5. USER MANUAL
ATTENTION
ALWAYS STOP THE PUMP BEFORE CHANGING THE POSITION OF THE
SELECTOR VALVE.
5.1. FILTRATION
With the pump stopped, put the selector valve handle on FILTER. Start up the pump.
Periodically check the manometer during operation, which will indicate the degree of
saturation of the filter.
5.2. WASH
The solid particles in the pool that are collected by the sump and the skimmers
remain in the sand in the filter, which constantly decreases the water flow. Due to

this, the pressure increases progressively. When the pressure reaches 1.3 kg/cm , a
WASH will be done (this is an approximation; it depends on the distance between
the unit and the pool, its location, etc.).
Proceed as follows:
Put the selector valve in the WASH position and start the pump. Run this for 2
minutes. Always check the window of the selector valve to ensure that this is the
correct time, since it depends on the amount of dirt accumulated in the filter.
1.3 kg/cm2 - 18.5 PSI: This pressure indicates when it is necessary to proceed with a WASH
