ABOUT QUICK CONNECT COUPLINGS
Quick Connect fittings are provided on
both the case inlet and outlet lines, and on
Hussmann’s Freedom Line con densing units.
The case and condensing unit are pre-charged
with the correct amount of refrigerant, and
the lines are sealed. Connecting the Quick
Connects together breaks the seals to connect
the refrigeration lines of the unit to the case.
The Quick Connects must be properly torqued
to avoid refrigerant leaks.
CONNECT LINES
Mount the suction line and liquid line to the
condensing unit. When ready to connect,
remove protector caps and plugs from the
Quick Connect couplings.
If necessary, carefully wipe coupling seats and
threaded surfaces with a clean cloth to prevent
the inclusion of dirt or any foreign material in
the system.
Lubricate male half diaphragm and synthetic
rubber seal with refrigerant oil. Thread the
coupling halves together by hand to ensure
proper mating of threads. Use proper size
wrenches (on coupling body hex and on
union nut) and tighten until coupling bodies
“bottom” or a definite resistance is felt.
Step 1:
Remove protector caps and plugs from the
line couplings, Apply refrigerant oil to the
entire surface of diaphragm, o-ring and
threaded area of male coupling assembly.
The amount of lubricant used must cover
all designated surfaces sufficiently. Ideal
application is a small applicator brush
saturated with lubricant and applied, liberally.
Apply supplied Oil to Threads, O-rings,
and Diaphragm.
