VACUUMING THE POOL
Light Soil: set the control valve to FILTER position.
Heavy Soil: set the control valve to WASTE position.
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 the
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.
TROUBLE SHOOTING
SAND BACK TO POOL
Sand too small; Flow too high; Sand bed calcified;
Broken Laterals; Loose centre-pipe; Too much sand;
Control Valve not engaged; Air accumulation in filter.
SAND OUT OF BACKWASH HOSE
Flow too high; Too much sand in tank.
INADEQUATE FILTERING
Dirty make-up water; improper sand; Sand is too low;
Algae in filter; Excessive dirt in pool; Calcified sand
bed; Heavy swimmer load; Flow rate too high or too
low; Backwashing cycle too short; Backwash line too
small.
SHORT FILTER CYCLE
Dirty filter; Improper sand; Sand is low; Algae in filter;
Excessive dirt in pool; Calcified sand bed; heavy
swimmer load; Flow rate too high or too low;
B a c k w a s h i n g c y c l e t o o s h o r t ; C h a n n e l s l o w ;
Backwash adapter in wrong location; Channels in
sand.
FILTER LEAKS
Tank cracked; Drain plug not tight; Valve/Tank O'ring
damaged.
CONTROL VALVE LEAKS
Handle not properly engaged; Valve/Tank O'ring
damaged; Valve cover O'ring damaged. Pressure
gauge O'ring damaged.
ABNORMAL LOSS OF POOL WATER
Leak inside Control Valve; Leakage from pool or
piping.
HIGH PRESSURE FILTER
Dirty filter; Calcified sand bed; Return lines too small.
LOW PRESSURE IN FILTER
Control Valve incorrectly set; Pump running too slow
(plugged or clogged); Air leakage into pump suction.
NOTE:
If the recommendation in this manual do not
solve your particular problem(s), please contact
your local dealer for service.

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. Secure using
the screw provided.
10/ Firmly tap with a rubber mallet outside of the
clamps as you tighten the screw.
11/ Install the Multiport Control Valve to the filter. Make
sure the unions of inlet and outlet are 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.
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.
