Component CheckEFS005WL
ESP OFF SWITCH

Disconnect the ESP OFF switch connector. Check for continuity
between the terminal No. 1 and No. 2.

Disconnect the relay box connectors. Check for continuity, resis-
tance value, and insulation between any pair of terminals in the relay
box. 1 - 2 : Pressing the switch will make a continu-
ity, and releasing it will stop the continuity.

SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or automatic) near the end of the hoses
opposite the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
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 1/2″-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 . P r e s s Shift/Reset to return the ACR4 to the program mode.

LUBRICANT ADJUSTING PROCEDURE FOR COMPONENTS REPLACEMENT EXCEPT COM-
PRESSOR
After replacing any of the following major components, add the correct amount of lubricant to the system.
Amount of lubricant to be added
*1: If refrigerant leak is small, no addition of lubricant is needed.
LUBRICANT ADJUSTING PROCEDURE FOR COMPRESSOR REPLACEMENT
1. Before connecting ACR4 to vehicle, check ACR4 gauges. No refrigerant pressure should be displayed. If
NG, recover refrigerant from equipment lines.
2. Discharge refrigerant into the refrigerant recovery/recycling equipment. Measure lubricant discharged into
the recovery/recycling equipment.
3. Drain the lubricant from the old (removed) compressor into a graduated container and recover the amount
of lubricant drained.
4. Drain the lubricant from the new compressor into a separate, clean container.
5. Measure an amount of new lubricant installed equal to amount drained from old compressor. Add this
lubricant to new compressor through the suction port opening.
6. Measure an amount of new lubricant equal to the amount recovered during discharging. Add this lubricant
to new compressor through the suction port opening.
7. If the liquid tank also needs to be replaced, add another 5 m (0.2 Imp fl oz) of lubricant at this time.
Do not add this 5 m (0.2 Imp fl oz) of lubricant only when replaces the compressor.

Increase or decrease the set temperature.
FAN CONTROL DIAL
Automatically or Manually control the blower speed. Twenty-five speeds are available for manual control.
Shifting fan control dial to AUTO, compressor is turned ON automatically.
REAR WINDOW DEFOGGER SWITCH
When illumination is ON, rear window is defogged.
INTAKE SWITCH

When intake switch is ON, REC indicator turns ON, and air inlet is fixed to REC.

When press intake switch again, FRE indicator turns ON, and air inlet is fixed to FRE.

When intake switch is pressed for approximately 1.5 seconds or longer, REC and FRE indicators blink
twice. Then, automatic control mode is entered. Inlet status is displayed even during automatic control.

When DEF position or FRE indicator is turned ON, or when compressor is turned from ON to OFF, REC
switch is automatically turned OFF (fixed to FRE mode).
REC mode can be re-entered by pressing intake switch again. (Except DEF position)
A/C SWITCH
The compressor is ON or OFF.
(Pressing the A/C switch when the fan control dial is ON will turn off the A/C switch and compressor.)
