The oil contained inside the vacuum pump is not compatible with the

specified oil for HFC-134a (R-134a) A/C systems. The vent side of

the vacuum pump is exposed to atmospheric pressure so the vac-

uum pump oil may migrate out of the pump into the service hose.

This is possible when the pump is switched off after evacuation (vac-

uuming) and hose is connected to it.

To prevent this migration, use a manual valve situated near the

hose-to-pump connection, as follows.

• Usually vacuum pumps have a manual isolator valve as part of the

pump. Close this valve to isolate the service hose from the pump.

• For pumps without an isolator, use a hose equipped with a manual

shut-off valve near the pump end. Close the valve to isolate the

hose from the pump.

• If the hose has an automatic shut off valve, disconnect the hose

from the pump: as long as the hose is connected, the valve is open

and lubricating oil may migrate.

Some one-way valves open when vacuum is applied and close

under a no vacuum condition. Such valves may restrict the pump's

ability to pull a deep vacuum and are not recommended.

MANIFOLD GAUGE SET

Be certain that the gauge face indicates HFC-134a (R-134a or

134a). Make sure the gauge set has 1/2

″-16 ACME threaded con-

nections for service hoses. Confirm the set has been used only with

refrigerant HFC-134a (R-134a) along with specified oil.

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.

< PRECAUTION >

PRECAUTIONS

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.

Special Service Tool

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:0000000006163097

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

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.
