Operating Instructions

Initial Startup and Operation:

Before operating, ensure all hoses are connected and tightened, correct amount of filter sand is loaded, and the system is connected to a grounding type receptacle protected by a GFCI/RCD.

1. Turn both plunger valve handles fully counter-clockwise to open valves and allow water to flow into the sand filter pump. Water pressure will allow trapped air to escape from the air release valves (19). When water flows out, gently finger tighten the valves (19) clockwise.

   IMPORTANT: To prevent air lock, open the lower plunger valve (connected inlet hose) first, then the upper plunger valve (connected outlet hose). Open air release valves, wait until water flows out, then close them.

2. Ensure the drain/waste outlet on the 6-way valve is not covered and directed to a proper draining receptacle.
3. BACKWASH: Ensure pump is off, depress the 6-way valve and turn it to the “BACKWASH" position. Always depress the valve handle before turning. Always switch off pump before changing the 6-way valve position. Press the ON/OFF button to switch on the system, and then press the TIMER button to set operating hours. Water circulates backward through sand media to waste/drain outlet. Backwash until clear water is observed.

   NOTE: If LED display flashes "00", device is in stand-by mode. Initial backwash is recommended to remove impurities or fine sand particles.

4. Switch off pump, change 6-way valve to “RINSE” position.
5. Switch on pump and run for about one minute to level out sand bed after backwashing.
6. Switch off pump, change 6-way valve to “FILTER” position.
7. Switch on pump. System operates in normal filtering mode. Run pump until desired pool water clearance is obtained (no more than 12 hours per day). For initial startup, set to longer TIMER operating hours or "FP" for continuous operation.
8. Record initial pressure gauge reading when filter media is clean.

   NOTE: During initial setup, frequent backwash may be necessary due to heavy dirt. As filter removes dirt, pressure will rise and flow diminish. If pressure gauge reading is in the yellow zone, backwash the sand media. If a vacuuming device is attached, remove it and check if pressure drops to green zone.

9. Monitor pressure gauge reading and check inlet/outlet openings weekly. If pressure gauge indicates yellow, backwash filter media.

Operating the System under "TIMER" Mode or Manually:

To operate in "TIMER" mode:

1. Activate unit: Press ON/OFF button. Flashing "00" appears on LED display.
2. Set operating hours: With "00" flashing, press TIMER button to set desired operating hours (1 to 12 hours max per cycle). Pressing TIMER increases time. Built-in timer activates pump daily at same time for set hours.
3. Lock keypad controls: With desired hour value showing, press LOCK/UNLOCK button until a "beep" is heard. This prevents unauthorized changes. System automatically locks after 10 seconds if forgotten.

Readjust operating time if necessary:

• Press LOCK/UNLOCK button until a "beep" is heard to unlock keypad. Current programmed time flashes. Repeat steps 2-3.

Stand-by/Power Saving Mode:

• When cycle ends, LED display shows “00”. System is in Stand-By mode. After 5 minutes, it enters Power Saving mode, LED shows ".". System automatically turns on in 24 hours.
• While in Power Saving mode, pressing any button briefly displays programmed time then "00".

2. To stop pump, press ON/OFF button again.

Operating Time Tables Summary

The manual includes detailed tables for recommended sand filter pump operating times for various Intex and non-Intex above-ground pool sizes. These tables specify the water capacity (in Gals and Liters) and the corresponding operating hours per cycle for models SF80220-2, SF70220-2, and SF60220-2.

For example, an Intex Easy Set® Pool (457cmx84cm / 15'x33") with a water capacity of 2587 Gals (9792 Liters) requires 2 hours of operating time for model SF80220-2. Larger pools, such as the Rectangular Ultra Frame Pool (488cmx975cmx132cm / 16'x32'x52") with 14364 Gals (54368 Liters), may require up to 9 hours for SF80220-2, 7 hours for SF70220-2, and 6 hours for SF60220-2.

The timer setting has an additional 10 minutes over the actual setting.

Motor Pre-Filter Cleaning and Maintenance

It is essential to change any damaged element or set of elements as soon as possible. Use only parts approved by the manufacturer.

1. Ensure filter pump is switched off and power cord is disconnected.
2. Turn both plunger valve handles fully clockwise to close valves and prevent water flow.
3. Release pressure by opening the sediment release valve (19) on the lower side of the pre-filter housing.
4. Unscrew the leaf trap cover (31) counter-clockwise, then remove the basket (16) and leaf trap o-ring (15) from the pre-filter housing.
5. Empty and flush the basket using a garden hose (a plastic brush may be used, but not metal).
6. Clean and rinse the inside of the pre-filter housing and the leaf trap O-ring with a garden hose.
7. Reinstall the leaf trap O-ring, basket, and leaf trap cover.
8. Close the sediment release valve (19).

All filter and filter media should be inspected regularly for debris build-up. Disposal of used filter media should comply with local regulations and legislation.

Pool Care & Chemicals

• All pools require care for clear and hygienically clean water. Consult your pool supply dealer for proper use of chlorine, algaecide, and other chemicals.
• Keep pool chemicals away from children.
• Do not replenish chemicals in pool while occupied to avoid skin or eye irritations.
• Daily pH checking and chemical treatment are very important. Consult local swimming pool supply store for instructions.
• First filling may require extra additives and filtering time. Do not swim until pH is balanced.
• Chlorinated water may damage lawns, gardens, or shrubbery. Note that some grass types may grow through the liner.
• Filter run time depends on pool size, weather, and usage level. Experiment for clean, clear water.
• European standard EN16713-3 lists additional pool water quality and treatment information at www.intexcorp.com/support.

Long Term Storage & Winterization

1. Before emptying pool for long term storage or relocation, direct water to an acceptable drain receptacle away from the house. Check local regulations for disposal.
2. Switch off unit and disconnect power cord.
3. When pool is empty, disconnect all hoses from pump and plunger valves and remove strainers/plunger valves from pool wall.
4. Unscrew drain valve cap (9) counter-clockwise from drain valve to thoroughly drain tank. Drain valve is at bottom of filter tank.
5. Disassemble pump motor from tank base.
6. Leave sand filter pump pieces and hoses outside to thoroughly air dry.
7. Coat the following o-rings and washers with petroleum jelly for long term storage: L-shape o-ring (11 & 18), Pump hose O-rings (22), Strainer valve assembly step washers (23), Flat strainer rubber washers (25).
8. Depress the 6-way valve handle and rotate to "N" position. This allows water to drain from valve. Leave 6-way valve in this inactive position.
9. Place all dry pieces and pump motor in original packaging for storage. To avoid condensation or corrosion, do not cover or wrap pump motor with plastic bags.
10. Store pump motor and accessories in a dry place (0°C/32°F to 40°C/104°F).
11. Cover tank with a tarpaulin or plastic sheet to protect it from weather.

Troubleshooting Guide Summary

The manual provides a comprehensive troubleshooting guide to address common issues with the sand filter pump. It lists various "Troubles" (e.g., Filter Motor Fails to Start, Filter Doesn't Clean Pool, Pump Doesn't Pump Water, Hose Leaking, Pressure Gauge Doesn't Work, Sand Flowing Back into Pool, Air Connector/Jet Valve Leaking) along with their potential "Causes" and corresponding "Solutions".

For instance, if the "Filter Motor Fails to Start", causes could be unplugged motor, tripped GFCI/RCD, or overheated motor. Solutions include plugging in, resetting breaker, or allowing motor to cool. If "Sand is Flowing Back into the Pool", causes are sand being too small or calcified, with solutions being to use specified No. 20 silica sand or glass sand (0.45 to 0.85 mm particle size, Uniformity Coefficient less than 1.75) or changing the sand.

Users are advised to consult this section for quick remedies to operational problems.
