Component Tests and General Diagnostics

The oil used to lubricate the compressor circulates in the system while the compressor is operating. Whenever replacing any component of the system or when a large amount of gas leakage occurs, add oil to maintain the original total amount of oil.
Total amount of oil in the system : 207-230 cc (12.6-14 fl.oz)
210-230 cc (12.8-14 fl.oz)

HANDLING OF OIL
1. The oil should be free from moisture, dust, metal filings, etc.
2. Do not mix oils.
3. The moisture content in the oil increases when exposed to the air for prolonged periods.
After use, seal the container immediately.

ADDING OIL FOR REPLACEMENT OF COMPONENT PARTS
When replacing the system's component parts, be sure to add the following amount of oil to the parts being replaced.

Component parts to be replaced Amount of oil cc (US fl oz, Imp fl oz)
Evaporator core 50 (1.6, 1.8)
Condenser 30 (1.0, 1.1)
Accumulator 80 (2.6, 2.9)

HOSE AND PIPE CHECK
Check the heater and air conditioner hoses and lines for damage due to interference with adjoining parts. If damage is major, replace the affected parts.


NOTE: Carefully check the hoses and lines, especially those located close to moving parts or sharp panel edges.


CHECKING REFRIGERANT LEAKS
Do a leak test with an electronic leak detector whenever leakage or something strange is suspected and when carrying out service operations which are accompanied with disassembly or loosening or connection fittings.




Electric Leak Detector
The leak detector is a delicate device that detects small amounts of halogen.


NOTE: In order to use the device properly, read the manuals supplied by the manufacturer to perform the specified maintenance and inspections.


If a gas leak is detected, proceed as follows:
1. Check the torque on the connection fitting and, if too loose, lighten to the proper torque. Check for gas leakage with a leak detector.
2. If leakage continues even after the fitting has been retightened, discharge the refrigerant from the system, disconnect the fittings, and check its seating face for damage. Always re place, even if the damage is slight.
3. Check compressor oil and add oil if required.
4. Charge the system and recheck for gas leaks. If no leaks are found, evacuate and charge the system.
