Checking the earth connection
Check the function of the earth connection frequently
(see the general assembly drawing and the indica-
tions on the product).
Only a specialist company must be commissioned
with inspections.

Insulation
Check the insulation (if present) on components,
containers and piping for damage.
Damaged insulation must be replaced. The insula-
tion strength must be selected according to the tem-
perature and humidity at the place of installation.
Details on the insulation can be found in the P+I dia-
gram.
Caution!
No screw connections must be used
under the insulation if the piping is
insulated. The pipes must be welded.

Check of the tightening torque
on the adjusting elements of
the fixing base.
The tightening torques vary depending on the
strength and size of the screw used. The values for
tightening torques are to be taken from the applica-
ble DIN, unless otherwise specified.
Hint!
The tightening torques for the adjust-
ing elements should be obtained from
the data sheet. The data sheet forms
part of the product documentation.
