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. 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.
IMPORTANT: To prevent air lock, open the lower plunger valve (connected inlet hose) first
and then the upper plunger valve (connected outlet hose). Open the air release valves, wait
until water starts to flow out of the air release valves, close air release valves.
2.
Ensure the drain/waste outlet on the 6-way valve is not covered and directed to a proper draining
receptacle.
3.
BACKWASH
- Ensure the pump is off, depress the 6-way valve
and turn it to the “
BACKWASH
” position
(
see drawings 29 & 34
)
.
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/drain outlet or through the drain
sediment window.
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 30
)
.
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 28
)
.
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.
