Preparation

• Since Manta Ray™ runs off of your filter system, your cleaner’s performance is directly related to your filter’s performance. The better your filter is operating, the better your cleaner will work. Take these steps to ensure filter and cleaner performance:

• Clean your Pool

• Backwash your filter or Clean the filter element

• Clean out your skimmer basket and the pump’s strainer basket

• Chemically balance your pool
  

• Prime the vacuum hose: put the end of the hose up to the pool’s return with the pump running. This will force water through the hose and purge out the air. Keep the pump running until there are no air bubbles coming out of the end of the hose.
  

• For pools with 2 suction lines (i.e. main drain and skimmer or 2 skimmers) it is necessary to close off the suction line that is not being used for the cleaner. Do this by turning off the valve for the main drain, or use a skimmer bypass plate to restrict water flow.
  

• Periodically check your filter pressure and backwash your filter or clean your filter element.
  

• Remove all obstructions from the pool – ladders, floats, toys and other items that could limit Manta Ray’s ability to navigate the pool.
  

• Do not coil the hose when taking the cleaner out of the pool. Doing so may cause the hose to retain the coiled shape which could hinder the cleaner’s performance.

Manta Ray Winter Storage

• Remove your Manta Ray pool cleaner from the pool and let it dry completely

• Disassemble the hose sections and store in original box or lay out on a flat surface – NEVER store the hose in a coiled position.

• Store Manta Ray so that the pleated seal lays flat, or remove the seal and store it in a flat position.

• Store all parts indoors.

Hose Balance

You may need to attach hose weights to neutralize the hose’s buoyancy in the water. With the cleaner turned off, the hose balance is correct when the cleaner’s seal rests flat on the pool floor and the main body makes a 45 degree angle with the pool floor. Your Manta Ray vacuum will produce the best results when the hose neither weighs down or pulls up the unit.

Above Ground Pools
Typically one weight is needed, placed 4-12” away from the body’ swivel head.

In Ground Pools
Typically all 3 weights are needed. The first should be placed on the first section of hose between 4-12” from the body’s swivel head; the next 2 weights should be positioned 6’ and 10’ from the body respectively.


Adjust weights one inch at a time as needed, until proper balance is achieved:

• HOSE IS TOO LIGHT – if the hose rises toward the surface at an angle greater than 45 degrees, move the weight closer to the cleaner.

• HOSE IS TOO HEAVY – if the hose sags downward at an angle less then 45 degrees, move the weight away from the cleaner.
