Pay attention to the angular or sharp protrusions in the threads, flanges and measuring tube.
Therefore, it is recommended to wear protective gloves.
The device shall be used in such a way as to minimize the potential for human contact during
normal operation. To avoid the possibility of exceeding radio frequency exposure limits, human
proximity to receivers with integrated antenna should not be less than 20 cm (8 inches) during
normal operation.
Do not expose the meter to the sun and heat sources. Do not attempt to burn the device.
In case of danger of frost, empty the system and, if necessary, remove the meter.
To clean the device externally use a soft cloth and moistened with water. Do not wash with
high-pressure jets or soak the device in water. Avoid contact with oils and solvent. Do not use
alcohol or detergents.
Do not damage the casing of the device. In the event of collisions of blunt objects on the front
of the display, it can be irreparably damaged and lose the IP65 degree of protection. Install in
areas protected against impacts. If the protective casing breaks, contact customer service.
The display turns off. To activate it, press the button on the device. The display remains active
for 60 seconds.
The meter is not suitable for drinking water but is suitable for circulating water in central heating
systems. The quality of the water has to be as specified by the CEN/TR 16911 regulation.
Do not twist, wrap, extend or shorten the cables of the temperature probes and the cable that
connects the electronic unit to the part of the lower-case body.
The thermal energy meter can be installed only in areas protected from frost.
The thermal energy meter must be protected against pressure shocks in the pipeline.
Slowly fill the pipe with water at the end of the installation.
After installing the meter perform a leak test of the system.
Assemble or disassemble the meter only after depressurization of the system.
The meter does not have lightning protection.
Thermal energy meters do not require special protection against electrical interference; howe-
ver, electromagnetic interference must be avoided.
If transmission network interfaces are used, especially when cables are routed outside the
building, use increased protection against electrical interference.
