OPERATING INSTRUCTIONS

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 30 mA. 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 6-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).

6-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).

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.  

1. 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. With water flowing into sand filter pump, the water pressure will allow the air trapped inside to escape from the air release valves (19). When all the air has escaped water will flow out of the valves (19). When this occurs gently finger tighten the valves (19) in a clockwise direction. 
2. Ensure the drain/waste outlet on the 6-way valve is not covered and directed to a proper draining receptacle. 
3. Ensure the pump is off, depress the 6-way valve and turn 2 it to the “BACKWASH” position (see drawings 24 & 29).
   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.
4. Switch on the pump (see drawing 30). 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 or through the drain sediment window. 
   NOTE: The initial backwash of the filter is recommended to remove any impurities or fine sand particles in the sand media.
5. Switch off the pump, change the 6-way valve to “RINSE” position (see drawing 25).
6. Switch on the pump and run the pump for about one minute to level out the sand bed after backwashing the sand media.
7. Switch off the pump, change the 6-way valve to “FILTER” position (see drawing 23).
8. 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.
9. 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.

Operating the system under “TIMER” mode or manually:

To operate the sand filter pump in “FILTER” mode under “TIMER” control:

1. Set the timer dial to the desired operating hours. See operation time table (see drawing 31).
2. Turn on the pump by pressing the switch to “    ” position, the sand filter pump is now filtering the water and will stop after the operating hours are completed. The built-in timer will now operate for the number of hours selected at the same time each day.
3. Operating hours can be re-adjusted if necessary. Follow step A – B.

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

1. Turn on the pump by pressing the switch to “-” position, the sand filter pump is now filtering the water.

2. To turn off the pump, press the switch to “O” position.

7. Reinstall the leaf trap O-ring, basket and leaf trap cover into the pre-filter housing.
8. Close the sediment release valve (19) again.

POOL CARE & CHEMICALS

• All pools require maintenance to keep their water clear and hygienic. With proper chemical control, your filter will help achieve this goal. Consult your pool supply dealer for instructions on the proper use of chlorine, algaecide, and other chemicals necessary for sparkling clear water.
• Keep pool chemicals away from children.
• Do not add chemicals to the pool while it is filling. Skin or eye irritation may occur.
• Daily pH checking and chemical maintenance of the water are essential and cannot be overemphasized. Chlorine, algaecide, and maintenance of proper pH levels are necessary when filling the pool as well as throughout the season. Consult your local pool supply store for instructions.
• The first filling of the pool season may have brackish water that requires additional water additions and additional filtration time. Do not allow swimming in the pool until the pH level is balanced. Consult your local pool supply store for instructions.
• Chlorinated water can damage grass, gardens, or shrubs when children play in the pool and splash water out of the pool. The grass area under the pond liner will be destroyed. Note that some types of grass can grow through the liner.
• Filter run times vary depending on pool size, weather, and usage levels. Experiment with different run times to produce clear, clean water.

CAUTION
Concentrated chlorine solutions can damage pool liners. Always follow chemical manufacturer's instructions, as well as health and hazard warnings.

LONG TERM STORAGE & WINTERIZATION

CAUTION
Allowing water to freeze will damage the sand filter and void the warranty. If an antifreeze solution is necessary, use only propylene glycol. Propylene glycol is non-toxic and will not damage plastic system components; other antifreezes are very toxic and can damage plastic components in the system.

1. Before emptying your pool for long-term storage, or relocation, make sure the water is directed to an acceptable drain away from the house. Check local regulations for specific instructions regarding pool water disposal.
2. Turn off the unit, and unplug the power cord from the wall outlet.
3. When the pool is empty, disconnect all hoses from the pump and plunger valve and remove the strainer/plunger valve from the pool wall.
4. In a counterclockwise motion, unscrew the drain valve (9) from the drain valve to drain the tank completely. The drain valve is located at the bottom of the filter tank.
5. Remove the pump motor from the bottom of the tank.
