380 Poolside Procedures
Polaris strongly recommends always following these troubleshooting
procedures. By using these procedures, most problems will be identified with-
in minutes. If you have any questions, please call 1-800-VAC-SWEEP.
With the Cleaner On:
Steps Recommendation
1. Check water pressure using It should be between 28-32 psi. Refer
the Pressure Tester (part #G-35): to page 25.
2. Check the wheel RPM: It should be between 28 and 32.
(Remember to hold the cleaner under
water when counting the wheel RPM.)
Refer to page 26.
The psi should not exceed RPM by
more than 2 psi.
3. Check that all jets are Turn the cleaner upside down. The
flowing unobstructed: three vacuum jets should have even,
unobstructed flow. Check the thrust
jet and sweep hose orifice. Refer to
page 29.
4. Check that the back-up valve The back-up jet cycles on and off.
is cycling properly: It should stay off longer than it stays on.
With the Cleaner Off:
Steps Recommendation
1. Check the feed hose length: • Clear hose length equal to greatest
depth of pool.
• Hard white hoses equal in length.
• Entire feed hose reaches within 6
inches of farthest point of pool.
• Floats on the white hoses spaced
evenly, 1-1/2 to 3 feet apart.

4. Verify that back-up valve is working correctly:
For the in-line back-up valve part #G-52 (380 serial #335727 or
higher) and part #9-100-1200 (360 serial #537791 or higher):
• Verify the in-line back-up valve is cycling.
• If not, open the valve and remove the mechanism.
• Separate the mechanism and inspect the turbine for debris.
• Flush or clear debris as necessary.
For the in-line back-up valve part #G-41 (380 serial #225071-335726)
and in-head timer assembly part #9-100-7006 (380 serial #K225070
or lower) and in-head timer assembly part #9-100-1003 (360 serial
#537790 or lower):
• Verify the valve/timer is cycling.
• If not, open the valve/timer and check the turbine jet for debris (380 jet
is red, 360 jet is white).
• If the jet is clear, replace the timer assembly or mechanism with in-line
back-up using an In-line Back-up Kit (380 part #9-100-9040; 360 part
#9-100-3200). Refer to Section H, Converting an In-head Timer to an
In-line Back-up Valve on page 31.
Even if the cleaner passes all of the Wet Function Bench Tests, it is always
a good idea to remove the tops and to do a visual inspection of the moving
parts, along with the water management system hoses and o-rings inside
the cleaner.
Once you have made any necessary repairs, run through the wet test one
more time. Verify all the functions are operating and that the basic factory
head adjustments are made to the thrust jet and head float. Then, with a
piece of black tape, mark a single-side wheel and remind the customer that
when reinstalled in the pool, the taped wheel should rotate at 28-32 RPM for
the 380/360.
Remember, being able to diagnose the problem the first time will build your
customer’s confidence in both you and the Polaris product. If you have any
question or would like to receive a free Wet Function Bench Test (Part #G-
110 for the 380 or part #9-100-6005 for the 360), please call our Technical
Support Department at 1-800-VAC-SWEEP.
