Coupling Connections:
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.
Clean and Lubricate Couplings
2. Thoroughly and completely lubricate the
threads, o-rings, diaphragms and all internal
coupling surfaces with polyolester refrigerant oil.
3. Position the fittings on the correct connections
on the condenser and ice machine.
Final Connections:
4a. Begin to tighten the couplings together by
hand. Be sure they are not cross-threaded.
Continue to turn the swivel nuts by hand until it is
certain that the threads are properly engaged.
4b. Using two wrenches, one to rotate the swivel
nut and one to hold the tubing in place, tighten
each coupling.
It is CRITICAL that ONLY the NUT on the
pre-charged tube be turned, or the diaphragms will
be torn by the piercing knives and become loose in
the refrigeration system causing severe
operational problems.
Note: As the coupling is tightened, the diaphragms
in the quick connect couplings will begin to be
pierced. As that happens, there will be increased
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).
Do NOT overtighten.
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.
Rotate Swivel Nut ¼ Turn More
6. After all connections have been made check the
couplings for leaks.
7. Add cork tape to the swivel nut of the suction
line to insulate it. Be sure all exposed tubing of
the suction line is insulated.
Note: The system charge is contained in the
receiver tank of the ice machine. Only "holding"
charges are present in the "pre-charged" tubing or
the condenser.
