Precharged Line Routing - Remote Only
Do not connect the precharged tubing until all routing
and forming of the tubing is complete. See the
Coupling Instructions for nal 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.
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 roong contractor cut a minimum hole
for the refrigerant lines of 2”. 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.
4. 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 roong contractor seal the holes in the
roof per local codes
