HAC-200

< PRECAUTION >

[AUTO AIR CONDITIONER (W/O NAVI)]

PRECAUTIONS

- Do not allow A/C oil to come in contact with styrofoam parts. Damage may result.

CONTAMINATED REFRIGERANT

If a refrigerant other than pure HFC-134a (R-134a) is identified in a vehicle, your options are:
• Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant into

the atmosphere.

• Explain that recovery of the contaminated refrigerant could damage your service equipment and refrigerant

supply.

• Suggest the customer return the vehicle to the location of previous service where the contamination may

have occurred.

• If you choose to perform the repair, recover the refrigerant using only dedicated equipment and contain-

ers. Do not recover contaminated refrigerant into your existing service equipment. If your facility does
not have dedicated recovery equipment, you may contact a local refrigerant product retailer for available ser-
vice. This refrigerant must be disposed of in accordance with all federal and local regulations. In addition,
replacement of all refrigerant system components on the vehicle is recommended.

• If the vehicle is within the warranty period, the air conditioner warranty is void. Please contact NISSAN Cus-

tomer Affairs for further assistance.

Precaution for Service Equipment

INFOID:0000000001547462

MANIFOLD GAUGE SET

Be certain that the gauge face indicates R-134a or 134a. Make sure
the gauge set has 1/2

″

-16 ACME threaded connections 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.

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.
