HUMIDITY GAUGE
Positioned on the front of the machine. It has a graduated
scale from a minimum of 80% to a maximum of 20% of
relative humidity to be obtained in the room (Fig. 4).
REMOTE HYGROSTAT
CONNECTION
For remote humidistat connection (Fig. 5), remove the
cover connected to the dehumidifier and connect the
remote humidistat (optional). For correct dehumidifier
operation, completely rotate the knob of the humidistat
on the control panel to the max level and set the desired
humidity on the remote humidistat.
HOUR COUNTER
The hour counter is positioned on the front of the machine
and indicates the number of hours the appliance has
worked (Fig. 6).
FIRST IGNITION
Before starting the appliance it must have been in an
upright position (the normal working position) for at least
eight hours.
Failure to observe this instruction could cause irreparable
damage to the compressor.
After eight hours the dehumidifier can be plugged into a
220-240V single-phase grounded socket. The "POWER"
red led must switched on to shows that is correctly
powered. If the "WORKING" led is off, turn the humidity
gauge knob in a clockwise direction until it comes on.
The "DEFROST" led will also come on and after about 5
minutes, the dehumidifier starts. If the green "FULL" led
is on, the dehumidifiers doesn't start. The tank must be
emptied [if present].
IF THE DEHUMIDIFIER DOES
NOT START OR DOES NOT
DEHUMIDIFY
First of all check the red "POWER" led is on. this shows
that it is correctly powered. Otherwise check if the plug
is correctly connected to the energy supply and if power
reach the appliance. If after these controls the light
remains off, take the appliance to the retailer where it was
purchased.
Check the green "FULL" led is off and check the tank is
empty [if present].
Check the red "WORKING" led is on, this shows the
humidity gauge required to be in function. When the
appliance starts after a pause because the set humidity
level has been reached or because the tank has been
emptied [if present], the "DEFROST" led will come on,
besides the two "POWER" and "WORKING" leds. They
will remain on for about 3 minutes when only the fan will
be working and the compressor will be off.
This cycle is repeated about every 45 minutes to defrost
the coil (evaporator). If the "DEFROST" led remains on for
more than ten minutes take the dehumidifier to the retailer
where it was purchased.
If the appliance seems to be working correctly with the
"WORKING" and "POWER" leds on, but no water or
very few is produced, check that the relative humidity in
the room is not lower than 40-45%, otherwise take the
dehumidifier to the retailer where it was purchased.
CONNECTION TO A
DISCHARGE PIPE
This dehumidifier can be connected directly to a fixed
discharge pipe, in this case the tank [if present] is removed
to enable the connection of the pipe to the threaded male
coupling (Fig. 7). For the connection use a pipe with a ¾"
female coupling.
PERIODIC MAINTENANCE
The only maintenance required is cleaning the filter, the
frequency depending on how dusty the room is and how
many hours the appliance actually works each day.
In normal use it is sufficient to clean the filter once a
month, but if the room is very dusty it should be cleaned
more frequently.
The filter is cleaned by washing it under a jet of water in
the sink, flowing in the opposite direction to the air flow:
the perforated front panel must face downwards so that
the water pushes the filter against the panel.
After a few years, the hot heat exchanger (condenser)
could need cleaning using compressed air and only
a qualified technician must do this task. This cleaning
improves the appliance efficiency and guarantees its long
life.
