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 171 PSIG and cuts-out at 104.5 PSIG.
