Replacing Drier

NOTE: A new drier must be installed whenever any

system component is replaced, or whenever the

system is opened.

The replacement drier is sealed at both ends to prevent

entrance of moisture. Do not break these seals until all

preparations for the installation have been completed.

1. Disconnect line cord from electrical outlet.

2. Clean the process tube using steel wool or fine emery

cloth.

3. Install service valve as close as possible to the tip of

the process tube, for easy pinch-off after recharging

the system.

4. Connect a hose to the service valve and capture the

charge.

NOTE: Effective July 1, 1992, before opening any

refrigeration system it is the responsibility of the

service technician to capture the refrigerant for

safe disposal.

5. Remove all paint and scale from the capillary tube for

a distance of approximately three inches from the

original joint, (use steel wool or emery cloth).

6. Cut the capillary tube approximately one inch from

the old joint. Verify the cut is uniform around the

tubing, then break it with the fingers.

Cutting Capillary Tube

7. Cut the drier from condenser outlet and thoroughly

clean the end of the tube.

8. Make an offset 1/2 inch (13 mm) from the end of the

capillary tube to prevent its penetrating too far into

drier tubing. When forming the offset, use a radius

large enough so the inside diameter of the tubing is

not reduced.

9. Cut the inlet tube on the new drier.

10.Snap off the scored end of replacement drier with

your fingers.

11. Install new drier and solder all joints. Use sil-fos on all

copper to copper joints. On copper to steel joints,

silver solder with proper flux must be used. Excess

flux must be wiped off after soldering.

12.Visually check all soldered joints, evacuate and

recharge the system.

13.Test run the unit to verify proper operation.

14.Pinch process tube and cut off the service valve.

Solder the joint and test for leaks.

Replacing Compressor

Replacement compressors are charged with the correct

amount of oil and contain a holding charge of either dry

nitrogen or a refrigerant.

The replacement compressor will be similar to the type of

compressor originally used and may or may not have an

oil cooler. If the sealed system does not use the oil

cooler, do not disturb the oil cooler plugs. Simply

disregard the oil cooler.

The holding charge assures compressor is dry. A

compressor which shows no evidence of internal

pressure when cutting the line or pulling the plugs,

should be returned for replacement.

When replacing a compressor, cut as close to the

soldered joints as possible. If tubes are not long enough,

it may be necessary to unsolder the joints to allow

connections to the replacement compressor.

When replacing compressor, proceed as follows:

1. Disconnect line cord from electrical outlet.

2. Install a service valve on the process tube.

3. Connect a hose to the service valve and capture the

charge.

NOTE: Effective July 1, 1992, before opening any

refrigeration system it is the responsibility of the

service technician to capture the refrigerant for

safe disposal.

4. Clean the tubing approximately three inches (76 mm)

at the point of intended cut. Before cutting the tube,

verify it will be long enough to reconnect to the

replacement compressor. If not, unsolder the joints.
