Re: about compressor oil

Re: about compressor oil
Would the "high pressure" be-
1) Oil Pressure?
Or
2) High Discharge Pressure?
If it is 1.
Then as Brian suggests you may of overfilled the Compressor with oil?
Or 2.
It is possible that you have accidentally allowed air into the refrigeration system.
Although in the past I have known rogue machines to have different oil pressures when using oils of slightly different Viscosities.
IE. The lower the number the thicker the oil and the higher the oil pressure.
This does not mean it is good though as the flow rates could be reduced when using thicker oils.
It is best to keep to the grades recommended by the customer.

Re: about compressor oil
Did you changed oil or only added some amount? What is oil full type name?
From what I know, Suniso 3,4,5GS are mineral oils and in system with R134A recommended oil is POE oil.
If original oil is POE and you added more than 5% of mineral oil you need to change oil until mineral oil percentage is less than 5%.

Re: about compressor oil
These are approved oils for your compressor:
Copeland Ultra 22CC
Mobil EAL ARCTIC 22CC
ICI (Virginia KMP) Emkarate RL 32CF
Thermal Zone 22CC
You added unapproved oil with viscosity different from original.
Suniso SL 68 is POE oil with viscosity of 79,1 at 40°C and these recommended oils have viscosity of 24 at 40°C.
Closest Suniso match is SL 22 but it is not approved oil from Copeland.
