  • Page 6: Quick Start Guide

    Pump Down Cycle CellarCool’s twin split systems operate on a pump down cycle which differs from traditional air conditioners . As such, there is no wiring between the condensing unit and evaporator units . CellarCool twin systems utilize a solenoid valve on the liquid line in each evaporator unit and a low-pressure switch on the suction line at the condensing unit .

  • Page 7: Before You Start

    . 6 . CellarCool requires that all split systems be installed by a certified HVAC-R technician only . NATE or equivalent is recommended . It is vital that the units be set apart and oriented so that the return air from one unit does not recirculate into the supply air of the other unit.

    LIQUID-MEASURING THERMOSTAT SYSTEM (BOTTLE PROBE) CellarCool cooling systems come with a liquid-temperature-measuring thermostat . The self-calibrating probe con- tains a sensor chip, which communicates back and forth with the thermostat . This results in a consistent temperature setting and accuracy .
