5. Commissioning, operation
The instrument is vented to the atmosphere. Therefore, no coating or other covering
■
may be applied which might restrict the venting.
5.4 Mechanical mounting
The instrument may only be installed and mechanically mounted by skilled personnel.
Mounting is only permissible in the depressurised state. Reliably depressurise the
process connection using the available valves and protective devices (e.g. shut-off valve,
monoflange).
WARNING!
Physical injuries and damage to property and the environment caused
by hazardous media
Upon contact with hazardous media (e.g. oxygen) and also with refrigeration
plants and compressors, there is a danger of physical injuries and damage to
property and the environment.
Media with extremely high temperature and under high pressure or vacuum
may be present at the instrument.
▶
For these media, in addition to all standard regulations, the appropriate
existing codes or regulations must also be followed.
▶
Wear the requisite protective equipment.
WARNING!
Risk of burns
On opening the process connection, there is a risk of dangerously hot media
escaping.
▶
Let the process connection cool down sufficiently before installing it!
The installation of the instrument must be carried out in accordance with the specifica-
tions of the respective process connection. Other installation types, e.g. direct welding,
are not permissible and are considered as improper use.
Remove the protective cap of the instrument not until shortly before installation.
■
Avoid any contact with or mechanical loading of the diaphragm. Scratches on the
■
diaphragm (e.g. from sharp-edged objects) are the main causes of corrosion.
Seal the process connection.
■
- Select a suitable seal.
- Centre sealing on the sealing face.
- The diaphragm movement must not be limited due to the sealing.
Use appropriate clamps for the existing clamp connection and mount them in accord-
■
ance with manufacturer's instructions.
