4. Safety instructions
Keep away from children: Do not allow children to
play with, or around this unit. It may result in injury.
Be sure the unit is inaccessible to children when they
are unattended.
Keep unit grounded: Always operate the unit with a
grounding plug and a grounded electrical outlet. A
grounding plug is an essential safety feature that
helps reducing the risk of shock or fire.
Protect power cord from damage: Never operate the
unit with a damaged power cord, as this may lead to
electrical or fire hazards. If the power supply cord is
damaged, it must be replaced by a cord of the same
type and specifications.
Place on stable surface: Always operate the unit on a
stable, level surface, to prevent it from falling and
cause injury.
Keep away from water: Never operate the unit in
pooled or standing water, as this contains a risk of
injury due to electrical shock. Do not store or operate
it outdoor. If electrical wiring or components become
wet, thoroughly dry them before using the unit.
Keep air intakes clear: Do not clog or block air
intakes, which may occur if operated too close to
draperies or similar materials. This may cause the unit
to overheat and result in a fire or electrical hazard.
Keep filters clean: Always use clean air filters. Do not
allow any material to clog the filter, as this may cause
the dehumidifier to overheat. Do not allow oil, grease,
or other contaminants to be drawn into the
dehumidifier.
Keep Electrical Components Dry: Never allow water
inside the dehumidifier's electrical components. If
these areas become wet for any reason, thoroughly
dry them before using the dehumidifier.
ATTENTION !
This dehumidifier must not be used in rooms under
the following conditions:
- Potentially explosive atmosphere
- Aggressive atmospheres
- High concentration of solvents in the air
- An extremely high ratio of dust

5. Functional principle
This dehumidifier is designed to reduce humidity from
the air in a building or part of a building. The purpose
is to prevent humidity damage, and to dry out wet
materials such as carpet, carpet cushion, floors, walls,
furniture, contents, lumber, and structural materials.
This dehumidifier can avoid the formation of
condensate, eliminate high air humidity and keep
constant a certain humidity value. The time necessary
for the dehumidifier to dry a room and to reach the
air humidity level desired strongly depends on the
environmental conditions prevailing at the site of
installation of the appliance. The dehumidifier
functions according to the condensation principle with
heat recovery. The fan takes in the humid air through
the evaporator. Here the air is cooled below the dew
point so that the water vapor present in the air
condensates and flows into the water collecting tank.
The cooled and dried air is heated again at the
condenser. By the permanent circulation of the
ambient air through the appliance, the absolute
humidity is decreased continuously.
6. Automatic defrosting system
During normal dehumidifying operation, ice may form
on the evaporator. This dehumidifier is equipped with
an automatic hot-gas defrosting system and if ice is
detected by the temperature sensor, it will defrost
automatically according to the following principle:
-A temperature sensor measures the condition
existing in a critical area of the evaporator.
-It transmits the electrical signal for the
defrosting system. It has been designed to
avoid a frequent defrosting of the
dehumidifier.
-After some time the relay will switch off the
fan and simultaneously open a solenoid valve.
-Now, hot gas is channeled into the evaporator
until the latter is completely free of ice.
-Subsequently, the dehumidifier will operate
again in the normal mode.
7. Set up and transportation
Regarding set up and transportation the following
instructions have to be followed:
-Make sure, that the air filters as well as the
gratings, which are situated on the sides of the
dehumidifier, are not covered!
-Before moving the device to a different location,
switch it off using the mains switch! Unplug the
cable and empty the water tanks (see 13.)!
-Place the dehumidifier on a level surface! If that
is not possible, secure it against rolling away!
-Always transport the dehumidifier in an upright
position!
-If, for any reason, the device has been positioned
horizontally for even a few minutes, let it stand
upright for at least 30 minutes afterwards, before
switching it on again. This allows the oil to run
back into the compressor.
ATTENTION !
The device must only be transported in an upright
position. Small inclines when moving it with the
wheels are uncritical. Bigger inclines should be
avoided.
In case the device has been transported in a
horizontal or strongly inclined position, it must rest
upright for at least 30 minutes prior to putting it
back into operation.
Before you move the device make sure that:
-the power cord has been unplugged,
-no water is left in the water tanks,
-the dehumidifier has rested for at least 5
minutes prior to transport.

8. Operation
1) On/off switch
Puts the device into the standby mode and turns it
back on.
2) LED „ON“
The LED „ON“ lights up, when the device is supplied
with electrical power.
3) Control for relative humidity
Using the buttons „+ % RH“ and „– % RH“ you can
preset the desired level of relative humidity.
Upon pressing either of these buttons the display
switches from showing the actual value to showing
the set value. Shortly after the desired value has been
set, the display switches back to the current value.
You can adjust the desired value between 31-90 % rel.
humidity. Once this value has been reached the
device automatically switches off.
The dehumidifier switches on when the set value has
been exceeded by +1 and switches off when the value
falls below the set value by -2. The minimum running
and pause times of the compressor is 1 minute each.
When you preset a level of 30% relative humidity the
device will run in continuous operation and will not
switch off even when this value has been reached.
4) Fan speed selector
The DEHUMID HP 50 can run with two different fan
speed stages.
When you change the setting the display will show the
selected fan speed stage. After a short period of time
it switches back to showing the current humidity
value.
Stage 1: High performance
The fan is running at maximum speed.
We recommend this setting when you
desire a high and rapid
dehumidification.
Stage 2: Low performance
The fan is running at reduced speed
and therefore especially silently.
However, the dehumidification
performance is also being reduced.
5) LED „water tank full“
When the LED „FULL“ lights up the water tanks are
either full or not inserted properly. The device then
switches off automatically.
Empty the water tanks (see 13.) and make sure to
correctly put them back into the dehumidifier. After a
short period of time the device will then resume
operation.
When removing the water tanks during operation the
device will sound a bleep and stops running.
When the LED „FULL“ flashes, the device is set to
operate with direct drain.
6) Display
By default the display shows the current actual
humidity level.
When changing the fan stage it shows the selected
stage.
When changing the desired humidity value the display
shows that value.
If there is an error regarding the radio signals it shows
„Code 05“.
When the device has been cut off from the mains the
display will show the current software version upon
first activation.
After a short period of time the display always
switches back to the current humidity level.

9. Radio operation
The dehumidifier is available with or without a radio
sensor.
An error in radio reception (no reception for 10
minutes) will be signaled in the display by the error
code „05“. This code „05“ is also being displayed after
every activation of the device until it receives a valid
radio signal.
ATTENTION !
Never try to repair the device in case of
malfunction!
Otherwise you will forfeit your warranty claim and
risk damage to persons and the device.
Never intervene into the refrigerant circuit. This
must only be done by qualified personnel.
This device contains the cooling agent R-407C.
It must not be allowed to escape into the
atmosphere.
10. Overheating protection
If the compressor heats up to more than 80°C during
operation it is being shut off and only re-engaged
once it has cooled down to 50°C.
11. Keylock
To prevent accidental input and to protect the device
from unauthorized access it is equipped with a
keylock.
To activate this keylock hold down the buttons „+ %
RH“ and „- % RH“ simultaneously for about 5 seconds
until an acoustic confirmation. During activation the
display shows „88“. To release the lock repeat this
process.
When a key is being pressed while the keylock is
active the display again shows „88“.
12. Operating hours counter
The DEHUMID HP 50 is fitted with an operating hours
counter.
It is located on the back of the humidifier, above the
water tanks.
It measures the time in hours during which the device
is in operation.
13. Emptying the water tanks
Once the water tanks are filled to their maximum the
device will stop to operate and on the control panel
the LED „FULL“ lights up.
In addition an acoustic warning signal will sound (3
times for 1 second). This will be repeated every 5
minutes for a total of 60 minutes, when the acoustic
warning will be shut off.
To put the device back into operation you have to
perform the following steps:
-Remove the water tanks from the device. (The
water tanks are located on the back of the
device.)
-Empty the water tanks completely.
-Replace the water tanks back into the device.
Now the LED „FULL“ will go out and after a short
period of time the device will resume operation.
14. Operation with direct drain hose
You can operate the DEHUMID HP 50 without the
water tanks, using a direct drain hose.
To activate the drain mode follow these steps:
-Remove the water tanks (on the backside)
-Turn off the device
-Unplug the mains
-Hold down the button „fan speed selector“
while plugging the mains back in.
The magnetic switches are now deactivated, which is
indicated by the flashing LED „FULL“.
The device is now in direct drain mode and you can
operate it with the drain hose.
As soon as the water tanks are being re-inserted, the
drain mode is automatically being deactivated for
safety reasons.
ATTENTION !
Make sure that the dehumidifier cannot be
operated without a drain hose, once the magnetic
switches have been deactivated, damage may occur.

15. Maintenance
ATTENTION !
Always pull the mains plug before doing any
maintenance work!
Never try to repair the device in case of
malfunction!
Otherwise you will forfeit your warranty claim and
risk damage to persons and the device.
Contact your retailer instead.
1) Cleaning the device
Use a damp cloth for cleaning the casing. Do not use
aggressive cleaning agents.
Make sure that no water gets into the device, since
otherwise damage to it may occur.
That is why you should never directly use a jet of
water to clean the device.
2) Cleaning/replacing the filters
There are two air filters located on the sides of the
dehumidifier, one each for the intake and the exhaust.
They filter out dust and other particles of the ambient
air and thus must be cleaned regularly.
The air filters should be cleaned as necessary but at
least once a month.
In order to remove the filters you should follow these
steps:
-Remove the grating by
unscrewing the screws
(located as shown)
-Then remove the clamp
bracket on the back of
each grating by gently
bending it outwards
-You can now remove the
filter from the grating
-Clean the filter by blowing it out / vacuuming it
off or sluicing it down if applicable.
-In case cleaning the filter is not possible /
sufficient or if the filter is damaged you should
replace it.
