housing. If yes, replace the cover, finger tighten the housing collar (1) back onto the filter
housing.
7. Gently finger tighten the sediment release valve located at the bottom of the housing to be
sure that water does not leak out.
8. When the pool is filled connect the hose from the bottom of the filter housing to the highest
strainer assembly. You will find the hose connection at the bottom of the plunger valve
assembly. Use the hose nut to attach the hose.
9. Connect the second hose which is fixed to the middle of the motor housing to the remaining
liner connection.
It is essential to change any damaged element or set of elements as soon as possible.
Use only parts approved by the manufacturer.

FILTER PUMP STATIONARY MOUNTING
Some countries, especially in the European community, require the filter pump to be secured to
the ground or to a base in a permanent upright position. Check your local authorities to determine
if there is a regulation in your area regarding above-the-ground swimming pool filter pumps. If yes,
then the filter pump can be mounted to a platform using the two holes located in the base. See
drawing below.
The filter pump can be mounted on a cement base or onto a wooden platform to prevent accidental
falling over. Total assembly must exceed 18kg.
165 mm
1. The mounting holes are 6.4 mm in diameter and spaced 165 mm apart.
2. Use two bolts and lock nuts with a maximum of 6.4 mm in diameter.
FILTER PUMP INSTALLATION DISTANCE

CLEANING OR REPLACING FILTER CARTRIDGE
It is recommended that the filter cartridge be replaced at least every 2 weeks or as
needed. Regularly monitor the filter clogging level.
The filter pump is equipped with a filter gauge, which indicates when to
clean or replace the filter cartridge:
• Green zone: the filter cartridge is clean, no need to clean or replace.
• Yellow zone: the filter cartridge is dirty; it needs to be cleaned.
• Red zone: the filter cartridge is excessively dirty; it shall be cleaned or
replaced.
NOTE: To ensure a correct filter gauge reading, remove any accessories
(skimmer, lights, sprayer, auto cleaner, etc) from the filtration system inlet
and outlet line. See “Troubleshooting Guide” section for details.
When the pump is not running (stand by mode) or OFF, the filter gauge indicator is in the green
zone. You must activate the filter pump to see the last filter gauge indicator status.
The following steps provide instructions on how to clean or replace the filter cartridge.
1. Make sure the filter pump is turned off, then disconnect the power cord from the electrical
outlet.
2. Turn both plunger valve handles fully clockwise until they stop. This closes the valve,
prevents the water from flowing out of the pool.
3. Gently turn the top air release valve once or twice in a counter-clockwise direction. The
housing cover can now be easily removed.
4. In a counter-clockwise direction remove the filter housing collar (1). Place it in a safe
location.
5. Remove the housing cover (4).
6. Remove the used filter cartridge and use a strong pressure garden hose to rinse it clean.
Replace with a new filter cartridge when it is discolored, deformed, has small holes and tears
or as needed.
7. Examine the inside of the filter housing.
8. If dirt or sediment is located on the bottom of the housing then:
A. In a counter-clockwise motion gently unscrew and remove the sediment valve (9)
located at the bottom of the housing. Place it in a safe place.
B. With a bucket of water or a garden hose pour water into the housing flushing out the
sediment.
C. Screw back the sediment valve (9) in a gentle clockwise motion. Do not over-tighten.
9. Place a clean or new cartridge filter in the housing. Only use the original Intex cartridge for
replacement. See “Parts Reference” section for detail.
10. Return the housing cover (4) to its position and in a clockwise direction rescrew the housing
collar (1) onto the filter housing.
11. Turn both plunger valve handles fully counter-clockwise until they stop. This opens the
valve, allowing water to flow into the filter pump.
12. When the trapped air has escaped through the air release valves gently retighten the valves
(2 & 7) in a clockwise direction.

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. Disconnect power cord from electrical outlet.
3. Now, drain the pool.
4. When the pool is empty, disconnect all hoses from pump and plunger valves and remove
the strainers from the pool wall.
5. Drain all water from the filter pump.
6. Leave filter pump pieces & hoses outside to thoroughly air dry.
7. Remove both plunger valves from the connectors
(14 & 19) . Be careful not to lose the step
rubber washer (22).
8. Coat the following O-rings and washers with petroleum jelly for long term storage:
• Air release valve & sediment O-rings (3 & 11).
• Filter housing cover O-ring (5).
• Pump hose O-rings (21).
• Strainer valve assembly step washers (22).
• Flat strainer rubber washers (13).
9. Discard the used filter cartridge. Put aside 1 or 2 new cartridges for next season’s use.
10. It is best to place all dry pieces in the original packaging for storage or place them in an
airtight plastic bag.
11. 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.

Water recreation is both fun and therapeutic. However, it involves inherent risks of injury and death.
To reduce your risk of injury, read and follow all product, package and package insert warnings and
instructions. Remember, however, that product warnings, instructions and safety guidelines cover
some common risks of water recreation, but do not cover all risks and or dangers.
For additional safeguards, also familiarize yourself with the following general guidelines as well as
guidelines provided by nationally recognized Safety Organizations:
• Demand constant supervision. A competent adult should be appointed as a “lifeguard” or water watcher,
especially when children are in and around the pool.
• Learn to swim.
• Take the time to learn CPR and first aid.
• Instruct anyone who is supervising pool users about potential pool hazards and about the use of protective
devices such as locked doors, barriers, etc.
• Instruct all pool users, including children what to do in case of an emergency.
• Always use common sense and good judgement when enjoying any water activity.
• Supervise, supervise, supervise.
