Installation Instructions

Note: In the following text, the term meter refers to
both the heating meter, the cooling meter and the flow
meter, unless they are otherwise differentiated.
1. General
The meter left the factory in a faultless condition where safety
is concerned. Adjustments, maintenance work, replacement of
parts or repairs may only be carried out by specialist staff who
are aware of the associated hazards. The manufacturer will
provide additional technical support on request. Calibration
relevant security seals on the meter must not be damaged or
removed. Otherwise the guarantee and calibration validity of
the meter will lapse.

Keep the packaging so that you can transport the meter in
its original packaging following expiry of the calibration va-
lidity.

Lay all cables at a minimum distance of 500 mm to high
voltage and high frequency cables.

A relative humidity of <93 % at 25 °C is permissible (with-
out condensation).

Avoid cavitation in the whole system due to overpressure
i.e. at least 1 bar at qp and approx. 3 bar at qs (applies for
approx. 80 °C).

The 110 V / 230 V network parts correspond to protection
rating II so that the line voltage does not need to be dis-
connected when changing the meter.

Safety Information

The meter may only be used in building service engi-
neering systems and only for the applications de-
scribed.
The meter is designed in accordance with the guide-
lines of the environment categories M1+E1 and must
be fitted in line with these regulations.
The local regulations (installation etc.) must be ad-
hered to.
Adhere to the operating conditions according to the
dial plate during use. Non-adherence can cause haz-
ards and the guarantee will lapse.
Adhere to the AGFW requirements regarding circulat-
ing water (FW510).
The meter is only suitable for circulating water in
heating systems.
The meter is not suitable for drinking water.
Do not lift the meter by the electronic unit.
Be aware of sharp edges on the thread, flange and
measuring tube.
Only personnel, trained in the installation and opera-
tion of meters in heating and cooling systems, may
install and remove the meter.
Only install or remove the meter when the pipes are
pressure-less.
After installing the meter, check the leak-tightness of
the system.

To install the meter proceed as follows:


Guarantee and calibration validity will lapse if the
calibration relevant security seals are broken.
Only clean the meter from outside with a soft, lightly
wetted cloth. Do not use any spirit or cleaning solvent.
The 110 V / 230 V connections may only be made by
an electrician.
The meter may only be powered up once the installa-
tion has been completed. There is otherwise a danger
of electronic shock on the terminals.
A defective or obviously damaged appliance must be
disconnected from the power supply immediately and
replaced.
As far as disposal is concerned, the meter is a waste
electronic appliance in the sense of European Di-
rective 2012/19/EU (WEEE) and it must not be dis-
posed of as domestic waste.
- Dispose of the meter through the channels pro-
vided for this purpose.
- Respect the local and currently valid legislation.
- Dispose of used batteries at the collection points
provided for them.
The meter contains lithium batteries. Do not dispose
of the meter and the batteries with domestic waste.
Observe the local stipulations and laws on disposal.
You can return the lithium batteries to the manufac-
turer for appropriate disposal following use. When
shipping please observe legal regulations, in particu-
lar, those governing the labelling and packaging of
hazardous goods.
Do not open the batteries. Do not bring batteries into
contact with water or expose to temperatures above
80 °C.
The meter does not have any lightning protection.
Ensure lightning protection via the in-house installa-
tion.
Only fit one compartment for the power supply. Do not
remove the red locking hatch.
Installation
Determine the place of installation in line with the inscrip-
tion on the meter.
Note: At a heating meter
ing/cooling meter the mounting place of the flow
sensor cold side is equivalent to return
mounting place of the flow sensor hot side is equiva-
lent to flow .
Note: At a cooling meter
the flow sensor hot side is equivalent to the return
. The mounting place of the flow sensor cold
side is equivalent to flow
Observe the dimensions of the meter and check whether
there is sufficient space available.
