Pentair STA-RITE POSI-CLEAR RP Guide De L'installation page 5

When the cartridge element filter is used on new pools and after cleaning the elements, introduce into the
system 0.25 Kg of diatomaceous earth per every 100 square feet of filter area, (a one-pound coffee can equals
0.25 Kg of diatomaceous earth). Mix the diatomite with water and pour it into the skimmer after the pump is
primed and the system is operating. This will enhance the filtration of your water.
B. LOCK RING INSTALLATION INSTRUCTIONS
These instructions MUST BE FOLLOWED EXACTLY to prevent the lid from blowing off during system restart
or later operation.
1. Perform the following steps before working on any part of the circulating system (e.g., lock ring, pump, filter,
valves, etc.).
a. Turn the pump off and shut off any automatic controls to ensure that the system is not inadvertently
started during servicing.
b. Open the High Flow™ manual air relief valve.
c. Wait until all pressure is relieved. Never attempt to assemble, disassemble or adjust the filter lock
ring while there is any pressure in the tank.
THE 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.
2. Be certain the O-ring is in position in the lower tank half. Place the filter lid over the lower tank half, making
sure it is fully and firmly seated on the tank half, see Figure 2.
3. Place lock ring over the tank lid, and centering the lock ring on the threads of the tank body. Turn the lock
ring clockwise until the safety latches click and the lock ring hits the stops on the body. DO NOT ATTEMPT
TO OVER-TIGHTEN THE LOCK RING AFTER LOCK RING HAS HIT THE STOPS ON THE BODY.
4. Follow the System Restart Instructions in Section C
C. SYSTEM RESTART INSTRUCTIONS
THE TANK SEPARATION 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. Open the High Flow™ manual air relief valve until it snaps into the full open
position (this only requires a quarter turn counterclockwise). Opening this
valve rapidly releases air trapped in the tank.
2. Stand clear of the tank, then start the pump.
3. Close the High Flow™ manual air relief valve after a steady stream of water
appears.
4. The system is not working properly if either of the following conditions occur.
a. A solid stream of water does not appear within 30 seconds, after the
pump's inlet basket fills with water.
b. The pressure gauge indicates pressure before water outflow appears.
If either condition exists, shut off the pump immediately, open valves in the
water return line to relieve pressure, and clean the air relief valve, see Section F.
