Section 2

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.
