Start And Adjust The Pump; Pump Shutdown - Graco Husky 1050HP Operation

Operation

Start and Adjust the Pump

1. Be sure the pump is properly grounded. Refer
to Grounding, page 8
2. Ensure the High/Low pressure lever is in the
"Low" position before starting the pump.
3. Check all fittings to be sure they are tight. Use
a compatible liquid thread sealant on all male
threads. Tighten fluid inlet and outlet fittings
securely.
4. Place the suction tube (if used) in the fluid to be
pumped.
NOTE: If fluid inlet pressure to the pump is more
than 25% of outlet working pressure, the ball
check valves will not close fast enough, resulting
in inefficient pump operation.
Excessive fluid inlet pressure can reduce
diaphragm life and may result in pump damage.
5. Place the end of the fluid hose into an appropriate
container.
6. Close the fluid drain valve.
7. Turn the air regulator knob to 0. Open all
bleed-type master air valves.
8. If the fluid hose has a dispensing device, hold
it open.

9. Slowly increase air pressure with the air regulator
until the pump starts to cycle. Allow the pump to
cycle slowly until all air is pushed out of the lines
and the pump is primed.
NOTE: Use lowest possible air pressure to prime,
just enough to cycle the pump. If the pump does
not prime as expected, turn air pressure DOWN.
10. If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses.
11. Close the dispensing valve, if used.
12. Close the bleed-type master air valve.

Pump Shutdown

At the end of the work shift and before you check,
adjust, clean or repair the system, follow the
Pressure Relief Procedure, page 13.
