Section Iii. Check Valve Installation Instructions - Pentair 99101100 Owner's Manual

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.
SECTION III. CHECK VALVE INSTALLATION INSTRUCTIONS
THIS FILTER OPERATES UNDER HIGH PRESSURE. WHEN ANY PART OF THE
CIRCULATING SYSTEM (e.g., LOCK RING, PUMP, FILTER, VALVES, ETC.) IS
SERVICED, AIR CAN ENTER THE SYSTEM AND BECOME PRESSURIZED.
PRESSURIZED AIR CAN CAUSE THE LID TO BE BLOWN OFF WHICH CAN RESULT IN
SEVERE INJURY, DEATH, OR PROPERTY DAMAGE. TO AVOID THIS POTENTIAL
HAZARD, FOLLOW THESE INSTRUCTIONS.
1. BEFORE REPOSITIONING VALVES AND BEFORE BEGINNING THE ASSEMBLY,
2. WHENEVER INSTALLING THE FILTER LOCK RING FOLLOW THE CLEANING
3. ONCE SERVICE ON THE CIRCULATING SYSTEM IS COMPLETE FOLLOW INITIAL
4. MAINTAIN CIRCULATION SYSTEM PROPERLY. REPLACE WORN OR DAMAGED
5. BE SURE THAT THE FILTER IS PROPERLY MOUNTED AND POSITIONED
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.
