12. Rotate the pump spindle fully clockwise to purge any air from the pump housing,
then rotate the spindle fully counterclockwise. Close the Oil Reservoir Valve.
13. Open the Pump Isolation Valve and rotate the pump spindle clockwise. This will
force the DOS oil through the line connected to the rear of the main instrument.
Continue pumping until DOS oil comes out of the loose fitting at the High Side Oil
Port. Once DOS oil is coming out of this fitting then tighten the fitting.
Once the system is sealed by tightening all fittings, the Oil Isolation Valve must be in
Equalize position. While the Oil Isolation Valve is in Equalize mode, turning the
pump spindle generates line pressures. While the Oil Isolation Valve is in Isolation
mode, turning the pump spindle will generate Delta pressures.
Note
If the pump spindle runs out of travel before the DOS oil comes out of the
line, repeat steps 12, 13, and 14.
14. Once the air is purged from the high side oil line, close the Pump Isolation Valve and
open the Oil Reservoir Valve. This prevents pressure building in the pump assembly
when not in use.
Note
When the system is free of air and closed, and the Oil Isolation Valve is in
Equalize mode, a one-half turn of the pump handle will generate system
line pressure.
Gas Mode Setup
The setup for gas mode operation does require the entire oil mode setup to be completed
as detailed in the Mechanical Setup section. A regulated gas supply needs to be
connected as shown.
