PROBLEM
SOLUTION
Heating jacket does
not fit
Make sure that the heating mantle is intended for your vessel. Measure the height and
circumference of your container and compare them with the dimensions of the heating
mantle in the technical data.
Container heater does
not heat
Make sure that the tank heater is connected to a suitable voltage supply. The type plate
on the connection cable shows the rated voltage of the tank heater.
If an error occurs, the heater is switched off and the error is indicated by rapid flashing
(4 Hz). In addition, read the operating instructions of the temperature controller used.
Ground fault circuit in-
terrupter or fuse trips
Check whether the circuit breaker is suitable for the current requirement of the tank
heater. The type plate on the connection cable shows the current requirement.
Inspect the tank heater and the connection cable for damage indicating a short circuit.
Light soiling
of the outside/inside
Use a clean cloth with household detergent to wipe off the contamination. The cleaner
must not contain solvents or abrasives.
If it is determined or can be assumed that safe operation is no longer possible, the tank heater must be put out of op-
eration and secured against unintentional startup. This also includes clear marking.
This case occurs:
• If the heating jacket shows visible damage (e.g. of the outer jacket).
• When the heating jacket no longer heats.
• If the heating jacket has suffered overstressi
ng of any kind where the permissible limits have been exceeded (e.g.
due to storage, transport, assembly, commissioning, operating conditions, etc.).

Service and maintenance
Maintenance and servicing should be carried out at regular intervals in accordance with the standards specified under
"Safety instructions" and the regulations and provisions applicable to the application. The function of the heating
element, the controller and the limiter must be checked and documented at least once a year.
The inspection must be performed after the heating jacket has cooled down to ambient temperature and has been
disconnected from the power supply. The heating jacket should not have any cuts, cracks or stitches. The insulation of
the connection cable must not have any visible damage. The heating jacket should have no accumulations of dirt, oil,
grease or foreign matter. Warning notices and type plates should be undamaged and clearly legible.
Heating jackets in which the heating conductors are visible have been damaged or overheated. They must be taken out
of service immediately and must not be used again.
11.1 Repair
Conversions or modifications to the tank heater may impair its function. Repairs may only be carried out by
qualified personnel. Only original spare parts and accessories may be used.
Do not attempt to repair a damaged tank heater yourself!
Send it to our service department instead
11.2 Return
For returns, we ask that you always decontaminate the heating mantle beforehand, confirm this in writing and en-
close it with the heating mantle as information. If you need a decontamination confirmation form, please contact your
supplier.
