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.

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 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.

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.

A. Set the timer dial to the desired operating hours. See operation time table (see drawing 31).

B. 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.

C. Operating hours can be re-adjusted if necessary. Follow step A – B.

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

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

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

IMPORTANT: If you continue to experience difficulty, please contact our Consumer Service Department for assistance. See separate “Authorized Service Centers” sheet.

MOTOR PRE-FILTER CLEANING AND MAINTENANCE

1. Make sure the filter pump is switched off, then disconnect the power cord from the electrical outlet.

3. Release the pressure first by opening the sediment release valve (19) located on the lower side of the pre-filter housing (see drawing 32).

4. In a counter-clockwise motion unscrew the leaf trap cover (14), then remove the basket (16) and leaf trap o-ring (15) from the pre-filter housing (see drawing 33).

5. Empty and flush the basket using a garden hose, may use a plastic brush to remove deposits from the basket. Do not use metal brush.

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 to the pre-filter housing.

8. Close the sediment release valve (19) back.

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.

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. If anti-freeze solution is needed, use only propylene glycol. Propylene glycol is non-toxic and will not damage plastic system components; other anti-freezes are highly toxic and may damage plastic components in the system.

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 plunger valves and remove the strainers/plunger valves 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 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).

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 0 degrees Celsius (32 degrees Fahrenheit) and 40 degrees Celsius (104 degrees Fahrenheit).
