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.
