Coupling Instructions

The couplings on the ends of the pre-charged line

sets are self-sealing when installed properly.

Follow these instructions carefully.

These steps must be performed by an EPA

Certified Type II or higher technician.

Initial Connections

1. Remove the protector caps and plugs. Wipe the

seats and threaded surfaces with a clean cloth to

remove any possible foreign matter.

2. Lubricate the inside of the couplings, especially

the O-rings, with refrigerant oil. Oil packets are

supplied with Scotsman line sets.

3. Position the fittings on the correct connections

on the condenser and ice machine.

1/2" discharge

•

3/8" liquid line

Final Connections:

4a. Begin by tightening the couplings together by

hand until it is certain that the threads are properly

engaged.

4b. Then using two wrenches tighten the coupling

until it bottoms out or a definite increase in

resistance is felt.

It is important that ONLY the nut on the

pre-charged tube be turned, or the diaphragms will

be torn out by the piercing knives and they will be

loose in the refrigeration system. Note: As the

couplings are tightened, the diaphragms in the

quick connect couplings will begin to be pierced. As

that happens, there will be some resistance to

tightening the swivel nut.

4c. Continue tightening the swivel nut until it

bottoms out or a very definite increase in

resistance is felt (no threads should be showing).

Critical Step!

5. Use a marker or pen to mark a line on the

coupling nut and unit panel. Then tighten the

coupling nut an additional one-quarter turn. The

line will show the amount that the nut turns. Do

NOT over tighten.

6. After all connections have been made, and after

the receiver outlet valve has been opened (do not

open yet), check the couplings for leaks.
