Sweep Hose Adjustment; Universal Wall Fitting Pressure Restrictors; Checking Wheel Rpm - Polaris 280 Owner's Manual

3. Sweep Hose Adjustment

The sweep hose should move in a gentle
sweeping motion. To decrease its motion, turn
the sweep hose adjustment screw clockwise.
See the "Assembling the Polaris" diagram on
page 6. Make sure the sweep hose scrubber
does not block the water flowing from the
sweep hose.
4. Universal Wall Fitting Pressure
Restrictors
The universal wall fitting comes with a blue
restrictor installed and an optional red restrictor
for use if needed. These special restrictors are
designed to work in combination with the pressure
relief valve. Together they will release excess
water pressure so the Polaris can operate at its
optimum level of efficiency. The red restrictor
provides maximum water restriction, while the
blue restrictor provides less restriction.
To determine whether a restrictor is needed,
follow the instructions below.

5. Checking Wheel RPM

To determine whether the Polaris is receiving pro-
per water pressure, turn off and carefully remove
the Polaris from the pool. Mark the outer edge of
a tire. Place the Polaris back in the pool and turn
on the pumps.
Hold the Polaris suspended on its side just below
the water level. Hold it away from the wall with
the marked tire up.

Hold the sweep hose to avoid being squirted.
Count the revolutions of the marked wheel for
exactly one minute, beginning after the Polaris has
completed a back-up cycle. This gives you the
cleaner's wheel Revolutions Per Minute (RPM).
For proper operation, the wheel RPM should be
between 28 and 32.
If the Polaris is operating above 32 RPM:
If the Polaris is still operating above 32 RPM,
unscrew the pressure relief valve (#46 on page 16)
until the proper RPM are reached.
If the Polaris is operating below 28 RPM:
If you still have less than 28 RPM:

Remove the universal wall fitting by attaching
the quick disconnect. Pull it away from the
pool wall as you unscrew the universal wall
fitting.
•
Push the blue restrictor out of the universal
wall fitting and snap in the red restrictor.
•
Reinstall the universal wall fitting.
•
Recheck the wheel RPM.

Push the blue restrictor out of the universal
wall fitting.
•
Reinstall the universal wall fitting.
•
Recheck the wheel RPM.
•
Clean the filter screen in the quick discon-
nect. A dirty filter screen will restrict the
water flow from the pump to the Polaris.
•
Check the hoses, connections, and swivels
for leaks that could cause loss of water
pressure.
•
If there is a gate valve installed on the
booster pump or the Polaris cleaner line,
open it completely so water can flow freely
to the Polaris.
•
Clean the skimmer and pump baskets.
