5. Commissioning, operation
With CIP (cleaning in place) we recommend to clean the measur-
„
ing instrument again after mounting, using the process estab-
lished at the operator's site.
EN
With COP (cleaning out of place) we recommend to clean the
„
measuring instrument again before mounting, using the process
established at the operator's site.
On removal from the packaging, and during mounting, particular
„
care must be taken to avoid damage and any mechanical defor-
mation to the diaphragm.
Model PG43SA-S only: Check the zero point. In case of a zero
„
offset, carry out a zero point setting. See chapter 5.7 "External
zero point setting".
5.2 Installation
Do not damage the diaphragm; scratches on the diaphragm (e.g.
„
from sharp-edged objects) are the main causes of corrosion.
For sealing, choose appropriate seals.
„
For flange mounting, only use sealings with a sufficiently large
„
inner diameter and centre them; contact with the diaphragm leads
to measuring errors.
When using soft or PTFE sealings, observe the instructions of the
„
sealing manufacturer, particularly with regard to tightening torque
and load cycles.
For installation, in accordance with the fitting and flange standards
„
the appropriate fastenings, such as screws and nuts, must be
used.
The vent hole at the underside of the case must not be closed
„
(only applies to model PG43SA-S).
