DESCRIPTION
DR dehumidifiers have been designed for use in places which have
to be dried quickly or where an uncontrolled rise in levels of relative
humidity cannot be permitted.
DR dehumidifiers reduce the relative water vapour condensation
level in the air.
As you can see in Fig. 1, each unit has a refrigeration circuit and a
fan.The air which is drawn in by the fan (3) passes through the filter
(5) and strikes the cold walls of the evaporator (6) where it cools to a
temperature which is slightly below condensation point. Some of the
vapour condenses and is collected in the water tank (9). Then the air
passes through the condenser (4) and is heated to a temperature whi-
ch is slightly higher than room temperature.

Fig. 1 How the unit works: 1. Air-tight compressor; 2. Control devi-
ce; 3. Helical fan; 4. Condenser; 5. Air filter; 6. Evaporator; 7. Tube fit-
ting; 8. Float; 9. Water tank (Except DR 310).
Best results are obtained at relative humidity levels of between
40% and 100% and at temperatures that range from 3°C to 40°C.
A humidistat automatically controls the unit, turning it on and off
when the desired level has been attained.The electronic control device
(2) automatically starts and stops the defrosting process in accordance
with the workings of the unit. In case of overheating due to malfunction
or if the unit has been used in a place where the temperature exceeds
the maximum permitted limit of 40°C, the control device automatically
blocks the unit, the fan and compressor stop and the control lamp (b)
lights up.
Warning
If room temperature is lower than the minimum permit-
ted value (3°C) the dehumidifier doesn't work and the
control lamp (b) flashes.
Warning
The mains supply to the heater (230V, monophase, 50 Hz)
must be earthed and have a magneto-thermal switch with
differential.
The dehumidifier should preferably be placed in the middle of the
space where it will operate so that the intake and expulsion of air will
not be hindered. It should be at least 20 - 30 cm from any wall. It
should not be placed next to sources of heat such as radiators, stoves
or other heat outlets. It should not be placed near doors or openings.
When the dehumidifier is working all doors and windows must be shut.
Warning
Cloths or coverings of any kind must not be placed on
the dehumidifier when it is working.

If necessary, the water tank can be removed and the water drained
off directly by attaching a rubber tube to the tube fitting (7).
INSTRUCTIONS FOR USE
TURNING ON
Warning
The dehumidifier must be used, stocked and, for DR 120,
transported in a vertical position. Should this not be the
case, the machine will not function properly.
To turn on the unit proceed as follows:
• turn the hydrostat adjusting knob clockwise to 20%;
• turn ON the green switch (a) position "I". The fan and compres-
sor start and the switch lights up;
Warning
The dehumidifier is provided with an automatic security
device which starts the compressor just 1 minute after
the switch (a) is on.
• turn the hydrostat adjusting knob (d) anti-clockwise to the desi-
red relative humidity level.
TURNING OFF
Turn OFF the green switch (a) position "0".
Warning
If room temperature is lower than the minimum permit-
ted value (3°C) the dehumidifier doesn't work and the
control lamp (b) flashes.
THE WATER TANK (Except DR 310)
When the water tank is full the unit stops immediately and the pilot
lamp (c) comes on. The tank must be emptied before the unit can start
working again.
Warning
Before taking out the water tank, turn OFF the main
switch and take out the plug.
Warning
After emptying , put the water tank very carefully back
in its bay so as not to damage or interfere with the swit-
ch which is connected to the float.
MAINTENANCE
Warning
Before any maintenance operation turn OFF the main
switch and take out the plug.
To work efficiently the air filter and the internal parts of the humi-
difier must be cleaned periodically. To clean the air filter apply com-
pressed air or wash with tepid soapy water.
To gain access to the internal parts unscrew the external casing
panels. The internal parts must be cleaned with an aspirator. Take spe-
cial care when cleaning the condenser's and evaporator's ribbed batte-
ries and the fan blades.
TRANSPORT AND MOVEMENT
Warning
Before moving a unit turn OFF the main switch and take
out the plug.
The dehumidifier must not be transported in a horizontal position.
Having wound up the electrical cable, wheel the unit. Must be tilted
as illustrated in Fig. 2.
