System Discharge Pressure
No adjustments are necessary to the discharge pressure. Once the pressurized oil is processed through the
ThermoJet Jet Mixer it enters the separation vessel where the air and removed water vapor is vented out of
the system. The return oil pump takes the processed oil from the separation tank and returns it to the
equipment reservoir or bulk oil supply tank being serviced. System pressure on the return oil circuit is
maintained by a check valve set at 50 PSIG (3.4 BAR).
Return oil pressure can be monitored by observing the System Discharge pressure gauge.
A pressure relief valve is installed on the in the return oil circuit before the check valve. The relief valve is
factory set at 270 PSIG (18.6 BAR). If the oil pressure will not reach 50 PSIG (3.4 BAR) the relief valve may
have operated and opened. See the trouble shooting section of this manual for additional information.
