We have created a ceiling-mounted split system evaporator because we want you to experience KOOL without seeing it. Your wine should be the center of attention, not a cooling unit. Technicians and installers will be happy to hear that the electrical wiring, bottle probe wiring, and the line set are all located at the bottom of the unit, rather than the top. Not only are the essential components relocated and easier to access, flare fittings will now be utilized so that there is no brazing needed in the field. The redesign includes e-coated duramax evaporator coils which will improve system performance, a 2-speed fan switch that will decrease noise levels up to 7 dbs, and a new looking hex mesh grille with an air filter to protect the unit from the intake of potentially harmful debris during the initial start-up. Note: A qualified HVAC-R technician is required for installation. Failure to have the system installed by a qualified technician will void the warranty. *PLEASE NOTE: WhisperKOOL does not provide smart thermostat. 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 smart thermostat to run the equipment. The WhisperKOOL Customer Satisfaction Team does not provide technical support for smart thermostats.
