Страница: 4 / 8

Installation:
To install the flow switch correctly follow these instructions:
- When selecting the blade, identify the diameter of the
pipe to which the appliance will be fitted;
- The appliance comes pre-fitted with the 1” blade;
- For diameters of 1 1/4” (DN 32) and above, the pre-
fitted blade should be removed and the l ong blade
fitted, cutting it to the correct corresponding size for
the desired diameter;
- Fit the flow switch to the pipe, carefully observing
the direction of flow indicated by the arrows stamped
on the cover and on the switch mounting plate. When
fitted, the distance between the upper surface of the
pipe and upper surface of the switch mounting plate
should be 3 1/8” (80 mm);
- The tee connection in the pipe can be formed by
the direct welding of a threaded socket;
- This also applies to a 1” (DN 25) diameter pipe,
as the blades are designed to be contained in these
smaller dimensions.
- It is however advisable to check that the weld is
free from burrs on the inside so that the blade can
move freely in the the connection;
- Whenever possible the flow switch should be installed
with control stem in the vertical position to avoid deposits
of impurities which may cause it to function incorrectly.
