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 DyeEJS006AR
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.

Operational CheckEJS006BH
The purpose of the operational check is to confirm that the system operates properly.
CHECKING MEMORY FUNCTION
1. Set the temperature to 32°C(90°F).
2. Turn blower control dial counterclockwise until system shuts
OFF.
3. Turn ignition switch OFF.
4. Turn ignition switch ON.
5. Press the AUTO switch.
6. Confirm that the set temperature remains at previous tempera-
ture.
7. Turn blower control dial counterclockwise until system shuts
OFF.
If NG, go to trouble diagnosis procedure forATC-104, "
Memory
Function".
If OK, continue with next check.
CHECKING BLOWER
1. Press the AUTO switch. Blower should operate on low speed.
The blower symbol should have one blade lit (on display).
2. Turn the blower control dial again, and continue checking blower
speed and blower symbol until all speeds are checked.
3. Leave blower on MAX speed.
If NG, go to trouble diagnosis procedure forAT C - 8 2 , "
DIAGNOSTIC
PROCEDURE FOR BLOWER MOTOR".
If OK, continue with next check.Conditions : Engine running and at normal operating temperature
