Problem:
No water pressure flow in the wash tub.
Solution:
Check water flow from incoming water line. Check pressure gauge on water column
in cabinet of APW. The unit requires 40-50 PSI to function properly. If you have sufficient flow
form the incoming water line, and 40-50 PSI of required pressure, you will need to adjust the
flow screw [

]. Start by counting the number of
turns it takes to close the screw when tightening (clockwise). The flow at the wash tub should
not be very low. Now loosen the screw (turning counter-clockwise) approximately 1
¾
- 2
turns, which should increase the flow. Keep in mind the more you loosen the flow screw to the
left the more you will increase the flow, but will be decreasing the suction for the shampoo.
Problem:
One of the shampoos or treatments in not flowing correctly.
Solution:
With the sprayer in the on and locked position, select the soap or treatment that’s
malfunctioning. If everything is working properly, you should have a low pressure flow with
soap and water. If you’re not receiving any soap along with the water, head to the equipment
room and locate the soap containers. Screw off the cap of the soap or treatment that’s mal-
functioning and examine the suction strainer. Make sure the screen is clean, if not, run the
suction strainer under some clean water. Next, examine the clear tube running from the soap
to the water column. If you are getting air bubbles in the tube, the soap is flowing but your
concentrate may be too diluted to see the soap coming out of the sprayer. If you are still
having issues you can increase the flow by loosening the material volume screw.
Problem:
Vacuum is running, but has no suction.
Solution:
Check the hose for obstruction. With the vacuum cleaner off, use the water
flush valve and flush the vacuum. Make sure water is flowing out of the vacuum. Once
completed, run the vacuum and check for suction. If you still do not have suction, you will
need to remove and clean the vacuum motor and filter. You can also remove the black drain
hose from the check valve at the bottom of the vacuum and then turn on the vacuum. At this
point feel if you are achieving suction back threw the check valve. If you are the check valve
flap is not sealing tight and needs to either cleaned or replaced. Clean the filters as needed.
Problem:
Water is not pumping out of the hair strainer tank.
Solution:
The pump float switch is stuck. Simply unlodge the pump float. Rinse out tank as
needed.
Problem:
Floor pumps are not functioning correctly.
Solution:
Ensure that hair is not clogging the release hole at the base of the floor pump tube.
If clear, spray water directly at the probes to remove any excess film build-up. When film
accumulates, the build-up will not allow the probes to function properly.
