OPERATION
Open Delivery
Exhaust Primer
International Only: The exhaust primer is used for
priming of pump installations with suction inlets in
an Engine Generator Pump Application. See Figure
59-1.
1. Close the riser pipe valve.
2. Start the engine and insert the primer slide into
the primer assembly, diverting exhaust to the ex-
haust primer. As the exhaust passes through the
exhaust primer it creates a vacuum in the hose
running to the inlet pipe. The vacuum pressure
is displayed on the engine control panel vacuum
gauge.
3. Adjust the engine RPM to achieve the maximum
vacuum reading possible on the engine control
panel vacuum gauge.
The vacuum will pull air out of the inlet pipe and
pull water into the cavity. The inlet and pump cav-
ity will be full of water and primed when water
begins to spray out of the exhaust primer.
4. Remove the primer slide from the primer assem-
bly.
5. Slowly open the riser pipe valve to fill the system
with water.
6. After riser pipe valve is completely open and the
system is full of water, bring the engine up to its
operating RPM.
Compressed Air Primer
The vacuum pump compressed air primer is used for
priming of pump installations with suction inlets in an
Engine Generator Pump Application. See Figure 59-2.
1. Close the riser pipe valve.
2. Connect compressed air line to the vacuum
pump and open the vacuum pump valve.
3. Apply 45 to 50 psi of continuous compressed air
pressure to the vacuum pump.
4. Start the engine. As the air passes through the
vacuum pump it creates a vacuum. The vacuum
pump will pull air out of the inlet pipe and pull
water into the cavity. The vacuum pressure is
displayed on the engine control panel vacuum
gauge. The inlet and pump cavity will be full of
water and primed when water begins to spray out
of the vacuum primer.
5. Slowly open the riser pipe valve.
6. After riser pipe valve is completely open, close
the vacuum pump valve, bring the engine up
to its operating RPM and disconnect the com-
pressed air line.
