a. Performance Check
(1) Connect equipment as shown in figure 4, except do not connect hose (B10) to
fluid separator (B8).
Figure 4. 1000 to 5000 psi pneumatic gages (0.1 to 1 percent accuracy) - equipment setup.
(2) Open vent port on fluid separator.
(3) Operate hand pump until all the air is bled from hydraulic side of fluid
separator.
(4) With fluid separator full of oil, install plug-in vent port.
(5) Connect appropriate standard gage to pressure gage tester (A2).
(6) Fill pneumatic side of fluid separator with distilled water (B7), using squeeze
bottle (B15).
(7) Fill hose (B10) with distilled water and connect to fluid separator.
NOTE
In filling pneumatic side of fluid separator hose, connection,
and TI; it is important that the components be filled completely
and kept as full as possible during connection. Position
diaphragm to pneumatic side and hydraulic side several times
by manipulation of hand pump and reservoir valve on pressure
gage tester.
(8) Position fluid separator diaphragm to oil side by opening reservoir valve on
pressure gage tester and holding hose (B10) above fluid separator, creating a head
pressure. Refill hose as water falls.
(9) Fill TI with distilled water and connect to hose.
