Installation guide Thermal Energy Meter Supercal 739
Installation
The prescriptions related in the standard EN1434-6 must be respected when the Supercal 739 is installed.
Depending on its particular version and use (heat and/or cooling meter), the energy meter must be fitted on the “cold” or “hot” pipe side of the
installation in compliance with the indications showed on the LCD display, 1
st
position of the service menu “hot pipe” / “cold pipe”.
In the standard version, the integrator is parameterised by default for installation on the “cold” pipe side. Installation on the “hot” pipe side must be specified
with the order.
In any particular installation, mixed mounting positions (horizontal and vertical) must be avoided because the measuring ranges are different.
Place the flow meter correctly according to the direction of the fluid (an arrow can be seen on the flow meter).
Horizontal mounting with the integrator facing downwards is not permitted. Also avoid fitting in a position which may cause an air bubble to build up inside
the mechanical meter.
The energy meter must be fitted between two shutoff valves. The flow meter must be installed ahead of any monitoring valves so as to avoid any potentially
interfering influence. Waterproof will be checked at the various mounting points.
The heat conveying liquid must be equivalent to water without any additives according to standard FW510 of the AGFW (German District Heat-
ing Association). If additives are added to the water, the user must ensure the compatibility of the materials used in the thermal energy meter which are in
contact with these additives.
The integrator can be separated from the flow meter and installed at a sufficient distance from the flow meter if:
- The meter has to be installed in a confined space.
- In a cooling installation, possibility to isolate the flow meter.
The pipes are generally free from air before the installation is brought into service. Follow the insulation instructions for cooling installations. Final commis-
sioning must be performed and documented.
Wall-mounting of the integrator
The integrator can be separated from the flow meter and fixed against a wall using the wall fixture supplied with the energy meter. If possible, install the
wall fixing component above the flow meter.
The wall fixing component, together with a double-sided adhesive tab, is delivered with the Supercal 739 (Figure 1).
The wall fixing component can also be screwed on to the wall (screws are not supplied).
To separate the integrator from the flow meter press laterally with one hand on the two locking buttons, while pulling the integrator upwards (Figure 2).
Fix the integrator onto the wall fixing component taking care not to jam the cable which connects the integrator to the flow meter and stick the adhesive tab
behind the wall component. Secure the assembly to the wall (Figure 3).
To remove the integrator from the wall support, it will be sufficient to press laterally on the two locking buttons while pulling the assembly towards you.
Rewind the connection cable at the position provided for this purpose on the flow meter (1) and re-insert the integrator (2).
