Low-Temperature Kit for Select SmartRack® In-Row Precision Cooling Units When the outdoor ambient temperature is lower than the minimum design temperature of the air conditioning unit, a low-temperature kit must be installed to ensure normal start-up and operation of the air conditioning unit. The SRCOOLDXRWLTKIT is an integral box featuring four copper pipes on the outside that connect with your precision cooler's indoor and outdoor units. The fully assembled and self-contained kit allows operation when outdoor temperatures fall below -4°F (-15°C) and down to -40°F (-40°C). It is compatible with SRCOOLDXRW12 and SRCOOLDXRW25 In-Row Precision Coolers.
