2. 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.
3. 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 pres-
sure 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.
4. Checking Wheel RPM
To determine whether the Polaris is receiving
proper 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 by the blue top, suspended on
its side just below the water level.
➔ 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:
•
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.
If the Polaris is still operating above 32 RPM,
unscrew the pressure relief valve (#44 on
page 16) until the proper RPM are reached.
If the Polaris is operating below 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.
•
Reinstall the universal wall fitting.
•
Recheck the wheel RPM.
If you still have less than 28 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.
