5. Commissioning, operation

Store the instrument in its original packaging in a location that fulfils the conditions listed
above. If the original packaging is not available, then store the instrument in a container
that is similar to the original packaging, so that the instrument can't be scratched and is
protected against damage if dropped.
EN
5. Commissioning, operation
Only use the instrument if it is in perfect condition with respect to safety.

5.1 General mounting instructions

Prior to commissioning, the instrument must be subjected to a visual inspection.
Check the diaphragm for scratches and damage.
■
Leaking liquid is indicative of damage.
■
Sealed screws must not be loosened under any circumstances. Otherwise there is a
■
risk that the system fill fluid may escape, with the result that the measuring assembly
may not function correctly anymore.
Check the seal for contamination and damage and clean or replace it, if necessary.
■
Check the sealing faces for contamination and damage and clean or rework them, if
■
necessary.

5.2 Mounting instructions for diaphragm seal systems with 3-A and EHEDG

Observe the following instructions, especially for EHEDG-certified and 3-A-compliant
diaphragm seal systems.
Make sure that the conditions described in chapter 3.7 "Compliance with 3-A conform-
■
ity" are fulfilled for diaphragm seal systems with 3-A.
Make sure that the conditions described in chapter 3.8 "Compliance with EHEDG
■
conformity" are fulfilled for diaphragm seal systems with EHEDG.
Mount the instrument with minimal dead space and able to be cleaned easily.
■
The mounting position must not form a draining point or cause a basin to be formed.
■

5.3 Requirements for mounting point

The mounting point must meet the following conditions:
Protected from weather influences. Permanent exposure to UV light/sunlight can lead
■
to a change in the colour of the plastic parts and a clouding/yellowing of the status
indication. Therefore, a possible restriction of the visibility of the status indication
cannot be excluded.
Under corrosive ambient conditions (e.g. salty, humid air), restrictions in the gloss level
■
of the metal surfaces, or even corrosion on the instrument, may occur, which make
readability of the product label more difficult.
Sealing faces and seals are clean and undamaged.
