SECTION III. CHECK VALVE INSTALLATION INSTRUCTIONS
A. INSTALLATION
1. Turn the pump off, shut off any automatic controls to assure that the system is not inadvertently
started during servicing.
2. Open the High Flow™ manual air relief valve.
3. Plug the suction line by inserting a rag into the skimmer port, or if equipped with a valve close it at
this time to prevent water from siphoning from the pool during servicing.
4. If possible, plug the return line to prevent siphoning. If this can not be done, disconnect the union
fitting from the outlet port of the filter and quickly place the return hose into the pool.
5. Remove the drain cap to empty the water from the filter.
Failure to operate your filter system or inadequate filtration can cause poor water clarity obstructing
visibility in your pool. Poor water clarity may obscure objects in the water which while swimming and
diving could cause severe personal injury and death. Never swim in a pool with poor water clarity.
