Mc Quay compressor oil leak.

[jozef]

Hello guys,
I have a leak on McQuay compressor HSA263QS24YA.
Oil and refrigerant leaks through the screw on near the side cover, but I have no idea, what is the screw for.
Does anybody know, what is the screw for, and how to eventually seal it?
The screw is marked on the attached photo.
THanks in advance.

Don't know what it is for but depressurise the unit, remove the screw and apply suitable thread sealant and refit.
