of “Rinse” and then back to “Filter”. To perform the
different operations, position the handle on the
control valve as indicated.
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,
et c; D ra i na ge o f fi lte r ro om; Ven ti lat ion and
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

WINTERRISING
Backwash the filter for at least thirty minutes before
closing down the pool for winterising. This will clean
the filter bed thoroughly.
1) Drain the filter tank by removing the drain cap at
the base of the filter tank. Leave the cap off
during winter.
2) Set the control valve handle between the RINSE
and FILTER. This will lift the handle and help with
the draining process by allowing air to enter into
the tank.
3) Unscrew the pressure gauge from the control
valve and store the gauge indoor.
4) Drain and winterise pump according to pump
instructions.
5) Repairs should be made during the off-season
when the best service is available, do not leave
them until the next season.

3 Pour the recommended amount of sand into the
tank, making sure that the centre-pipe remains
centred and vertical.
4) Level the surface of the sand upon completion.
5) Remove the Sand Fill Cover.
6) Carefully remove all sand particles from the valve
mounting surface.
7) Place the O-ring into the groove on the tank.
8) Lower the Multiport Control Valve carefully into
position so that its underside engages with the
centre-pipe. Rotate the valve until the inlet is
approximately in line with the pump.
9) Place the clamp set around the tank and the
valve. Secure using the screw provided.
10) Firmly tap with a rubber mallet outside of the
clamps as you tighten the screw.
11) Tighten the screw until the Multiport Control
Valve is properly assembled to create a water
tight seal. Do not over tighten.
) START-UP PROCEDURE
1 Be sure the correct amount of filter sand media is in
the tank and all connections have been made and
are secure.
2) Turn the Control Valve handle to the “Backwash” position.
Press the handle downward before turning.
3) Start the pump according to pump instruction manual
(be sure all suction and return lines are open).
4) Once water flow is steady out the waste line, run the
pump for at least 2 minutes. The initial backwashing
of the filter is recommended to remove any impurities
or fine sand particles in the sand media.
5) Turn the pump off and set the control valve to RINSE
position. Start pump and operate until water in sight
glass is clear about ½ to 1 minute. Turn pump off, set
valve to FILTER position and restart pump. Your filter is
now operating in the normal filter mode, filtering particles
and dirt from the pool water.
6) Take note of the initial pressure gauge reading for
future reference. Variation may occur from pool to
pool.
7) Adjust pool suction and return valves to achieve
desired flow. Check system and filter for water leaks
and tighten connections, bolts, nuts as required.
NOTE: During the initial clean-up of the pool water, it
may be necessary to backwash frequently due to the
unusually heavy initial dirt load in the water.
IMPORTANT: To prevent unnecessary strain on piping
system and control valve, always turn off the pump
before changing the operation of the control valve. To
prevent damage to the pump and filter and for proper
operation of the system, clean pump strainer (basket)
and skimmer basket(s) regularly.
MULTIPORT CONTROL VALVE FUNCTIONS:-
FILTER gives downward flow through the filter bed. This
position can also be used for vacuuming.
BACKWASH gives upward flow through the filter bed
that removes the dirt from the sand and carries it to the
waste.
WASTE is for pumping water from the pool. It allows the
flow from the pump to bypass the filter and go directly
to the waste. You can also use this position to vacuum
heavy concentration of debris.
RECIRCULATE bypasses the filter to circulate water
through the pool system.
RINSE gives a downward flow that settles the filter bed
after backwashing and carries any remaining loose dirt
to the waste.
CLOSED prevents only backflow of water from pool
during pump maintenance.
To WINTERISE, set the control valve handle in the middle
between RINSE and FILTER. This will allow air to leave or
enter the tank to help priming and draining. Only to be
used when the pump is off.
VACUUMING THE POOL
Light Soil: set the control valve to FILTER position.
Heavy Soil: set the control valve to WASTE position.
)
12 Install the pressure gauge into the threaded
opening on the Multiport Control Valve.
13) Install the union sets and the backwash union
set.
14) Connect pump to the control valve opening
marked “PUMP”.
15) Make return to pool pipe connection to
control valve opening marked “RETURN”.
16) Connect the waste water pipe to the control
valve opening marked “WASTE”.
)
17 To prevent water leakage, be sure all pipe
connections are tight.
18) Prior to starting the filtration process by turning
on the pump, we highly recommend that you
read through the pump instruction manual to
ensure proper installation and to avoid the risk
of electric shock.
