INSTALLATION
CAUTION / NOTICE / HINT
NOTICE:
- Always use ND-OIL 12 as the compressor oil.
- The oil used for HFC-134a (R134a) systems (ND-OIL 8) does not work well in HFO-1234yf (R1234yf) systems. If the oil used for HFC-134a (R134a) systems (ND-OIL 8) is used in an HFO-1234yf (R1234yf) system, it will result in degradation of the refrigerant and deterioration of resin parts.
PROCEDURE
1. ADJUST COMPRESSOR OIL
(a) When replacing the compressor assembly with pulley with a new one, gradually discharge the inert gas (helium) from the service valve, and drain the following amount of oil before installation.
NOTICE:
- If a new compressor assembly with pulley is installed without removing the same amount of compressor oil as is remaining in the pipes, the amount of compressor oil will be excessive. This prevents heat exchange in the refrigerant cycle and will cause the air conditioning system to malfunction.
- A certain amount of compressor oil remains in the compressor assembly with pulley during circulation and the compressor may be damaged if the amount of compressor oil is more/less than this amount. Therefore, make sure to adjust the amount of compressor oil correctly.
- If the amount of compressor oil remaining in the removed compressor assembly with pulley is excessively low, check for compressor oil leaks.
- Make sure to use ND-OIL 12 or equivalent compressor oil.
|
(b) Remove the drain bolt (seal washer) from the removed compressor assembly with pulley. |
|
(c) Drain the compressor oil from the oil port of the removed compressor assembly with pulley as shown in the illustration.
NOTICE:
Make sure to drain the compressor oil from the oil port.

(d) Remove the drain bolt (seal washer) from a new compressor assembly with pulley. HINT: The drain bolt (seal washer) can be reused. |
|
(e) Drain the following amount of compressor oil from the oil port of the new compressor assembly with pulley as shown in the illustration.
Standard:
(The amount of oil in a new compressor assembly with pulley: 70 (+15) cc (2.37 (+0.51) fl.oz)) - (The amount of oil in the removed compressor assembly with pulley) = (The amount of oil to be removed from the new compressor assembly with pulley)
NOTICE:
- Make sure to drain the compressor oil from the oil port.
- Make sure to add the compressor oil from the oil port, not from the discharge or intake port.
- If a tool is used to add compressor oil to the new compressor assembly with pulley, make sure that it is free of foreign matter.
- If the amount of compressor oil remaining in the removed compressor assembly with pulley cannot be estimated because the compressor was damaged and oil was discharged due to a frontal collision, etc., install a new compressor assembly with pulley without removing any oil. If the cooler condenser assembly is also replaced, do not add the specified amount of compressor oil for cooler condenser assembly replacement (40 cc (1.35 fl.oz)).
