INTRODUCTION: -
The SANDPIPER High Rate Sand/Zelbrite Filter incorporates
the latest technology together with components proven
in the swimming pool industry. It has been designed for
use with either fresh or salt water and for best performance
it should be installed with the recommended Poolstore
Pump and Motor.
Its' installation should be undertaken by a person who
is knowledgeable of swimming pool filtration requirements.
In the event of advice on installation being required,
then please contact the source from which the unit was
purchased or the manufacturer.
LOCATION: -
The filtration unit should be placed in its permanent
location, preferably as close to the pool as practicable.
It should be located on a level concrete base or concrete
slab having minimum dimensions of 1 metre x 750mm.
The minimum clear vertical height above the concrete
slab should be 1.2 metres and 105mm is required behind
the slab to allow easy removal of the pump and motor and
to provide cooling ventilation for the electric motor.
WEATHER PROTECTION: -
The SANDPIPER filtration unit including the pump
and motor are made of weather resistant and UV Stabilised
materials and as such no further weatherproofing is necessary,
although they may be covered if desired. Please allow
adequate ventilation if covering the installation.
GETTING READY: -
1. Remove filtration tank and all components inside
tank from filter carton.
2. Remove valve from separate carton.
3. Remove pump and motor from other carton if purchased
as a complete system.
4. Check quantity and grade of sand or quantity
of "Zelbrite" media (if this is the type of
media being used).
ASSEMBLY: -
1a Normal Assembly: -
Place filtration tank on a concrete slab, with the label
facing you. It should be positioned so that the pump and
motor are on the left hand side when you face the unit.
1b Alternative Assembly: -
Position tank with the label facing away from you and
the pump and motor will then be on the right hand side
when you face the unit. If unit is palced in this position
then the pressure gauge will be difficult to read and
the 6 way valve handle more difficult to operate.
2. Check that the riser pipe assembly is firmly
located in the tank base and that the
laterals are in position and in the tank leg cavities.
3. Place the plastic media chute over the top of
the standpipe to stop media entering this
pipe when filling the tank and to stop media from entering
tanks valve bolt holes.
4. Fill the tank to approximately 40mm above the
laterals with water.
5. Pour the specified quantity
of fine sand or Zelbrite into the tank,
distributing it evenly. Media level should be approximately
300mm from the
very top of the tank when full.
6. Remove the plastic media chute and clean the
tank top of any media particles.
7. Fill the filter tank with water.
8. Check that the small 'O' Ring is in the groove
inside bottom of the valve, and
lubricate with silicone grease or rubber grease.
9. Lubricate the large 'O' Ring and place it in
the groove in the underside of valve.
10. Take the valve and position handle so that
the pointer is located in the "Filter" slot.
11. Fit the valve onto the tank with the bolts
provided and tighten after all the
bolts have been placed in position.
There should be very little clearance between the underside
of the valve and the top of
the tank.
12. Place the pump and motor in position approx.
200mm away from the filter tank with
pump inlet facing you for normal assembly.
13. Screw union into top of pump and plumb between
this point and the union marked
"Pump" on the valve.
14. Screw union into front of pump and plumb to
suction line of pool.
15. Connect return pipe work to union on valve
marked "Return".
16. Connect backwash line to union on valve marked
"Waste".
17. Remove clear Hair and Lint Pot lid off the
pump and fill bowl with water. Reseal lid
after lubrication of 'O' Ring.
18. Place valve handle on "Waste" position.
19. Remove plastic plug from valve body and screw
in pressure gauge.
Do not overtighten.
FILTER START-UP: -
Prior to the initial start-up, the pool should be over
filled to compensate for the initial loss of water:
1. With the valve in the "Waste" position,
turn on pump. Water will be drawn from the pool and discharged
with some air via the backwash line. This will assist
in the initial priming of the pump.
2. Turn off the pump and rotate valve to "Backwash"
position.
3. Turn on pump and run until the discharge water
becomes clear (as seen in the sight glass on the valve).
NOTE: During this initial cycle some excess media may
be discharged by the filter.
DO NOT BE ALARMED as the media bed in the filtration
tank will adopt its maximum volume for the particular
installation.
4. When the sight glass becomes clear, turn off
the pump and wait for at least 30 seconds before you then
…….
5. Turn valve to "Rinse" position and
then turn on pump. Water should become clear in sight
glass in a short period of time when you turn off pump,
and then …….
6. Turn valve to "Filter" position and
note pressure as shown on the pressure gauge.
NOTE: some air may still be discharged into the pool for
a short time.
7. Your SANDPIPER filtration system is now
providing you with clean filtered water ready
for swimming
8. Having noted the start up pressure (usually
about 70kPa) then it should be remembered
that the unit will require backwashing when the pressure
rises by an additional 40-50kPa.
BACKWASHING FILTER: -
Backwash when the pressure gauge reading reaches 120kPa
or as indicated in 8 above.
To Backwash: -
1. Turn off the pump.
2. Turn the handle to the "Backwash"
position.
3. Turn on pump and run until water viewed in the
sight glass becomes clear, usually 2 or 3 minutes.
4. Turn off the pump and wait a minimum of 30 seconds,
then …..
5. Turn the handle to "Rinse".
6. Turn on the pump and run for approximately one
minute.
7. Turn off the pump.
8. Turn the handle to "Filter" position.
9. Turn on the pump and a new filter cycle has
begun.
NB (a) Never vacuum while backwashing
(b) Never shift the valve handle while the pump
is running.
