7. Depress and turn the handle to the RINSE position.
In the RINSE water flow is directed through the
filter bed and out of the filter through the backwash
outlet. This process settles the filter media bed into
place and ensures any dirt or debris is rinsed out of
the filter, preventing possible return to the pool.
8. Switch on the Pump. Open the Inlet Valve. Rinse
water will flow out through the drain pipe.
9. When the rinse water in the sight glass appears
clear. Switch off the Pump. Close the Inlet Valve.
10. Depress and turn the handle to the Filter position
and Switch on the Pump. Open the Inlet Valve for
normal operation.
CHAPTER 7
: MAINTENANCE
The filter media will only require replacement once it
has reached the limits of its designated life. Refer to
the product information of the particular filter media
used. To ensure the maximum life of the selected filter
media, please follow the procedures below.
1. Backwash the filter regularly according to the
instructions set under BACKWASHING.
2. Maintain a correct chemical balance for your pool
or spa’s water. The chemical balance of the water
is a relationship between its pH, Total Alkalinity,
Calcium Hardness and water temperature. The
water must be maintained to the following:
- pH Level: 7.2-7.8.
- Total Alkalinity: 80-175ppm
- Calcium Hardness: 175-300ppm
CHAPTER 8
: TROUBLESHOOTING
Above normal or excessive force to operate the
Multiport Valve
: Scoring or jamming with foreign
matter or debris. If this condition persists after rinsing,
disassemble the valve to clear. Continued operation
of the valve may result in a non-sealing condition
(damage to spider gasket). This will lead to water loss
to the backwash line or to inefficient filtration.
Dirty Water
:
1. Insufficient filtration time.
2. Heavy contaminants or dirt load.
3. Dirty filter, requires backwashing.
4. Air leaking on suction (influent line).
5. Pump impeller vanes blocked.
6. Insufficient water supply (water level low, blockage).
7. Pump not primed.
8. Incorrect water chemistry.
9. Excessive flow of water for filter size. Foreign
matter or debris forced through filter bed and
through the underdrain.
Filter Media in the backwash
:
1. Excessive quantity of media in the filter.
2. Excessive water flow.
3. Incorrect size or grade of filter media.
Filter Media returning to Swimming Pool or Spa
:
1. Filter is on recirculate.
2. Verify it is the filter media and not from another
source.
3. Damage to the underdrain laterals.
4. Damage or incorrect fit of Multiport Valve are
correct.
5. Incorrect or mixed grades of media in the filter.
Short filtration cycles
:
1. Presence of algae or scale builds up.
2. Check water chemistry.
3. Excessive water flow, check pump size, mains
water flow.
4. Filter blockage. Clean filter media.
