OPERATING INSTRUCTION

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).
• To reduce the risk of electric shock, do not use extension cords, timers, plug adaptors or converter plugs to connect unit to electric supply; provide a properly located outlet.
• Do not attempt to plug in or unplug this product while standing in water or when your hands are wet.
• Never operate this product above the maximum working pressure stated on the filter tank.
• Always switch off pump before changing the 4-way valve position.
• Operating this product without water flowing through the system can cause a build up of hazardous pressure which can result in an explosive situation, serious injury, property damage or death.
• Never test this pump with compressed air. Never operate the system with water temperature above 35°C (95°F).

4-way valve positions and function:

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).

1. Release air from the system – Ensure the drain/waste outlet on the 4-way valve is not covered and directed to a proper draining receptacle, and the pump is off. Turn the 4-way valve to the “N” position and unscrew the air release valve (14) from the motor housing (see drawing 18). When water starts flowing out of the air release valve hole, close the air release valve back.

2. BACKWASH – Ensure the pump is off, depress the 4-way valve and turn it to the “BACKWASH” position (see drawings 15 & 19).

IMPORTANT: To prevent damage to the 4-way valve, always depress the valve handle before turning. Always switch off pump before changing the 4-way valve position.

3. 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.

4. Switch off the pump, change the 4-way valve to “FILTER” position (see drawing 14).
5. 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.

6. Record the initial pressure gauge reading when the filter media is clean.

NOTE: Duririg 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. lntex 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.

7. 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.

2. 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.

3. Lock keypad controls:
(1 to 12 hours max per cycle) 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.

4. 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.

5. 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):

1. 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.

NON INTEX POOLS TIME TABLE

This table shows the required operating time for average use of the sand filter pump with above ground pools.

POOL CARE AND CHEMICAL

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

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

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. Switch off the unit, and disconnect power cord from electrical outlet.
3. When the pool is empty, disconnect all hoses from pump and remove the strainers from the pool wall.
4. 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.
5. Disassemble the pump motor from the tank base.
6. Leave sand filter pump pieces and hoses outside to thoroughly air dry.
7. Coat the following o-rings with petroleum jelly for long term storage:

• Hose o-rings (6).
• Air release valve a-ring (15).

8. Depress the 4-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 4-way valve in this inactive position.
9. 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.
10. Store the pump motor and accessories in a dry place. The storage’s temperature should be controlled, between O degrees Celsius (32 degrees Fahrenheit) and 40 degrees Celsius (104 degrees Fahrenheit).
11. Cover the tank with a tarpaulin or plastic sheet to protect it from the weather.
