In case of two louvres closed, the fresh air flow towards the adjacent room is 50% higher compared with only one louvre
closed (with equal static external pressure).
With an internal relative humidity higher than 70%, only one louvre can be closed.
Fresh air renewal
• The supplementary fan motor for outside air intake has to be
supplied separately and controlled by a bipolar ON-OFF switch
with safety fuses (field-installed).
To adjust the fan motor air flow to the required values it is
advisable to install a speed controller.
Fresh air flow must be less than 10% of the total air flow, to
avoid operating problems.
For fresh air ventilation rates higher than 10%, a primary air
treatment system with separate deflectors is recommended.
• Install an air inlet grille with filter inspection port to prevent
dust and dirt from entering and fouling the indoor unit heat
exchanger.
Filter installation also makes the installation of a duct closing
damper during shutdown periods unnecessary.
Operating test
• Perform the operating test after the units have been installed in
position and the gas leak test has been completed.
• Check all electrical connections (instructions and wiring diagram).
• Insert the batteries into the remote control and leave it OFF.
• Energise the system, turning the power supply ON.
• Press the
and
buttons of the infrared remote control and
hold them pressed for more than 5 seconds. The display will be
cleared, the time segments will display the icon (Src = service test).
When test mode is selected, the unit operates as described below:
• The green LED and the yellow LED blink every 2 seconds.
• The indoor fan operates at low speed.
• The louver operates according to "Auto heat" or "Auto cool"
based on operating mode.
• The system works in Cool Mode at fixed compressor frequency
for 3 minutes.
• The system stops for 3 minutes.
• The system works in Heat Mode with fixed compressor
frequency for 3 minutes or until the indoor coil temperature is
greater than 40°C.

Conditioned air supply to an adjacent room
• Air supply to an adjacent room requires that the outlet
corresponding with the duct is closed, using the air
supply outlet obstruction kit supplied.
An air inlet grille must be fitted (if possible near the floor)
between the air conditioned room (where the unit is situated)
and the adjacent room or, alternatively, the door must be
undercut, as shown in the drawing.
• The duct lengths can be calculated in accordance with the "air
distribution to an adjacent room" diagram, also taking into
account the pressure drop through air diffusers and fresh air
filters.
• DO NOT use active carbon or electrostatic filter kits for ducts
towards adjacent rooms.
During the cool mode and heat mode check the following
conditions:
1. Difference between indoor ambient temperature and indoor unit
air discharge temperature must be greater than 3°C.
2. Indoor fan must operate at low speed.
3. Louver must be in auto heat or cool louver based on operating
mode.
4. No fault code must be signalled by the system.
If one of the above conditions is not positive, please check the
correct installation of the system.
• After test has been completed, press button
control to leave the test menu.
Note:
When 30 minutes have elapsed and no buttons have been
pressed, the remote control will automatically exit the test menu
and resume its normal operation.
