6. Installation of the thermal energy meter
6.1 Superstatic 749
To install the Superstatic 749, the following steps must be respected:
Flush out the installation pipes carefully in compliance with the
DIN/EN standard specification.
Close the shutoff valves before and behind the meter.
Open the drainage valve to reduce the pressure and discharge the
water contained in the pipe between the two shutoff valves.
Consider the direction of flow circulation. Check the flow direction
with the arrow figuring on the flow meter.
Place a gasket on each side of the flow meter. Only use appropriate
new gaskets.
Make sure that the gaskets are carefully positioned in relation to the
water pipe and flow meter unions.
Tighten the fixing nuts firmly by hand. Then tighten up to the
mechanical end stop using a mounting tool.
Install the temperature sensor.
Turn the display into the desired position for reading.
Check the waterproof of the meter placed under pressure.
Seal the flow meter and the temperature sensors.
6.2 Mounting cable for the pulse input function
The pulse inputs are built with SELV circuits (Safety Extra Low Voltage) and must be only
connected with SELV circuits. The electrical characteristics are displayed on page 22.
6.3 Mounting cable for the pulse output function
The pulse outputs are built with SELV circuits (Safety Extra Low Voltage) and must be only
connected with SELV circuits. The electrical characteristics are displayed on page 22.
