1. Always install a suction strainer (Figure 7) into suction port (Figure 8) during repair and replacement of this type of compressor.

2. Strainers are available as separate spare parts.

3. A strainer is included in the valve plate/head gasket kit and with a new compressor.

4. With a new compressor also replace the receiver-dryer.


5. Always replace the expansion valve, if compressor had broken internal parts. Do not replace expansion valve if compressor is replaced for other reasons.

IMPORTANT:

1. When replacing compressors of this type due to seizing (broken internal parts), also replace the connected high pressure and suction lines (Figures 9 and 10).

NOTE: This prevents future compressor damage from particles lodged in old refrigerant lines that remain even after flushing.

2. Always replace expansion valve and receiver dryer when replacing a compressor that had broken internal parts.
