- Always use O-rings only once, replace.

- 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-ring seals 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-rings, use is also made at the factory of black O-ring seals for certain connections.
