sealed gas-tight.
o
Comply with relevant regulations regarding electric installation and
regulations for prevention of accidents.
o
Pneumatic connections, connection lines, and fittings must with-
stand the excess pressure that may occur over the entire tempera-
ture range.
o
Before entering inspection chambers, the oxygen content must be
tested and the inspection chamber flushed if necessary.
o
When using metallic connection lines, proper equipotential bond-
ing must be ensured; alternatively, electrical isolators must be
used.
5.2 Assembly of the Leak Detector
o
Wall mounting using the supplied mounting material.
o
Outside of the potentially explosive area (zone 1 or 2), also applies
to the connection lines and interstitial space.
o
Plastic housing:
In a dry room
Stainless steel housing: Outdoors, without additional protective
box
o
To avoid excessive heating, the leak detector must not be installed
directly next to a heat source.
The ambient temperature must not exceed 60°C; appropriate
measures may need to be taken (e.g., installation of a roof to pro-
tect against sunlight).
o
Ventilation systems must be kept clear.
o
Do not mount in access or inspection chambers.
