Do not use water to clean the internal parts of the air conditioner.
Exposure to water can ruin the isolation, with the risk of electric shocks.
When cleaning the unit, make sure the switch is off and the power supply is dis-
connected.
4.2.1 - Recommendations for energy savings
Below find simple recommendations for reducing consumption:
• Always and constantly keep the filters clean (see maintenance and cleaning chapter).
• Keep the doors and windows of the rooms to be climate controlled closed.
• Avoid the sun's rays penetrating freely into the room (we recommend using curtains or lowering blinds or
closing the shutters).
• Do not obstruct the unit air flow (inlet and outlet), i.e. in addition to bad performance of the system, it also
affects correct operation and the possibility of irreparable faults to the units.
4.3 - FUNCTIONAL ASPECTS NOT TO BE MISTAKEN FOR ANOMALIES
The following events may occur during normal operation:
1. PROTECTION OF THE AIR CONDITIONER.
a. The compressor will not re-start for 3 minutes after it has been switched off.
- The unit is designed not to blow cold air in HEATING mode, when the internal heat exchanger is in
one of the following conditions and the temperature set has not been reached.
- When heating has just been started.
- Defrosting.
- Low temperature heating.
b. The indoor or outdoor fans stop running during defrosting.
- Frost may form on the outdoor unit during the heating cycle, when the outdoor temperature is low
and humidity is high, which may cause lower heating efficiency or air conditioning.
- If this occurs, the air conditioner will stop heating mode and will automatically activate the defrosting
function.
- The time required to perform defrosting can vary from 4 to 10 minutes, depending on the outdoor
temperature and the amount of frost that has formed on the outdoor unit.
2. WHITE MIST ESCAPES FROM THE INDOOR UNIT
- White mist may be generated due to the large temperature difference between the inlet air and the
outlet air in COOLING mode in indoor environments with high relative humidity.
- The white mist may be generated by the humidity produced by the defrosting process when the air
conditioner re-starts in COOLING mode after defrosting.
3. SLIGHT AIR CONDITIONER NOISE
- A low hissing noise may be heard when the compressor is running, or has just been switched off.
It is the noise of the refrigerant running or stopping.
- A low "squeaking" noise may also be heard when the compressor is running, or has just been
switched off. This is caused by expansion due to the heat or contraction due to cold of the plastic
parts of the unit, when the temperature changes.
- A noise may be heard due to the louvre restoring itself to its original position on commissioning.
4. DUST IS BLOWN OUT FROM THE INDOOR UNIT.
- This is normal when the air conditioner is re-started after a long period of inactivity, or is used for
the first time.
5. A STRANGE ODOUR IS DETECTED COMING FROM THE INDOOR UNIT.
- It is caused by the indoor unit, which releases the odours absorbed by the construction materials,
the furnishings or from smoking.
