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 con-
densation level in the air.
As you can see in figure 1, each unit has a refrigeration
circuit and a fan.The air which is drawn in by the fan (3) pas-
ses 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 con-
denses and is collected in the water tank (9). Then the air
passes through the condenser (4) and is heated to a tempe-
rature which is slightly higher than room temperature.

Best results are obtained at relative humidity levels of
between 40% and 100% and at temperatures that range
from 3° to 40°.
A humidistat automatically controls the unit, turning it
on and off when the desired level has been attained.The elec-
tronic 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 auto-
matically blocks the unit, the fan and compressor stop and
the control lamp (b) lights up.
Warning
If room temperature is lower than the mini-
mum permitted value (3°C) the dehumidifier
doesn't work and the control lamp (b) flashes.

Warning
The mains supply to the heater (230V, mono-
phase, 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 dehumidi-
fier 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 DR120, 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 "1". The fan and
compressor start and the switch lights up.
Warning
The dehumidifier is provided with an automa-
tic security device which starts the compres-
sor just 1 minute after the switch (a) is on.
• Turn the hydrostat adjusting knob (d) anti-clockwise to
the desired relative humidity level.
TURNING OFF
Turn OFF the green switch (a)-position "0".
Warning
If room temperature is lower than the mini-
mum permitted value (3°C) the dehumidifier
doesn't work and the control lamp (b) flashes.
