Instruction for use | Supercal 739
6. Installation
The prescriptions related in the standard EN1434-6 must be respected when the
Supercal 739 is installed.
In the standard version, the calculator is parameterised by default for installation on the “cold”
pipe side. Installation on the “hot” pipe side must be specied with the order.
Depending on version and use (heat and/or cooling meter), the energy meter must be tted on
the “cold” or “hot” pipe side of the installa-tion in compliance with the chosen conguration. If
the device was ordered with the conguration option, some parameters can be changed using
the “Cong” menu during commissioning.
Within the same installation, mixed mounting positions (horizontal and vertical) should be
avoided. Place the ow meter correctly according to the direction of the uid (an arrow  can
be seen on the ow meter).
Horizontal mounting with the calculator facing downwards is not permitted. Also avoid tting in
a position which may cause an air bubble to build up inside the mechanical meter.
The energy meter must be tted between two shutoff valves. The ow meter must be installed
ahead of any monitoring valves so as to avoid any potentially interfering inuence. 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 Heating 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.
6.1 Mounting of the calculator for a cooling application
Only the ow meter can be fully isolated. Separate the calculator from the ow meter and x
using the wall support aid.
It is recommended to separate the calculator from the ow meter and installed at a sufcient
distance from the ow meter if:
- The meter has to be installed in a conned space
- The meter is in connection with mounting in condensing environments
- To prolong the battery life time
The pipes are generally free from air before the installation is brought into service. Follow the
insulation instructions for cooling installations. Final commissioning must be performed and
documented.
6.2 Wall mounting of the calculator
The calculator can be separated from the ow meter and xed against a wall using the wall
xing component, together with a double-sided adhesive tab delivered with the Supercal 739
(Figure 1). If possible, install the wall xing component above the ow meter.
The wall xing component can also be screwed on to the wall (screws are not supplied).
To separate the calculator from the ow meter press laterally with one hand on the two locking
buttons, while pulling the calculator upwards (Figure 2).
Fix the calculator onto the wall xing component taking care not to jam the cable which
connects the calculator to the ow meter and stick the adhesive tab behind the wall component.
Secure the assembly to the wall (Figure 3).
