INSTALLATION INSTRUCTIONS FLOW RATE SENSOR SCREW-IN HEAT METER · CF-ULTRAMAXX
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
the unit. Remove the distance piece and the seals, and if necessary, clean the
sealing surfaces.
Replacement:
• Turn off the circulation pump
• Close the shut-off valves and release pressure in the pipe
• 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.
INSTALLATION OF A HEAT METER (FIG. 2)
Install the compact heat meter with new seals in the direction of the flow (follow
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.
