12.6 Refrigeration Plants
The insulation regulations must be observed.
The calculator must generally be mounted separately from the cooling pipe.
12.7 Assembly
The assembly instructions are supplied as standard. Your specifications must
be observed during installation and commissioning.
For temperature sensors with a cable length of more than 3 m, shielded temperature
sensor cables must generally be used. The shielding must be properly connected
to the ground using the supplied mounting clamps.
It must be ensured that all earthing connection points of the overall installation
(mains, external supply, chassis of the flow sensor and calculator) are potential equal.
Ensure correct grounding.
12.8 Lead Sealing
Each calculator must be provided with the necessary seals to protect it against unau-
thorised access.
Safety symbols relevant to calibration must not be damaged or removed! Otherwise the
calibration of the calculator as well as all warranty and service guarantees will expire.
User seals may only be removed by authorized persons in the course of services. They
must be renewed after the service has been completed.
12.9 Service and Repairs
Service and repair work may only be carried out by qualified personnel who have been ex
-
pressly authorized by Sontex.
12.10 Installation Information
The calculator must generally be mounted separately from the heat or
cold pipe.
Ensure that no condensation water can run into the calculator along the
connected lines.
If there is a risk of vibrations in the piping system, the calculator should
be mounted separately on the wall.
For medium temperatures above 90 °C, the calculator should be mounted
remotely.
The flow sensor should be mounted between two shut-off valves.
For the flow sensor, the direction of flow must be observed (arrow on the
flow sensor).
The pipeline must be flushed before mounting the flow sensor to ensure
that there are no foreign bodies in the pipeline.
The lines must be vented during commissioning. Air in system or flow
sensor may affect measurement result
Only use suitable, new sealing material.
The tightness of the various connections must be checked.
Lightning protection cannot be guaranteed; this must be ensured via the
house installation.
All cables must be laid at a
minimum distance of 300 mm
from power
and high-frequency cables.
Radiant heat and electrical interference fields in the vicinity of the
calculator must be avoided.
