high humidity , moisture, combustible gases, vapours and solvents.
• Never expose the product to mechanical stress.
• If safe operation is no longer possible, take the device out of service and secure
it against unintended use. Safe operation is no longer possible, if the product:
- has visible damage,
- no longer functions properly ,
- has been stored under adverse ambient conditions for an extended period of
time or
- has been exposed to considerable strain during transport.
• Please handle the product carefully . The product can be damaged if crushed,
struck or dropped, even from a low height.
• Also observe the safety and operating instructions of any other devices that are
connected to this product.
• If you have doubts about how the product should be operated or how to safely
connect it, consult a trained technician.
• Maintenance, adjustment and repair work may be carried out only by an expert or
a specialist workshop.
• If you have any questions that are not answered in these operating instructions,
please contact our technical customer service or another specialist.
b) Connection and Operation
• The product‘s design complies with protection class I. Only an earthed mains
socket connected to the public power supply may be used as power supply to
the product.
• The mains socket into which the plug-in thermostat is plugged must be easily
accessible.
• The plug-in thermostat is equipped with a child safety device. Only when the
prongs of the interconnection are placed in both openings of a front socket at the
same time will the child-lock mechanism release the opening.
Nevertheless, take special caution when children are around. Children are not
aware of the potential danger associated with the incorrect handling of electrical
appliances. There is a risk of a life-threatening electric shock!
• The product is only intended for use in dry indoor locations. No part of the product
should become damp or wet; never handle it if your hands are wet! Never set up
the product in the direct vicinity of a bathroom, shower , bathtub or similar. There is
a risk of a life-threatening electric shock!
• Use the product only in a temperate climate, never in a tropical climate.
• Do not operate the device in environments where there are high levels of dust,
ammable gases, vapours or solvents. There is a danger of re and explosion!
• Never operate the plug-in thermostat in a vehicle.
• Do not connect the product to the power supply immediately after it has been
transferred from a cold room into a warm one (e.g., during transport). The conden-
sation that forms might destroy the device. Moreover , there is danger of electric
shock! Allow the product to reach room temperature. Wait until the condensation
has evaporated. This might take several hours. Only after this should the product
be plugged into the power supply and put into use.
• Never pull out the plug-in thermostat by pulling on its cable when disconnecting it
from the front socket of the humidity controller . Always pull the plug out of the front
socket by gripping the area provided for this purpose on its sides.
• Do not overload the plug-in thermostat. Observe the connected load in the chapter
„T echnical Data”.
• Always unplug the plug-in thermostat from the mains socket before cleaning it or
when the device is not be used for a long time.
• Never pour any liquids above or next to the product. Y ou run the risk of causing a
re or a fatal electric shock.
If any liquid has still happened to enter the device, immediately turn off the power
supply to the plug-in thermostat to which the table fan is connected (turn off the
fuse/circuit breaker/residual current operated circuit breaker of the associated cir-
cuits). Only then can you unplug the plug-in thermostat from the mains socket and
contact a specialist. Do not use the product any longer .
• Do not connect in series! This can lead to overloading of the plug-in thermostat!
There is a risk of re!
• Do not operate while covered! At higher connected loads, the plug-in thermostat
will get hot, which may lead to overheating posing a risk of re, if it is covered!
• Only voltage-free, when the plug is unplugged!
• If the plug-in thermostat is damaged, do not touch it; there is a danger to life from
electric shock!
First, switch off the mains voltage to the socket, to which the plug-in thermostat
is connected (switch off at the corresponding circuit breaker or remove the safety
fuse or switch off at the corresponding RCD protective switch, so that all poles of
the mains socket are disconnected).
Then you can remove the plug-in thermostat from the mains socket. Don’t use
the damaged plug-in thermostat any more, dispose of it in an environmentally
friendly way .
