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
liquid line, and a large 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.
Minimize tubing
routed outside of
the controlled
space
2. Have the roofing contractor cut a minimum hole
for the refrigerant lines of 50 mm. 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

Best Practice: Coil
excess tubing inside the
building in a horizontal
coil.
