5. Maintenance openings, sealings
C. Rotor Cleaning
Although it is described below, the washing process
should not be performed during normal maintenance.
We recommend to have this work done by the TRO-
TEC Service, or, at least, to call an TROTEC Service
Centre before washing.
1. Operate the air dehumidifier without regeneration
for 15 minutes.
2. Disconnect the power supply (unplug the mains
connector) to prevent the device from being switched
on unintentionally. Injuries which are dangerous to
life may occur otherwise.
3. Dismount the rotor carefully and make certain that
the surfaces are not damaged in this process.
4. Place the rotor in a bath for approximately 30 minutes,
adding a weakly acid detergent or toluol.
5. Flush the rotor using fresh water under low pressure.
6. Drain the liquid from the rotor and blow the structure
of the rotor free using compressed air under low
pressure.
7. Mount rotor and toothed belt carefully.
8. Make certain that all sealings are correctly in place.
9. Start the dehumidifier without including it in the
process and measure its capacity after approxi-
mately 30 minutes.
never use strongly alkaline detergents as they may
lead to the complete deterioration of the rotor.

It is easy to check the dehumidifier function by taking
the temperature at the uninsulated air tubes.
Under normal conditions:
- the dry air outlet is warm (25 - 40 °C) and
- the humid air outlet is warm or hot (30 - 50 °C).
You can proceed as follows if the capacity for dehu-
midification is not satisfactory:
EN
A. Dry and humid air outlets are warm
A1. Check entering humidity and compare with data
sheet. The capacity of the device may be too low
to cope with existing conditions.
A2. Check air flows, filters and reducing damper
adjustment.
A3. Check rotor sealings.
B. Both air outlets are cold.
B1. Is the device switched on?
B2. Has it broken down because of a fault?
B3. Check the regeneration heater.
B4. Check the fan.
B5. Check whether the reducing damper in the rege-
neration channel is not closed.
B6. Check the air filter.
C. The dry air outlet is cold and the humid air
outlet is very hot
C1. Check whether the rotor is turning.
C2. Check whether the reducing damper in the process
channel is not closed.
