Installation Tips and Guidelines
When brazing copper tubing to the service valves, use 95/5 solder and soldering
flux.
Do not use silver solder
because it requires higher heat that will damage the
service valves.
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 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.
Continue charging until system has sufficient refrigerant for proper operation.
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.
Do not leave unit unattended until the system has reached normal operating
conditions.
Make sure all access valve caps are in place and tight.
Make sure liquid and suction service valves are properly back-seated and tighten
valve packing if necessary.
Make sure the condenser fan cuts-in at 120 PSIG and cuts-out at 75 PSIG.
