under the water and count
the wheel revolutions for
one minute.
4. Wheel RPM should be 28-32.
SERVICE:
If the pressure is more than
32 RPM:
For 380:
1. Install a blue UWF Restrictor
(part #10-108-00) if one is not already installed.
2. Replace the blue UWF restrictor with the red UWF restrictor.
3. Unscrew the pressure relief valve until the proper RPM is reached.
For 360:
1. For dedicated cleaner line, adjust the pressure relief valve.
2. For after market installations, open up the holes on the return jets
until desired wheel RPM is achieved.
If the pressure is less than 28 RPM:
For 380:
1. Remove the UWF restrictor if one is installed.
2. Verify there is adequate water pressure (28-32 psi). (Refer to page 25.)
3. Check the drive train. (Refer to page 33.)
4. Check the drive jet. (Refer to page 29.)
5. Check the o-ring between the feed pipe/timer blank assembly and
the
water management system.
6. Check the water management system hoses for leaks and loose
hose clamps.
For 360:
1. For dedicated cleaner line, adjust the cleaner line valve.
2. Back wash or clean the filter.
3. Clean skimmer and pump baskets.
4. Clean filter screen.
5. Check for excessively leaking swivels.
6.
Install smaller eyeballs in return lines (Eyeball Regulator,
part #10-107-
00).

open up a return line. If that doesn’t work, make the holes in the
adjustable eyeball larger.
If the pressure is too low:
For 380:
1. Check the filter screen for debris.
2. Make sure the pressure relief valve is screwed in completely. If it is and
water is being released, replace the pressure relief valve.
3. Remove the UWF restrictor if one is installed.
4. Check hose and swivels for leaks.
5. Completely open the gate valve on the booster pump if there is one.
6. Make sure the skimmer basket and pump basket are
clean.
7. Check the pump hose washers
for swelling (old style black hoses), see
picture on page 25.
8. Remove the pressure restrictor in the pump if one is installed.
9. Verify the pump installation is correct. (Refer to page 31.)
10. Check for kinked or collapsed booster pump hoses.
11. If there is an over-the-deck installation, make sure the feed hose is at
least 3/4 inch in diameter.
For 360:
1. Check the filter screen for debris.
2. Make sure the pressure relief valve is screwed in completely. If it is
and water is being released, replace the pressure relief valve.
3. Remove the UWF restrictor if one is installed.
4. Check hose and swivels for leaks.
5. Make sure the skimmer basket and pump basket are
clean.
B. Wheel RPM
For 380: When checking wheel RPM, you should also check water pressure
(see Section A on the previous page). 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. Mark the single-side wheel.
2. Turn on the filtration and
booster pumps, and allow the
back-up valve to complete a
back-up cycle.
3. Hold the cleaner completely
