Refrigerant Circuit O-Rings
- Always use O-rings only once, replace.
- Coat O-ring seals with refrigerant oil before inserting.
- Make sure O-rings are seated properly on pipe or in groove.
- Perform the work under clean conditions (even the smallest deposit such as a hair may cause a leak).
NOTE:
Install only O-rings that are resistant to refrigerant R134a and corresponding refrigerant oil. The O-rings are color-coded to avoid mistakes (currently "red", "light purple" and "dark purple").
The O-ring dimensions -a- and -b- are different depending on installation location.
In addition to the color-coded O-ring seals, use is also made at the factory of black O-ring seals for certain connections.
