4. Replace the O-rings.
-
O-rings cannot be reused. Always replace with new ones.
-
Be sure to apply specified compressor oil to the new O-rings.
5. Retighten the refrigerant line fitting to the specified torque.
-
Use two wrenches to prevent twisting and damage to the line.
6. Evacuate, charge and retest the system.
Leaks in the Hose
If the compressor inlet or outlet hose is leaking, the entire hose must be replaced. Refrigerant hose must not be cut or spliced for repair.
1. Locate the leak.
2. Discharge and recover the refrigerant.
3. Remove the hose assembly.
-
Cap the open connections at once.
4. Connect the new hose assembly.
-
Use two wrenches to prevent twisting or damage to the hose fitting.
-
Tighten the hose fitting to the specified torque.
5. Evacuate, charge and test the system.
Compressor Leaks
If leaks are located around the compressor shaft seal or shell, replace or repair the compressor.
Recovery, Recycling, Evacuation and Charging Handling HFC-134a:
Air conditioning systems contain HFC-134a.
This is a chemical mixture which requires special handling procedures to avoid personal injury.
-
Always wear safety goggles and protective gloves.
-
Always work in a well-ventilated area. Do not weld or steam clean on or near any vehicle- installed air conditioning lines or components.
-
If HFC-134a should come in contact with any part of the body, flush the exposed area with cold water and immediately seek medical help.
-
If it is necessary to transport or carry any container of HFC-134a in a vehicle, do not carry it in the passenger compartment.
-
If it is necessary to fill a small HFC-134a container from a large one, never fill the container completely. Space should always be allowed above
the liquid for expansion.
-
HFC-134a and R-12 should never be mixed as their compositions are not the same.
-
HFC-134a PAG oil tends to absorb moisture more quickly than R-12 mineral oil and, therefore, should be handled more carefully.
-
Keep HFC-134a containers stored below 40 °C (100 °F).
WARNING:
-
SHOULD HFC-134a CONTACT YOUR EYE(S), CONSULT A DOCTOR IMMEDIATELY.
-
DO NOT RUB THE AFFECTED EYE(S). INSTEAD, SPLASH QUANTITIES OF FRESH COLD WATER OVER THE AFFECTED
AREA TO GRADUALLY RAISE THE TEMPERATURE OF THE REFRIGERANT ABOVE THE FREEZING POINT.
-
OBTAIN PROPER MEDICAL TREATMENT AS SOON AS POSSIBLE. SHOULD THE HFC-134a TOUCH THE SKIN, THE
INJURY MUST BE TREATED THE SAME AS SKIN WHICH HAS BEEN FROSTBITTEN OR FROZEN.
Refrigerant Recovery
The refrigerant must be discharged and recovered by using the J-39500 (ACR4: HFC-134a Refrigerant Recovery/Recycling/Recharging/System) or
equivalent before removing or mounting air conditioning pants.
