2. Remove the insulation material from the suction line and remove the thermostatic expansion valve

(TEV) sensing bulb from the suction line.

3. Using a backup wrench, remove the liquid line from the bottom of the TEV.

4. Gently bend the liquid line away from the valve.

5. Unsolder the two remaining lines from the TEV.

6. Remove the expansion valve from the unit.

INSTALL

1. Prepare all fittings and tube ends to be soldered.

CAUTION

Do not contaminate the system when preparing refrigeration tubing for

soldering. Contamination may cause restrictions in the refrigeration

system. Failure to comply may result in damage to the equipment.

2. Solder the equalizer line and the evaporator line in the new expansion valve.

3. Connect the liquid line to the expansion valve.

4. Clean the suction line where the TEV sensing bulb was removed.

5. Install the TEV sensing bulb on the suction line.

6. Replace insulation around the TEV sensing bulb.

7. Evacuate the low side and test for leaks.

a. Connect the manifold gauge assembly.

b. Start the vacuum pump and evacuate the system to 500 microns.

NOTE

If the system will not come down to 500 microns, there may be a leak or

moisture in the system or in the evacuation and charging equipment

hoses. Find and repair the leak.

Close the valve at the evacuation pump, stop the vacuum pump, and observe the reading on the

vacuum gauge for 5 minutes. The pressure should not exceed 2000 microns.

d. If pressure does exceed 2000 microns, repeat step b. This time, if the pressure exceeds 2000

microns within 5 minutes, look for a leak in the system or in the evacuation and charging

equipment hoses. Find and repair the leak.
