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).

OPERATING INSTRUCTIONS (continued)

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.

2. 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”
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.

3. BACKWASH

 - Ensure the pump is off, depress the 6-way valve

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.

4.

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/drai

n 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.

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. 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.

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.

10.

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.
