Automatic defrost
At low ambient temperatures, ice may form at the evaporator
during dehumidification. The device will then carry out an
automatic defrost. Dehumidification is briefly interrupted during
defrosting. The fan keeps running.
Defrosting of the device takes place electronically in air
circulation mode. In defrost mode, the compressor switches off
while the fan keeps running and circulates the compressor's
waste heat around the evaporator for defrosting.
The duration of the defrost process can vary, but it does not
exceed 8 min. Do not switch off the device during automatic
defrost. Do not remove the mains plug from the mains socket.
The FROST indication (25) is illuminated during automatic
defrosting.
Setting the correction value for the room humidity
The ambient conditions might make it necessary to determine a
correction value for the room humidity. This correction value is
always added to or subtracted from the current room humidity
value.
Example: The displayed room humidity is always 5 increments
too high => change the correction value to -5
The correction value's default setting is 0. The correction value
can be set in the range from -9 to +9.
ü The CURRENT indication (21) appears on the display (12).
1. Press the TIMER button (14) for approx. 10 s until an
acoustic signal is emitted.
ð The SET (20) and CURRENT (21) indications flash.
2. Press the arrow buttons (15, 16) to set the desired
correction value.
ð The desired correction value is indicated in the room
humidity segment display (22) for approx. 10 seconds.
Then the current relative room humidity is displayed
again.
ð The correction value has been saved.
Info
Please note that the set correction value also
influences the desired or set room humidity. The
correction value is applied to every room humidity
measurement.

Shutdown
Warning of electrical voltage
Do not touch the mains plug with wet or damp hands.
• Switch off the device.
• Hold onto the mains plug while pulling the power cable out
of the mains socket.
• If necessary, remove the condensation drain hose and any
residual fluid from it.
• Empty the condensation tank, if need be.
• Clean the device according to the Maintenance chapter.
• Store the device according to the Storage chapter.

Errors and faults

The device has been checked for proper functioning several
times during production. If malfunctions occur nonetheless,
check the device according to the following list.
The device does not start:
• Check the power connection.
• Check the power cable and mains plug for damages.
• Check the on-site fusing.
• Check the filling level of the condensation tank and empty
it if necessary. The FULL indication (23) must not appear
on the display.
• Check the condensation tank for correct seating.
• Check the room temperature. Observe the device's
permissible operating range according to the technical
data.
• Wait for 10 minutes before restarting the device. If the
device is not starting, have the electrics checked by a
specialist company or by Trotec.
The device is running, but there is no formation of
condensate:
• Check the float in the condensation tank for dirt. If
necessary, clean the condensation tank. The float must be
able to move freely.
• Check the room temperature. Observe the device's
permissible operating range according to the technical
data.
• Ensure that the relative room humidity complies with the
technical data.
• Check the preselected relative room humidity. The
humidity in the room must be above the selected range.
• Check the air filter for dirt. If necessary, clean or replace
the air filter.
• From the outside, check the condenser for dirt (see
chapter Maintenance). If the condenser is dirty, have it
cleaned by a specialist company or by Trotec.
