Installation Instructions

Note: In the following text, the term meter refers to both
the heating meter and the cooling 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 staffs 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 (without
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).

Safety Information

The meters may only be used in building service
engineering plants 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
hazards and the guarantee will lapse.
The meter is only suitable for circulating water in
heating plants.
Adhere to the AGFW requirements regarding circulat-
ing water (FW510).
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 flow meter, check the leak-
tightness of the system.

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.
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.
Installation
Determine the place of installation in line with the inscrip-
tion on the meter.
Note: At a heating meter
the flow sensor cold side is equivalent to return
. The mounting place of the flow sensor hot
side is equivalent to flow
Note: At a cooling meter
of 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.
Clean the appliance thoroughly before installing the meter.
Fit the meter vertically or horizontally between two slide
valves so that the arrow on the housing and the flow direc-
tion match. Also observe the installation situations and the
following examples of installation.
Fit the temperature sensors in the same circuit as the me-
ter. Observe the admixtures.
Seal the temperature sensor and the fittings to protect
against manipulation.
