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.

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.

THERMOMETER AND HYGROMETER

An etched stem-type thermometer and a hygrometer can be used to
check the air conditioning system performance. A hygrometer is
used because the air conditioning performance depends on the
humidity.

Wiring Diagrams and Trouble Diagnosis

EJS001ZT

When you read wiring diagrams, refer to the following:

●

Refer to 

GI-13, "How to Read Wiring Diagrams"

 .

●

Refer to 

PG-9, "POWER SUPPLY ROUTING"

  .

When you perform trouble diagnosis, refer to the following:

●

Refer to 

GI-9, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES"

 .

●

Refer to 

GI-25, "How to Perform Efficient Diagnosis for an Electrical Incident"

PREPARATION

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

EJS001ZV

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 or refrigerant/lubricant contamination will
occur and compressor failure will result.
