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. Refer to the specifications of the filter media used and implement regeneration procedures
accordingly.
3. Maintain a correct chemical balance of your pool / spa water. The chemical balance of water is a
relationship between its pH, total alkalinity, calcium hardness and water temperature. The water must
be maintained at all times to the following:
PH LEVEL : BETWEEN 7.2 & 7.8.
TOTAL ALKALINITY
: BETWEEN 80 & 150ppm.
CALCIUM HARDNESS : BETWEEN 150 & 300ppm.
And within these tolerances be balanced to the Langelier Saturation Index within a range of -0.2 to
+0.2.
NOTE: Testing kits are available to test the water yourself or alternately bring a sample of the water
to a professional pool and spa shop.
4. Mains water and rural water supplies need to be monitored. Saturation (life) in mains water or bore
(rural) will vary depending on water quality.
5. To prevent damage to the pump and filter and for proper operation of the system, clean pump
strainer and skimmer baskets regularly.
6. Replace the pressure gauge if faulty readings are observed.

WINTERISING

Proper winterising procedures should always be taken in order to protect your filter in cold climates
[temperatures below freezing point]
1. Switch off the Pump / Close the Inlet Valve,
2. Open the air release valve and move the MPV handle to the winterise position [between Filter and
Waste] This will allow air to through to all ports.
3. Remove any drain plugs from the filter.
4. Drain water from the pipework.
TROUBLESHOOTING GUIDE
Above normal or Scoring or jamming with foreign matter or debris. If this condition persists after
excessive force rinsing, disassemble the valve to clear dirt and debris. Continued operation of the
to operate the valve may result in a non-sealing condition (damage to spider gasket). This will lead
Multiport Valve to water loss to the backwash line or to inefficient filtration.
Note: A filter sock is recommended during pool vacuuming, to prevent dirt and
debris lodging between the spider gasket and MPV body.
Water is not clear 1. Insufficient filtration time.
2. Heavy bathing or dirt load. Pool must be floculated and vacuumed
directly to waste.
3. Filter is dirty, requiring a thorough backwash.
4. Air leaking on suction (influent line).
5. Pump impeller vanes blocked.
6. In sufficient water supply (water level low, blockage).
7. Pump not primed.
8. In correct water chemistry.
9. Excessive flow of water for filter size. Foreign matter or debris forced
through filter bed and through the under drain.
10. Other restrictions including (pool suction cleaners) resistance from other
inline equipment such as strainers. Operating the filter on recirculate will
determine if the restriction is in the filter.
11. Clogged or channeled filter media. Perform thorough backwash or
regeneration.
