BIEMMEDUE DR Serie Manual Para El Usuario Y El Mantenimiento página 13

Before using the space heater, please read carefully all the instructions for use described below and follow the
indications scrupulously.
The manufacturer cannot be held responsible for damage to persons and/or property caused by improper use of the
equipment.
This instruction manual is an integral part of the equipment and must therefore be kept carefully and passed on with
the unit in the event of a change of ownership.
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.
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 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°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
permitted 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:
EN
IMPORTANT
• turn the hydrostat adjusting knob clockwise to 20%;
• turn ON the green switch (a) position "I" .The fan and
compressor 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
desired relative humidity level.
TURNING OFF
Turn OFF the green switch (a) position "0".
Warning
If room temperature is lower than the minimum
permitted 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 switch 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
humidifier must be cleaned periodically. To clean the air filter
apply compressed 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 special care when cleaning the condenser's and
evaporator's ribbed batteries 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.
