Charging With Refrigerant Calculating R407C charge Use the following table and formula when calculating the total R407C charge. Condenser model LNE-S01-A009 APC SKU ACCD75201 ACCD75204 LNE-S02-A015 ACCD75202 ACCD75205 LNE-S03-A027 ACCD75203 ACCD75206 KH1180.BDVES ACCD75207 KH1280.ADVES ACCD75208 KH1280.CDVES ACCD75209 Selected Condenser ambient summer temp.
Charging the equipment Caution: This procedure is to be done by APC-trained personnel only. R407C is a blend refrigerant. When charging equipment with blend refrigerants, only liquid refrigerant must be charged. Caution: Charging with other than liquid R407C refrigerant may damage the system. 1. Ensure the ball valves are open. Service port 2. Confirm the calculated system charge. Schrader port na2455a 3. Connect the refrigerant cylinder to the charging or gauge port on the receiver outlet valve.
8. Charge the rest of the calculated liquid refrigerant very slowly through the suction port. Caution: Fast charge of liquid refrigerant through the suction port may damage the compressor. 9. Verify that the sightglass is clear. If there is excessive bubbling in the sightglass, make sure the system high side pressure is above 15.9 bar (230 psi) and Superheat and Subcooling are within parameters (10-12 for Superheat and 8-10 for Subcooling).
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. Let the compressor run at full capacity for at least one hour and check the oil level in the oil sight glass. The level should be between 1/4 and 3/4 full, or within the limit shown on the oil level sticker.
3. Purge the pump and hose: a. Ensure that the oil pump is clean. Insert the pump in the oil container and make sure that the container is open to the atmosphere for as short a period of time as possible. When available, use a plug adaptor kit to further reduce the exposure of the oil to the atmosphere. b. Bleed all air from the pump and hose with a few strokes of the pump. Purging the pump removes the moisture-saturated oil left inside the hose from previous usage. c.
