PUMP PRIMING INSTRUCTIONS

1. Refer to section II-g to ensure all electrical connections are complete.
2. Connect supply water with a 1" (AX and BX Models) or 1-1/2" (TX Model) Inlet Line and open feed
line (Minimum 2 psi required)
3. Pull each pump discharge quick-connect until a steady stream of is flowing, and then reconnect.
4. 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.
5. TX Model: Slowly open the priming ball valve located off the end of the distribution block and allow
water to flow until steady, then close the valve (a hose could be connected to the valve to the drain to
avoid excessive water on the floor)
6. AX and BX Models: With the pump off disconnect the high pressure line to the AquaLab at the quick
disconnect and point in a safe direction, while holding the line to control it start the pump and allow
water to flow until steady.
7. Close the ball valve (TX Model) or reconnect the high pressure line at the quick disconnect (AX and
BX Models)
8. Confirm that the pumps can obtain 200 psi and that the pump housing is cool to the touch after a
minute in operation.
9. If pump does not prime, repeat steps 3-6
• !!Pay close attention to the temperature of the pump housing, if it starts getting hotter than the
supply water then it is likely that the pump did not prime correctly!!
• *WARNING* If the pumps do not prime correctly they will heat up and it will cause damage to
the pumps.

WATER FLOW RATE AND CHEMICAL DILUTION SET UP

For each of the chemicals that the Aqua-Lab is delivering to the car wash bay follow the steps outlined
below to set the overall flow rate and chemical dilution. NOTE: you will need to know the target flow rate
and chemical dilution (concentration) prior to setting up each chemical.
