Maintenance

Danger! Exchange of turbines or electric components is to be carried out by
authorised personnel or TBH service only! Devices with brushless motors are
maintenance-free.
TBH extraction and filtration systems are equipped with one of three different motor concepts. Brush motors are used for
inexpensive solutions with short daily operation time. Brushless turbines are the most common motors. They offer
maintenance-free continuous operation, high performance and moderate costs. The third concept is a high performance
blower providing high suction performance and low noice level.
Brush motors have to be exchanged after 600-1000 operation hours (significantly dependent on the application case).
This shows by automatic shutting down of the turbine.

Cleaning the Device

Caution! For cleaning the device, the respective protective equipment is necessary to prevent
contamination with potentially health-damaging substances
• Before cleaning the device, it must be switched off and disconnected from the mains
• The housing is coated with a resistant varnish. A damp cloth and common household cleaner will suffice for
cleaning.
• Do not use solvents!
CR series devices or standard V2A systems can also be cleaned with disinfectants and alcohol according to the
cleaning guidelines
• Take care that no water comes in contact with the electrical components or through the ventilation slots
• In case you take off filter modules for cleaning, necessarily take care to not damage the gaskets and of good gasket
seating when starting the system again
• Dry everything with a cloth
Caution! Do not clean filters! Beating or blowing with compressed air will destroy the filter medium.
Pollutants will contaminate the ambiance air.
Exception: Filter cartridges in FP series systems

Filter change

Caution! The seperate filter stages must be checked regularly (at least once/week) and exchanged if
necessary in order to provide constant throughput and prevent damaging of the system. Filter change only
when device is switched off and with the respective protective clothing only!
Please observe:
• Particle filters must not be cleaned, the are exchanged!
