NOTICE:
If the skimmer does not allow you to see the
Yellow Band on the Regulator, the following TEMPORARY
procedure will let you check the suction:
A. Turn off the Pump.
B. Detach the Regulator Valve from the skimmer’s suction
inlet.
C. Insert the Regulator Valve in the joint between the last
and the next to the last sections of hose.
D. Reconnect the hose to the skimmer.
E. While a helper holds the regulator under water (so that
it won’t suck air – see Figure 6), Turn the pump on and
make the valve adjustments described in Steps 2 and 3
(Page 4).
F. When you have finished the valve adjustments, stop
the Pump, reconnect the hoses, and replace the
Regulator in the skimmer.
Do you have enough vacuum on the system for good
operation?
1. If you have not already done so, clean the filtration sys-
tem (including backwashing, if that is appropriate to
your system).
2. If your system is clean and the cleaner still performs
sluggishly, try inserting Regulator Valve #2, which is
designed for use with weaker pumps, longer hose
lengths, or low suction situations.
The installation of Regulator Valve #2 is the same as the
installation of Regulator Valve #1. See “Installation”,
Page 3.
NOTICE:
After you have installed Regulator Valve #2, ad-
just the circulation system valves as described in Steps 3
and 4 (Page 4).
Do you have too much vacuum?
You have too much vacuum if the PoolShark sucks air
when it climbs up to the water line. Check to be sure that
you have installed Suction Regulator Valve #1. If not, in-
stall it now. If the PoolShark still climbs out and sucks air,
do the following:
1. If you are connecting the PoolShark to the Skimmer,
slightly
open the main drain valve.
2. If you are connecting the PoolShark to the Dedicated
Vacuum Line,
slightly
open the skimmer intake valve.
3.
Check the hose length:
The main circulation pump must be running when you
check the hose length. The hose contracts when the
pump is on and will look longer when the circulation
pump is off or the hose is disconnected from the sys-
tem. Position the PoolShark at the furthest point of the
pool from the skimmer or dedicated suction port. The
hose should be long enough to reach this distance,
with one hose section over.
If your hose is more than one section longer than the
distance to the furthest point of the pool, remove the
extra section(s) from the end of the hose at the vacuum
port or skimmer. Save these extra sections for future use
as replacements.
4.
To install the eyeball diverter:
The water flow from the return line can push the
PoolShark’s hose, causing the PoolShark to steer away
from the return line or to remain in one area of the
pool. To correct this, adjust your existing return line di-
verters or install the eyeball diverters supplied with the
PoolShark 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 PoolShark’s eyeball diverters.
D. Replace the lock rings and tighten them. Be sure
that the openings of the eyeball diverters point
down or to the side (9:00 O’clock position), 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 circula-
tion pump on. The PoolShark should begin moving
across the pool floor, vacuuming up the debris in its
path.
E. If the PoolShark’s eyeball diverters do not fit your
existing return line fittings, adjust your existing fit-
tings as best you can as described above.
