Foreword
1. Foreword
This operator's manual contains information and procedures for the
safe operation and maintenance of your Wacker machine. In the inter-
est of your own safety and to prevent accidents, you should carefully
read through the safety information, familiarize yourself with it and ob-
serve it at all times.
This operator's manual is not a manual for extensive maintenance and
repair work. Such work should be carried out by Wacker Service or au-
thorized specialists.
The safety of the operator was one of the most important aspects tak-
en into consideration when this machine was designed. Nevertheless,
improper use or incorrect maintenance can pose a risk. Please operate
and maintain your Wacker machine in accordance with the instructions
in this operator's manual. Your reward will be troublefree operation and
a high degree of availability.
Defective components should be replaced immediately!
Please contact your Wacker representative if you have any questions
concerning operation or maintenance.

3. Description
The air dehumidifiers of the AD series are designed for use in rooms
and at locations that can be quickly dried or in which the relative hu-
midity must not increase in an unregulated manner.
The air dehumidifiers of the AD series consist of a cooling circuit and
a fan and condense the water vapor present in the air. This reduces
the relative humidity.
Figure 1 schematically illustrates the function of the machine. The air
drawn in by the fan (3) flows through the air filter (5) and against the
cold walls of the evaporator (6). This cools the air to a temperature that
is under the condensation point. A part of the vapor is condensed and
is collected in the water collection pan (9). Afterwards, the air flows
through the condenser (4) and is heated to a temperature that is slight-
ly higher than the room temperature.

For the most efficient and reliable operation, the humidity should be
between 40 % and 100 % and the temperature between 3 °C and
40 °C.
The moisture meter turns the air dehumidifier on automatically and
turns it automatically back off when the set limit value has been
reached. The control unit (2) turns the defrosting unit automatically on
and off if the operating conditions change. In addition, the machine is
turned off (fan and compressor switch off, control lamp (b) is lit) if a
malfunction occurs or if the machine overheats in a room that is too hot
(Tmax = 40 °C).
Caution
If the room temperature falls below the minimum level (3 °C), the air
dehumidifier does not function. The control lamp (b) will blink.

AD ... Operation
4. Operation
4.1 Installation
Caution
The mains for supplying power to the machine (230 V, single phase,
50 Hz) must be grounded and equipped with a fault current protective
switch.
Set up the air dehumidifier in the middle of the room to be dehumidi-
fied. The air suction side and the air discharge side must not be ob-
structed. The minimum distance from the walls should be 20 - 30 cm.
Do not set up the machine near heat sources (for example radiators,
ovens, heat outlets etc.) or near doors or openings. Doors and win-
dows in the room must remain closed while the air dehumidifier is in
operation.
Caution
Do not place any rags or cloths on the air dehumidifier.
If required, you can conduct the water formed by dehumidification di-
rectly to a drain. To do this, remove the water collecting pan (9) and
connect a rubber hose to the condensate outlet (7).
4.2 Using the machine
4.2.1 Turning the machine on and off
Caution
Always keep the air dehumidifier in the vertical position (during opera-
tion, storage and, with model AD 22, during transport).
To turn on the air dehumidifier, proceed as follows:
* Turn the rotary control (d) of the moisture meter in the clockwise di-
rection to the marking "20 %".
* Set the green main switch (a) to the "ON" position. The fan and com-
pressor are turned on. The control lamp in the switch is lit.
Operation AD ...
wagtx5700000016en.fm 10
Caution
The air dehumidifier is equipped with an automatic safety device. This
is why the compressor is turned on only 1 minute after you have
pressed the main switch (a).
* Turn the rotary control (d) of the moisture meter in the counterclock-
wise direction until you obtain the desired humidity.
To turn off the machine, set the green main switch (a) to the "OFF" po-
sition.
Caution
If the room temperature falls below the permissible level (3 °C), the air
dehumidifier will not function. The control lamp (b) will blink.
4.2.2 Water collecting pan (not for AD 80)
If the water collecting pan (9) is full, the air dehumidifier will switch off.
The control lamp (c) is lit. After you empty the pan, you can restart the
air dehumidifier.
Caution
Before you remove the water collecting pan, disconnect the machine
from the electric power supply. Set the main switch to the "OFF" posi-
tion and pull the power plug from the electrical socket.
Caution
Carefully slide the water collecting pan back into the machine. This
helps prevent damage or inadvertent actuation of the switch connected
to the float.
