Important before installation
The compact thermal energy meter Integral-V UltraMaXX is a
precision measuring instrument approved for individual mete-
ring of thermal energy system and requires careful handling.
Heating water systems operate at high temperatures and pres-
sures and can cause serious injuries if not handled properly.
Therefore the meters may only be installed by qualified and
trained personnel. The pipework must be earthed. A thermal
energy meter must be installed in a manner which complies
with generally accepted codes of practice (e.g. EN 1434-6)
such that measured values can be recorded correctly. It must
be possible to read the meter without any additional aid. It
must also be possible to dismantle the individual components
without any problems in case of device change!
Important points to be read before installation:
■
The energy meter may only be used under the conditions
indicated on the manufacturer's type plate!
■
Comply with the permissible ambient temperature (from
+5 °C to +50 °C) and water temperature for the flow sensor
(max. 90 °C).
■
Sealing the heat meter itself and on the temperature sensor
is important and prevents unauthorised dismantling.
■
Thoroughly flush the pipe system before installing the flow
sensor (foreign bodies in the measurement medium can im-
pair the functioning of the measuring instrument).
■
The calculator unit / flow sensor / signal cables (e.g. tempe-
rature sensor cable) must not be installed close to main po-
wer cables and/or sources of electromagnetic interference
(minimum distance 50 cm).
■
The flow sensor must never be lifted or carried by its con-
necting cable!
■
Do not install the cable on hot pipes.
■
Breaking the meter seals invalidates the validity of the cali-
bration and the guarantee.
■
The casing may only be cleaned from the exterior and with a
soft, damp cloth. Do not use any cleaning agents.
■
Never carry out welding work near the meter.
■
The meter should remain in its original packaging until all
connection, insulation, painting and cleaning work has been
completed.
■
Always install the meter in the position printed on the
manufacturer's type plate (supply or return / hot or cold pipe).
■
The flow sensor can be installed in either the vertical or ho-
rizontal position.
■
The heat meter must be protected against damage caused
by impact or vibration which can occur in the position in
which it was installed. When starting the meter, the stop val-
ves must be opened slowly.
■
The thermal energy meter must not be installed if it falls on
the ground or is heavily soiled etc.
■
Do not shorten the cable between the flow meter and the
calculator and the cables for the temperature sensors or
modify them in any way whatsoever.
■
Threaded connections to the meter must comply in terms of
the nominal diameter DN and pressure PN (as in EN 1092) of
the matching components of the pipework. The meter must
not be subject to excessive tensions caused by the pipes or
fittings. The pipework of the heating or cooling system must
be properly anchored both upstream and downstream of the
heat meter. All bolts, nuts and gaskets used must be de-
signed for the nominal diameters DN, pressure range PN,
the maximum temperature and the maximum permissible
pressure.
■
Discarded electronic devices or batteries contained within
the product must not be discarded in normal household wa-
ste. Dispose in accordance to local government regulations.
■
External cables must be installed in accordance with the
ESD requirements of EN 61340-5.
■
Environmental class C according to EN 1434-1 and E1 and
M1 according to Directive 2014/32/EU.
