The below general principles prior to and after mounting the system shall be
followed.
Requirements for installation environment
HEAT METER has been designed for indoor installation in non-condensing
environments with ambient temperatures from 5~55°C.
The meter must not be under any mechanical stress when installed in the
pipe.
The meter must be protected against pressure shocks in the pipe. The
humidity of the mounting environment shall not exceed 85% (without
condensation).
Protection class IP66 allows short-term submergence, provided that all cable
unions have been correctly mounted and that the plastic cover has been
properly fastened.
Make sure the meter is installed sufficiently far away from possible sources of
electromagnetic interference (switches, electric motors, fluorescent lamps,
etc.).
All control cables must be drawn separately and not parallel to e.g. power
cables or other cables with the risk of inducing electromagnetic interference.
There must be a distance of min. 25cm between signal cables and other
installations.
If two or more meters are to be installed shall be in parallel, the axis-center
distance between two meters shall be at least 135mm minimum.
