This condition ensures cooling of the ambient air.
To set this mode of operation, using the MODE button, you have to wait for the COOL LED to turn
on.
Initially the LED flashes to respect the pause of the compressor, although continuous ventilation
from the two ducts is always guaranteed. Respecting the timing, the device is activated to reach the
set temperature. The start is also made evident by the fixed ignition of the COOL LED.
Upon reaching the desired temperature, the unit goes into stand-by mode, during which the COOL
LED flashes and the only air flow from the two ducts is guaranteed again.
During all these stages it is always possible to change the ventilation speed from the air ducts.
This condition ensures a heating of the ambient air.
To set this mode of operation, using the MODE button, you must wait for the HEAT LED to turn on.
Initially the LED flashes to respect the pause of the compressor, although continuous ventilation
from the two ducts is always guaranteed. Respecting the timing, the device is activated to reach the
set temperature. The start is also made evident by the fixed ignition of the HEAT LED.
Upon reaching the desired temperature, the unit goes into stand-by mode, during which the HEAT
LED begins to blink and the only air flow from the two ducts is guaranteed again.
To always ensure maximum yield, if the ambient temperature is below 15 °C, the fan, if it is set at
maximum or minimum speed, will autonomously decrease the speed. This condition will be signaled
by the fact that the HIGH or LOW LED starts blinking.
This condition ensures continuous ventilation in the room.
To set this mode of operation, using the MODE button, you must wait for the VENT LED to turn on.
Remove the packaging taking care not to damage the unit. Dispose of the packaging products
(wood, plastic, cardboard) and send them to be specialized collection or recycling centres (follow
local regulations in force.
All units are assembled and wired at the factory. Upon receipt of the unit, it must be inspected
immediately, carefully checking that it has not been damaged during transport or that there are no
missing parts; any complaints must be notified to the carrier and the factory or his representative
within 8 days.
Before use, check in particular that there are no dents on the external metal
panels, including those of the tank compartment. Also check that the cable, plug
and relative insulation are intact. Otherwise, it is FORBIDDEN to connect and
start the unit, which must be sent to an authorized service centre.
The operating range is shown in the data sheet at the end of the manual.
Warning: It is strongly recommended to operate the unit within the limits set out in the "technical
and performance data" table. Overcoming these limits does not guarantee either the normal
operation or the reliability of the group or even the integrity (for special applications, please contact
our office).
