INSTALLATION
* Install filtration system including pump,
filter tank and multiport valve.
* The filter system should be installed as close as possib
l
e to the swimming pool and preferably at a
minimum
level of
2 feet
below the surface of the water in the swimming pool.
Make sure there is drainage available at the
location
where the filter
will
be installed.
PUMP
1.
Only qualified,
licensed personnel should install pump and wiring.
2.

LEASE
NOTE
:
All 115 volt 60Hz pump must be wired to the main power
supply, by a licensed professional.
3.
Allow for gate valve in suction piping.
4.
Pump suction and discharge connections have moulded in thread stops,do not try to screw pipe in
beyond these stops.
FILTER TANK and MULTIPORT VALVE
1.
Loading the sand media.
Filter sand media is loaded through the top opening of the filter.
a.
Loosen the plastic clamps from tank neck.
b.
Cap internal pipe with plastic cap to prevent sand from entering it.
c.
We recommend filling tank approximately 1/2 way with water to provide a cushion effect when the
filter sand is poured in. This helps protect the under-drain laterals from excessive shock.
d.
Carefully pour in correct amount and grade of filter sand.
Be sure center pipe remains centered in opening.
Sand surface should be leveled and should come to about the middle of the filter tank.Remove plastic cap
from internal pipe.
2.
Assemble filter
multi-port
valve to filter tank.
a.
Insert filter
multi-port
valve
(with O'ring in place)
into the tank neck,
taking care that the center pipe slips
into the hole in the bottom of the valve.
b.
Place two plastic clamps around valve flange and tank neck and tighten just enough so
that the valve may
b
e rotated on tank for final positioning.
c.
Carefully screw pressure gauge
(with O'ring in place)
into tapped hole in valve body.
Do not over-tighten.
d.
Connect pump to control valve opening marked PUMP with hose.
After connections are made,
tighten clamps with screwdrive

3.Make return to pool pipe connection to
multi-
port
valve opening marked RETURN and complete other
necessary plumbing connections,
suction lines to pump,waste,etc.
4.To prevent water leakage,be sure all pipe connections are tight.
1. Be sure correct amount of filter media sand is in tank and that all connections have been made and are secure.
2. Depress
multi-filter
valve handle and rotate to BACKWASH position. (To prevent damage to
multi-
port
valve seal,
always depress handle before turning.)
3. Prime and start pump. Never
r
un pump dry! Running pump dry may damage seals,
causing leakage and flooding!
Fill pump with water before starting motor.
B
e sure all suction and return lines are open, allowing the filter tank
to fill with water. Once water is flowing out of the waste line, run the pump for at least 1 minute. The initial
back-washing of the filter is recommended to remove any impurities or fine sand particles in the sand media.
4. Turn pump off and set valve to RINSE position. Start pump and operate until water in sight glass is clear, about
normal filter mode, filtering dirt particles from the pool water.
5. Adjust pool suction and return valves to achieve desired flow. Check system and filter for water leaks and tighten
6. Note the initial pressure gauge reading when the filter is clean. (It will vary from pool to pool depending upon the

filter will cause the pressure to rise and flow to diminish. When the pressure gauge reading is

higher than the initial "clean" pressure you noted, it is time to backwash the filter (see BACKWASH under
multi-filter
valve functions).
