Important Recommendations; Maintenance Tips - Hayward PoolVAC Ultra User Manual

Remove the vacuum gauge from the hose and keep
it within easy reach. You will need it from time to
time to check the operation of the cleaner.
Important: Remove the AEV096 vacuum gauge
after adjusting the cleaner. It is not designed to
be left in the water and is not covered by the
warranty.
Step 8. Observe the cleaner in operation. The dis-
charge of water into the pool may affect the cleaner,
either at the hose on the surface or with the cleaner
itself at the bottom of the pool. If the pool's dis-
charge can swivel, turn it so the flow of water does
not interfere with the movements of the cleaner.
Otherwise, ask your dealer to help find a solution.
Step 9. Check that the cleaner moves without stop-
ping too long at steps and other obstacles (vertical
walls, ladders). If it seems to you that the cleaner
is stuck, set the rear flap adjustment knob to I (see
figure 3).
Step 10. The cleaner climbs the vertical walls of
cement and fiberglass pools provided that they join
the pool bottom in a smooth curve (radius at least
30 cm). When the cleaner climbs a wall, It may
stop short of the top. If the cleaner seems not to
grip the wall, set the rear flap adjustment knob to
III (see figure 3).
If the cleaner reaches the water surface and takes
in air, set the rear flap adjustment knob to I (see
figure 3). If the cleaner still climbs too high, reduce
the suction power by 25 mm (1'') until operation
becomes normal.
About 80% of pool residues are on the bottom, the
remaining 20 % on the walls, so the cleaner spends
more time cleaning the bottom than the walls.
Because of the shape of most sunken liner pools
(corners too sharp), the cleaner is confined to the
bottom (whatever the depth) and sloping walls. The
cleaner does not climb vertical liner walls.
Now that your cleaner is installed and working prop-
erly, enjoys your pool.

IMPORTANT RECOMMENDATIONS

1. Check regularly that the hose of the cleaner
is properly connected to the skimmer suction
port.

2. Disconnect the hose of the cleaner beforeback-
washing the filter. This is to ensure the flow of
water needed for effective back-washing.
3. Never coil the hose of the cleaner. The war-
ranty does not cover problems caused by
coiled hoses.
4. Warning: If massive chlorination is applied, it
is essential to remove the cleaner and its hose
from the pool until the chlorine level returns to
normal.
5. Always disconnect the main hoses from the
cleaner head when the latter is not in the pool.
6. Always carry and lift the cleaner by its handle,
never by the hose.
7. Remove the cleaner and its hose from the pool
before using the pool.
8. Check the vacuum regularly using the vacuum
gauge. Too much or too little suction is harmful.
9. Keep the back grate clean and free of debris by
regular brushing.
Remark: Bear these points in mind when install-
ing your cleaner.

MAINTENANCE TIPS

The cleaner has a «removable bottom». The pur-
pose of this feature is readier access to the turbine/
suction chamber unit for servicing or cleaning.
Should the cleaner stop or slow down too much
because of the build-up of residues in the neck or
inside the device, you can reach the turbine/suction
chamber unit (see figure 11).
DISCLAIMER
1. Ageing, sunlight, and chemical treatments
damage the liner.
2. The liner may be weakened and become brittle.
3. The pool's installation and environment may
also affect the liner.
4. When you install your cleaner, you take com-
plete responsibility for the condition of your pool
and its environment.
