 Confirm that the compressor, condenser fan, and evaporator fan(s) are
energized. Allow the system to balance for 30 minutes, then record all readings
on the Data Sheet and submit to CellarPro for warranty activation review.
 Observe that the condensing unit turns on when the “snowflake” icon on the
temperature display is lit solid (not blinking), and turns off when the “snowflake”
icon turns off. It may be necessary to temporarily raise the set point to force
the unit to cycle off. If the condensing unit does not cycle on/off in conjunction
with the “snowflake” icon, please contact the factory for assistance.
Installation Tips and Guidelines
 Make sure all electrical connections are secure.
 Inspect Evaporator and Condensing unit fans to confirm airflow. There shouldn’t
be any excessive vibration, noise or obstructions to airflow.
 Observe system pressures and temperatures during charging and initial
operation and keep note of them as they will be required for the Service and
Support Data Sheet which initiates the warranty.
 Do not overcharge or use refrigerant with additives.
 Remember that bubbles in a sight glass may be caused by a restriction as well
as a shortage of refrigerant. A properly charged system may still have small
bubbles visible in the sight glass, so use actual superheat and subcooling
readings to charge the system.
 Do not leave unit unattended until the system has reached normal operating
conditions, and the system has been observed properly cycling on/off to the
desired set point and differential.
 Make sure all access valve caps are in place and tight.
 If your system is equipped with a compressor heater, make sure this is wired to
be energized even when the system is idle.
 If the system has been sitting idle without the compressor heater energized for
more than 24 hours, or starting up the system in a cold ambient, it is critical to
warm the bottom shell of the compressor above the ambient temperature for 30
minutes before running the system to drive excess refrigerant out of the
compressor oil.
