CONDENSATE DRAINAGE
INSTALLATION TIPS!
1) If possible use copper pipes.
2) The supply and return pipes have the same diameter (1/2”).
3) The pipes must always be lagged.
4) The condensate drain hose is plastic and has a Ø 16.5 mm fitting.
5) The fan coil heat exchanger is fitted with a manual air valve at the highest
point. Use a screwdriver on this valve to bleed the system, thereby ensuring
correct circulation of the water.
6) To prevent broken pipes, avoid sharp bends. Bend pipes with a radius of
curvature of at least 70 mm.
7) If a pipe is bent repeatedly in the same point it could break. Replace with an
undamaged pipe.
Periodically check the condensate drain hose for dust or fluff, which could cause
clogging with consequent overflow of condensate. Install traps on the drain line
to prevent unpleasant odours rising from the drainage system.
No foreign matter must be allowed to deposit in the condensate collecting tray
(if installed).
Any foreign matter whatsoever MUST be removed and the drain hose CLE-
ARED before starting the appliance.
Wrap the thermal insulation of the connecting pipe over that of the unit pipe and
bind them together with vinyl tape, ensuring that there are no gaps.
CAUTION!
THE UNIT CONDENSATE DRAIN HOSE IS OF BASIC IMPORTANCE FOR
SUCCESSFUL INSTALLATION. LAG THE PIPES ADEQUATELY AND COR-
RECTLY!
It is advisable to lag the water pipes and the condensate drain hose with fabric
tape to prevent any dripping on the outside.
Wrap vinyl tape around the electric connecting cable and fix it onto the water
supply pipe.
CAUTION!
Ensure that the cable is perfectly insulated to prevent possible infiltration
and consequent short circuit or fire.

HEATING (HEAT)
- Use this function to cool the room.
- Set a temperature on the thermostat. The cooling function does not work if:
a) the thermostat is set with a lower temperature than the room temperature;
b) the water temperature isn’t higher to 38°C.
1 When the fan speed is set on “AUTO”, operation in the cooling mode is as
follows:
DEHUMIDIFYING (DRY)
- This function has to be used only in case that the valve for opening/closing the
water flow is installed on the unit.
- This function has to be used only with cool water in the unit, in order to dehu-
midify and to cool the room.
- The control system can manage the fan automatically, for removing humidity
from the air. When the fan starts to run, it will work until the set temperature is
reached, then cycles of fan starting / stopping will alternate.
FAN
- This function has to be used only in case that the valve for opening/closing the
water flow is installed on the unit.
- This function can be activated with any water temperature of the unit
- This function has to be used just for moving the air in the room. The fan speed
can be manually controlled.
NOTE: after approx. 0.5 seconds the whole display reappears. When the
speed is set to AUTO: the fan speed changes according to the difference
between the room and the set temperature. When this difference has de-
creased the fan speed is reduced.
AUTO
DO NOT USE IT, as it could cause unit malfunction.
CHANGING THE FAN SPEED
Press the SPEED button. Each time the button is pressed the fan speed chan-
ges in the following sequence:
2 When the fan speed is not set on “AUTO”, operation in the heating mode is
as follows:
Press the POWER ON/OFF button.
Use the DIREC (airflow direction) button on the remote control to adjust the
airflow direction upwards or downwards (the right-left direction is changed by
moving the flaps by hand).
WARNING!
- Do not insert fingers or other objects into the louvers as there is a high-speed
fan inside the unit which could cause injury to persons or damage to property.
- Do not switch on the fan coil with the louvers locked as this could cause mal-
function.
- Never position the motor-driven louvers manually.
AUTOMATIC
- PRESS THE AUTO BUTTON
The louver swings automatically between the positions of maximum and mini-
mum aperture, thereby preventing stratification in the heating and cooling mo-
des of operation. Press the DIREC button to stop automatic operation.
- PRESS THE DIREC BUTTON
Every time the DIREC button is pressed the louver changes the direction of the
airflow (5 different positions). If the DIREC button is kept pressed down, the
positions change continually until the button is released.
There may be a short delay after having pressed the DIREC button before the
louvers change position.
NOTE
- Always use the DIREC (airflow direction) button on the remote control to chan-
ge the up and down position of the louvers. Do not try to position the louvers by
hand as this could cause malfunction. In the event of malfunction, switch the fan
coil off and then on again to restore correct louver operation.
- In the cooling and dehumidifying modes of operation, condensation could form
around the unit and drip from the air outlets if the louvers have been set in an
unsuitable position for such modes. This position must only be used for a short
time.
- When the system functions are stopped, the up and down louvers automatical-
ly move until the air outlets are closed.
1 When the appliance is switched on, the louvers open, carry out a com-
plete swing and then stop on the previously set position.
2 When the AUTO button is pressed:
a. the louvers swing downwards and open as far as they can. This action resto-
res the set angle.
b. the louvers swing 35° upwards in the cooling mode and 10° in the heating
mode.
c. the louvers swing 45° downwards in the cooling mode. In the heating mode
the louvers move back 10° from the angle initially established after the first 5
swings.
3 When the DIREC button is pressed the louvers swing by 10°:
a. The louvers swing downwards and open as far as they can to. This action
restores the set angle.

INSTALLATION, OPERATION
AND MAINTENANCE MANUAL
NOTE
- Before cleaning the unit ensure that it is switched off and disconnected from
the power supply.
- There is a high-speed fan inside the unit that could cause injury.
- When the unit is not used for a long time (one month or more), have the unit
operate in the fan mode for approx. half a day, if possible when the weather is
fine, to ensure that the internal parts are dry.
- When the unit is not used for a long time, disconnect it from the power
supply.
- Diesel oil, petrol, insecticides and other chemical agents could damage the
unit.
- Do not spray inflammable products on the unit.
- Clean the unit with a cloth moistened with hot or cold water and then wipe dry
with another soft, clean and dry cloth.
- Depending on the conditions of use, the internal parts of the unit become dirty
after 2 or 3 seasons and its efficiency could be affected. It is therefore advisable
to carry out the recommended maintenance. Contact the authorised after-sales
service.
Remove the cover
1 Use both hands to pull the lower edge of the front cover outwards by
approx. 30°.
2 Use both hands to push and raise the front cover.
3 Lift the cover upwards until it can be removed (the grille cannot be removed
unless it is raised sufficiently).
CAUTION!
In the event of malfunction (smell of burning or other), stop unit operation imme-
diately, cut off the power supply and contact the authorised after-sales service.
Switching off the unit does not disconnect the unit totally from the power supply.
Always make sure that the on/off switch is therefore put to off to ensure that the
unit is fully disconnected from the power supply.
IT IS NORMAL THAT...
During operation and immediately after the system has been switched off, water
can be heard running inside the unit pipes.
During operation creaking sounds may be heard caused by expansion of the
front cover due to the change in temperature.
The unit could give off odours coming from the furniture, tobacco and other
things present in the room.
During operation in the cooling and dehumidifying modes a very fine mist may
come from the unit. This is due to the sudden cooling which produces conden-
sation and consequently the mist.
The fan could turn slowly during operation in the dehumidifying mode or when
the unit is controlling the room temperature.
In the automatic operation control, the fan turns very slowly.
Cleaning the front cover
Use a vacuum cleaner to remove accumulated dust. Clean the grille with a cle-
an cloth moistened with water and then wipe dry with a clean dry cloth.
Mounting the front cover
Fit the hooks located at the top of the cover into the relative holes and then close
the cover by rotating it downwards until it locks into place
If the air filter is dirty the airflow could be reduced and consequently unit efficien-
cy with an increase in noise. Clean the filters at the beginning of each season
and when the unit is used frequently. Clean the filters once every two weeks.
Removing the air filter
1 Remove the front cover.
2 Gripping the filters firmly by their frame, pull them slightly upwards until freed
from the two catches located at the bottom and then pull downwards to remove
them.
Cleaning the air filter
Use a vacuum cleaner to remove the dust accumulated on the filters or wash
them in a solution of neutral detergent. If washed, let them dry in a shady place
before replacing them in the unit.
Installing the air filter
1 Align the filters with the drain duct on the panel and press them in as far as
they will go.
2 Insert the two filter lugs into the relative holdfasts.
3 Close the cover.
