SANDSHARK
™
Automatic Vacuum Pool Cleaner Installation & User’s Guide
This section describes the service and maintenance of the of your SandShark
™
cleaner.
PROBLEM
CORRECTIVE ACTION
SandShark
™
moves slow or fails to climb walls:
Dirty Filter -
Dirty basket in pump hair and lint strainer –
Debris blocking the bottom of the SandShark
™
–
Leaks in the hose -
Debris in the regulator –
Low vacuum through the cleaner –
Clean the filter.
Clean the basket.
Remove the Debris.
Remove the leaky section.
Clean the regulator valve.
Close the main drain.
SandShark
™
doesn't move or pulsates slowly or doesn't
climb pool walls properly:
Make sure that the main drain and all other suction
lines are closed except the suction line to which the
SandShark
™
is attached.
Check for sufficient flow through cleaner hose.
Check for debris in the filter or the pump strainer
basket.
Check for debris in the SandShark’s oscillator. Debris
may prevent oscillator movement or restrict the flow
through the cleaner.
Check the oscillator for: damage; lost seals (there
should be 4 seals): obstructed seals (seals should slide
freely on the oscillator).
Be sure that the short, soft flexible leader hose section
is the first section in the hose assembly (next to the
cleaner).
SandShark
™
climbs pool wall to water surface and
sucks air:
Reduce water flow through cleaner, see Adjust Flow on
page 6 or 8.
The water flow from the return line can push the
SandShark’s hose, causing the SandShark
™
to steer
away from the return line or to remain in one area of
the pool. To correct this, adjust your existing return
line diverters or install the eyeball diverters supplied
with the SandShark
™
To install the eyeball diverter as follows:
A. Turn off the main circulation pump.
B. Unscrew the lock rings from the pool’s return line
fittings and remove the original eyeball diverters.
C. Replace them with the SandShark’s eyeball diverters.
D. Replace the lock rings and tighten them. Be sure
that the openings of the eyeball diverters point
down (6:00 o’clock position) or to the side (3:00 or
9:00 o’clock positions), before fully tightening the
rings. Usually, directing the return line water flow
against the side of the pool (as described above)
works best. However, you may want to try pointing
the flow downward or in different positions to see
which works best in the pool. After installing the
eyeball diverter, turn the circulation pump on. The
SandShark
™
should begin moving across the pool
floor, vacuuming up the debris in its path.
E. If the SandShark’s eyeball diverters do not fit your
existing return line fittings, adjust your existing
fittings as best you can as described above.
