Remote Condenser

14.Turn machine on and check for proper voltage and amp draw on the entire unit as well as components such as the gearmotor and fan motor.

15.Check refrigerant circuit and all plumbing connections for leaks, etc.

16.Check bin thermostat or mechanical shut–off for proper operations. In the mid–range the bin thermostat will open at 42° and has a 6° differential.

Remote condensers should be installed above the ice machine and in a level configuration. They are connected to the ice making unit by copper tubing and line valves. The female half of the line valve is mounted on the ice making unit and the remote condenser. The male half is soldered on the tube ends when tubing kits are provided with the machine. If tubing kits are not provided, the male half of the line valves will be provided in a valve kit and the installer will mount them on the tubing he provides.

NOTE: WHEN VERTICAL LINES ARE INVOLVED IN THE INSTALLATION, FOLLOW STANDARD REFRIGERATION PRACTICES FOR VERTICAL LINES TO ASSURE POSITIVE OIL RETURN TO THE COMPRESSOR. VERTICAL LIFT TO BE NO MORE THAN 15 FEET.

NOTE: WE DO NOT RECOMMEND TUBING RUNS OF MORE THAN 40 FEET..

NOTE: The seals for the line valves will be found in an envelope on the remote condenser. Make sure they are used.

NOTE: REMOVE CAP PLUGS FROM ALL LINE VALVES BEFORE MAKING VALVE CONNECTIONS WITH THE SEAL.

NOTE: A LOW VOLTAGE ELECTRICAL CONTROL CIRCUIT MUST BE FIELD WIRED BETWEEN THE ICE MACHINE AND THE REMOTE CONDENSER RELAY. THOSE WIRES SHOULD BE RUN WITH THE TUBING DURING INSTALLATION. REFER TO APPLICABLE WIRING DIAGRAMS.

NOTE: When the line valves are connected to each other the refrigerant circuit is complete. Each valve half has its own shut-off which must be fully opened to allow the refrigerant to flow though the system before it is started.

The ice making unit utilizing a remote condenser is shipped from the factory with the receiver holding the refrigerant charge. Additional refrigerant may be required upon installation depending upon the ambient conditions the remote condenser is operating under, the condenser and line sizing.

A three way head pressure control valve is used to maintain a relatively consistent head pressure between 175 and 185 PSI for R22 in the receiver in cold ambient conditions. Because of this valve some liquid refrigerant will be held in the condenser.

NOTE: THE HEAD PRESSURE CONTROL VALVE WILL NOT OPERATE CORRECTLY WHEN A TOTAL PRESSURE DROP OF 14 POUNDS OR MORE IS CREATED BETWEEN THE ICE MAKING UNIT, THROUGH THE TUBING TO THE REMOTE CONDENSER, THE CONDENSER AND THE RETURN TUBING TO THE ICE MAKING UNIT.

The remote condenser requires a separate power supply from the ice making unit. Refer to the remote condenser wiring diagram.
