INSTALLATION
Installation had been made simple, the only tools
needed is a screwdriver and pipe sealant for plastic.
The filter should be installed as close to the pool as
possible, but keep a distance of at least 5 feet
(1.5m). Locate the Filter on rigid, level surface,
preferably in a dry, shaded, and well-ventilated
area. Prior to installation give consideration to the
following: Position of suction, return, and waste
connections. Access for backwashing operation
and servicing; protection from sun, rain, splashing,

protection of the motor.
1)Place the empty tank in position.
2)Fill the tank with water to the level that covers the
laterals (crepinas), or about 1/3 of the tank height
is recommended. This will avoid damages to the
laterals (crepinas) by the force of the sand when
pouring into the filter.
Model MFV17, the Multiport Control Valve had been
pre-assembled. Remove the Multiport Control Valve
from the tank by unfastening the screw from the
Clamp. Place the Sand Fill Cover over the tank
opening to prevent the sand from getting into the
standpipe.

HOW IT WORKS
The Filter uses special sand to remove dirt particles
from pool water. Filter sand is loaded into the filter
tank to act as the filtration media. The pool water
which contains dirt particles is pumped through your
piping system to the filter via the filter control valve.
As pool water passes through the filter, dirt particles
will be caught by the sand bed and filtered out. The
cleaned pool water is returned from the bottom of
the Filter Tank, through the control valve and back to
the pool through your piping system. The entire
process is continuous and automatic. It is this process
that provides the filtration and circulation of water in
your pool.
With the filtration process, dirt will accumulate and
becomes saturated in the filter tank. Pressure in the
tank will increase and the resistance of water flow
will occur. This means it is time to clean (backwash)
your filter. Another indication to know when to clean
(backwash) the filter is by checking the pressure
gauge reading. Backwash operation should be
performed when the pressure increases by 10psi
above the pressure when it was clean. Typically a
clean filter will run at 10 to 15psi, so take note of the
pressure gauge reading when the filter was installed.
When the pressure reaches approximately 20 to
25psi or 50% increase from the clean reading,
proceed to the Backwash operation.
WARNING: turn off the pump before switching the
control valve handle.
To perform the Backwash operation, position the
handle on the control valve to “Backwash”, the
water flow is automatically reversed through the
filter so the water is directed from the bottom of the
tank, up through the sand, flushing the trapped dirt
