Introducing the Cold Weather Start Kit by WhisperKOOL. This kit was
designed exclusively for our split-systems where the condensing unit
will be installed in extremely cold environments. Our split systems are
designed to be adaptable to almost any install, as the condensing unit
can be located in a variety of locations such as a mechanical room,
basement, back yard, or even a rooftop. Our split systems were designed
to operate with the condensing unit exposed to temperatures between 20° F
and 110° F. However, there are some areas in the country that may drop
below 20° F. Due to these conditions WhisperKOOL designed the Cold
Weather Start Kit.
So, when the outside temperatures drop, the
pressure in the system drops as well. This presents a challenge because
our systems operate using a pump down cycle and a low pressure switch to
turn the compressor on and off. However, when the temperature drops
below 20° F the pressure in the system is too low to start the
compressor. The use of an electronic bypass is needed to start the
compressor and temperature controlled heaters installed on the receiver
are needed to raise the pressure in the system to optimal levels.
The Cold Weather Start Kit will bypass the low pressure switch on
startup and keep the pressure in the system high enough to operate
correctly for environments as cold as -15° F.
It is important
that the cooling system stays operational during cold weather
conditions, as heating the house using the central HVAC system will
indirectly increase the temperature of the wine cellar. This kit will
ensure that the cooling system will continue to operate efficiently in
cold weather environments to maintain an optimal wine storage
The Cold Weather Start Kit can be ordered as an
upgrade on a new unit from the factory, or as an option for a unit
already installed in the field, which comes with instructions to guide a
technician through the install.
