Pre-Charged lines and Quick Connects
•
Route the suction and liquid line sets between the condensing unit and evaporator coil following the piping guidelines
identified in this manual.
Remove the dust caps from the quick connect fittings and verify that the o-rings are intact.
•
•
Wipe the coupling seals and threaded surfaces with a clean cloth to prevent contamination.
•
Lubricate the threads and o-rings with Polyol Ester oil.
Thread the coupling halves together by hand to ensure proper thread mating.
•
Tighten with a wrench until the coupling bodies "bottom" or until there is definite resistance.
•
Tighten an additional ¼ turn to ensure proper brass-to-brass seating.
•
Once the system is opened and pressurized, check each fitting for refrigerant leaks. If a leak is detected, tighten until
•
the leak stops.
Do not loosen and disconnect the quick connect fittings before reclaiming the refrigerant and depressurizing the
system. Disconnecting a pressurized system can result in injury!
