2. Security

Improper installation, pressure tests, modications or incorrect

operation can cause personal injury and damage to property.

Pressure surges in the pipeline can damage the meter!

Existing air pockets falsify the measuring result.

 If the seal is damaged or removed, the compact thermal energy meter is no longer approved

for legal metering or legal measurement.

 Before installation, check compact thermal energy meter for transport damage.

 Do not drop, never hold on to the protective cover of the counter.

 If the compact thermal energy meter has been dropped, it must not be installed again.

 Only use suitable lubricants for seals.

 Compact thermal energy meters may only be installed after a pressure test.

 Compact thermal energy meter may only be installed in pipelines that have already been

leak-tested, rinsed and must be well vented before commissioning.

2.1 Personnel qualication

The compact thermal energy meter may only be installed or replaced by qualied personnel for

sanitary, heating and air-conditioning technology.

2.2 Intended use

WARNING

NOTICE

The compact thermal energy meter Superstatic 749 is a precision

measuring instrument approved for individual metering of heating

systems and must be handled with care.

The Superstatic 749 is available in a heating or cooling or heating/

cooling version and determines the thermal and/or cold energy

exchanged by a heat-bearing uid in a heat exchanger circuit.

The Superstatic 749 complies with the requirements of the European

Directive MID 2014/32/EU modules B and D and of the standard EN

1434 class 2.

The thermal energy meter must be used within the conditions indi-

cated on the meter; the metrological seals have to stay intact.

In the event non compliancy to these instructions, the device may

be destroy and the manufacturer declines all liability, warranty and

guarantee for correct metrology.

The manufacturer will not be liable in the event of any modication

of the metrological data or of the measurement parameters if any

of manu-facturer’s seals is damaged. The seals can only be applied

by authorised people in conformity to national legislation related to

legal metrology.

Use only the accessories provided by the manufacturer.

For cleaning, a moist cloth is sufcient. Do not use solvents.

Do not shorten the cable between the ow meter and the calculator

and the cables for the temperature sensors or modify them in any

way whatsoever.

6Instruction for use | Superstatic 749

Before installation

 Check the installation data and compare them with the specic

characteristics of the thermal energy meter.

 The rules for installation and those relating to the project must be

respected.

 The environmental temperature range for the energy meter

is 5...55 ºC.

 Make sure that the meter and the labels can be read easily.

 All connections must be made at a minimum distance of 300 mm

from high frequency or high voltage cables. Avoid thermal

radiation and interfering electrical elds near the calculator and

connection cable.

 As a rule, the calculator must be installed at a distance from

pipes carrying refrigerating uids.

 Action must be taken to ensure that no condensation water can

penetrate inside the calculator.

 If there is any risk of vibrations, the calculator must be installed

separately on the wall.

 If the temperature of the uid within the ow meter regularly

reaches 90°C, the calculator must be installed separately from the

ow meter.

 It is advisable to drain the installation before tting the ow

meter. This will allow that any foreign body is withdrawn from the

pipe.

Security with lithium batteries

3V lithium batteries are used. Certain security rules must be respected:

the replacement of batteries or to add a second battery is not allowed.

During recycling, the following points must be respected:

Do not recharge or short-circuit, protect against humidity, do not

expose to heat, do not throw batteries in re, keep out of reach of

children.

5. Installation

The prescriptions related in the standard EN1434-6 must be respected when the

Supestatic 749 is installed.

In the standard version, the calculator is parameterised by default for installation on the “cold”

pipe side. Installation on the “hot” pipe side must be specied with the order.

Depending on version and use (heat and/or cooling meter), the energy meter must be tted on

the “cold” or “hot” pipe side of the installa-tion in compliance with the chosen conguration. If

the device was ordered with the conguration option, some parameters can be changed using

the “Cong” menu during commissioning.

In a same installation, mixed mounting positions (horizontal and vertical) can be realized.

Place the ow meter correctly according to the direction of the uid (an arrow  can be seen

on the ow meter).

Horizontal mounting with the integrator facing downwards is not permitted. Also avoid tting in

a position which may cause an air bubble to build up inside the mechanical meter.

The energy meter must be tted between two shutoff valves. The ow meter must be installed

ahead of any monitoring valves so as to avoid any potentially interfering inuence. Waterproof

will be checked at the various mounting points.

The heat conveying liquid must be equivalent to water without any additives according to

standard FW510 of the AGFW (German District Heating Association). If additives are added to the

water, the user must ensure the compatibility of the materials used in the thermal energy meter

which are in contact with these additives.

5.1 Mounting of the calculator for a cooling application

Only the ow meter can be fully isolated. Separate the calculator from the ow meter and x

using the wall support aid.

It is recommended to separate the calculator from the ow meter and installed at a sufcient

distance from the ow meter if:

- The meter has to be installed in a conned space

- The meter is in connection with mounting in condensing environments

- To prolong the battery life time

The pipes are generally free from air before the installation is brought into service. Follow the

insulation instructions for cooling installations. Final commissioning must be performed and

documented.

Horizontal mounting position:

The sensor head MUST be placed to the side

+/- 45° in relation to the pipe axis to avoid

inuences of air inclusions (top) or dirt (bottom).

Vertical mounting position:

Mounting in riser or down pipes possible.

After mounting and before commissioning purge system > 10 min at qp to

avoid air bubbles.
