The importance of backwashing cannot be overstated. Dense filter media can become "packed" without proper
and frequent enough backwashing. Debris will remain trapped and create channeling within the filter bed.
This will result in the filter bed exhausting early. Moreover, if debris is not flushed from the media grains.the filter
bed will become dirtier and dirtier as time goes on until the filter operation fails.
3. BACKWMHING INSTRUCTIONS
a. Switch off the Pump I Close the Inlet Valve.
If a pump is installed, switch the pump on and off, instead of closing and opening the Inlet
Valve.
b. Release the filter's pressure by loosening Pressure Release Valve until the Pressure Gauge needle drops to
zero <O>.
c. Retighten Pressure Release Valve.
d. Depress and turn Handle 180"C to the BACKWASH position.
In the BACKWASH position.the water flow is automatically reversed through the filter so that it is directed to the
bottom of the filter vessel, up though the sand, flushing the previously trapped dirt and debris out the waste line.
e. Switch on the Pump I Open the Inlet Valve. Backwash water will flow out through drain pipe.
f. When the backwash water in the sight glass appears clear, Switch off the Pump I Close the Inlet Valve.
g. Depress and tum 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.
h. Switch on the Pump I Open the Inlet Valve. Rinse water will flow out through the drain pipe.
i. When the rinse water in the sight glass appears clear. Switch off the Pump I Close the Inlet Valve.
j. Depress and tum the handle to the Filter position and Switch on the Pump I Open the Inlet Valve for normal
operation.
6. 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 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.
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.
