COMMISSIONING AND OPERATING RECOMMENDATIONS
WARNING: Carry out a back wash and rinse before using the filter for the first time to clean the filter and remove any
excess sand and impurities (see the paragraph Filter and Valve operation). After the backwash, rinse before turning the
valve to the Filtration position. After the backwash, with the multi-port valve set to Filtration, the black needle on the
pressure gauge indicates the nominal pressure experienced by the filter. This pressure will vary as a function of the pump
flow rate, the static pressure and load losses across the pipes. To keep a record of this nominal pressure (calibration),
adjust the dial of the pressure gauge so that the blue needle aligns with the black needle.
NB: Stop the pump before each manipulation of the 6-way valve. Failure to respect this instruction will result in damage
to the filter, the valve and pump and cancellation of the guarantee.
-FILTER AND VALVE OPERATION:
- FILTRATION: Water arrives from the pump, passes from the top to the bottom of the filter and is returned to the pool.
- BACKWASH: Water passes through the filter from the bottom to the top gathering trapped impurities and carrying
them directly to waste. Backwash should be carried out as soon as the needle in the pressure gauge enters the red.
- RINSE: Water passes through the filter from top to bottom before being directed to waste (allow approx 30 sec for this
process.).
- CIRCULATION : Water circulates without passing through the filter.
- DRAIN: Water passes from the pool to waste (flocculation, etc.).
- CLOSED: No water circulation. Never allow the pump to run while the valve is in this position. Similarly, make sure that
the position of the various valves will allow circulation of water before turning the pump on.
LENGTH OF THE FILTRATION CYCLE:
The length of the filtration cycle depends on the theoretical time taken for all the water in the pool to pass through the
filter. For private pools, the max time allowed for all the water to be recycled is 8 hours.
We recommend the following as a function of water temperature:
- Below 14°C : 5 to 6 hours per day.
- From 15° to 23 °C : 6 to 8 hours per day.
- Above 23 °C : 10 to 12 hours per day.
The higher the bather load and the pool water temperature, the longer the filtration cycle should be. To optimise
filtration efficiency, run the filter during the day (between 8:00 am and 9:00 pm) and, more generally, while the pool is in
use (one bather pollutes 3 m³ of water ).
CLEANING THE PREFILTER AND FILTER BACKWASH:
After a certain time, a drop in the flow rate at the return fittings will be noted. This is due to progressive clogging of the
filter or pump prefilter.
PRE-FILTER
1 - If the pressure indicated on the pressure gauge falls below the nominal pressure indicated by the blue needle, clean
the pump pre-filter.
- Stop the pump.
- Turn the 6-way valve to CLOSED.
- Close the suction and return valves.
- Open the pump pre-filter.
- Remove the basket.
- Use a water jet to remove any impurities.
- Put the pre-filter basket back.
- Put the pre-filter lid back on making sure that the seal is correctly positioned and that there is enough water to prime
the pump.
- Put the 6-way valve to FILTRATION.
- Open the suction and return valves.
- Switch the pump on.
- Vent the filter (this should be done each time the pre-filter is cleaned and at least once a week).
FILTER
2 - If the pressure indicated by the pressure gauge rise above the nominal pressure, carry out a filter back wash.
- Stop the pump.
- Check the pre-filter and clean it out if necessary (as indicated above).
- Before proceeding with a filter back wash or draining the pool, make sure that the waste pipe (not provided) has been
attached to the waste outlet.
