System operation strategy
This section describes the operation strategy of the adsorption dryer.
The following diagram illustrates the method of operation of the adsorption dryer:
Fig. 4
The room air (= process air) taken in is fed through the turning adsorption rotor. The adsorp-
tion rotor is a high-performance rotor. By its metal silicate coating it has been optimised for
maximum water adsorption under dierent intake conditions. The slow rotation of the rotor
results in an automatic, continuous drying/regeneration process.
Due to its honeycomb structure the rotor features a very large surface. The mechanical
strength of the surface is extremely high. The rotor is non-combustible, maintenance-free and
washable.
The moisture taken up by the rotor is fed back out of the rotor by a heated air current (=
regeneration air) owing in the opposite direction.
The regeneration air is heated by a dynamic, safe and self-regulating PTC heating element.
The moist air current is discharged at the regeneration outlet (see Fig. 1 and Fig. 2) and must
be removed from the room via a hose or air duct (see page 12).

Location, transport and installation
This section contains important information about the necessary operating conditions, trans-
port and installation of the adsorption dryers.
Series AD adsorption dryers are suited for mobile or stationary use on building sites, in stor-
age rooms, cellars, garages, on boats and in caravans. AD adsorption dryers work without
problems in the temperature range from -10 °C to +35 °C and in the humidity range from 10
% to 95 % relative humidity.
In case of connection and operation in accordance with its designated use the device gener-
ates a negative pressure in the operating room. As a result air, particles, smoke or gases can
be drawn in from outside or neighbouring rooms with potentially unexpected hazards due to
the eects on replaces and stoves or other equipment or due to any substances or materials
present there.
Assess this situation before using the adsorption dryer, and take appropriate preventive
measures, for example disconnection of devices or sealing-o of endangered rooms.
The devices must not be used under the following conditions:
• in rooms with potentially explosive atmospheres.
• in rooms with aggressive atmospheres, e.g. ammonia, wood acids, etc.
• in rooms with water with a pH value outside the range from 7.0 to 7.4.
• In case of lower pH values there is risk of corrosion for all metals and risk of damage to
mortar-containing materials (joints). Higher pH values cause skin and mucous mem-
brane irritations and increased lime deposits.
• in rooms with salt or liquids with a salt content > 1% (incl. brine baths).
• in rooms with ozone-treated air.
• in rooms with high solvent concentration.
• in rooms with extreme dust load.
Step Action
1Report any obvious damage to the carrier, parcel service, postal service etc. im-
mediately on delivery and note down the damage on the shipping document or
carrier’s document.
2Remove the packaging material completely and dispose of according to the local
regulations.
3Should any transport damage be detected after unpacking of the device, or
should the delivery be incomplete, contact your salesman in charge or specialised
dealer without delay.

Installation, continued
The dry air can be blown into the room, or one hose or alternatively two hoses can be con-
nected. Follow these steps in order to connect hoses to the dry air outlet.
Step Action Illustration
1 Decide if you want to connect one
hose (option A) or two hoses (option
B). Check if the position of the con-
necting plate for dry air outlet is in
accordance.
2 If the connecting plate has to be turned follow the next steps.
3 Release thumbscrews at the bottom
and top of the connection plate.
4 Turn connection plate.
5 Retighten connection plate using the thumbscrews.
A hose / air duct (not included in the scope of delivery) must be connected to the regenera-
tion air outlet (see position of the regeneration air outlet in Fig. 1 and Fig. 2).
The optimum length of the hose/air duct is 3 – 5 metres.
Step Action Illustration
1 Install the regeneration air hose with a slope away
from the adsorption dryer to prevent that any
condensate probably occurring in the hose cannot
get into the device.
2 If installation with a slope is impossible, drill a hole
(D = 4 mm) at the lowest point of the bend. If water
occurs in the hose due to condensation (in case
of very cold outside conditions) it can drain o
through this hole.
3 Feed the air discharge hose / duct out of the building.

Troubleshooting
This section helps you identifying the cause of an occurred problem and gives advices of how
to solve it.
If problems arise with the adsorption dryer please check the following points. Should the
fault not be located please contact your technical advisor.
Problem Possible cause Remedy
Adsorption dryer does not
work / no air current can be
felt at dry air outlet and at
regeneration air outlet / no
air noise can be heard
Adsorption dryer switched
o
Switch adsorption dryer on
using the On / O switch
Power supply interrupted Check power supply, power
cable, power outlet and
device fuse
The humidity set on the hy-
grostat has been reached.
The adsorption dryer will au-
tomatically re-start when the
set humidity is exceeded.
Air lter clogged Change the air lter (see
page 15)
Rotor drive defective / drive
belt torn
Entrust a specialised com-
pany with the repair of the
adsorption dryer
The desired humidity is not
achieved / the device does
not automatically switch o
although the hygrostat is
connected
The device is not suciently
dimensioned
Ask your specialised dealer
to calculate the capacity re-
quired for your application.
There is very much humidity
in the masonry or in the oor
The adsorption dryer will
need some time to remove
the water and achieve an ac-
ceptable value in the room.
The regeneration air has the
same temperature as the dry
air / the desired humidity is
not achieved.
Heater defective Entrust a specialised com-
pany with the repair of the
adsorption dryer.
The drying performance of the adsorption dryer largely depends on the operating conditions.
Part of the air taken in by the adsorption dryer from the room is discharged from the room
with the regeneration air. As a result, negative pressure builds up in the room which causes
the corresponding amount of outside air to ow in.
The adsorption dryer can achieve very low humidity values in the dry air outlet (at intake
20 °C / 60% r.h. for example about 30 °C / 20% r.h.), but due to the outside air owing in the
humidity in the complete room will never reach the low value of the dry air.
Danger of injury by electric shock and risk of material damage
• The device may only be repaired by trained specialised sta. Within the warranty period,
any work on the dehumidier shall only be carried out by the manufacturer or persons
commissioned by the manufacturer. Any work carried out by unauthorised persons shall
lead to the forfeiture of all warranty claims!
Danger of cutting when reaching into inlet or outlet openings.
Danger of cut injuries at air inlet and outlet.
• Do not reach into the openings; carry the device exclusively by the handle.
