11. On the clear hose, make sure one float is
against the back-up valve on the side oppo-
site the cleaner and another float is upstream
within 2-3 feet. On the white hoses, space
the floats no less than 1-1/2 feet and no
more than 3 feet apart, so the white hoses
do not sag. It may be necessary to remove
floats to maintain proper spacing.
12. When the feed hose has been cut properly,
it should look like the one in the "Properly
Sized Feed Hose" diagram on page 4.
E. Assembling the Polaris
1. Put the nut on the feed pipe. Attach the clear
hose to the feed pipe and tighten the nut.
If there is a curve at the end of the hose,
align it with the curve of the feed pipe.

2. Pull out the bag. With the bag on the single-
wheel side of the feed hose, snap the bag
collar onto the feed hose.
3. Turn on the pool filtration pump. Wait at least
30 seconds and turn on the booster pump.
F. Checking Operation
When operating correctly, the Polaris 280 will
travel randomly throughout the pool, vacuuming,
sweeping and scrubbing the bottom, sides, and
most of the steps and swimouts. The Polaris will
clean an average pool in 3 hours or less.
The Polaris comes equipped with an automatic
pressure relief valve in the quick disconnect. If the
Polaris is receiving too much water pressure, it will

release water at the quick disconnect. The wheel
RPM of the Polaris should be between 28 and 32.
Approximately every 2 minutes the Polaris 280
will go into back-up mode. At this time the back-
up valve will pull the Polaris away from potential
obstacles and increase its random pattern.
The sweep hose operates in a gentle sweeping
motion to prevent debris from becoming trapped
in hard-to-reach corners of the pool.
If the Polaris does not operate as described
above, turn off the pumps and make the neces-
sary adjustments below.
G. Fine Tuning

1. Thrust Jet Adjustment

The position of the thrust jet determines the
direction of the Polaris. Its standard position
is straight back.
To change the direction of the thrust jet, loosen
(but do not remove) the screws, and move the
thrust jet to the desired position. Retighten the
screws, being careful not to overtighten. For the
location of the thrust jet, see the Exploded Parts
Diagram on page 14.

2. Head Float Adjustment

The head float keeps the cleaner stable and
in an upright position. Its standard position is
between 1/2 to 1 inch from the feed pipe.
Moving the float out from the feed pipe will keep
the nose down. Moving the float completely
forward, toward the feed pipe, will increase the
climbing ability. For the location of the head float,
see the "Assembling the Polaris" diagram.
