PRECAUTIONS

HA-13

< PRECAUTION >

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. If an improper

connection is attempted, discharging and contamination may occur.

REFRIGERANT WEIGHT SCALE

Verify that no refrigerant other than HFC134a (R-134a) and specified

oils have been used with the scale. If the scale controls refrigerant

flow electronically, the hose fitting must be 1/2”-16 ACME.

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.

The actual shapes of Kent-Moore tools may differ from those of special service tools illustrated here.

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

INFOID:0000000007356302

Never mix HFC-134a (R-134a) refrigerant and/or its specified oil with CFC-12 (R-12) refrigerant and/or its oil.

Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/oil.

Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles

refrigerant and/or oil) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid mixed

use of the refrigerants/oil.

Adapters that convert one size fitting to another must never be used refrigerant/oil contamination will occur

and compressor failure will result.

CAUTION:

The new and former refrigerant connections use different O-ring configurations. Do not confuse O-

rings since they are not interchangeable. If a wrong O-ring is installed, refrigerant will leak at or

around the connection.
