10. Tighten clamp screws firmly and visually check
the valve tank and clamp assembly to insure that
the joint is correctly assembled.
11. The filter unit has a maximum operating pressure list-
ed on the filter name plate. DO NOT OPERATE
this unit above the maximum operating pressure
of the valve or the filter. Never connect the filter and
valve unit to a pump which can generate a pressure
that exceeds the operating pressure of the filter or
valve.
12. Use sealant on all tapered male connections of pipe
and fittings. Use only sealant compounds suited for
plastic pipe. Support pipe to prevent strains on filter,
pump or valve. DO NOT USE PETROLEUM
BASED PRODUCTS. NOTICE: All valve
Internal threads are tapered except the air bleed-
er connection. Do not over tighten tapered thread
connections.
13. Install pressure gauge in 1/4” NPT port directly
across from the pump port of the valve.
14. Never store pool chemicals within 10 feet of your
pool filter, pump or valve. Pool chemicals should
always be stored in a cool, dry, well ventilated area.
WARNING
Improper tank valve assembly could cause the valve to blow off
and cause severe injury and/or property damage.

WARNING
Chemical fumes and/or spills can cause severe corrosive attack
to the filter and pump structural components. Structurally
weakened components can cause filter, pump or valve attach-
ments to blow off and could cause severe bodily injury or
property damage.

15. Avoid over tightening the pipe threads when connect-
ing fittings to the pump or valve. Proper procedure is
to apply a pipe sealant to the thread and then install
hand tight plus 1 turn. DO NOT OVER TIGHTEN.
Section III. Initial Start Up.
1. Be sure the correct amount of Silica filter sand
is in the tank and that all connections have been made
and are secure.
2. Check that the backwash is open so that water
is free to flow from the pool and out the backwash
line. Set the control valve to Backwash position.
3. Stand clear of the filter. Prime and start pump
according to the pump instructions allowing the filter
tank to fill with water. Once the water flow is steady
out of the waste line, run the pump for at least two
minutes. This initial backwashing of the filter is rec-
ommended to remove any impurities of fine sand par-
ticles in the Silica sand media.
4. Turn the pump off and set valve to rinse posi-
tion. Ensure that all pool suction and return lines are
open so that the water is free to flow from the pool to
waste. Stand clear of filter and start the pump.
WARNING
The system's centrifugal pump operates with electrical volt-
age, and can generate both vacuum and pressure in the
water system. When properly wired and plumbed, this pump
will operate in a safe manner.

WARNING
Hazardous voltage - can cause severe or fatal injury. Always
install a suitable GFCI at the power source of this unit as an
added safety precaution. Article 680-31 of the NEC requires
that a GFCI be used if this pump is used with storable pools.

WARNING
▲
!
This filter operates under pressure. With the
valve clamped properly and operated without air
in the system, this filter will operate in a safe
manner. Air entering the filter and the valve not
clamped correctly can cause the valve to be
blown off, which could cause severe personal
injury and/or property damage.
CAUTION
Always turn pump off before changing valve positions.
Changing valve positions while the pump is running can
damage the control valve, which may cause personal
injury or property damage.
