Residential Air Conditioners and Heat Pumps Using R-22 and Puron® Refrigerant: Application Guideline and Service Manual

Electrical Controls and Wiring

1. Disconnect power to both outdoor and indoor units.
2. Check all electrical connections for tightness. Tighten all screws on
electrical connections. If any connections appear to be burned or
smoky, disassemble the connection, clean all parts and stripped
wires, and reassemble. Use a new connector if old one is burned or
corroded, and crimp tightly.
3. Reconnect electrical power to indoor and outdoor units and observe
unit through 1 complete operating cycle.
4. If there are any discrepancies in operating cycle, troubleshoot to
find cause and correct.

Refrigerant Circuit

1. Check refrigerant charge using the superheat method, and if low on
charge, check unit for leaks using an electronic leak detector.
2. If any leaks are found, remove and reclaim or isolate charge
(pumpdown) if applicable. Make necessary repairs.
3. Evacuate, recharge, and observe unit through 1 complete operating
cycle.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

1. Check that unit operational noise is not excessive due to vibration
of component, tubing, panels, etc. If present, isolate problem and
correct.
2. Check to be sure caps are installed on service valves and are tight.
3. Check to be sure tools, loose parts, and debris are removed from
