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 long 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

tee 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.
