WhisperKOOL Quantum Cooling Unit Owner's Manuals

Owner's Manuals and installation information for WhisperKOOL Quantum Split Cooling Units

Described in the simplest terms, a split system means that the two essential parts of a cooling system (the evaporator unit and the condensing unit) have been separated, or “split” into their own respective units. The evaporator unit is located in or near your cellar, and the condensing unit is generally located outdoors or in an attic or utility room.

The Quantum Series of cooling units are the highest-capacity units that we offer. KOOL your collection with our trusted name.

Quantum Series units are available with a 110v or 220v High Efficiency Condenser and 24v thermostat option.


  • A qualified HVAC-R technician is required for installation. Failure to have the system installed by a qualified technician will void the warranty
  • The use of the 24-volt thermostat conversion kit eliminates the thermostat normally included with the system and allows your contractor to select, purchase and install the thermostat technology of your choice, including but not limited to Nest, Ecobee, and Honeywell. By selecting the 24V Thermostat Conversion Kit, you have acknowledged that the system will not be built with the standard WhisperKOOL control or liquid measuring bottle probe. You will have to source and purchase your own 24V thermostat to run the equipment.
