Compressor Area Components
Power Cord Removal
The power cord enters the compressor area on the

To remove the power cord:
1. Pull unit from its installation position to access the
rear compressor area.
2. Using a phillips head screwdriver, extract the four
screws securing the compressor area shield to the
rear of the unit. Remove shield.
3. Using a 1/4” socket or wrench, extract the screw
securing the P-clamp to the compressor mounting
plate. (See Figure 5-23)
4. Using a 1/4” socket or wrench, extract the screw

The filter-drier is located in the compressor area on the
left side of the compressor. (See Figure 5-24)
To remove the filter-drier:
1. Pull unit from its installation position.
2. Extract the screws securing the fiber board cover to
the unit frame and remove from unit.
3. Recover refrigerant by using EPAapproved
recovery system.
4. Using a 3 cornered file, score a groove around
capillary tube as close to old filter-drier as possible.
Break capillary tube along score mark from
filter-drier.
5. Cut condenser outlet tube at filter-drier. Discard
filter-drier.
6. Thoroughly clean condenser outlet tube and
capillary tube.
7. Place inlet connection of filter-drier over condenser
tube approximately ¼” and solder.
8. Insert capillary tube input end into filter-drier outlet.
Do not allow tube to bottom against screen. Solder
carefully so that solder does not plug capillary tube.
9. Install process tube adapter to filter-drier.
10. Evacuate and charge system using the
