Removal and Installation for Expansion Valve
EJS000VH
1. Using the recycling and recovery equipment (for HFC-134a),
discharge the refrigerant.
2. Disconnect the low-pressure flexible hose and high-pressure
pipe from the evaporator.
CAUTION:
Cap or wrap the joint of the low-pressure flexible hose and
the high-pressure pipe with a suitable tool such as a vinyl
tape to avoid the entry of air.
3. Remove the expansion valve cover.
4. Remove the expansion valve.
Removal and Installation for Desiccant AssemblyEJS000VI
REMOVAL
1. Remove the condenser.
2. Clean the area around the snap ring. Remove any dirt or rust.
CAUTION:
Be sure to clean carefully.
3. Remove the snap ring from the lower side of liquid tank.
4. Remove the cap, filter and desiccant assembly.
INSTALLATION
1. Install the new desiccant, filter, cap, O-ring, and snap ring.
2. The work must be performed with clean hands. (Gloves may
not be worn.)
3. The desiccant, filter, cap, O-ring, and snap ring cannot be
reused.
4. When inserting the desiccant, be sure to insert it all the way in,
taking care not to allow any dirt to contact the surrounding area.
5. Do not install the filter backwards.
6. When inserting the cap, be certain to avoid having the O-ring
catch on something, fall out, or contact dirt
7. Apply lubricating oil to the cap O-ring, then insert all the way to
the end.
8. Check that there is no dust or dirt adhering to the snap ring installation groove.
9. The snap ring must be installed securely into the groove.
Checking for Refrigerant LeaksEJS000VJ
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C lubricant
leakage, damage and corrosion. A/C lubricant leakage may indicate an area of refrigerant leakage. Allow
extra inspection time in these areas when using either an electronic refrigerant leak detector or fluorescent
dye leak detector.
If dye is observed, confirm the leak with an electronic refrigerant leak detector. It is possible a prior leak was
repaired and not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electronic leak detector, move the probe along the suspected
leak area at 1 to 2 inches per second and no further than 1/4 inch from the component.Expansion valve mounting bolts
