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

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 The following general information describes how to set-up your new SandShark™ automatic pool cleaner.
  NOTE : Before setting up this product, read and follow all warning notices and instructions starting

Preparation of your pool

Before you assemble and install your new SandShark™ automatic pool cleaner, you should make sure that your pool is clean and free of algae. If necessary, make the following preparations before proceeding:

• Chemically balance the pool water
• Brush the pool and let the debris settle
• Hand vacuum the pool thoroughly
• Backwash and clean the filter and clean the pump strainer basket, (see Figure 1)

Installation

This section describes how to install your new pool cleaner. The SandShark™ is designed to work in a wide variety of swimming pools. Both the standard in- skimmer installation and optional vac port installation are covered in these Instructions. If your pool configuration is unlike any of the examples, contact your Pentair Water Pool and Spa dealer for assistance, or call our toll-free Customer Helpline at 1-800-831-7133.

Standard Installation

WARNING — Hazardous suction. Suction through the SandShark™ 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 cleaner or its hoses.

For Pools with one Skimmer, using the Vacuum Regulator

The advantage of this installation is its use of the vacuum regulator to balance the water flow between the pool’s skimmer, (see Figure 7), and the SandShark™. The vacuum regulator, (see Figure 8), can be adjusted to changes in the amount of water flow to provide the SandShark™ with the power necessary to ensure proper cleaning performance, and we strongly recommend the use of the vacuum regulator valve for maximum safety and performance.

1. Turn the pool pump off.
2. Adjust valves for vacuuming. Adjust the pump valves (if your system has valves) to direct all suction to the skimmer. Close the main drain and all suction lines, except the line from the skimmer to which the SandShark™ will be connected.
3. Remove the skimmer basket from the skimmer.
4. The vacuum regulator must be installed in conjunction with the reducer cone, (see Figures 8 and 9). The reducer cone is required to make most skimmer connections. It will keep the hose and vacuum regulator in place once the filter system is stopped.
5. To install the vacuum regulator, insert it and the reducer cone in the skimmer. Attach the end of the hose to the regulator, (see Figure 10). Make sure the vacuum regulator is submerged at all times. If not, the pump will suck air and lose prime. This could damage the pump.
6. Submerge the hose so it fills with water and expels air from the hose. Attach one end of the hose to the vacuum source as described above. Keep the other end of the hose accessible.

Adjust Flow

1. With the main drain closed, and one end of the hose attached to the vacuum regulator installed in the skimmer, insert the flow gauge into the other end of the hose (the end with the “leader” hose attached).

2. Keep the hose and flow gauge underwater.

3. Turn on the pump. With the pump running, adjust the vacuum regulator (in your skimmer) until the indicator on the flow gauge is between minimum and maximum flow, (see Figure 11).

4. Use the vacuum regulator in conjunction with your pool cleaner system at all times. The vacuum regulator has an adjustment knob, (see Figure 12). If suction is too high, the knob is turned counterclockwise to decrease the suction. If the suction is too low, the knob is turned clockwise to increase the suction.
   NOTE : The flow gauge is calibrated for use with the “Y” shaped vacuumregulator valve. The flow gauge will not indicate the correct flow for the cleaner if you are not using the “Y” shaped vacuum regulator valve.

5. Remove the flow gauge from the end of the hose (the end with the “leader” hose attached) and attach the “leader” hose to the cleaner’s swivel.

Connect the Hose to the Cleaner

1. Connect the leader hose to the cleaner (correct end of hose is marked with a red label), (see Figure 13).
2. Fill the cleaner with water and let it sink to the bottom, (see Figure 14). 3. Verify hose connections as shown in Figure 15

Optional Installation

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.

Vac Port Installation with Vacuum Regulator in Skimmer

If your pool has a dedicated wall fitting “vac port”, (see Figure 16), you can install the SandShark™ using the

Optional Installation.

1. Turn the pool pump off.

2. Adjust valves for vacuuming. Adjust the pump valves (if your system has valves) to direct all suction to the dedicated vacuum line and the skimmer. Close the main drain and all remaining suction lines, except the line from the dedicated vacuum line to which your SandShark™ cleaner will be connected, and the skimmer where the vacuum regulator will be installed.

3. A spring loaded safety cover, (“vac port fitting”), is included with this pool cleaner (see Figure 17). Install it on the dedicated vacuum line to prevent entrapment and injury. For details please refer to the Vac Port Instruction sheet included with your vac port fitting. To install the included vac port fitting:

4. Screw the vac port fitting into the dedicated vacuum line opening.

5. Orient the vac port fitting so the arrow on the door points up.

6. Secure the cover by tightening the Allen-screw below the door, into the dedicated vacuum line fitting.

7. Remove the skimmer basket from the skimmer, (see Figure 18).
   WARNING — Hazardous suction. Can cause entrapment with severe personal injury or drowning

8. Insert the vacuum regulator and reducer cone in the skimmer, (see Figure 19). To prevent water from flowing through the top of the vacuum regulator, attach the regulator cap to the vacuum regulator.

9. Attach the end of the hose to the vac port fitting installed in the dedicated vacuum line, (see Figure 20).

Adjust Flow

1. With the main drain closed, and one end of the hose attached to the vacuum regulator installed in the skimmer, insert the flow gauge into the other end of the hose (the end with the “leader” hose attached).

2. Keep the hose and flow gauge underwater.

3. Turn on the pump. With the pump running, adjust the vacuum regulator (in your skimmer) until the indicator on the flow gauge is between minimum and maximum flow (Figure 21).

4. Use the vacuum regulator in conjunction with your pool cleaner system at all times. The vacuum regulator has an adjustment knob, (see Figure 22). If suction is too high, the knob is turned counterclockwise to decrease the suction. If the suction is too low, the knob is turned clockwise to increase the suction.
   NOTE : The flow gauge is calibrated for use with the “Y” shaped vacuum regulator valve. The flow gauge will not indicate the correct flow for the cleaner if you are not using the “Y” shaped vacuum regulator valve.

5. Remove the flow gauge from the end of the hose (the end with the “leader” hose attached) and attach the “leader” hose to the cleaner’s swivel.

Connect the Hose to the Cleaner

1. Connect the leader hose to the cleaner (correct end of hose is marked with a red label), (see Figure 23).
2. Fill the cleaner with water and let it sink to the bottom, (see Figure 24).
3. Verify hose connections as shown in Figure 25.

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 cleane

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.

Adjusting the Flow

1. Turn the pool pump off. Remove the Cleaner and connect the Flow Gauge 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” until the disc indicator in the Flow Gauge settles between “Maximum” and “Minimum” flow, (see Figure 28).
   NOTE : If you have very strong pump and the flow is still over the “Maximum” you may need to open the main drain only slightly.

3. Turn the pool pump off. Remove the Flow Gauge and connect the Cleaner 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 pump on.

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.

Return Line Water Flow Adjustments

Important : The cleaner must move randomly throughout the pool. Water circulating at the surface will influence the hose thus limiting the SandShark’s coverage. It may cause the SandShark™ to steer away from the end of the pool where the return line is located, or it may cause the SandShark™ to remain in one section of the pool. To correct this, use the eyeball diverter included with your SandShark™. (If the eyeball does not fit your pool, use the wire diverter (P/N K121620) accessory available for purchase from your Pentair Water Pool and Spa dealer.)

Eyeball Diverter Positions

1. Position the diverter opening to redirect the return line water flow so it does not interfere with the SandShark’s movement as shown in Figure 29.

2. To adjust the Eyeball Diverters; loosen the lock ring and redirect the Eyeball Diverters slightly downwards and also try different directions to see what works best in your pool.

3. flow directed along the side of pool (the tile line).

4. flow directed downward.

5. flow directed against the hose will help steer the SandShark™ away from obstructions such as stairs and ladders.
   Allow time for the body of water to settle into the new pattern.

6. If it is difficult to adjust your existing Eyeball Diverters, replace the eyeball component with the new Eyeball Diverters (included).

To install the eyeball diverter:

1. First make sure your pool pump is off. Remove the original eyeball from the return line at the pool by unscrewing the lock ring.
2. Replace the original eyeball with the SandShark’s eyeball diverter, (see Figure 30).
3. Replace the lock ring and tighten. Make sure the opening of the eyeball diverter points in the proper direction before tightening fully. See “Eyeball Diverter Positions” above.
4. After installing the eyeball diverter, turn the pool pump on. The SandShark™ should begin moving across the pool floor vacuuming up debris in its path.

In-Line Leaf Canisters
If your pool is exposed to large quantities of leaves, we suggest purchasing and installing an in-line leaf canister, (P/N R211084 or R211086), see Figure 31. A leaf canister will provide more debris-loading capacity and also provides a water by-pass when the canister is full. It is very important that the pump will not starve for water

Maintenance

This section describes the service and maintenance of your SandShark™ 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).

Disassembly

1. With a screwdriver, carefully work the rubber vacuum pad down over the lip of the Outer Housing, (see Figure 33).
2. Lift the Outer Housing straight up off of the chassis, (see Figure 34).
3. Squeeze and pull the Sprocket Clips to release the Drive Shaft Assembly and Center Sprocket, (see Figure 35).
4. Pull the Oscillator Straight out from the bottom of the Outer Housing. Be careful not to lose the Sliding Seals, (see Figure 36).
5. Squeeze the latching tabs and pull up on the Swivel Housing and Swivel. The assembly will come up, releasing the Swivel Sprocket. Squeeze the latching tabs to remove the Clutch Clip, (see Figure 37).
6. Remove the Shaft Plug with the stainless steel shaft and the Large Steering Drive Assembly, (see Figure 38).
7. Remove the Oscillator Sleeve, releasing the Oscillator Sleeve Bushing and the Clutch assembly, (see Figure 39).
8. If you need to replace the bumper, turn the housing/bumper assembly upside down and remove the two flex snaps holding the bumper to the housing, (see Figures 40 & 41). Use a piece of ½ in. (inside diameter) PVC pipe to slide over the flex snap ends to squeeze the flex snaps together so they can be slid out of the housing. Use a pair of pliers to pop the flex snaps off of the bumper.

Reassembly

To reassemble the SandShark™, reverse the steps above.
NOTE : The notch on the center disk of the Large Steering Drive Assembly must be down, (as shown in Figure 42), for assembly

If SandShark ™ **climbs pool wall to water surface and sucks air:| Reducewater flowthroughcleaner, seeAdjust Flowonpage4, 6or 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 ™ cleaner:**| Toinstall theeyeball diverter asfollows:

A.     Turnoff the maincirculation pump.

B.     Unscrewthelock rings fromthe pool’s returnlinefittings andremovethe original eyeball diverters.

C.    Replacethemwiththe SandShark’s eyeball diverters.

D.    Replacethelock rings and tighten them. Besure that the openings of the eye ball diverters point down(6:00 o’clock position) or to the eside(3:00 or 9:00 o’clock positions), before fully tightening therings.

Usually, directing the return line water flow against the side of the pool

(as described above) works best. However, you may want totry pointing the flow down wardor in different positions to see which works best in the pool. After installing the eye ball diverter, turn the circulation pump on.

The Sand Shark™should begin moving across the pool floor, vacuuming up the debris inits path.

E.     If the SandShark’s eyeball diverters do not fit your existing return line fittings, adjust your existingfittings as best youcanas described above.

If SandShark ™ **tracks in a repetitive pattern:**| Check the pool returnline water flowandredirect it as necessary with are turn line eyeball diverter (see above“Toinstall the eye ball diverter”).

Check the SandShark’s hose to be sure that it has not become bent or kinked. Do not coil the hose, asit will retain the coiled shape andreducethecleaningcoverage.

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. Replaceany sections which arebent or kinked.

Check the oscillator for: damage; lost seals (thereshouldbe4 seals): obstructed seals (seals should slide freely on the oscillator).

Be sure that the short, soft flexible leader hose section is the first section inthe hose assembly (next to the cleaner).
