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.
