The Kwik Charge® charging unit accepts liquid refrigerant from the cylinder and discharges into low side of the system. Charging rate is up to eight times faster than vapor charging. In addition, liquid charging is required when using R-410A and other blended refrigerants. Attach the Kwik Charge device to the low side of the charging manifold.The main reasons your compressor will have simultaneously low head pressure and high suction pressure is due to: Bad or leaky compressor valves. Worn compressor piston rings. Leaky oil separator return line. Your compressor valves may become inefficient due to poor sealing from dirt and debris deposits.Service port fitting with straight media inlet for low side Schrader port 5/16” SAE OD for evacuation / charge/ recharge of refrigerants in HVAC-R Systems."Manifold sets should be a minimum 700 psig on the high side and minimum 180 psig low side, with 550-psig low-sided retard. Use hoses with a minimum 700-psig service pressure rating." "Be sure that servicing equipment and replacement components are designed to operate with [410A]."The vapor pressure is 118 PSIG and because it is 85°F outside, the R-410A bottle pressure is 254 PSIG. The pressure in the bottle is much higher than the pressure on the low side of the system so if they are connected, refrigerant will exit the bottle and enter the system.

Step 1. Connect the red hose of the manifold gauge to the high side valve on the back of the condenser. The high side is the smaller valve. Connect the blue hose of the manifold gauge to the low side access valve (the large valve on the condenser). Video of the Day.Step 19. Close the manifold and R-410 jug's valve handles. Disconnect the hoses and reinstall the caps on the service valve's ports. Advertisement. An azeotrope refrigerant blends multiple refrigerant compounds to form a single refrigerant. Most refrigerant blends boil at different rates and require complete evacuation before adding a full charge.
