Electrical Needs
The condensing unit requires a dedicated 115 volt 20 amp circuit. The unit draws a large inrush current for about
one 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 unit (fan coil unit) 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 unit.
• Provide a dedicated circuit and circuit breaker for the condensing unit.
• Provide a weatherproof disconnect for condensing unit located outside.
As with all sensitive electrical equipment, damage may be caused in the event of power surges and spikes. WhisperKOOL
recommends plugging the unit 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.
WE RECOMMEND THAT YOU 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 section on page 48.
Low Ambient Control (Cold Weather Start)
All WhisperKOOL split systems come equipped with a compressor heater and fan regulator switch allowing the
condensing unit to operate when the ambient temperature is as low as 20°F. The heater serves to prevent liquid
refrigerant from entering the compressor while the system is not running. In addition, in cold weather conditions, the
heater keeps the condenser warm which helps to operate the system. The fan cycling switch will prevent the fan from
operating if the pressure it too low allowing the system to warm up to the needed temperature to operate effectively.
When the low ambient temperature is below 20°F an extra heat source kit is necessary to allow the condensing unit to
start up.
