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 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 1/2

″

ACME.

CALIBRATING ACR4 WEIGHT SCALE

Calibrate the scale every three months.
To calibrate the weight scale on the ACR4:

Press Shift/Reset and Enter at the same time.

Press 8787 . “A1 ” will be displayed.

Remove all weight from the scale.

Press 0 , then press Enter . “0.00 ” will be displayed and change to “A2 ”.

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.

Enter the known weight using four digits. (Example 10 lb = 10.00, 10.5 lb = 10.50)

Press Enter — the display returns to the vacuum mode.

Press Shift/Reset and Enter at the same time.

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.

PRECAUTIONS

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 Dye

EJS002XA

●

The 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.

●

Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.

●

The 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 to (J-
41995) pin-point refrigerant leaks.

●

For your safety and your Customer

′

s satisfaction, read and follow all manufacture

′

s operating instructions

and precautions prior to performing the work.

●

A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal
should only be repaired after confirming the leak with an electronic refrigerant leak detector (J-41995).

●

Always remove any remaining dye from the leak area after repairs are complete to avoid a misdiagnosis
during a future service.

●

Do not allow dye to come into contact with painted body panels or interior components. If dye is spilled,
clean immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period
of time cannot be removed.

●

Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).

●

Do not use more than one refrigerant dye bottle (1/4 ounce / 7.4 cc) per A/C system.

●

Leak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Do not use
HFC-134a (R-134a) leak detection dye in CFC-12 (R-12) A/C system or CFC-12 (R-12) leak detector dye
in HFC-134a (R-134a) A/C systems or A/C system damage may result.

●

The fluorescent properties of the dye will remain for over three (3) years unless a compressor malfunction
occurs.

IDENTIFICATION

NOTE:
Vehicles with factory installed fluorescent dye have a green label.
Vehicles without factory installed fluorescent dye have a blue label.

IDENTIFICATION LABEL FOR VEHICLE

Vehicles with factory installed fluorescent dye have this identification label on the front side of hood.

Wiring Diagrams and Trouble Diagnosis

EJS002XB

When you read wiring diagrams, refer to the followings:

●

GI-14, "How to Read Wiring Diagrams"

in GI section.

●

PG-5, "Wiring Diagram — POWER —/EXCEPT FOR F9Q ENGINE MODELS"

in PG section.

When you perform trouble diagnosis, refer to the followings:

●

GI-10, "How to Follow Trouble Diagnoses"

in GI section.

●

GI-24, "How to Perform Efficient Diagnosis for an Electrical Incident"

in GI section.

HFC-134a (R-134a) Service Tools and Equipment

EJS002XD

Never mix HFC-134a (R-134a) refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/or
its lubricant.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/lubri-
cant.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or lubricant) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
Adapters that convert one size fitting to another must never be used: refrigerant/lubricant contamination will
occur and compressor malfunction will result.
