7.1 General Safety Considerations during Use
Danger of injury and physical damage!
- Do not let children play with the air
conditioning unit.
The unit is not designed for use by children.
- Do not connect the equipment whilst using
insecticides or pesticides. These could settle
in the unit and harm the health of persons
with allergies to specific chemical
substances.
- Avoid prolonged exposure to cooled air or
extreme temperatures in the room. This
could be a health hazard.
- Do not insert your fingers or other objects in
the air inlets and outlets, or between the unit
slats whilst the unit is operating. The high
speed of the fan can cause injuries.
Danger of injury and physical damage!
Danger of fire and explosion.
- Do not place any heat source with flame in
the equipment airflow. Do not use sprays or
other flammable gases near the air
equipment. This could cause a fire.
-
In the event that any irregularity is detected
(such as a burning smell), unplug the unit
from the mains immediately and contact the
distributor in order to proceed properly. If
you continue to use the unit under these
irregular conditions, it could be damaged and
cause short circuiting or fire.
- Phone a specialist technician and ensure that
preventive measures are implemented to
avoid refrigerant gas leaks. Leaking
refrigerant of a certain density can cause
oxygen deficiency.
Danger!
Danger of electric shock.
Do not handle the equipment with wet or moist
hands.
Warning!
Danger of breakdowns or malfunction.
- Do not place any object on the outdoor unit.

7.8 Emergency Operation and Operation Test
7.8.1 Emergency Operation
Only use this function when the remote controller is
broken or has been mislaid.
In emergency operation the unit automatically selects
the operation modes, Cooling or Heating depending on
the ambient temperature, see Table 7.3.

7.8.2 Operation Test
Only use this function to carry out operation tests when
the temperature is less than 16ºC.
In order to activate:
• Lift the front lid of the indoor unit.
• Keep the emergency operation/emergency test switch
pressed for five seconds.
A beep is heard twice which indicates the start of the
function in cooling mode with the HI (high) airflow
speed.
• Release the switch.
After 30 minutes the function test will end
automatically.

Advice for saving Energy
9
.1
Suitable ambient Temperature
Set the ambient temperature to an appropriate value to
guarantee physical wellbeing, comfort and, in any case,
to comply with the legal standard. Each degree above
this value significantly increases the energetic
consumption.
The temperature must also be suitable for the specific
use
being made of the room: the temperature of empty
rooms and
bedrooms does not have to be the same as
the main room.
9
.2 Eliminating Heat or Cold Sources
In the event that there are any heat (in cooling mode) or
cold (in heating mode) sources that could be eliminated
please do so (e.g. a window or a door which are not
properly closed). This will ensure that the unit consumes
less energy.
9
.3 Operation in Heating Mode (Heat Pump)
Your unit, when operating in heating mode, acts as a
heat pump,
i.e. it takes heat from the outside (via the
outdoor unit) and
releases it inside (via the indoor unit).
Nevertheless, a conventional
heating system produces
heat purely by consuming energy.
Therefore, heating a
room using a heat pump is far more economic that using
conventional heating (radiators, heaters, boilers, etc.).
9
.4
Ambient Temperature when absent
During heating mode, an economic saving is made by
keeping the ambient temperature at approx. 5ºC lower
than the normal temperature. A reduction which exceeds
these 5º C does not provide any further energy savings
since greater heating power is required for consecutive
periods of operation in normal operating conditions.
It is only worth reducing the temperature even further in
the event of prolonged absences, e.g. during holidays.
During winter protection against freezing must be
guaranteed.
9
.5 Uniform Heating
Often in a house only the one room is heated. In addition
to the surfaces which delimit this area, i.e. the walls,
doors, windows, ceiling and floor, the adjacent rooms are
also heated uncontrollably: thermal energy is
unintentionally lost. It is therefore impossible to
adequately heat the room and an unpleasant feeling of
cold is felt (the same occurs when leaving open doors
which separate heated areas and unheated areas in a
limited way).
This is false economy: the heating is on and,
nevertheless, the ambient temperature is not pleasant.
Greater comfort and a more reasonable operating mode
are gained by heating all the rooms in a house uniformly,
taking into account the use being made of each room
(the temperature of empty rooms and bedrooms does
not have to be the same as the main room).
9
.6 Reduction in Consumption during Night Hours
(SLEEP Function)
Your unit has a SLEEP function which allows the
temperature to be modified automatically in relation to
the predetermined values (in heating mode the
temperature decreases slightly; in cooling mode the
temperature increases slightly) during nighttime hours.
Thus, apart from greater comfort being provided there is
also a reduction in electric consumption. For more
details regarding the SLEEP function, please consult
section 7.7.1).
9
.7 Reduction in Consumption with programmed
Operating Time (TIMER Function)
By using the TIMER function you can adjust the
operation start time of your unit. Therefore, it is possible
to programme the operation of your unit to make it
function only when required and thus achieve economic
operation.
9
.8 Appropriate Maintenance of the Unit
A unit in perfect condition operates efficiently, taking
maximum advantage of the energy it consumes. Ensure
that your unit is correctly serviced (for more details
please consult section 10). In particular, make sure that
the filters are kept clean and that the air inlets and
outlets are not obstructed either on the indoor or
outdoor unit.
