Use Protective Basket to prevent entrapment when the Regulator Valve is connected to 

a Dedicated Vacuum Port.

1.  Close the main drain and all suction lines except the one to which you are connecting the 

PoolShark. 

2.  Turn off the main circulation pump. 
3.  If necessary, insert the Reducer Cone into the dedicated vacuum line port. 
4.  Place the PoolShark (with the Hose Asembly attached) in the pool with the bumper facing 

downward. Tilt it from front to back and from side to side to purge all the air from the 

inside of the cleaner body. 

5.   Allow the PoolShark to sink to the pool floor. While holding the free end of the hose, feed 

the hose down into the pool until it is completely filled with water and purged of air. 

6.  Attach Regulator Valve #1 (with the Regulator Valve Cover) to the hose end. Insert 

Regulator Valve #1 (with hose attached) into the short extension hose. Insert the short 

extension hose into the male-male adapter and the entire assembly into the dedicated 

vacuum line port.

Initial Adjustments And Operational Checks

 

1. 

Purge remaining air:

  

After completing the installation turn the main circulation pump on. Allow it to run for a 

couple of minutes to purge any remaining air from the system. 

2. 

Check/Adjust Suction:

  

1. If you have not already done so, clean the filtration system (including backwashing, if 

that is appropriate to your system).  

2. If you have not already done so, close the valve controlling the flow through the main 

drain in the floor of the pool. 

3.  Adjust the pool circulation system valves to provide a sufficient flow of water to your 

Skimmer or Dedicated Vacuum Line (whichever you have decided to use). 

4.  To determine whether or not you have the suction correctly adjusted, look at the Regulator 

Valve and make sure that the Yellow Band is half covered by the edge of the sleeve (See 

Figure 5). Operation within the Yellow Band indicates the best suction adjustment for good 

cleaner performance.
