PREPARING THE CONDENSING UNIT
Electrical Needs
The condensing unit requires a dedicated 230V single-phase 20-amp circuit . The unit draws a large inrush current for about
1 second the instant the compressor starts . With a dedicated circuit and circuit breaker, the condensing unit will have sufficient
power for effective operation . (The compressor is controlled by a low-pressure switch mounted on the condensing unit . This
feature eliminates the need for wiring between the evaporator units and the condensing unit .)
•
Ensure the voltage supplied matches the rating specified on the unit spec label .
•
Provide a non-GFI dedicated circuit and an appropriate outlet for the evaporator units .
•
Provide a dedicated circuit and circuit breaker for the condensing unit .
•
Provide a weatherproof disconnect for the condensing unit if it is located outside .
Power surges and spikes can damage sensitive electrical equipment . CellarCool recommends plugging the system into a surge
protector or power conditioner in order to protect your system . As outlined in our terms and conditions, power surges and spikes
are not covered under warranty .
DO NOT USE A GROUND FAULT INTERRUPTER (GFI) WITH THIS PRODUCT.
In case the system should lose power, check the home/main circuit breaker . If the system does not respond properly, refer to the
Troubleshooting Guide on page 44 .
The condensing unit can be installed inside a well-ventilated area of the home, but is typically installed outside . Exterior
applications will require the use of a protective housing . The amount of sun exposure should be considered when selecting
the placement of the condensing unit .The condensing unit requires a dedicated 20-amp circuit (non-GFI) . Make sure there is
a minimum of three (3) feet of horizontal clearance in every direction around the unit (five feet is ideal) . The unit may either be
hard-wired or plug-in, depending on local electrical codes .
Indoor condensing unit installations: Inside installations require special consideration, as there must be adequate
ventilation to remove the heat created during normal operations . An exhaust port with fan may need to be installed to
ensure that heat is effectively removed from the utility room . There must be a return grille or provision for 500-600 CFM
of cool air to enter the room to replace the exhausted air . Unobstructed airflow to and from the unit is a critical factor in
the unit’s overall performance . Make sure there is a minimum of three (3) feet of horizontal clearance in every direction
around the unit (five feet is ideal) . This will assure that the unit can move the air around the room in an efficient manner .
Outdoor condensing unit installations: You must utilize the exterior condensing unit housing for outdoor installations .
Place the condensing unit on a solid foundation in a location with adequate ventilation . Make sure there is a minimum of
three (3) feet of horizontal clearance in every direction around the unit (five feet is ideal) . The unit should be elevated 18
inches in order to avoid any possible flooding or damage by animals, and should be clear of leaves, dirt, and other debris .
