Flushing
General Procedures

1. WARNINGS:


Use extreme care and observe all safety precautions related to the
use of refrigerants. Due to refrigerant hazards, always wear safety
goggles and non-penetrable gloves when working on or flushing air
conditioning (A/C) systems. Failure to follow this instruction may result
in personal injury.


When flushing the A/C system, refer to the manufacturers
equipment instructions for additional information. Failure to do so may
result in system damage or personal injury.


The A/C refrigerant analyzer must be used before the recovery of
any vehicle's A/C refrigerant. Failure to do so puts shop bulk refrigerant
at risk of contamination. If the vehicle A/C refrigerant is contaminated,
refer the customer to return to the repair facility that performed the last
A/C repair. If the customer wishes to pay the additional cost, use the
A/C recovery equipment that is designated for recovering contaminated
A/C refrigerant. All contaminated A/C refrigerant must be disposed of as
hazardous waste. For additional information, refer to the manufacturers
equipment instructions. Failure to follow this instruction may result in
personal injury.


Prior to using the A/C flushing equipment for the first time, follow
the operating instructions. Failure to follow this instruction may result in
personal injury.


CAUTION: Prior to flushing, remove and discard the desiccant sack.
Depending on the equipment used, other A/C components may have to
be removed prior to flushing. For additional information, refer to the
manufacturers equipment instructions before flushing the A/C system.
Recover the refrigerant.
For additional information, refer to Air conditioning (A/C) System Recovery, Evacuation and Charging in this section.
2. Remove the desiccant sack.
For additional information, refer to Section 412-03 Air Conditioning.
3. Flush the system. For additional information, refer to the manufacturers
equipment instructions.

4. Install new refrigerant lines if blocked with debris.

5. Install a new desiccant sack.
For additional information, refer to Section 412-03 Air Conditioning.
6. Add the required amount of oil to the A/C system depending on the
repair procedure.
For additional information, refer to Refrigerant Oil Adding in this section.
7. Evacuate and charge the A/C system.
For additional information, refer to Air conditioning (A/C) System Recovery, Evacuation and Charging in this section.
8. Carry out fluorescent dye leak detection test.

Climate Control System - General Information - Electronic Leak Detection
General Procedures


1. WARNING: Good ventilation is necessary in the area where A/C leak
testing is to be carried out. If the surrounding air is contaminated with
refrigerant gas, the leak detector will indicate this gas all the time.
Odors from other chemicals such as antifreeze, diesel fuel, disc brake
cleaner, or other cleaning solvents can cause the same problem. A fan,
even in a well ventilated area, is very helpful in removing small traces of
contamination from the air that might affect the leak detector. Failure to
follow this instruction may result in personal injury.

Attach an R-134a manifold gauge set or use a UL-approved
recovery/recycling device such as an R-134a A/C refrigerant center (which
meets SAE Standard J 1991). For additional information, refer to the
manufacturers equipment instructions.
Both gauges should indicate 413-551 kPa (60-80 psi) at 24°C
(75°F) with the engine off.
If little or no pressure is indicated, carry out the air conditioning
(A/C) system recovery, evacuation and charging procedure.
For additional information, refer to Air Conditioning (AC) System Recovery, Evacuation and Charging in this section.
2. Use an R134-a Automatic calibration halogen leak detector to leak test
the refrigerant system. For additional information, refer to the
manufacturers equipment instructions.

3. If a leak is found, carry out the air conditioning (A/C) system recovery
procedure.
For additional information, refer to Air Conditioning (AC) System Recovery, Evacuation and Charging in this section.

Climate Control System - General Information - Fluorescent Dye Leak Detection
General Procedures


1. WARNING: Eye protection glasses supplied with the ultraviolet (UV)
lamp should be used to protect eyesight from harm.


NOTE: The air conditioning (A/C) system has an R-134a leak trace
dye wafer incorporated into the desiccant bag. The exact location of
leaks can be pinpointed by the bright yellow/green glow of the tracer
dye. Since more than one leak may exist, always inspect each
component. If it is necessary to add dye (due to a severe leakage for
example) use proprietary tracer dye injection equipment.
Check for leaks using ultraviolet (UV) lamp.

2. Check all components, fittings and lines of the A/C system.

3. Carry out the repair. For additional information, refer to Section 412-03 Air Conditioning.
4. After the leak is repaired, remove any traces of leak trace dye with a
general purpose oil solvent.

5. Check the A/C system for correct operation.

6. Verify the repair by operating the system for a short time and inspecting
with the (UV) lamp.

General Procedures

1. Check for leaks using ultraviolet (UV) Lamp.
For additional information, refer to Flourescent Dye Leak Detection in this section.

2. NOTES:


Any time a hose or component connection leak is observed, the
component and fitting must be separated, cleaned and a new O-ring
fitted and lubricated with air conditioning compressor oil.
For additional information, refer to Specifications in this section.

When separating A/C joints, cap the open connections
immediately. Do not leave open to atmosphere.

O-ring seal surfaces must be free of dirt, lint, burrs and scratches. The
O-ring and connector should be lubricated with air conditioning
compressor oil.
For additional information, refer to Specifications in this section.
