Before installing the new Compressor, check the amount of Compressor oil necessary for the system. Follow the procedure described below:
|A - B = Oil amount to remove from new Compressor|
|A (new Compressor)|
B (remaining in old Compressor)
Oil amount to remove from new Compressor
|= 120 cc (4.22 fl oz)|
= 50 cc (1.76 fl oz)
= 70 cc (2.46 fl oz)
|Compressor Type||Refrigerant Type Hfc134a||Oil Type|
|10PA, 7SB, 6SE, SC, 6CA series||HFC134a (R-134a)||DENSO-oil 8 Or equivalent|
|CFC12 (R-12)||DENSO-oil 6 Or equivalent|
|TV series||HFC134a (r-134a)||DENSO-oil 9 Or equivalent|
After replacing the DENSO Compressor, always follow the run-in procedure to avoid possible compressor damage.
|RUN IN PROCEDURE|
You can use the following oil replacement calculation when converting (retrofitting) a CFC12 system to HFC134a.
All 10P type DENSO Compressors use ND-oil 8 for HFC134a. All TV type compressors use ND-oil 9 for HFC134a. The amount of oil to be replaced can be calculated as follows: Specified oil amount for CFC12 x 1.2 = specified retrofit amount for HFC134a.
When replacing a compressor it is necessary to follow the DENSO procedure for oil replacement. Always make sure you use the specified oil of the DENSO Compressor. DENSO offers different grades of Compressor oil with two size options:
ND-oil 8 is used in the following DENSO Compressor types: 5SL, 6SE12, 6SEU12, 6CA17, 7SBU16, 7SEU16, 10P15, 10PA15, 10P17, 10S17, 10PA17, 10PA20, SCS06-5SL, SCSB06, SCS8, SC08
ND-oil 9 is used in the following DENSO Compressor types: TV12SC, TV14EC
