0739P300-E Installation Supercal 739 EN 17-03-2016 6 Sontex SA, 2605 Sonceboz, Switzerland
Coaxial multiple jet meter with G 2’’ connec-
tion
To install the Supercal 739 with coaxial multiple jet with the G2” connection in the EAS base, the
following steps must be respected:
 Flush out the installation pipes carefully in compliance with the DIN/EN standard speci-
fication.
 Close the shutoff valves before and behind the meter.
 Open the drainage valve to reduce the pressure and discharge the water contained in
the pipe between the two shutoff valves.
 Consider the direction of flow circulation (EAS base).
 Remove the blind cover or the old meter from the EAS base using an installation span-
ner. Warning! Water may escape.
 Remove the pre-formed gasket and then clean the contact surfaces and the thread.
 Place the new profiled gasket in the EAS base with the plane surface facing upwards or
the groove in the preformed gasket facing downwards. Make sure that the gasket is
properly positioned.
 Lubricate the external thread (G2’’) of the measuring capsule with a fine silicone coat-
ing.
 Remove the protection cap from the measuring capsule and screw the measuring cap-
sule down firmly by hand. Then tighten as far as the mechanical end stop using a
mounting tool.
 Install the temperature sensor.
 Turn the display into the desired position for reading.
 Check the waterproof of the meter under pressure.
 Seal the measuring capsule and the temperature sensors.
Mounting cable for the pulse input function
The pulse inputs are built with SELV circuits (Safety Extra Low Voltage) and must be only connected with SELV circuits. The electrical characteristics are
displayed on page 12.

General
The compact mechanical single or multiple jet thermal energy meter Supercal 739 is a precision measuring instrument approved for individual metering of
heating systems and must be handled with care.
The Supercal 739 is available in a heating or cooling version and determines the thermal or cold energy exchanged by a heat-bearing fluid in a heat ex-
changer circuit.
The Supercal 739 complies with the requirements of the European Directive MID 2004/22/EC modules B and D and of the standard EN 1434 class 3.
Important!
The energy meter may only be used under the conditions indicated on the manufacturer’s rating plate!
In the event of failure to comply with these instructions, the manufacturer declines all liability.
The seals must not be removed or may be removed only by authorised persons.
If these conditions are disregarded, the factory warranty and the calibration will no longer be the manufacturer’s responsibility.
The manufacturer will not be liable in the event of any modification of the metrological data or of the measurement parameters if the manufacturer’s seal is
damaged.
For cleaning, a moist cloth is sufficient. Do not use solvents.
Use only accessories provided by the manufacturer.
Do not shorten the cable between the flow meter and the integrator and the cables for the temperature sensors or modify them in any way whatsoever.
Before installation
Check the installation data and compare them with the specific 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 electri-
cal fields near the integrator and connection cable.
As a rule, the integrator must be installed at a distance from pipes carrying refrigerating fluids.
Action must be taken to ensure that no condensation water can penetrate inside the integrator.
If there is any risk of vibrations, the integrator must be installed separately on the wall.
If the specific temperature of the fluid within the flow meter regularly reaches 90°C, the integrator must be installed separately from the flow meter.
It is advisable to drain the installation before fitting the flow meter. This will enable any foreign body to be 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 fire, keep out of reach of children.
Advice on disposal:
In order to maintain and protect the environment, to reduce waste of natural resources and prevent pollution, the European Commis-
sion has established guidelines according to which manufactures must take back electrical and electronic devices in order to forward
them to a regulated disposal or recycling system.
If you dispose of the batteries yourself, enquire about the possibilities of recycling in your region.
