5. Assembly/installation
1. Screw out the blanking cap or fitted meter in an anti-clockwise direction (a small amount of water may escape).
2. Remove old seal and clean sealing faces in the coupling housing.
3. Thinly grease sealing faces and profiled gasket in the coupling housing (use acid-free grease).
4. Only fit the newly supplied seal and check for its correct seating (see page 3, Fig. 5 on the right side).
5. Screw the measuring capsule into the coupling housing using a hook spanner until hand-tight and then tighten up
to the metallic stop (approx. 1/8 to up to 1/4 turn).
6. Turn the calculator to an easy-to-read position..

5.3 Fitting location and calming section

• DN 15/20 and measuring capsule: The fitting location is optional (horizontal, vertical or overhead). No calming
section is necessary.
• DN 25-40: The fitting location can only be horizontal or riser or downpipe variants are available. With a straight
inlet path, a calming section of 3 x D is required, with a 90° elbow upstream of the inlet path, a calming
section of 10 x D is necessary.
• DN 50-100: Only a horizontal fitting location is possible. With a straight inlet path, a calming section of 3 x D is
required, with a 90° elbow or a T-piece upstream of the inlet, a calming section of 5 x D is necessary.
• With heating systems with no temperature mixing or temperature stratification, an inlet path of 10 x D is
necessary.

5.4 Fitting the temperature sensors

With meters with 2 free temperature sensors, the temperature sensors are identified with colour name plates.
RED - for installing in the high temperature pipe.
BLUE - for installing in the low temperature pipe.
For meters with only one free temperature sensor, the labels can also both be grey. The installation location of the meter
and the free temperature sensor result from the meter type and the assembly position specified on the name plate.
