valve

Release the limiter spring.

Closed inlet valves to all bearings.

Start JOP I and adjust the JOP header pressure to 150 kg/cm2.

Install the Dial gauges with Magnetic Base 0-10 mm for measuring

each journal lift.

Adjust the lift of rotor in each bearing (between 0.08 to 0.1 mm)

with dial gauge.

Carry out hand barring

Ensure that the rotor is free with hand barring.

chamber exhauster fan is running.

Ensure that there is vacuum in the seal oil tank.

Ensure that seal oil filter elements are installed in the filters.

Ensure that oil is taken in seal oil system and there is normal level

in SOT and IOT.

Run Seal Oil Pump I and ensure proper operation of CPR (Constant

Pressure Regulator) and DPR-I (Differential Pressure Regulator).

Ensure proper operation of the second DPR-II and ensure change

over of CPR.
