Installation

Normally the MICRO.2 pumps are installed between the skimmer and the swimming pool fil-
ter.
The pumps should be placed on a solid foundation, with the shaft in horizontal position and
the pre-filter cover on the top. It must be possible to remove the transparent cover to take
out the pre-filter basket for cleaning. The suction pipe must have at least the same diameter
as the pump suction inlet diameter. If the suction line is over 10 meters long, the pressure
losses must be taken into consideration. Install the pipes to avoid any air pockets
in its interior, especially in the intake pipe.
The following drawing shows a correctly fitted pipe.
Fig. 1
The pipes should be fitted in such a way that any pressure variation caused by temperature
changes do not to affect the pump.
If the piping is very long, it must be suitably supported in front of and behind the pump and
it is best to place a retention or anti-hydraulic ram valve in the drive.
