Remote Condenser General Information

Introduction
Ice-O-Matic Remote Condenser Systems are comprised of three components. The pre-charged remote
condenser, the pre-charged ice maker and the pre-charged line set. The pre-charged line sets are available
in 25, 40, or 75 foot line set lengths.
Note: Add ¼ oz. of refrigerant for each actual foot from 75 to 100 ft. actual line set run..
Normal installation of the ice maker should be followed. Reference the installation instructions included with
the ice maker.
In any installation, the pre-charged line sets, consisting of a liquid line (3/8” dia.) and a discharge line
(1/2” dia.) are used as a one time initial charge type installation.
Once the sealed couplings are connected and the internal seal is broken, the lines cannot be disconnected
without losing the refrigerant charge. They are, however, reusable and when the couplers are removed and
reconnected, the complete refrigeration system must be evacuated and re-charged with the proper amount
of refrigerant. Reference the ice maker data plate or ice maker service manual for proper refrigerant
charge.
General Description
The remote condenser should not be used in areas where sufficient airflow is not available in the area the
ice maker is being installed or the heat being rejected by the condenser coil will be undesirable.
The condenser coil should not be exposed to temperatures below -20F (-29C) or above 120F (49C).
The remote condenser functions as a normal refrigeration system until the temperature at the condenser
coil drops below 70F. At this time the mixing valve will begin to bypass enough hot gas from the discharge
line directly into the receiver to keep the liquid line feeding the expansion valve at a steady pressure. The
amount of gas bypassed will depend on the temperature at the condenser coil (the colder the temperature
at the condenser coil, the more gas will bypass and the tubing between the mixing valve and receiver will
become warmer).
Condenser Location
When choosing a location for the remote condenser, reference
the following guidelines:
1. Choose a location that is protected from extremes of dirt,
dust, rain, sun and prevailing winds.
2. Vertical air discharge mounting of the condenser is required
with at least 48 inch clearance above the condenser
3. Condenser should be mounted higher than the ice machine.
4. Condenser must be level.
5. Condenser should not be exposed to temperatures below
-20F or above 120F.
6. Installation must meet all local and national building,
plumbing and electrical codes.
7. The condenser must have a minimum clearence of
18 inches around all 4 sides.
8. Install condenser with included legs or other elevated
mounting solution. There should be clearance between the
bottom of the condenser and the surface on which it is
mounted.
