Your Emaux “Filter Max” Filter is a high performance corrosion-proof filter that has superior flow characteristics that is with the
ease of operation. Everything is made simple from installation, operation to the maintenance of the filter. Your “Filter Max”
filter will be your pool filtration partner that provides clear water with the least maintenance hassle and care.
WARNING: BEFORE INSTALLATION BE SURE TO READ ALL INSTRUCTIONS AND WARNINGS
CAREFULLY. KEEP THIS USER MANUAL FOR FUTURE REFERENCE.
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 and debris
out of the waste line. The duration of the backwash operation will depends on how dirty your filter is. Check the
sight glass to see when the water becomes clear. It is recommended that the backwash should be at least 2
minutes long.
Once the backwash operation had been completed, the filter should go through the process of “Rinse” and
then back to “Filter”. To perform the different operations, position the handle on the control valve as indicated.

1. Place on tank
opening. 2. Add water to
cover laterals
and add sand.
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, etc; Drainage of filter room; Ventilation and protection
of the motor.
1)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.

2)Pour the recommended amount of sand into the tank, making sure
that the centre-pipe remains centred and vertical.
3) Level the surface of the sand upon completion.
4)Remove the Sand Fill Cover.
5)Carefully remove all sand particles from the valve mounting
surface.
6)Place the O-ring into the groove on the tank.
7)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.
8)Place the clamp set around the tank and the valve. Secure using
the screw provided.
9)Firmly tap with a rubber mallet outside of the clamps as you
tighten the screw.
10)Tighten the screw until the Multiport Control Valve is properly
assembled to create a water tight seal. Do not over tighten.
11)Install the pressure gauge into the threaded opening on the Multiport Control
Valve.
12)Install the union sets and the backwash union set.
13)Connect pump to the control valve opening marked “PUMP”.
14)Make return to pool pipe connection to control valve opening marked
“RETURN”.
15)Connect the waste water pipe to the control valve opening marked “WASTE”.
16)To prevent water leakage, be sure all pipe connections are tight.
17)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.

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.
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.
