Installation and User’s Guide
Section 3
Adjustments
After completing the installation,
turn the pool pump on
and allow it to run for a couple of minutes to ensure that
all air cycles out of the system. The SandShark
™
should be moving about the pool at a rate of 10 to 14 feet per
minute. Check each of the following initial adjustments as described in this section to the SandShark
™
at this time.
NOTICE:
Each pool’s hydraulic system and vacuum connections are different. Be sure you have installed the
vacuum regulator
before you “fine-tune” the system. This not only regulates vacuum, but also acts as a safety device.
WARNING
—
Suction entrapment, injury, and drowning hazard.
If your pool has a dedicated suction port
(“vac port”) for vacuuming or for an automatic pool cleaner, it must be covered when not in use. A
spring loaded safety cover (the “Vac Port Fitting”) is included with this pool cleaner. Install it on the
vac port to prevent entrapment and injury. For details please refer to the Vac Port Fitting instruction
sheet included with your cleaner.
Hose Adjustments
Hose Length
IMPORTANT:
The pump must be on when you check the hose length. The hose contracts when the pump is
operating and will be longer when the pump is off.
With the SandShark
™
operating, position it at the furthest point of the pool from where it’s attached. (It is easy to
position SandShark
™
in the pool by moving it about with your pool pole and brush.) SandShark’s hose should be
long enough to reach the end of the pool, plus one hose section, plus the 12 in. leader hose. If necessary, remove
extra hose sections from the center portion of the hose. Removing center hose sections avoids having to disturb
the hose weight placement. Save extra hose sections for use as needed for replacement.
NOTE:
Turn pool pump off when adding or removing hose sections.
Hose Balance
It may or may not be necessary to add weight to your hose, depending on your pool’s size, shape, and depth. Try
the cleaner first without any hose weights. If the hose is too buoyant, add the weight as shown in Figure 26.
To determine correct hose balance,
turn the pump off
and observe
SandShark
™
. Hose balance is correct
when SandShark’s rests flat on the
pool floor. SandShark
™
achieves the
best cleaning coverage when the hose
neither weighs down nor pulls up on
the unit. Adjust hose weights one inch
at a time as needed, until proper hose
balance is achieved. In pools with both
shallow and deep areas, adjust hose
weights first in the deep area and then
in the shallow area.
