SETUP INSTRUCTIONS
Be sure you have access to water to fill the pool and chemicals for the water.
IMPORTANT: This filter pump is shipped with the air release valve (1) open (open the air
release valve if necessary). DO NOT replace the air release valve until you reach STEP #8.
Failure to follow these instructions will result in air trapped inside filter housing; the motor
will run dry, be noisy and malfunction.
1. Assemble above-ground-pool first. Carefully follow the pool’s installation instructions.
2. Place the filter pump the length of the hose away from the pool wall where the lower black
protruding hose connection is "sticking-out". Ensure the filter pump is accessible at all time for
service and maintenance.
3. Insert the nozzle union (9 & 10) into the upper protruding hose connections. Then insert the
strainer union (9 & 11) into the lower protruding hose connections. The hoses (8) fit over the
strainers inserted into the connections.
4. There are two hoses to be connected to the filter pump hose connections. With hose clamps (7),
fasten one of the hoses (8) to the lower protruding hose connection (marked "+" on the pool
liner) and to the upper pump connection (marked "+").
5. Connect the second hose to the remaining upper protruding hose connection and to the
lower pump connection. Make sure all the hose clamps (7) are tight.
6. In a counter-clockwise motion unscrew the threaded filter housing collar (12) from the filter
housing. Grasp and remove the threaded cover (3). Check to see if a cartridge is inside the
housing. If yes, replace the cover, finger tighten the housing collar (12) back onto the filter
housing.
7. Fill the pool to a level of at least 1-2 inches above the top connection. The water will
automatically flow down into the pump.
8. When water starts flowing out of the air release valve hole, screw in the air release valve back
into the filter housing cover. Do not over tighten the valve. NOTE: Venting the system is
necessary for air to escape as the filter housing fills with water.
9. Connect the filter pump to the power outlet. The filter pump is now filtering the water.
10. Operate the filter pump until the desired water clarity is obtained.
NOTE:
Never put pool chemicals directly into the filter pump. This may damage the pump
and void the warranty.
WARNING
Risk of electric shock. Connect this product only to a grounding type
receptacle protected by a ground-fault circuit interrupter (GFCI) or
residual current device (RCD). Contact a qualified electrician if you
cannot verify that the receptacle is protected by a GFCI/RCD. Use a
qualified electrician to install the GFCI/RCD, which has a maximum rate
of 30mA. Do not use a portable residual current device (PRCD).

SETUP INSTRUCTIONS (continued)
It is essential to change any damaged element or set of elements as soon as possible. Use
only parts approved by the manufacturer.
To inspect and change the filter cartridge, disconnect line cord, unscrew the pool inlet nozzle (10)
and strainer grid (11) from the strainer connectors and insert the hat-like plugs into the strainer
connectors before servicing the filter. After service, open the air release valve, remove the plugs,
allow any air to escape through the valve before tightening the valve again and replace the pool
inlet nozzle (10) and strain grid (11). The pump is now primed with water again and may be
turned on.

FILTER PUMP STATIONARY MOUNTING OPTION
There are three mounting holes located at the bottom of the filter pump base. These holes are
provided because various country’s regulations, especially in the European community, require the
filter pump to be secured to the ground or to a base in a permanent upright position.
These three holes form a triangle pattern and are 135mm from each other. The holes are slotted with
a 7mm width.
The filter pump can be mounted on a cement base or onto a wooden structure to prevent
accidental falling over. Total assembly must exceed 18kg. The drawings on the following show two
possible ways of upright mounting.

It is recommended that the filter cartridge be replaced at least every 2 weeks.
Regularly monitor the filter clogging level.
1. Make sure filter pump is not operating. Disconnect line cord.
2. To prevent water from escaping the pool, unscrew the pool inlet nozzle (10) and strainer grid
(11) from the strainer connectors and insert the hat-like plugs into the strainer connectors.
3. In a counter-clockwise motion, remove the filter housing collar (12) and threaded cover (3). Be
careful not to lose the cover seal (4).
4. Remove filter cartridge (5) to clean it. The filter may be cleaned from the spray from a water
hose.
5. Use judgement as to whether cartridge needs to be replaced. Only use the original Intex
cartridge for replacement. See “Parts Reference” section for detail.
6. Return cartridge to filtering position.
7. Return the seal (4) and threaded cover (3) to their original positions and in a clockwise direction
rescrew the housing collar (12) onto the filter housing.
8. After service, open the air release valve, remove the plugs, allow any air to escape through the
valve before tightening the valve again and replace the pool inlet nozzle (10) and strainer grid (11).
The pump is now primed with water again and may be turned on.
9. Check the inlet and outlet openings regularly to ensure they are not obstructed thus preventing
a good filtration.
10. The disposal of any used filter media should be in accordance with applicable local regulation
and legislation.

POOL CARE AND CHEMICALS
• All pools require care to keep the water clear and hygienically clean. With proper chemical
control, your filter will help attain this objective. Consult your pool supply dealer for
instructions regarding the proper use of chlorine, algaecide and other chemical agents
required for sparkling clear water.
• Keep pool chemicals away from children.
• Do not replenish chemicals in pool while pool is occupied. Skin or eye irritations could occur.
• Daily pH checking and chemical treatment of the water is very important and can not be
overemphasized. Chlorine, algaecide and maintenance of proper pH levels are required
when filling the pool as well as during the season. Consult your local swimming pool supply
store for instructions.
• The season's first filling of the pool may have brackish water requiring extra water additives
and extra filter changes. Do not allow swimming in pool until the pH level is balanced.
Consult your local swimming pool supply store for instructions.
• Keep spare filter cartridges on hand. Replace cartridges every two weeks.
• Chlorinated water may damage lawns, gardens or shrubbery as children play in the pool and
splash water outside the pool. Lawn areas underneath the pool liner will be destroyed. Note
that some types of grass may grow through the liner.
• Filter run time depends on pool size, weather and usage level. Experiment with various run
times so as to produce clean clear water.
• European standard EN16713-3 lists some additional pool water quality and water treatment
information that can be found at www.intexcorp.com/support.
CAUTION
Concentrated chlorine solutions may damage the pool liner. Always follow
the chemical manufacturer’s directions, and the health and hazard warnings.

1. Before emptying your pool for long term storage, or relocation, be sure the water is directed
towards an acceptable drain water receptacle away from the house. Check local regulations
for specific directions regarding disposal of swimming pool water.
2. Now, drain the pool.
3. When the pool is empty, disconnect all pool hoses (8) from the pool and filter pump, simply
reverse the set up instructions.
4. Remove the filter cartridge as shown in the Filter Cartridge Cleaning section, steps 2 thru 4.
5. Remove the nozzle and strainer unions from the pool wall. Place the wall plugs into the hose
connections. Loosen clamps (7) securing the strainer connectors (9) before removal.
6. Drain water from the filter pump housing.
7. Leave filter pump pieces and hoses outside to thoroughly air dry.
8. Depending on the cartridge (5) usage, a new cartridge may be needed for next season, keep
a spare available.
9. Cover the seal (4), air release valve O-ring (2) and hose seals (6) with petroleum jelly to
preserve its resilience during storage.
10. Store the unit and accessories in a dry place. The storage's temperature should be
controlled, between 32 degrees Fahrenheit (0 degrees Celsius) and 104 degrees Fahrenheit
(40 degrees Celsius) storage location.
11. The original packing can be used for storage.
