Preparatory Work; Installing The Meter - meibes Rossweiner logoplus Guia De Instalacion

5. Assembly/installation
Preconditions
• The meter must be protected using suitable means against magnetite and dirt (e.g. strainer, water treatment, filter).
• Shut-off valves must be fitted upstream of the strainer and downstream of the meter.

5.1 Preparatory work

1. Thoroughly clean the pipeline.
2. Close the shut-off valves upstream and downstream of the meter and depressurise the pipeline.

5.2 Installing the meter

Dependent on the information on the name plate install the meter in the pipeline with lower or higher tem-
perature. When doing so install the meter so that the flow direction matches the arrow direction on the
housing (see Fig. 1, page 6).
Meter assembly
1. Remove the spacer or fitted meter (a small amount of water may escape).
2. Remove old seals and clean sealing faces.
3. Thinly grease sealing faces (use acid-free grease).
4. Only fit the newly supplied seals.
5. Fit the meter so it is free from mechanical stresses (observe the meter flow direction).
Tighten bolts or flange screws to a torque of approx. 50 Nm.
6. Turn the calculator to an easy-to-read position.
Measuring capsule
Only fit measuring capsules in coupling pieces designed to EN 14154 (IST).
