Description
MAINTENANCE OF OIL LEVEL
The compressor oil is circulating in the system together with the refrigerant. It is necessary to fill compressor with oil when replacing A/C system parts or when a large amount of refrigerant leakage is detected. It is important to always maintain oil level within the specified level. Otherwise, the following conditions may occur;
TYPE : Refer to HA "Oil".
Inspection
If a compressor is malfunctioning (internal noise, insufficient cooling), check the compressor oil.
1.COMPRESSOR OIL JUDGMENT
Judgement result 1>>Replace compressor only.
Judgement result 2>>Replace compressor and liquid tank.
CAUTION: If a large amount of refrigerant or oil leakage is detected, do not perform oil return operation.
1. Start the engine and set to the following conditions.
- Engine speed: Idling to 1,200 rpm
- A/C switch: ON
- Fan speed: Maximum speed set
- Intake door position: Recirculation
- Temperature setting: Full cold
Oil Adjusting Procedure for Components Replacement Except Compressor
Fill with oil for the amount that is calculated according to the following
conditions;
Example: oil amount to be added when replacing evaporator and liquid tank [m
(Imp fl oz.)] = 35 (1.2) + 5
(0.2) + α
1. Drain oil from removed compressor and measure oil amount.
2. Drain oil from a new compressor that is calculated according to the following conditions;
Amount to be drained (A) [m (Imp fl oz.)] = F − (D + S + R + α)
F : Oil amount that a new compressor contains [120 (4.2)]
D : Oil amount that is drained from removed compressor
S : Oil amount that remains inside of removed compressor [20 (0.7)]
R : Oil amount to be added according to components that are removed except compressor
α : Oil amount that is recycled together with refrigerant during recycle operation
CAUTION:
If oil amount that is drained from removed compressor is less than 60 m (2.1 Imp
fl oz.), perform
calculation by setting "D" as 40 m (1.4 Imp fl oz.).
Example: oil amount to be drained from a new compressor when replacing compressor and liquid tank [m (Imp fl oz.)] [D = 60 (2.1), α = 5 (0.2)] 120 (4.2) − [60 (2.1) + 20 (0.7) + 5 (0.2) + 5 (0.2)] = 30 (1.1)
3. Install compressor and check the operation.
