Pressure Relief Procedure

Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury from
splashing.
1. Shut off the air supply to the pump.
2. Open the dispensing valve, if used.
3. Open the fluid drain valve to relieve fluid pressure.
Have a container ready to catch the drainage.

Flush the Pump Before First Use

The pump was tested in water. If water could
contaminate the fluid you are pumping, flush the pump
thoroughly with a compatible solvent. See Flushing and
Storage, page 17.

Tighten Fasteners Before Setup

Before using the pump for the first time, check and
retorque all external fasteners. Follow Torque
Instructions, page 18. After the first day of operation,
retorque the fasteners.

Starting and Adjusting the Pump

1. Be sure the pump is properly grounded. Refer to
Grounding on page 9.
2. Check fittings to be sure they are tight. Use a
compatible liquid thread sealant on male threads.
Tighten fluid inlet and outlet fittings securely.
3. Place the suction tube (if used) in 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.
4. Place the end of the fluid hose into an appropriate
container.

5. Close the fluid drain valve.
6. Back out the air regulator knob, and open all
bleed-type master air valves.
7. If the fluid hose has a dispensing device, hold it
open.
8. Pumps with runaway protection: Enable the
prime/flush function by pushing the prime/flush
button on the DataTrak.
9. Slowly increase air pressure with the air regulator
just 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.
NOTICE
When replacing Husky 1040s: The Husky 1050
operates more efficiently than did the 1040. Reduce air
inlet pressure by approximately 20 percent to maintain
an equivalent fluid output.
