gaskets to the housing
interface
Reinstall the four way mani-
fold, making sure to line up the
square port on the housing with
the square port on the four way
manifold
Replace any gaskets / O-rings

29 We highly recommend pres-
sure testing your pump for
leaks before putting it to
work We test our pumps at
20 psi of pressure
Put a 3” Male NPT plug in the
exhaust port and a similar
adapter that can connect to a
controlled pressurized air supply
in the inlet
Spraying your pump with soapy
water while pressurized will
expose any bubbling air leaks in
your vacuum pump
30 Reconnect the pump to its
oil reservoir and start at a
slow R P M
Run the pump for a few min-
utes to allow oil to fill the lines.
Inspect the translucent oil lines
to check that oil is flowing.
