IMPORTANT TIPS
Periodically check the water flow/vacuum to be sure that your
Cleaner is operating as efficiently as possible.
Remember, too much vacuum is just as bad as too little.
Periodically check to make sure that the Cleaner hose is securely
attached to its suction source (i.e. Skimmer, Vac Lock, etc.)
Disconnect the Cleaner hose from the Skimmer/Regulator Valve,
or, if using a "dedicated line," turn cleaner valve off prior to
"backwashing", so as not to restrict water flow.
DO NOT COIL HOSE
When storing your Cleaner, the hose sections must be stored
straight. A coiled hose will create a memory in the hose that will
impede the Cleaner's ability to move properly.
Coiled hoses are not covered under the Hayward Warranty.
Use only original Hayward spare parts and hoses to insure proper
operation.
