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, 45, 60 or 75 foot line set lengths. The 60 foot line set will require adding an additional 16 ounces
of refrigerant to the system. The 75 foot line set will require adding an additional 28 ounces of refrigerant to
the system.
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 -20
°F (-29°C) or above 120°F (49°C).
The remote condenser functions as a normal refrigeration system until the temperature at the condenser
coil drops below 70
°F. 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). For the complete explanation of this valve, refer to the schematic on page 6 of this
manual.

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.
3. Condenser should be mounted higher than the ice
machine.
4. Condenser must be level.
5. Condenser should not be exposed to temperatures
below -20
°F or above 120°F.
6. Installation must meet all local and national building,
plumbing and electrical codes.
