FOR THE INSTALLER: Remote Condenser
Location
Limited to a 40 foot or a 25 foot length of
precharged refrigerant tubing connecting the ice
machine to the remote condenser. The condenser
must be above or level with the ice machine.
Select the best available location, protecting the
condenser from extremes of dirt, dust, and sun.
Meet all applicable building codes. Usually the
services of a licensed electrician are required.
Roof Attachment
1. Install and attach the remote condenser to the
roof of the building, using the methods and
practices of construction that conform to the local
building codes, including having a roofing
contractor secure the condenser to the roof.
2. Have an electrician connect the remote
condenser fan motor to the ice machine, using the
junction box at the back of the ice machine.
PRECHARGED LINE ROUTING
CAUTION
Do not connect precharged tubing until all routing
and forming of the tubing is complete. See the
coupling instructions for connecting information.
1. Each set of precharged refrigerant lines (either
25 foot or 40 foot) consists of a 3/8 inch diameter
liquid line and a 1/2 inch diameter discharge line.
Both ends of each line have quick connect
couplings, one end has a schrader valve
connection, that end goes to the condenser.
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 inch. Check local
codes, a separate hole may be required for the
electrical power to the condenser.
CAUTION
DO NOT KINK OR CRIMP REFRIGERANT
TUBING WHEN INSTALLING IT.
3. Route the refrigerant lines through the roof
opening.
Follow straight line routing whenever possible.
Any excess tubing MUST be retained within the
building.
4. Spiral the excess length of pre charged tubing
inside the building. Use a horizontal spiral (need
not be as tight as illustrated) to avoid any traps in
the lines.
5. Have the roofing contractor seal the holes in the
roof per local codes.
CAUTION
The couplings on the sets of precharged lines are
self sealing when installed properly. Carefully
follow the instructions:
