Provide a location protected from the weather, moisture, flooding and freezing temperature.
Provide adequate access, space and lighting for routine maintenance.
The pump motor requires free circulation of air for cooling. Do not install the pump in a damp or non-ventilated location.
A team of 2 or more people is recommended for setting up this product.
The appliance is intended only for household use.

Leaf trap setup:

Make sure the pump o-ring (6) is in place. In a clockwise motion screw the leaf trap (19) onto the motor inlet (see drawing 10).

Sand tank installation:

Place the tank support base at the selected location.
Place the tank on the tank support base (see drawing 11.1).
In a clockwise motion screw the center pipe (7) onto the filter grid (8) securely by hand (see drawing 11.2).
Vertically insert the filter grid and center pipe assembly into the tank. Ensure filter grid assembly is securely fitted to the bottom of the tank, and the center pipe is vertically centered inside the tank (see drawing 11.3).

Sand loading

IMPORTANT: Use No. 20 silica sand or glass sand with a particle size range of 0.45 to 0.85 mm (0.018 to 0.033 inches) and a Uniformity Coefficient less than 1.75. Only use the filter media specified by the manufacturer.
NOTE: Before loading the tank with sand, ensure the sand filter grid and center pipe assembly is securely in place on the tank bottom, and the center pipe (7) is vertically centered inside the tank.

To prevent sand from falling into the center pipe top opening when pouring the sand, cover the center pipe top opening with a cup or similar object (see drawing 12).
With one person holding the center pipe to keep it centered, pour the sand into the tank at a slow rate manually to prevent the filter grid assembly from shifting (see drawing 13).
Fill the tank approximately half way first to evenly distribute the sand inside the tank, then fill the tank with some water to provide a cushioning effect when the remaining sand is poured in. This prevents the filter grid (8) from excessive shock (see drawing 14).
Sand shall be filled between the “MAX” and “MIN” marked gauge on the center pipe. Evenly spread and level out the sand by hand (see drawings 14 & 15).
Remove the protective cup from the center pipe top opening.
Wash away all sand around the top edge of the tank.

IMPORTANT: Ensure the center pipe (7) remains centered after sand loading is completed before proceeding to the next step.

WARNING: Improper tank valve and clamp assembly could cause the valve and clamp to blow off and cause serious injury, property damage or death.

6-way valve installation:

Make sure the tank o-ring (5) is in place (see drawing 16). NOTE: Ensure the tank o-ring is free of sand or debris.

Control panel description INTex-SF90220RC-1-4-m³-Krystal-Clear-Sand-
Filter-Pump-FIG-32

Initial startup and operation: Before operating, be sure that:

All the hoses have been connected and tightened securely, and correct amount of filter sand have been loaded.
The entire system is connected to a grounding type receptacle protected by a ground-fault circuit interrupter (GFCI) or residual current device (RCD).

CAUTION

The filter control valve has a closed position. The pump should never be on when the valve is in the closed position. If the pump is operated with the valve closed, explosive situation could exist.

Turn both plunger valve handles fully counter-clockwise until they stop. This opens the valves to allow water to flow into the sand filter pump.
Release air from the system – Ensure the drain/waste outlet on the 6-way valve is not covered and directed to a proper draining receptacle, and the pump is off. Turn the 6-way valve to the “N” 36 position and unscrew the air release valve (36) from the motor housing (see drawing 29). When water starts flowing out of the air release valve hole, close the air release valve back.
BACKWASH – Ensure the pump is off, depress the 6-way valve 1 and turn it to the “BACKWASH” position (see drawings 24 & 30).
IMPORTANT: To prevent damage to the 6-way valve, always depress the valve handle before turning. Always switch off pump before changing the 6-way valve position. 2
Press to switch on the system, and then press to set the operating TIMER hours (see “Operating the system under TIMER mode or manually” section for details). Water is circulating backward through the sand media and to waste/drain outlet. Backwash until a clear flow of water is observed in the waste/drain outlet.
NOTE: If the LED display flashes “00”, the device is in stand-by mode and the pump will not operate. The initial backwash of the filter is recommended to remove any impurities or fine sand particles in the sand media.
Switch off the pump, change the 6-way valve to “RINSE” position (see drawing 25).
Switch on the pump and run the pump for about one minute to level out the sand bed after backwashing the sand media.
Switch off the pump, change the 6-way valve to “FILTER” position (see drawing 23).
Switch on the pump. The system is now operating in the normal filtering mode. Run the pump until the desired pool water clearance is obtained and no more than 12 hours per day. For the initial startup, it is recommended setting the system to a longer TIMER operating hours or “FP” for the pump to operate continuously without the TIMER.
Record the initial pressure gauge reading when the filter media is clean.
NOTE: During initial setup of the system, it may be necessary to backwash frequently due to unusual heavy dirt present in the water and sand. After that, as the filter removes dirt and impurities from the pool water, the accumulated dirt in the sand media will cause the pressure to rise and the flow to diminish. If there is no vacuuming device attached to the system and the pressure gauge reading is in the yellow zone it is time to backwash the sand media, see “BACKWASH” under “initial startup and operation” section.
Vacuuming device (i.e. Intex auto pool cleaner) attached to the system may also cause the flow to diminish and the pressure to rise. Remove any vacuuming device from the system and check if the pressure gauge reading has dropped from the yellow zone to the green zone.
Monitor the pressure gauge reading, and check that the inlet and outlet openings are not obstructed on a weekly basis. If the pressure gauge indicates yellow it is time to backwash the filter media.

Operating the system under “TIMER” mode or manually

To operate the sand filter pump in “FILTER” mode under “TIMER” control: 1. Activate the unit:

Press button Flashing code “00” appears on the LED display, indicating that the unit is ready to be programmed.
Set operating hours: With code “00” flashing, press button to set the desired operating hours. See the “Operating Time Table” for the required operating hours related to each pool size. Pressing will increase the time from 01 to 12 hours maximum. If you have selected too many hours keep pressing to repeat the cycle. The built-in timer will now activate the Sand filter pump, at the same time each day, for the number of hours you have set.
Lock keypad controls: With the desired hour value showing, press button until you hear a “beep”. Locking the control buttons into this setting prevents unauthorized changing of the operating cycle.
- NOTE: If you forget to lock the keypad controls, the system will automatically lock it and start working 10 seconds later The sand filter pump is now filtering the water and will stop after the operating hours are completed.
Readjust operating time if necessary: The operating hours can be re-adjusted if necessary. Press button until you hear a “beep” to unlock the keypad and the current programmed time will flash. Repeat steps 2 to 3.
Stand-by/power saving mode:
- When the cycle ends, the LED display shows “00”. The system is now in Stand-By mode. After 5 minutes the system goes into Power Saving mode and the LED display shows “.”. The system will automatically turn itself back on in 24 hours.
- While the system is in Power Saving mode, press any button and the system will briefly display the programmed time and then “00”.
- To view the TIMER preset hours: While the pump is operating, press “ ” button, the display will briefly flash the preset hours for 10 seconds and then display back the remaining operating hours.

To operate the sand filter pump manually (without the “TIMER” mode):

to run the pump alone without the “Timer”, press button to turn on the pump, then press button until the LED displays “FP”, this indicates that the TIMER is off and the pump is now operating continuously.

FIG-35

POOL CARE & 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 cannot 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 filtering time. Do not allow swimming in pool until the pH level is balanced. Consult your local swimming pool supply store for instructions.
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.

LONG TERM STORAGE & WINTERIZATION

CAUTION

Allowing the water to freeze will damage the sand filter and void the warranty.

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.
Switch off the unit, and disconnect power cord from electrical outlet.
When the pool is empty, disconnect all hoses from pump and plunger valves and remove the strainers/plunger valves from the pool wall.
In a counter clockwise motion unscrew the drain valve cap (9) from the drain valve to thoroughly drain the tank. The drain valve is located at the bottom of the filter tank.
Disassemble the pump motor from the tank base.
Leave sand filter pump pieces and hoses outside to thoroughly air dry.
Coat the following o-rings and washers with petroleum jelly for long term storage:
• L-shape o-rings (11 & 18).
• Pump hose o-rings (22).
• Strainer valve assembly step washers (23).
• Flat strainer rubber washers (25).
Depress the 6-way valve handle and rotate so as to set the pointer on the valve top “N” position. This allows the water to drain from the valve. Leave the 6-way valve in this inactive position.
It is best to place all dry pieces and pump motor in the original packaging for storage. To avoid condensation or corrosion problem, do not cover or wrap pump motor with plastic bags.
Store the pump motor and accessories in a dry place. The storage’s temperature should be controlled, between 0 degrees Celsius (32 degrees Fahrenheit) and 40 degrees Celsius
(104 degrees Fahrenheit).
Cover the tank with a tarpaulin or plastic sheet to protect it from the weather.
