7.3.2Quick Connect Fittings

NOTE

When hard piping is used, complete all piping and evacuate lines before connecting quick connects.

Be especially careful when connecting the quick connect fittings. Read through the following steps before making the connections.

1.Remove protector caps and plugs.

2.Carefully wipe coupling seats and threaded surfaces with a clean cloth.

3.Lubricate the male diaphragm and synthetic rubber seal with refrigerant oil.

4.Thread the coupling halves together by hand to ensure that the threads mate properly.

5.Tighten the coupling body hex nut and union nut with the proper sized wrench until the coupling bodies “bottom out” or until a definite resistance is felt.

6.Using a marker or pen, make a line lengthwise from the coupling union nut to the bulkhead.

7.Tighten the nuts an additional quarter turn; the misalignment of the lines shows how much the coupling has been tightened. This final quarter turn is necessary to ensure that the joint will not leak. Refer to Table 24 for torque requirements.

8.Add charge for the additional piping (refer to Table 22).
