PREPARATION
HFC-134a (R-134a) Servic e Tool and Equipment INFOID:0000000004307051
Never mix HFC-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.

OIL
Maintenance of Oil Qu antity in Compressor INFOID:0000000004307056
The oil in the compressor circulates through the system with the refrigerant. Add oil to compressor when
replacing any component or after a lar ge refrigerant leakage occurred. It is important to maintain the specified
amount.
If oil quantity is not maintained properly , the following malfunctions may result:
• Lack of oil: May lead to a seized compressor.
• Excessive oil: Inadequate cooling (thermal exchange interference)
OIL
OIL ADJUSTING PROCEDURE FOR COMPONENTS REPLACEMENT EXCEPT COMPRESSOR After replacing any of the following major component s, add the correct amount of oil to the system.
Amount Of Oil To Be Added
*1: If refrigerant leak is small, no addition of oil is needed.
OIL ADJUSTING PROCEDURE FOR COMPRESSOR REPLACEMENT TYPE 1 Compressor (CR-10) : NISSAN A/C System Oil Type R
TYPE 2 Compressor (CSV511) : NI SSAN A/C System Oil Type S
Part replaced Oil to be added to system

Removal and Installation INFOID:0000000004307078
NOTE:
Only MR18DE - TYPE 2 systems are equipped with a thermo control amplifier.
REMOVAL 1. Remove evaporator. Refer to MTC-85, " Removal and Installation of Evaporator " .
CAUTION:
Cap or wrap the joint of the pipe with suitable ma terial such as vinyl tape to avoid the entry of air.
2. Mark the mounting position of the thermo control amp. and then remove thermo control amp. (1) from evaporator (2).
INSTALLATION Installation is in the reverse order of removal.
CAUTION:
• Replace O-rings for A/C piping with new on es, and apply compressor oil when installing.
• Install the thermo control amp. at the mark made during removal of the thermo control amp.
• When recharging refrigerant, check for leaks.
