Daikin Air Cooled Chiller Compressor Problems

[SteveCass]

Hi All,

Looking after a Daikin EUWAD500 chiller with 2 Mcquay HSA3221QY11YB Screw compressors.

One of them is coming up with 'high oil diff pressure' we have shut it down and will be opening it up to have a look at the oil filter, but has anyone seen this before? Checked the pressure and there is a >2bar differential, hence the look at the filter.

Also, has anyone got a exploded parts diagram for any of these types of compressors?

Any help will be appreciated,
