When starting up for the first time, read the pressure of the pressure gauge. It
is recommended to take note of this pressure, as later it will be used to know
whether the filter is dirty and if "WASHING" is required. "WASHING" should
be done when the pressure gauge indicates an increase of 0.5 kg/cm
pect to the initial pressure of the filter. it is advisable to observe the pressure
gauge from time to time as this indicates the degree of saturation of the filter
Bear in mind that the valves at the bottom of the pool and the skimmers will
be adjusted according to the amount of floating particles on the surface of the
water. The main drain and skimmer valves will be regulated according to the
quantity of floating material found on the surface of the water. Bear in mind
that with the main drain valve fully open there will be little suction from the
skimmers. If the surface sweep of the skimmers is to be stronger, reduce the
flow from the main drain.

Note: the initial operating point will depend on the design of the installation and the flow rate used.
BACKWASH:
When the pressure has reached 0.5 kg/cm
