Relative humidity of the room lower than 80%. If relative humidity is higher than this value, the
air conditioner may generate condensation. Set the air flow of the vertical louver to its maximum
angle (vertically on the floor) and set fan mode to HIGH.
To further optimize the performance of your unit, do the following:
• Keep doors and windows closed.
• Limit energy usage by using TIMER ON and TIMER OFF functions.
• Do not block air inlets or outlets.
• Regularly inspect and clean air filters.
3.4 - 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.
• DO NOT set the unit to excessive temperature levels.
• Set a timer and use the built-in SLEEP/ECONOMY mode if applicable.
• If you don't plan to use the unit for a long time, remove the batteries from the remote control.
• Clean the air filter every two weeks. A dirty filter can reduce cooling or heating efficiency.
• Adjust louvers properly and avoid direct airflow.
• Closing curtains during heating also helps keep the heat in.
• Doors and windows should be kept closed.
4 - OPERATIONS AND MAINTENANCE
4.1 - OPERATION MODE SELECTION
While two or more indoor units are simultaneously operating, make sure the modes do not conflict with each
other. The heat mode claims precedence over all other modes. If the unit initially started to operate in HEAT
mode, the other units can operate in HEAT mode only.
For example:
If the unit initially started operates under COOL (or FAN) mode, the other units can operate under any mode
except HEAT.
If one of the unit selects HEAT mode, the other operating units will stop operation and display "--" (for units
with display window only) or the auto and operation indication light will flash rapidly, the defrost indication
light will turn off, and the timer indication light will remain on (for units without a display window).
Alternatively, the defrost and alarm indication light (if applicable) will light up, or the operation indication light
will flash rapidly, and the timer indication light will turn off ( for the floor and standing type).
4.2 - MAINTENANCE
If you plan to leave the unit idle for a long time, perform the following tasks:
1. Clean the indoor unit and air filter.
2. Select FAN ONLY mode and let the indoor fan run for a time to dry the inside of the unit.
3. Disconnect the power supply and remove the battery from the remote control.
4. Check components of the outdoor unit periodically. Contact a local dealer or a customer service centre if
the unit requires servicing.
Before you clean the air conditioner, be sure to switch o the unit and disconnect the power
supply plug.
