Operating Manual – Electric Heaters TEH 200 / TEH 300 / TEH 400 Version 3.0
9
Trotec electric heaters are designed for long hours of operation
with minimum maintenance effort. Safe operation of the device
requires all built-in components, especially the safety
temperature limiter (STB), to be checked and cleaned after 6
months at the latest or after every 4000 operating hours as well
as all damaged components to be replaced.
To clean the inside of the housing, the fan and further electrical
components need to be protected from
water ingress with the appropriate means!
Activities required before starting maintenance
• Do not touch the mains plug with wet or damp hands.
• Wait for the end of the rundown period if the device was in
operation beforehand.
• Switch off the device at the main switch.
• Before any work, detach the mains plug!
Maintenance tasks and repair work may only be
performed by qualified electricians or Trotec.
Cleaning the housing
Clean the device with a soft, damp and lint-free cloth. Ensure that
no moisture enters the housing. Do not use any sprays, solvents,
aggressive cleaning agents or abrasive cleaners. Only use clean
water to moisten the cloth.
Changing the filter
The filter change intervals depend on the degree of air pollution
and the filter quality. Dirty filters impair the performance ability of
the electric heater. Therefore, in case of heavily contaminated
intake air, they are to be inspected at least once a week,
otherwise at least monthly and replaced whenever necessary.
1. Open the weather protection grid by means of the two
handles.
2. Remove the bag filter.
3. Install the new bag filter.
4. Then close the weather protection grid again.
