User instructions – Adsorption dehumidifier TTR 400/400D/500D
Caution!
Damage to the device due to improper handling.
Cleaning, maintenance and repair of electric and
mechanical components may only be carried out by
trained personnel or the Trotec customer service.
Replacing the filter
The intervals for replacing the filter depend on air contamination and
filter quality. Contaminated filters affect the efficiency of the dehumidifier.
For this reason, filters should be checked and cleaned or replaced once
every week (daily on construction sites) if necessary.
Danger!
Risk of injury at the fan.
Before removing the air filter, the device must be
switched off and secured against accidental activa-
tion, particularly if the fan inlet is freely accessible!

1 Filter cover
2 Filter mats
To remove the filter mat (2), the filter cover (1) must be released by pulling
it with a slight jerk.
By default, all devices are equipped with a reusable filter mat (PPI30).
This mat can be cleaned by beating or washing it.
Caution!
Damage to the device due to liquids.
Before inserting the air filter, always ensure that it
has dried completely. Otherwise, there is the risk
that the fan takes in liquids and is damaged due to
a short circuit.
12. Dangerous substances
When operating the dehumidifier in rooms that are contaminated by cer-
tain chemical substances, the dehumidification unit (rotor) may be dam-
aged permanently. The substances remain in the rotor and may deterio-
rate the performance of the device by clogging the silica gel pores or lead
to chemical reactions of the gel.
This permanently affects the performance and service life of the
dehumidifier.
For this reason, it must be ensured, that the applied dehumidification
agent, i.e. the silica gel, cannot come into contact with dangerous sub-
stances. The following list includes substances with a proven deteriorat-
ing effect on the dehumidification rotors (silica gel) used in this device.
Even small quantities of these or similar substances must be prevented
from coming into contact with the device.
