17. FILLING AND CHARGING THE CIRCUIT WITH WATER
17.1 Filling the pool
Check that all the valves are closed and continue to fill the pool until the water level is 2/3 of the way up
the mouth of the skimmer. This is the optimum level for correct filter operation.
While filling, check the various fittings for leaks. Make sure that the liner is properly engaged in the liner
locking track around the entire periphery of the pool, particularly in the corners. If the liner has come away
it will usually be necessary to empty the pool in order to reattach it.
17.2 Filling the circuit with water
Check the various connection points for leaks.
Make sure that the pump is filled with water before starting it up. The pump should under no circumstances
be allowed to run dry. Make sure that the pre-filter is filled with water. If necessary, open the pump and fill
it and the skimmer line with water to facilitate priming.
Turn the 6-way valve to Backwash (to carry out a filter backwash before putting the filter into service).
Start the pump and check again for leaks.
17.3 Commissioning & operating the filtration system
17.3.1 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 debris (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.
17.3.2 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 to evacuate dirty water in the pipes).
• 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 he position of the various valves will allow circulation of water before turning
the pump on.
