Charging the equipment Caution: This procedure is to be done by APC-trained personnel only. R410A is a blend refrigerant. When charging equipment with blend refrigerants, only liquid refrigerant must be charged. Caution: Charging with other than liquid R410A refrigerant may damage the system. 1. Ensure the ball valves are open. 2. Confirm the calculated system charge. 3. Connect the refrigerant cylinder to the charging or gauge port on the receiver outlet valve. Open the receiver valve approxi

Compressor Oil Charge Caution: This procedure is to be done by APC-trained personnel only. You may need to add oil to air-cooled equipment, depending on the condenser size and the lengths of tube running between the equipment and the condenser. Caution: Do not charge the compressor with too much oil, or compressor damage could result. The only way to drain oil from the compressor is to remove the compressor from the equipment, which cannot be done when the equipment is in the row. Oil chargin

2. Prepare to add oil: a. Use a new, sealed oil can and a manual oil pump. The pump hose must be sized for 1/4 in flare fittings and must include a valve depressor at its end, which will open the valve on the Schrader service port of the compressor. b. At a minimum, use a quality POE oil with a viscosity of 32 cst, 160 sus at 40°C (104°F). Suggested oils: Danfoss Maneurop 160 PZ Polyolesteroil, the approved type of oil for this equipment. Approved alternative oil types: • CPI (Lubrizol) refer
