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

Best Practice: Coil excess

tubing inside the building in a

horizontal coil.

Minimize tubing routed

outside of the controlled

space.
