Installation: Remote Condenser System
Remote Condenser
The remote condenser may be located within 100
equivalent feet of the ice machine (per the
formula). Follow all local building codes for the
condenser’s location. If placed on a roof, a roofing
specialist should install it.
Precharged Lines
There are two precharged lines required for each
ice machine to condenser connection: a 1/4" liquid
line and a 3/8" discharge line (the discharge line is
insulated). Each contains a minor holding charge
that matches the type of refrigerant in the ice
machine and in the condenser. The ice machine
contains the entire system charge in the receiver.
From the formula, plan the routing of the tubing.
Do not leave any excess tubing on the roof: the
condenser must be located as close as possible to
the place where the tubing goes through the roof.
Route the tubing to the condenser and to the ice
machine. Be certain that there is no metal to metal
or tight tube to tube contact between the liquid and
discharge lines.
Coil excess tubing inside the building in a
horizontal spiral.
If there is considerable excess tubing, it should be
cut out before the tubing is connected to the ice
machine. Be certain to evacuate the tubing before
connecting to the ice machine or to the remote
condenser.
Connections:
Remove plastic caps from condenser, tubing
connections and from the ice machine’s refrigerant
tubing connections. Lubricate all threads and
o-rings with refrigeration oil.
Tighten all fittings until a significant resistance is
felt. Then using two wrenches, (one holding the
tubing so that it does not rotate) tighten the
connections 1/4 turn more.
Check fittings for leaks and have the roof hole
sealed.
Wiring:
The remote condenser fan motor takes its power
from the ice machine. Wire per electrical codes
and the wiring diagram.
