INSTALLATION (FIG. 1)

Turn off the heating circulation pump and close the ball valves. Check the instal-

lation location (return / supply) to make sure this corresponds with the print on

• Break open the seals and unscrew the temperature sensor from the supply

T-piece or from the supply ball valve

• Remove the old heat meter and the seals, and if necessary, clean the sealing

surfaces.

the flow direction arrows on the casing).

Caution: the cable must not be cut, squashed or damaged when

removing the unit and during installation!

Caution: ensure tension-free installation - if necessary, ensure that

the pipes are sufficiently anchored in front of and behind the heat

meter.
