Sontex Superstatic 789 Instruction Guide

0739P300-E Installation Supercal 739 EN 17-03-2016 2 Sontex SA, 2605 Sonceboz, Switzerland
Mounting the temperature sensors
The temperature sensor cables are provided with a coloured indicator plate:
-Red for mounting in the pipe on the “hot” side.
-Blue for mounting in the pipe on the “cold” side.
The Supercal 739 is delivered with a cable length of 1.5 m for the temperature sensors.
The temperature sensors form a sub-assembly matching the integrator. The temperature sensor cables must be neither shortened nor lengthened.
The temperatures of use shown on the label must be respected.
A temperature sensor may be fitted directly in the flow meter. The temperature sensors will preferably be fitted directly, in other words one temperature
sensor will be fitted in the flow meter while the other sensor will be installed on the other side of the heat exchanging circuit.
Tightening the nuts of the sensors Ø 5 and Ø 5.2mm with ½ to ¾ turn from the compression of the seal
When the sensor pockets are employed, these must be used specifically for the two temperature sensors and must correspond to the list set out below.
Asymmetrical mounting is also possible. In that case, a temperature sensor will be fitted directly in the flow meter of the energy meter while the other tem-
perature sensor will be fitted on the other side of the heat exchanging circuit in a sensor pocket defined according to the table set out below. To guarantee
accuracy in this type of use, the following conditions must be respected: minimum temperature ∆T
min
≥ 6 K when the minimum flow is less than ≤ 100 l/h.
Make sure that the sensors are mounted until they stall with the bottom of the sensor pocket.

Direct mounting in a T tube
The temperature sensor is on the same level and perpendicular to the pipe axis (DN15, DN20):
Fitting temperature sensors for refrigeration applications
Insulation will only be provided as far as the fixing screw
The temperature sensor fixing screw must not be covered by any kind of insulation. This likewise applies if the sensor is
fixed directly in the flow meter.
Mounting of the integrator for a cooling application
Only the flow meter can be fully isolated. Separate the integrator from the flow meter and fix using the wall support aid
