Re: Bitzer oil problem
The Bitzer screws I've seen had an oil pressure control but not an oil level.
It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Re: Bitzer oil problem
I think it's a oil level switch.
Harry, have you checked the superheat in cooling, both at the expansion valve & compressor suction ??
Are you familiar with how to do this ??

Re: Bitzer oil problem
Here you can see in bottom the oil level switch.
Yes gingerair, i know how to do this,but the compressor works only for one minute,then it stops.

Re: Bitzer oil problem
Makes the most sense to me.... you need to obtain more information in the safest possible way and that means... add the oil and run the system and see the behaviour.... does the oil run out again ? does it trip on the oil pressure switch ?if it does .. at what temperature does it happen ? ...

Re: Bitzer oil problem
I think Andy might be on the money. If the oil comes back on cooling you may need to check condenser design for cooling and or put a timer set to bring on the cooling mode occasionaly to return the oil.

Re: Bitzer oil problem
Hello to everybody.I went to the chiller today.I put oil in the system about 20lt.[The compressor takes 22lt].
The oil level switch was reset,but i cannot see the oil level in the sight glass.I was watching it during the filling.What could had happened?
I started the system for about twenty minutes,still no level in sight glass,and have the
below measurements in heating:
HP=260PSI
LP=42,4PSI
SUPERHEAT AT SUCTION VANE=9C
SUBCOOLING AT FILTER DRIER=8.7C
ENTERING WATER=37.7C
LEAVING WATER=39.7C
DISCHARGE TEMP=80C
OUTDOOR TEMP=10C
I checked the oil return from the accumulator.No restriction or oil there.
