GENERAL INSTALLATION INFORMATION
Pre-installation check list
Before installing your cleaner, review and understand all warnings and safety information in this guide. Failure to
follow these instructions or improper installation of the cleaner can result in damage to the pool finish or the vinyl
liner, Pentair Water Pool and Spa, Inc. disclaims any liability for repairs or replacement to any of these structures
or components of the customer’s pool.
Before installing the cleaner in a vinyl liner pool:
Check liner closely for signs of deterioration or damage from age, chemicals, pool wall damage, etc. If any
damage is found, have a qualified pool professional make all the necessary repairs. Also, if there are stones,
roots, etc., under the liner, remove them before installing the cleaner.
Before installing the cleaner in a gunite pool or a pool that is partially or completely tiled:
Repair loose tiles and tighten any loose light rings.
Before installing the cleaner, clean your filter system:
Make sure you have cleaned the filter, including backwashing, rinsing, and emptying all baskets. A clean
system is necessary for proper cleaner operation and coverage.
Before installing the cleaner, fill the hose with water:
Always make sure the cleaner head is submerged and the hose is full of water before connecting the hose to
the filtration system (whether through a skimmer or dedicated wall fitting). Air in the system can damage the
pump through dry running and overheating.
Before installing the cleaner, understand cleaner coverage:
The cleaner is designed to rid your pool of debris in approximately 4-6 hours. Less time could be needed,
depending on the pool size. The cleaner was not designed to automatically clean steps or swimouts or to
work under a solar cover. It was also not designed to do initial cleanup for a new pool or when opening your
pool for the season.
AFTER installing the cleaner, make sure the cleaner is operating correctly :
The cleaner may need some minor adjustments to make sure it is operating properly so there is no damage
to the pool finish. Certain vinyl liner patterns are particularly susceptible to surface wear, pattern removal, ink
rubbing off of, or serious scratches to the pattern caused by objects coming into contact with the vinyl surface,
including automatic pool cleaners. Pentair Water Pool and Spa, Inc. is not responsible for any pattern removal,
abrasions or markings on vinyl liners.

WARRANTY INFORMATION
Limited Warranty Terms & Conditions
Before installing your cleaner, review and understand all warnings, safety and warranty information in this guide. Failure to follow these
instructions or improper installation of the cleaner can result in damage to the pool finish or the vinyl liner, Pentair Water Pool and Spa, Inc.
disclaims any liability for repairs or replacement to any of these structures or components of the customer’s pool.
The Cleaner manufacturer, Pentair Water Pool and Spa, Inc. (“Manufacturer”), hereby provides the following limited warranty to the
purchaser (“Customer”): WHICH IS SUBJECT ONLY TO THE FOLLOWING CONDITIONS AND EXCLUSIONS:
This limited warranty does not include replacement of parts which become discolored due to exposure to sunlight or chemicals, or parts
which, even if worn, do not affect performance of the cleaner. Nicks, scratches, fading, discoloration, etc. are cosmetic conditions that
do not affect mechanical performance. Both Manufacturer and Pentair Water Pool and Spa’s dealer reserve the right to deny
any and all warranty claims made for worn parts if the wear does not negatively affect mechanical performance of the
cleaner.
The Cleaner is designed to function in a properly designed, constructed and maintained pool. This limited warranty does not extend in the
circumstances where the pool’s design, construction or maintenance is defective, substandard or inappropriate for the Cleaner’s
operation.
Deterioration, discoloration or brittleness of any pool finish can be caused over time separately by, or in combination with, age, an
imbalance in water chemistry, improper installation, and other factors. Customer hereby disclaims any and all claims, and releases
Manufacturer from any and all claims for damages to any pool plaster or vinyl liner in Customer’s pool by reason of the use and/or
operation of the Cleaner.
Under no circumstances shall Manufacturer be liable for any loss or damage, whether direct, consequential or incidental, arising out of the
use or inability to use the Cleaner or the Hose in Customer’s pool.
This limited warranty does not apply to any injury, loss, damage, defect, or malfunction of the Cleaner or failure to function resulting from

Disclaimer of Liability -
About Your Pool and SandShark™
There are a multitude of factors that contribute to the life of your pool. The SandShark™ automatic pool cleaner is a very passive product
that will have no impact on pool life.
Please be aware that over time, deterioration, discoloration and brittleness of any pool finish can be caused separately by, or in combination
with, age, an imbalance in pool water chemistry, improper installation and other factors. An automatic pool cleaner, such as SandShark™ ,
will not remove or cause wear on “good” pool plaster. In fact, the opposite is true–pool plaster will eventually cause wear on the cleaner.
The same situation holds true for vinyl-lined in-ground swimming pools, because vinyl liners are also affected by the environment and
factors such as pool water chemistry, sunlight and the pool’s surroundings. Therefore over time, vinyl can become brittle and weak. In
addition, vinyl-lined pools are affected by the workmanship, composition and installation of the liner and the workmanship and quality of
construction of the supporting walls and pool base. These are all factors which can contribute to liner failure. The existence of any of
these type of conditions in your pool is not caused by the use or operation of SandShark™ . The manufacturer disclaims any liability for
repairs or replacement to any of these structures or components of the customer’s pool.
The pool owner must assume all responsibility for the condition and maintenance of the pool’s surface, water and deck.

SandShark™Installation and User’s Guide
Section 3
Adjustments
After completing the installation, turnthe pool pumpon 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™atthis time.
NOTICE: Each pool’s hydraulic system and vacuum connections are different. Be sure you have installed the
vacuumregulatorbeforeyou“fine-tune” the system. Thisnotonly regulates vacuum,butalso acts asasafetydevice.
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 pumpoffwhen adding orremovinghose 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
balanceis achieved. In pools withboth
shallow and deep areas, adjust hose
weights first in the deep area and then
in the shallow area.

Adjusting the Flow
1. Turnthe pool pumpoff. Remove theCleaner andconnect the FlowGauge to
the end of the hose, make sure you keep the hose submerged to prevent any
air to enter into it, (see Figure 27). Then turn the pump on.
2. With the pump running, turn the Adjustment Knob of the Regulator Valve
“Faster”or“Slower”untilthediscindicatorintheFlowGaugesettlesbetween
“Maximum” and “Minimum” flow, (see Figure 28).
NOTE: If you have very strong pump and the flow is still over the
“Maximum”youmayneed toopenthemain drain onlyslightly.
3. Turnthepool pump off.Remove the FlowGaugeand connect theCleaner to
the end of the hose, make sure you keep the hose submerged to prevent any
air to enter into it. Allow the cleaner to drop to the pool floor. Then turn the
pumpon.
Too much Vacuum Flow?
You have too much vacuum if the cleaner climbs up the pool wall past the water
line to the point that the cleaner sucks air and the pump loses prime. Frequent
loss of prime will damage the pump. To correct this, adjust the regulator by
turning the adjustment knob counterclockwise. This will decrease the suction. If
the cleaner still climbs out and sucks air, open the main drain valve slightly.
Not enough Vacuum Flow?
You don’t have enough vacuum if the cleaner does not climb the pool walls, moves sluggishly, or not at all. Be
sure the filter system is clean and the regulator and all valves are adjusted to give you maximum vacuum. If the
cleaner is still not moving, your pump may not be strong enough to operate the cleaner. Please refer to the
“Troubleshooting Section” on page 13.

Maintenance
Thissection describes theserviceandmaintenance of yourSandShark™cleaner.
WARNING — Hazardous suction. Suction through the cleaner can entrap bathers, causing severe injuries or
drowning. Do not operate the SandShark™
cleaner while people are using the swimming pool. Do
not allow anyone to play with the SandShark™ cleaner or its hoses.
Your new pool cleaner requires almost no maintenance. Manually open and close the regulator valve from time to
time to flush away accumulated dirt and debris and ensure smooth operation. Also, from time to time, visually
inspect the SandShark™to be sure that:
• The oscillator moves freely and is not obstructed by debris.
• The vacuum pad is not excessively worn. When the traction pads on the bottom have worn down, it’s time for
replacement.
• Keep skimmer basket and pump strainer basket clean and free of debris.
• Remove the pool cleaner from the pool before super chlorinating (shocking) or chemical balancing. Wait at
least four hours after the chemical procedure before reinstalling the cleaner.
• If cleaner jams with large debris (leaves, sticks, etc.), clean the debris from bottom of unit.
• When people are using the pool, disconnect the cleaner and pull it to one side of the pool.
• We recommend that you leave the SandShark™cleaner in your pool, except during chemical shock
treatments.
Hose Storage
NOTICE: When storing the SandShark™, do not coil the hose. Instead, lay it out straight and flat in an area
protected from direct sunlight. If hose sections are disconnected, try not to disturb the hose weight locations. Use
only a genuine SandShark™hose. The warranty is void if the cleaner is operated with another hose other than a
genuine SandShark™hose.
• Remove the hose from the cleaner
when removing the cleaner from
the pool. Store the hose flat and
straight.
• Don't store the cleaner with the
hose connected to the cleaner
body or with the hose coiled, see
(Figure 32). To do so will cause
the hose to take a set or kink over
a period of time. When reinstalled
in the pool, the hose will tend to
stay coiled and will cause the
cleaner to malfunction.
• If the hose has taken a set, uncoil
it as far as possible without
damaging it and lay it out in the
sun for several hours to straighten itself. Once it has relaxed and straightened out, store it laid out flat and
straight (no coiling).
HOSE STORAGE
Best: Hose stored correctly – laid
out straight, not connected to
cleaner.
Wrong: Storing cleaner with hose
connected will damagehose and
void thehose warranty.

Troubleshooting
Usethefollowingtroubleshooting informationto resolvepossibleproblemswithyour SandShark™poolcleaner.
Problem Corrective Action
If SandShark™
moves slow or fails to climb walls:
Dirty filter – Clean the filter.
Dirty basket in pump hair and lint strainer – Clean the basket.
Debris blocking the bottom of the cleaner – Remove the Debris.
Leaks in the hose – Remove the leaky section.
Debris in the regulator – Clean the regulator valve.
Low water flow through the cleaner – Close the main drain.
If SandShark™ doesn’t move or pulsates slowly Make sure that the main drain and all other suction lines are closed except the suction line
or doesn’t climb pool walls properly: 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).
If SandShark™ climbs pool wall to water surface Reduce water flow through cleaner, see Adjust Flow on page 4, 6 or 8.
and sucks air:
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.
If SandShark™ tracks in a repetitive pattern: Check the pool return line water flow and redirect it as necessary with a return line
eyeball diverter (see above “To install the eyeball diverter”).
Check the SandShark’s hose to be sure that it has not become bent or kinked. Do not
coil the hose, as it will retain the coiled shape and reduce the cleaning coverage.
To check the hose, lay each hose section flat on the pool deck (or another flat surface)
and look down the length of the hose. It should be perfectly flat and straight. Replace any
sections which are bent or kinked.
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).
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™cleaner:
