Electrical heater VEEK
overheating
Proceed as follows if the overheating protection
with manual resetting trips:
1. Intervention in the electrical heater, such as
removing the cover, must only be performed by
an authorized installer.
2. Disconnect the current
3. Carefully investigate the reason for tripping of
the overheating protection.
4. Once the fault has been corrected, the over-
heating protection can be reset.
Check the following:
1. Is the filter dirty or blocked?
2. Has any fire damper tripped?
3. Is the automatic system (damper function, time
relays, etc.) functioning as expected?
4. Is the fan working?
Filter service
The VEKA unit with an electrical heater requires
regular servicing of the filter in order to function
without problems.
A contaminated filter can cause tripping of the
overheating protection. See the care instructions for
the VEKA unit under the point ”Replacement of fil-
ter”. The electrical heater element is of the rod type,
which reduces the risk of contamination. The unit
should be cleaned internally, therefore, in conjunc-
tion with filter replacement or every six months.
