INSTRUCTIONS FOR PRE-CHARGED LINES - REMOTE SYSTEMS
By employing self-sealing refrigeration couplings, the condensing unit section, evaporator section, and the
connecting tubing are separately pre-charged with refrigerant and leak tested at the factory before shipment.
Follow steps 1-8 below to install the connecting tubing at both the condensing unit and the evaporator section.
1. Carefully uncoil the suction line. This is the line covered with a continuous
length of sponge rubber insulation.
2. Carefully uncoil the liquid line. The liquid line is the smaller diameter, bare
copper tube.
3. Before making any connections, determine the routing of both lines and
carefully hand bend them to suit the situation. Keep any bend radius rather
large to prevent kinking the tubing. It is a general practice to route the suction
and liquid line parallel and close together in the installation.
4. Remove the dust caps and plugs from the couplings and inspect them to
see if the synthetic seals are intact.
5. Using a clean cloth, wipe the coupling seals and threaded surfaces to
prevent the inclusion of any dirt or foreign material in the system.
6. LUBRICATE the synthetic seal in the male half of the couplings with
refrigeration oil and thread the two coupling halves together BY HAND to insure
proper mating of the threads. Note: Make certain that the insulated suction line
is connected to the coupling half marked "Suction Line" and that the bare tube
liquid line is connected to the coupling half marked "Liquid Line".
Note: Always use two wrenches on the coupling body hex nut and on the union
to prevent twisting of the tube while tightening the connections as described in
the next step.
7. Using the proper size wrench on the union nut, tighten until the coupling
bodies bottom, or until a definite resistance is felt. Tighten an additional 1/6 to
1/4 turn. This final turn is necessary to insure the knife edge metal seal bites
into the brass seat of the coupling halves, forming a leak proof joint.
