Tubing MUST be rated for full line pressure. The purpose of this tubing and valve is to
be a high point in the system for forcing out the air while filling the system with oil. The
tubing also allows oil that is lost to be easily directed to an open contained.
1. Connect tubing to the Low Side Oil Port.
2. Connect a
shut off valve to the end of the tubing.
Major Purge Process
1. Close the Pump Isolation Valve.
2. Open the
shut off valve .
3. Rotate the Pump to force oil through the instrument until no bubbles are noted at the
low port shut off valve .
4. Close the low port shut off valve .
5. Open the Oil Reservoir Valve and refill the Pump.
6. With the Oil Reserve Valve open, lift the weight loading table and hold it at the top
of travel.
7. Set the Oil Isolation Valve to isolate.
8. Open the low port
shut off valve .

trapped air may be removed by the following steps:
1. Close the low port shut off valve.
2. Set the
Oil Isolation Valve to Equalize.
3. Use the Pump to pressurize the system to full line pressure.
4. Close the
Pump Isolation Valve and refill the Pump.
5. Allow the system to remain pressurized about 2 hours to allow the gas to dissolve
into the oil.
6. Pressurize the Pump and open the Pump Isolation Valve . The system should still
be at full line pressure.
