS COMPLETE.
