Pump Priming Instructions
1. Pull each pump outlet line at AQUA-LAB manifold quick-connect. Open ball valve until a steady stream of water is
flowing, and then reconnect.
2. Start the pumps one at a time using the motor starter . Ensure
that pump rotation is correct
as indicated on pump and
that 200 psi can be reached.
o Remove pump motor cover and look at shaft to confirm correct
rotation (clockwise)
3. With the pump off, close the ball valve on the high pressure line to the
AQUA-LAB.
4. Quick disconnect the line at the AQUA-LAB manifold and point in a safe direction.
5. Hold the line to control it and start the pump; slowly crack the ball valve approximately 15 degrees open for 10
seconds.
6. Slowly open ball valve till wide open. Allow to run for 60 seconds to flush lines and then close valve.
7. Reconnect the high pressure line at the quick disconnect and open valve.
8. Confirm that the pump can obtain 200 psi while firing solenoids and that the pump housing is cool to the touch
after a minute in operation.
o If housing is hot or noisy then pump did not prime.
9. If pump does not prime, repeat steps 3-6
10. Verify pump prime 24 hours after operation as well to ensure prime held!! Pay close attention to the temperature
of the pump housing (stainless steel area).If it starts getting hotter than the supply water or greater then 140°,
then it is likely that the pump did not prime correctly which will cause damage to pumps!! Motor housing (painted
portion) will be hot during operation.
