MOTOR FAN GROUP
Single-inlet centrifugal fan with statically and dynamically balanced plastic
impeller. The 3-speed electric motor, made to international standards,
has an overload cut-out and the run capacitor always connected. The
motor is directly coupled to the fan and cushioned with flexible mountings.
It is particularly efficient
and low noise.
DÉCOR PANEL
The décor panel has an innovative design so that the appliance may
be used in both dwellings and business premises. The white (RAL 9003)
panel is made in lightweight but strong plastic. Fixing to the load-bearing
structure is quick and easy. 4 adjustable louvers ensure best air
distribution throughout the room. Central intake grille with filter for
cleaning the air. The grille may be removed to access internal parts
without having to remove the panel from the ceiling.

ATTENTION!
Catch up the cassette on the four
corners. Don't lift or move the unit
through the exchanger pipelines or
the exhaust pipe condense.
!
- to fix the panel only use the four supplied screws. Do not use other
kinds of screws or you could damage the condensate drain pan.
- Do not bend or narrow the unit piping.
- Do not remove the cap from the unit piping until immediately before
connecting the pipes.
- To prevent deformation of the air intake grille, do not overtighten the
screws.
CHANGE OF AIR AND RECIRCULATION SYSTEM
- Side knockouts allow connection of a duct for fresh air intake and for
conditioning an adjacent room.
- Remove the external prepunched anti-condensate insulator and
remove the knockout panels using a punch.
FRESH AIR RENEWAL
Remove the polystyrene partition and insert the baffle plate.
Use material purchased locally that is suitable for continuous operation
with temperatures of 60°C. The ducts may be in flexible polyester (with
steel spiral core) or in corrugated aluminium lagged with anti-condensate
material (fibreglass 12±25 mm thick). Upon completion of installation,
surfaces that have not been insulated may be covered with anticondensate insulating material (e.g.: 6 mm thick expanded neoprene).
Failure to comply with these instructions could cause dripping due
to the condensate; the manufacturer cannot be held responsible
for any damage. Any additional fan for external air intake (installer's
responsibility) must be connected to the terminal block as per the
enclosed diagrams. Fan operation is in parallel to the damper
(electrothermal control valve), so that it stops when the valve closes.
Install an air inlet grille on the outside, with an inspectable filter holding
frame to prevent the entry of dust and leaves, which could irreparably
obstruct the unit heat exchanger coil.
RECEIVING, STORE AND MOVING THE UNITS
At the moment of the delivery of the unit, make sure that it corresponds
to the one indicated on the transport document. Check the integrity of
the packing and the unit. Should there be any differences with the original

ATTENTION!
1) Ducting air to an adjacent room requires the closure of at least
the corresponding duct end.
2) When valves are installed, the air ducts to the "D" adiacent
room are unusable (pict. 13).
!
ATTENTION!
- Always use suitably sized wrenches to fix or slacken the water
pipes.
- It is essential to insulate pipes, valves and connections correctly
in order toavoid the formation of condensation, which could
drip into suspended ceilings causing considerable problems.
The water connections are fixed to the unit body to avoid damage when
pipes are connected. It is advisable to tighten the connection with a
wrench. The upper coil connection is fitted with an air valve and the
lower connection with a drain valve, suitable for a 10 mm wrench or
screwdriver. (The coil is only partially drainable; it is advisable to blow
air into the coil for complete drainage)
INSTALLATION OF AUXILIARY DRAIN PAN
a) Remove the plastic cap from the condensate drain outlet on the
water cassette. Do NOT push the cap into the cassette. Fit the
nozzle into the hole (auxiliary condensate drain pan outlet).
b) Fix the auxiliary drain pan to the unit using the relative screws
provided in the kit, ensuring that the condensate pan is level
There is the possibility of draining water from 200 mm above the
level of the unit. To drain the condensate at a higher level, install
condensate drain pump with collecting tray and float valve. A float valve
is recommended to stop the flow of water in the event of pump failure.

SECOND PART:
FOR THE USER
RECCOMENDATION FOR THE USER
Read the precautions carefully and carry out the procedures correctly
- In case of failure or malfunction, always apply to authorised
service personnel. Any attempt to remove parts, or to maintain the
appliance can expose the user to danger of electrical shock. The
cassette does not contain parts on which maintenance can be carried
out by the user.
- In case of relocation, apply to service personnel authorised to
carry out this operation as well as the new installation
- Do not insert fingers or objects of any kind into airflow outlets
or air intake grilles. There is a fan inside the appliance, which turns
at high speed and could cause severe personal injury. Pay particular
attention to children.
- Do not allow the cold airflow to blow on you directly for long
periods of time. Direct and prolonged exposure to cold air can be
dangerous for your health. Pay particular attention to rooms where
there are children, elderly or sick people.
- In case of air conditioner malfunction (e.g. smell of burning), stop
appliance operation immediately, release the dedicated automatic
switch and apply to authorised service personnel. Prolonged use
of the appliance in these conditions can cause fire or electrocution.
- During installation of the appliances, avoid letting children or
disabled have access to the working area. Accidents can occur.
- Install the appliance and the remote control at least two metres
away from television or radio units and from lamps that could
irradiate them directly. Any interference of radio signals can cause
operating problems.
- Do not block or cover the airflow intake and delivery grilles.
The obstruction of these openings causes a reduction of the operating
efficiency of the water cassette, with consequent possible failure or
damage.
- Do not use the water cassette for applications such as the storage
of foods, plants, precision equipment or works of art. The quality
of the objects that are stored could deteriorate.
- Do not expose animals or plants to the direct airflow from the
appliance.
Prolonged direct exposure to the cold airflow from the water cassette
can have a negative effect on animals and plants.
- Do not direct the airflow of the air conditioner towards fireplaces
or other heating appliances. An airflow directed towards the fire can
cause incorrect combustion and fire.
- Air the room occasionally while using the appliance. An insufficient
change of air can cause an insufficiency of oxygen in the room.
- Do not allow the air conditioner to come into contact with water.
The electrical insulation could be damaged with consequent possible
risk of electrocution.
- Check installation conditions in order to identify possible
damage. After prolonged use, apply to specialised service personnel
to control the installation conditions of the air conditioner.
- Do not use flammable gas near the air conditioner.
- Always use the appliance with the air filter installed. Using the
air conditioner without the air filter can cause an excessive
accumulation of dust or deposits inside the unit, with consequent
possible malfunctioning.
- Release the automatic switch if the unit is not going to be
used for long periods of time.
- Remove the batteries from the remote control if it is not going
to be used for a long period of time. Remove the batteries in order
to prevent possible problems caused by loss of electrolyte. In case
of accidental contact of the battery liquid with the skin, eyes or mouth,
wash the affected part immediately with plenty of water, and see a
doctor.
- Please shut off the unitONLY using the ON/OFF switch (infrared
or wall-mounted remote control). If you shut off the unit without
using the ON/OFF switch (ex. change between cool and heat) the
condensate pump stops and the overflowing risk is possible.
!
FAILURE TO COMPLY WITH THE INSTALLATION INSTRUCTIONS
GIVEN IN THIS MANUAL RELIEVES THE MANUFACTURER OF
ALL AND ANY LIABILITY. INCORRECT INSTALLATION COULD
CAUSE MALFUNCTIONING OR FAILURE OF THE APPLIANCE.
IT COULD ALSO REPRESENT A HAZARD FOR THE USER.
WATER CASSETTE OPERATION
The water cassette has been designed to create the ideal climatic
conditions for the comfort of the occupants of the room. It can provide
fully automatic cooling, dehumidifying and also heating. The air is drawn
in by the fan through the intake grille in the front panel and then passes
through the filter, which retains the dust. The air then proceeds through
the fins of a "heat exchanger": this is a finned coil, which cools and dries
or heats the air. Finally the fan sends the air into the room; the direction
of the outgoing airflow can be adjusted by means of the motor-driven
direction louver.

COOLING When the MODE button is pressed and COOL is selected,
the cassette cools the room and at the same time reduces the humidity
in the air. To start the cooling cycle, use the TEMP buttons
and to
set a temperature which is lower than the room temperature. For example:
if there is a temperature of 28°C in the room, a temperature lower than
27°C should be set in order for the compressor and cooling to start. The
appliance automatically adjusts operating cycles in order to keep the
room at the required temperature. Upon completion of settings, press
the SEND button and listen for the beep to make sure that the appliance
has received the command.
I.R. REMOTE CONTROL OPERATIONS
FAN When the MODE button is pressed and the FAN mode is selected,
the cassette will operate as an electrical fan only
DEHUMIDIFYING When the MODE button is pressed and the DRY
mode selected, the cassette alternates cooling and fan cycles. This
mode is used to dehumidify the air without excessively altering the room
temperature.
Operation is fully automatic: the appliance itself controls the fan speed.
HEATING When the MODE button is pressed and the HEAT mode is
selected, the cassette will heat the room. To start the heating cycle, use
the TEMP buttons
and to set a temperature which is higher than
the room temperature. For example: if there is a temperature of 18°C
in the room, a temperature higher than 19°C should be set in order for
the compressor and heating to start. Upon completion of settings, press
the SEND button and listen for the beep to make sure that the appliance
has received the command.
AUTOMATIC OPERATION Access this mode by pressing the MODE
button. In the AUTO mode the electronic control automatically selects
the operating mode according to the room temperature (measured by
the built-in sensor):
- if the room temperature drops below 18°C, the appliance will start the
heating cycle. This will continue until the temperature rises to above
20°C;
- if the room temperature is above 26°C the appliance will start the
cooling cycle. This will continue until the temperature drops below 24°C.

WALL-MOUNTED CONTROL OPERATIONS
Self-diagnosis
The system comes with a self-diagnosis circuit to monitor the
microprocessor functions. In the event of malfunction this circuit
automatically resets the microprocessor.
System memory
The system stores the set parameters (such as the operating status,
fan speed, etc.) in its non-volatile storage. After a power failure, the
cassette will automatically resume operation with the same parameters
that were set prior to the blackout (except the SLEEP and TIMER modes
which will be erased). Any change to the parameters will be saved in
the non-volatile storage after 5 seconds.
Situation of normal operation
The POWER indicator light is on if the cassette was switched on via the
I.R. remote control.
The TIMER indicator light is on if the AUTO START and AUTO STOP
modes are active.
The SLEEP indicator light shows the temperature compensation during
the SLEEP mode.
Situation of alarm
1) The POWER, SLEEP and TIMER indicator lights blink continuously.
The system is protected by the cutting off of power to all the outputs.
This type of alarm is generated by one events:
a) Condensate drain pan float:
Remedy: check the condensate drainage circuit (pump, float, drain hoses).
2) The SLEEP indicator lights blink continuously. This type of alarm
is generated by one events:
a) Coil water temperature above 80 °C.
Remedy: check coil water temperature.
3) POWER indicator light blinks continuously. This type of alarm is
generated by two events:
a) When 3 minutes have elapsed from the start of the COOL or DRY
cycles, coil temperature is above 25° C. The system is protected by
the cutting off of power to the valve output.
Remedy: check the coil water temperature and correct valve operation.
b) When 3 minutes have elapsed from the start of the HEAT cycle, coil
temperature is not above 20° C. The system is protected by the cutting
off of power to the valve output.
Remedy: check the coil water temperature and correct valve operation.
4) TIMER indicator light blinks continuously (fig. 44 A):
Air temperature sensor and water temperature sensor are damaged
or not connected.
5) TIMER indicator light blinks intermittently (fig. 44 B): the filters
must be cleaned.
When the cassette has been operating for more than 500 hours, a
warning is displayed as a reminder to clean the filter.
N.B. Reset by cutting off the power for at least 10 seconds.
CONDENSATE DRAIN PUMP OPERATION SPECIFICATIONS
Cool Unit in operation: the pump operates continuously until the set
temperature is reached; when 3 minutes have elapsed from the start of
the cycle, if the water reaches the float and opens its contact, the unit
instantly shows an alarm through the fast blinking of the indicator lights
Con the panel (the power is cut off to all the outputs). Unit switched off
by remote control, or with set temperature satisfied, or within 3 minutes
preceding cycle start: when the water reaches the float, its contact opens
and activates the pump for 3 minutes; when the 3 minutes have elapsed,
if the float does not close its contact again (water drainage), the unit
shows an alarm (fast blinking of the indicator lights).
Dry As for cool.
Heat - Unit in operation or switched off by remote control: the pump is
never activated.
If Ti<23°C, fan is OFF.
If 23<Ti<35°C, fan runs at minimum speed
If Ti>35°C, fan runs at setted speed.

TIPS FOR BEST USE
- Connect the cassette to a dedicated power socket protected by a
magnetothermal circuit breaker of suitable capacity for the electrical
input of the appliance.
- When the water cassette starts or stops, especially in the heating
mode, creaking sounds may be heard. This is caused by thermal
expansion of the unit parts.
- Mist may sometimes be produced by the cassette for a few seconds
in the cooling mode. This is quite normal and is caused by the
difference in temperature between the air flowing out of the appliance
and the air in the room.
- Do not place heat sources near to the cassette as this could deform
the plastic parts.
- Do not insert objects into the air intakes or outlets when the cassette
is in operation.
- Do not place objects in a position that may obstruct the passage of
the air into the unit as this could affect appliance efficiency.
ENERGY SAVING
- Do not open or close doors and windows too often. Constant
exchange of heat with the outside affects the working of the appliance.
- Do not set too high a temperature (in the heating mode) or too low
(in the cooling mode).
- Do not install the appliance where it is exposed to direct sunlight.
- Use the TIMER for the timed switching on of the appliance, to avoid
the cassette operating needlessly while you are out of the house.
- Use the SLEEP function during the night.
ROUTINE MAINTENANCE
