Immediately after receipt, you should check your air dryer for transport damage! In the
case of damage, you should inform the forwarding agent, parcel service, post office etc.
accordingly upon receipt, and make a note of it on the forwarding documents!
If a transport damage should be stated after unpacking the equipment, please contact
immediately your respective seller.
Before putting your air dryer into operation for the very first time, these instructions for
operation should be studied very thoroughly. Thus, you can make sure that this appliance
will operate perfectly for a long period of time saving yourselves unnecessary repairs and
expenses.
In the case of technical unclarity or faults disconnect your appliance and ensure that it is
not connected again by taking the mains plug out of the socket.
Please, keep the device wrapping in order to be able to send the device safe for
guarantee repair. In order to save place you open simply the adhesive tape with a
knife and you fold the carton.
2 Design of equipment and mode of functioning
The DH-air dryer is constructed exclusively for air drying in closed rooms. That dehumidifier
can prevent the formation of sweating water, eliminate too high air humidity and hold a specific
air humidity unchangeable. The time which the dryer requires in order to achieve a specific
humidity depends essentially on the environmental conditions. The attainable humidity value is
equally dependent on the environmental conditions.
The DH-dehumidifier works according to the condensation principle with heat recovery. The
fan (partial positions see detail drawing) suck the moist air through a cool register
(evaporator). The air becomes so far chilled under the point of condensation here, that the
steam of air condense as water and flows into the water-collecting tank. The chilled and dried
air is warmed up at the condenser again. Through the heat pump effect, the outlet air is some
degrees warmer than the sucked room air. Vigour profit can conducted up to 3-fold of the
electrical power consumption. The absolute moisture of air is lowered continuously by the
continuous circulation of the room air through the device. The surplus moisture is removed
takingly and efficiently.

The condensation dryers AD 520 and AD 620 are furnished with protective devices. The
devices were subjected to a safety examination. Dangers threaten in the case of operating
error or abuse
- for the user.
- for the machine and other real values.
- for the efficient work of the machine.
All persons who have to do with the list, initiation, service and maintenance of the devices
must be qualified correspondingly and consider this operating manual precisely.
Using as directed
The condensation dryers are intended for the drying of air with atmospheric pressure.
Risk by accessory
Hoses for condensate removal and air filters must be fit expertly and must not take the
protective devices of the condensation dryers out of operation. The control elements must
always remain freely amenable.
Authorized users
The service of the condensation dryers AD 520 and AD 620 may only be carried out by
persons, that were instructed from the operator . The user is responsible in the field of action
third parties compared to.
Responsibilities for different activities on the device must of course be determined and kept.
Unclear competences are a safety hazard.
The operator must make the operating instruction amenable for the user and make sure that
the user did understand the manual.
4 Installation and transport
The DH-dehumidifier is planned for the mobile effort and wall mounting on a wall bracket
(optionally available). During the setting up and transportation of the dehumidifier, the
following items are to be considered:
¾ That dehumidifier must be installed so that the air can circulate without obstruction
through him. The air filter and also the lamellae of the front wall must not be covered. The
open space before the lamellae and the air filter must at least conduct 1 meter.
¾ Before every local alternation of the device, switch off the device at the on/off-switch, pull
the power plug from the socket and empty the water tank!
¾ The air dryer must be moved only using the provided roll resp. handle systems!
¾ The air dryer must be installed on a plane base only, as otherwise it must be secured
against rolling off!
¾ That dehumidifier can be transported standing or lying! The standing transportation is to
be preferred if possible.
¾ The appliance must be used exclusively for air drying.

5 Electrical connection
Before connecting the air dryer, the following items must be checked:
9 Does the mains voltage coincide with the voltage of the appliance?
9 Adequate fusing of socket and supply system?
9 Has the required residual-current-operated circuitbreaker (r.c.c.b) been installed in case of
swimming baths?
9 If a cable drum is used: has it been unwound completely?
9 Is the appliance connector suitable for the building socket?
9 Is the socket provided with a perfect grounding?
Attention!
Before putting the air dryer into operation, the technical data of the appliance should be
compared to the conditions prevailing in the room of installation!
6 Operation
6.1
Putting into operation
Attention!
Before putting the air dryer into operation, the instruction manual should be studied carefully.
Thus, damages by a false or inappropriate operation as well as by inadequate environmental
conditions can be avoided.
For using the air dryer, please proceed as follows:
9 After having been transported, the air dryer should rest for abt. 15 min. During this period
of time, the oil distributed inside the refrigerating system and frothed during transport will
return into the compressor. We recommend this procedure since it extends the service life
of the compressor.
9 Put the plug into the socket.
9 Check whether the bucket is inside the equipment resp. whether the drain hose has been
fastened and laid appropriately.
9 Switch on the appliance at the hygrostat.
9 Set the required humidity value at the hygrostat (please refer in this respect to 'Hygrostat
Control').
9 If the existing humidity is higher than the set value, the air dryer will start to operate.
9 If the existing humidity is lower than the set value, the air dryer will not start to operate.
6.2
Hygrostatregelung
The air dryers of the DH-series dispose of a hygrostat for setting the required humidity value.
The hygrostat is placed at the upper side of the unit. It makes that the air dryer cuts in as soon
as the ambient humidity exceeds the preset value. If the humidity value falls below the set
value, the hygrostat will switch off the appliance.
The following operating modes can be set by means of the hygrostat:
¾ The marker of the knob points at position "O" the device is switched off. It is not drying.
¾ The marker of the knob points at the field with one drop: The device is working. When
achieving a humidity of approx. 70% r.h. (relative humidity) the unit will switch off.
¾ The marker of the knob is between the field with one drop and the field with two
drops: The device is working. When achieving a humidity of approx. 50% r.h. (relative
humidity) the unit switch off .
¾ The marker of the knob shows onto the field with three drops: The device is working.
When achieving a humidity of approx. eliminate 40% r.h (relative humidity) the unit will
switch off.

The marker of the knob points at position "max": the device is in continuous
operation
Attention!
The marks at the rebound curve and the humidity values mentioned above are to be seen as
reference values only. The hygrostat of the air dryer and a hygrometer located inside the room
to be dried most probably will not indicate the same values. It is recommended to change the
setting at the air dryer until the desired room humidity has been reached.
6.3
Condensate outlet
The air dryers of the DH-series are serially equipped with water collecting tanks and with
fittings for 12 mm hoses. If the water collecting tank is used, the appliance will switch off
automatically when the tank is full, and the red pilot lamp will light up.
Attention!
The device switches itself off automatically during withdrawal of the water tank. It will only
starts working again if the bucket adjusted be properly (swimmer on the bucket must osculate
the microswitch in the device). If the device will not start immediately, the bucket should be
moved a little in the device.
If a hose is used for the draining the condensate, it should be proceeded as follows:
9 Remove the bucket from the bucket compartment.
9 At the bucket you find a connecting piece . Bore a hole into that connecting piece. Avoid
injuries!
9 Screw the connecting angle on that connecting piece of the bucket. Don´t forget the
sealing.
9 In the door of the dryer is a pressed sector. Open this sector to put the hose through after
putting back the bucket into the dryer.
9 The bottom of the hose must go downwards to leave the unit.

The end of the hose must be situated lower than the beginning of the hose (runoff socket)!
The hose must never be bent!
No objects must be placed onto the hose!
Automatic defrosting
During air drying, ice may form at the evaporator. The volume of ice depends on the ambient
conditions prevailing in the room to be dried. The air dryer is equipped with an automatic airdefroster. It ensures that, depending on the extent of ice formation, the appliance will be
defrosted automatically according to the following principle:
¾ A temperature sensor measures the condition existing in a critical area of the evaporator.
¾ It transmits the signal for defrosting.
¾ The compressor switches off and the fan runs further.
¾ The ice is thawed with ambient air.
¾ Subsequently, the air drier will operate again in the normal air-drying mode.
¾ Operating conditions
Air driers of the DH-series are suitable for application on closed and heated rooms. DH-air
dryers can be operated within a temperature range from +5 to 32°C and with a relative
humidity of 40 to 100 %. An optimal working is achieved at temperatures from 15 °C and
more.
Attention!
The appliance must not be used under the following conditions:
¾ in rooms of potentially explosive atmosphere
¾ in rooms of aggressive atmospheres, for example ammonia and wood acid
¾ In rooms with water which shows a pH-value outside of 7,0 to 7,4. Remark: In the case of
lower pH-value, corrosion occurs at all metals and damages occurs at mortar containing
materials. In the case of higher pH-value, it comes to irritation of skin and eye mucous
membrane and extreme lime deposits.
¾ in rooms featuring a high concentration of solvents
¾ in rooms of an extremely high ratio of dust´.
In the case of doubtful operating conditions it is recommended to contact the Technical
Department of Messrs. AERIAL or a specialized dealer.
Using an AD-air dryer under inadequate operating conditions will entail that the
warranty becomes null and void!

The dryer does not receive air
sufficiently. Clean the filter and/or
install a new one. A soiled air filter
can in the long run lead to
disadvantages at the dryer. Tipp:
Control the filter regularly.
In the case of these conditions,
the capacity of DH-types is very
small on account of the design of
the refrigeration components and
the automatic defrosting. We only
recommend DH series for heated
rooms with temperatures >= 15°C.
