Installation and operating instructions
Mounting and lead-sealing material
1. Important directions
This instrument has been delivered by the
producers in consistency with sound safety
engineering. In order to ensure a safe installation
and operation job read the complete instructions.
It is only allowed to open covers and remove
parts, where this can be done by hand. Otherwise
life parts might be exposed. And connectors can
be alive, too. All repair and maintenance jobs
have to be done by specially trained and
authorized experts. If body and/or connection
cables show any damages put the instrument out
of operation and ensure that nobody can restart
its operation by mistake.
In order to protect PolluFlow against damage and
dirt leave it in its packing until you want to install it.
Do not clean it with anything else but a cloth
moistened with water.
Battery-operated meters:
The battery must not be opened by force, be
short-circuited or exposed
temperatures exceeding 80°C. Empty batteries
are special refuse and have to be disposed of at
suitable collection centres.
Mains-operated meters:
Protect the power pack by using a 6 A-fuse in the
installation site. Only specially trained and
authorized experts are allowed to do the
connecting job. Furthermore pay attention to the
standard technical rules - VDE 0100 in particular.
2. Installation
2.1 Installation of the flow meter
Applicable standard: EN 1434-6
Secure that installed flow meters are always
completely filled with heat resp. refrigeration
liquid. Air bubbles will interrupt the ultrasonic
signal and, therefore, cause measuring errors.
An arrow on the flow meter shows the flow
direction. The admissible operating pressure and
the admissible operating temperature must not be
exceeded.
Install shut-off valves before and after the flow
meter, so that there is no need to empty the pipe
system when the meter will be exchanged on
expiry of the verification period. If necessary, a dirt
trap suitably located in the heating pipe system
reduces particle sediments. At first install a fitting
piece instead of the flow meter and flush the pipe
system thoroughly. Then close shut-off valves,
remove fitting piece, clean sealing surfaces and
install the flow meter using new gaskets.
