The self-contained models are shipped from the factory with a completely operational 404A refrigeration
system and require no modifications or adjustments upon installation. Case must be installed as per the
installation section of this manual to provide proper condensing air cooling.
The dual pressure control is used as a safety device and is factory set. The pressure control works on a
differential. The low-pressure side is a safety to protect the compressor in the case of refrigerant loss. The
high-pressure side is a safety to protect from system failure causing too high of system pressure.
The high side of the pressure control is factory set to 400psi and is not adjustable. Low side setting
for the R404a cases are set at 40psi differential for the cutout and 60psi for the cut-in.
Note: The condenser fan runs continuously.
This unit also has a defrost timer that will shut the compressor off a set number of times per day to insure a
full defrost occurs. The compressor will remain off until the either the off time is reached or until the
temperature sensor on the coil reaches a set temperature, which ever happens first.
