PRECAUTIONS
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to an
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied lubricants have been used with the scale. If the scale controls
refrigerant flow electronically, the hose fitting must be 1/2²-16
ACME.
CALIBRATING ACR4 WEIGHT SCALE
Calibrate the scale every three months.
To calibrate the weight scale on the ACR4:
1. Press “Shift/Reset”and“Enter”at the same time.
2. Press “8787”.“A1” will be displayed.
3. Remove all weight from the scale.
4. Press “0”, then press “Enter”.“0.00” will be displayed and change to “A2”.
5. Place a known weight (dumbbell or similar weight), between 4.5 and 8.6 kg (10 and 19 lb.) on the center
of the weight scale.
6. Enter the known weight using four digits. (Example 10 lb. = 10.00, 10.5 lb. = 10.50)
7. Press “Enter”— the display returns to the vacuum mode.
8. Press“Shift/Reset”and“Enter”at the same time.
9. Press “6” — the known weight on the scale is displayed.
10. Remove the known weight from the scale. “0.00” will be displayed.
11. Press“Shift/Reset” to return the ACR4 to the program mode.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder’s top valve
when filling the cylinder with refrigerant. Also, the accuracy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.
Precautions for Leak Detection DyeEJS0062B
lThe A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet
(UV) lamp is required to illuminate the dye when inspecting for leaks.
lAlways wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.
lThe fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluo-
rescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector (J-
41995) to pin-point refrigerant leaks.
lFor your safety and your customer’s satisfaction, read and follow all manufacture’s operating instructions
and precautions prior to performing the work.

CHECKING PROCEDURE
To prevent inaccurate or false readings, make sure there is no refrigerant vapor, shop chemicals, or cigarette
smoke in the vicinity of the vehicle. Perform the leak test in calm area (low air/wind movement) so that the
leaking refrigerant is not dispersed.
1. Turn engine OFF.
2. Connect a suitable A/C manifold gauge set (SST) to the A/C service valves.
3. Check if the A/C refrigerant pressure is at least 345 kPa (3.45 bar, 3.52 kg/cm
2, 50 psi) above 16°C. If
less than specification, recover/evacuate and recharge the system with the specified amount of refriger-
ant.
NOTE:
At temperatures below 16°C, leaks may not be detected since the system may not reach 345 kPa (3.45
bar, 3.52 kg/cm
2,50psi).
4. Perform the leak test from the high-pressure side (compressor discharge a to evaporator inlet g) to the
low-pressure side (evaporator drain hose h to shaft seal l). Refer toMTC-120, "
Components". Perform a
leak check for the following areas carefully. Clean the component to be checked and move the leak
detected probe completely around the connection/component.
Compressor
Check the fitting of high- and low-pressure flexible hoses, relief valve and shaft seal.
Liquid tank
Check the refrigerant pressure sensor.
Service valves
Check all around the service valves. Ensure service valve caps are secured on the service valves (to pre-
vent leaks).
NOTE:
After removing A/C manifold gauge set from service valves, wipe any residue from valves to prevent any
false readings by leak detector.
Cooling unit (Evaporator)
With engine OFF, turn blower fan on “High” for at least 15 seconds to dissipate any refrigerant trace in the
cooling unit. Wait a minimum of 10 minutes accumulation time (refer to the manufacturer’s recommended
procedure for actual wait time) before inserting the leak detector probe into the drain hose.
Keep the probe inserted for at least 10 seconds. Use caution not to contaminate the probe tip with water
or dirt that may be in the drain hose.
5. If a leak detector detects a leak, verify at least once by blowing compressed air into area of suspected
leak, then repeat check as outlined above.
6. Do not stop when one leak is found. Continue to check for additional leaks at all system components.
If no leaks are found, perform steps 7 - 10.
7. Start engine.
8. Set the heater A/C control as follows;
a. A/C switch: ON
b. MODE control dial: VENT (Ventilation)
c. Intake door position: Recirculation
d. Max. cold temperature
e. Fan speed: High
9. Run engine at 1,500 rpm for at least 2 minutes.
10. Turn engine off and perform leak check again following steps 4 through 6 above.
Refrigerant leaks should be checked immediately after stopping
the engine. Begin with the leak detector at the compressor. The
pressure on the high-pressure side will gradually drop after
refrigerant circulation stops and pressure on the low-pressure
side will gradually rise, as shown in the graph. Some leaks are
more easily detected when pressure is high.
