CHECK REFRIGERANT LEAKAGE USING FLUORESCENT LEAK DETECTION DYE
1. Install a fender cover (1).
2. Wear UV safety goggles (2) provided with refrigerant dye leak detection kit (J-43926).
3. Connect power cable (4) of UV lamp (6) to positive and negative terminals of the battery (3).
4. Press UV lamp switch (5) and check A/C system for refrigerant leakage. (Where refrigerant leakage occurs, fluorescent leak detection dye appears
in green color.)
WARNING:
Never look directly into UV lamp light source.
NOTE:
-
For continuous operating time of UV lamp, follow the manufacturer operating instructions.
-
Illuminate piping joints from different angles using UV lamp and check that there is no leakage.
-
Use a mirror in area that is difficult to see to check refrigerant leakage.
-
Refrigerant leakage from evaporator can be detected by soaking cotton swab or a similar material with drain hose water and illuminating it using
UV lamp.
-
Dust, dirt, and packing materials adhesive used for condenser, evaporator, and other locations may fluoresce. Be careful not to mis-identify
leakage.
5. Repair or replace parts where refrigerant leakage occurs and wipe off fluorescent leak detection dye.
NOTE:
Completely wipe off fluorescent leak detection dye from gaps between parts, screw threads, and others using a cotton swab or similar materials.
6. Use a UV lamp to check that no fluorescent leak detection dye remains after finishing work.
WARNING:
Never look directly into UV lamp light source.
NOTE:
-
For continuous operating time of UV lamp, follow the manufacturer operating instructions.
-
Dust, dirt, and packing materials adhesive used for condenser, evaporator, and other locations may fluoresce. Be careful not to mis-identify
leakage.
CHECK REFRIGERANT LEAKAGE USING ELECTRICAL LEAK DETECTOR
WARNING:
Never check refrigerant leakage while the engine is running.
CAUTION:
Be careful of the following items so that inaccurate checks or mis-identifications are avoided.
