VIII. HOW TO CHECK AND SERVICE
A. Pressure
For 380: When checking water pressure, you should also check wheel RPM
(see Section B on page 26). Water pressure should not exceed 32 psi and
wheel RPM should not be lower than 28. Also, water pressure should not
exceed wheel RPM by more than 2 psi.
For 360: Water pressure should be between 12-14 psi, and wheel RPM
between 28-32.
CHECK:
1. Attach the pressure stick to the
end of the feed hose.
2. Turn on the filtration pump and
then the booster pump.
3. Hold the end of the pressure
stick under the water.
4. The pressure should be
between 28-32 psi for the 380
and between 12-14 psi for
the 360.
Note: Use a 0 - 60 psi gauge for
the 380, and a 0 - 30 psi gauge
for the 360.
SERVICE:
If the pressure is too high:
For 380:
1. Install a blue UWF
Restrictor (part #10-108-00)
if one is not already installed.
2. Replace the blue UWF restric-
tor with the red UWF restrictor.
3. Unscrew the pressure relief
valve until the pressure is 28-
32 psi.
For 360:
1. If there is a dedicated line,
adjust the valve until proper
psi is achieved.
2. For after market installations,

PROBLEM: Cleaner runs on its side.
SOLUTION:
1. Verify the bag is empty.
2. Check the head float. If it has
water in it, replace it.
3. Verify the hose floats are float-
ing and spaced properly.
(Refer to #4 on page 5.)
4. Check the feed hose for leaks.
5. Check the vacuum jets. (Refer
to page 29.)
