During this operation, it is advisable to observe the pressure gauge from time to time as this indicates the degree of the
filter. When the pressure reaches 18.5 PSI a « BACKWASH » should be carried.
0,8kg/cm² - 11,4 PSI :
Normal pressure at the
beginning of a filtering cycle.
1,3kg/cm² - 18,5 PSI :
This pressure indicates that
it is necessary to backwash.

BACKWASH
Each load of sand forms thousands of channels which pick up all the material contained and
caught up in the filtering process, the number of free channels allowing the water to pass is
continually decreasing. This is why the pressure rises progressively until it reaches 1,3 Kgs/cm². At
this pressure the filtering sand is unable to collect any more impurities and must be cleaned as
follows: Turn the selector valve to the “BACKWASH” position and with the main drain and return
valves open, switch on the pump and run it for 2 minutes. When this operation is completed, the
dirt blocking the filter will have been removed
Attention
: Too much time in this operation could cause damage to the filter collector unit.

RECIRCULATE
In this position, the selector valve allows the water from the pump to go directly to the spa
without passing through the inside of filter.

WASTE
If the spa needs to be drained, this can be done using the filter pump. In order to do this, the
selector valve should be in the « WASTE » position. The motor is run with the main drain valve
fully open, for the pump to have sufficient suction. For the pump to suction, keep the préfiltre
and the main drain pipes full of water.
Before drainage, make sure that the valves and the bottom cleaner valves are closed.

RINSE
After the carrying out the « BACKWASH »operation on the filter and placing the installation in the
« FILTER » position, the water flowing into the spa will be cloudy for a few seconds, so to prevent
it from reaching the spa is a « RINSE » position for the selector valve which is operated as follows:
immediately after the “BACKWASH” put the valve in the “RINSE” position and switch on the pump
for 1 minute, after which the pump is switched off and the valve placed in the “FILTER” position.
This position ensures that the filtered water goes directly to the drain.
