Precharged Line Routing
Do not connect the precharged tubing until all
routing and forming of the tubing is complete. See
the Coupling Instructions for final connections.
1. Each set of pre-charged tubing lines contains a
3/8” diameter liquid line, and a 1/2” diameter
discharge line. Both ends of each line have quick
connect couplings, the end without access valves
goes to the ice maker.
Note: The openings in the building ceiling or wall,
listed in the next step, are the minimum sizes
recommended for passing the refrigerant lines
through.
2. Have the roofing contractor cut a minimum hole
for the refrigerant lines of 1 3/4”. Check local
codes, a separate hole may be required for the
electrical power supply to the condenser.
Caution: Do NOT kink the refrigerant tubing while
routing it.
3. Route the refrigerant tubes thru the
roof opening. Follow straight line
routing whenever possible. Excess
tubing may EITHER be coiled up
INSIDE the building OR cut out prior
to connection to the ice maker and
condenser.
If the excess tubing is cut out, after
re-brazing the tubing must be
evacuated prior to connection to the
ice maker or condenser.
If the excess tubing is to be coiled,
spiral it horizontally to avoid excess
trapping in the lines.
5. Have the roofing contractor seal the
holes in the roof per local codes
