8 Advice for saving energy

8.1 Suitable room temperature

Set the room temperature to an appropriate value to ensure physical wellbeing, comfort and to comply with the legal standards if required. Each degree above this value significantly increases the energy consumption.

The temperature must also be suitable for the specific use being made of the room: the temperature of empty rooms and bedrooms does not have to be the same as the main living room.

8.2 Eliminating heat or cold sources

In the event that there are any heat (in cooling mode) or cold (in heating mode) sources that could be eliminated please do so (e.g. a window or a door which are not properly closed). This will ensure that the unit consumes less energy.

8.3 Operation in heating mode (heat pump)

Your unit, when operating in heating mode, acts as a heat pump, i.e. it takes heat from the outside (via the outdoor unit) and releases it inside (via the indoor unit). Nevertheless, a conventional heating system produces heat purely by consuming energy. Therefore, heating a room using a heat pump is far more economical than using conventional heating (radiators, heaters, boilers, etc.).

8.4 Ambient temperature when absent

During heating mode, an economic saving is made by keeping the room temperature at approx. 5° C lower than the normal temperature. A reduction which exceeds these 5° C does not provide any further energy savings since greater heating power is required for consecutive periods of operation in normal operating conditions.

It is only worth reducing the temperature even further in the event of prolonged absences, e.g. during holidays.

During winter when protection against freezing must be guaranteed.

8.5 Uniform heating

Often in a house only the one room is heated. In addition to the surfaces which form the perimeter of this area, i.e.

the walls, doors, windows, ceiling and floor, the adjacent rooms are cooler than the room temperature therefore: thermal energy is unintentionally lost. It is therefore difficult to adequately heat the room and an unpleasant feeling of cold is felt (the same occurs when leaving open doors which separate heated areas and unheated areas in a limited way).

This is false economy: the heating is on and, nevertheless, the ambient temperature is not pleasant. Greater comfort and a more reasonable operating mode are achieved by heating all the rooms in a house uniformly, taking into account the use being made of each room (the temperature of empty rooms and bedrooms does not have to be the same as the main room, as long as they are not significantly cooler than the main room).

8.6 Reduction in consumption during night hours (SLEEP function)

Your unit has a SLEEP function which allows the temperature to be modified automatically in relation to the predetermined values (in heating mode the temperature decreases slightly; in cooling mode the temperature increases slightly) during sleep setting period. Thus, apart from greater comfort being provided there is also a reduction in the electricity consumption. For more details regarding the SLEEP function, please consult section 7.7.1).

8.7 Reduction in consumption with programmed operating time (TIMER function)

By using the TIMER function you can adjust the operation start time of your unit. Therefore, it is possible to programme the operation of your unit to make it function only when required and thus achieve more economic operation.

8.8 Appropriate maintenance of the unit

A unit in perfect condition operates efficiently, taking maximum advantage of the energy it consumes. Ensure that your unit is correctly serviced (for more details please consult section 10). In particular, make sure that the filters are kept clean and that the air inlets and outlets are not obstructed either on the indoor or outdoor unit. Failure to do so will lead to an increase in energy consumption.

9 Troubleshooting

The table below describes a selection of problems with their possible causes and solutions, see Table 9.1.

10 Maintenance

DANGER:

Danger of electric shock.

Disconnect the unit and isolate the mains supply before proceeding to carry out maintenance on the unit. Ensure the the mains supply cannot be reconnected inadvertently. This will prevent injuries.

DANGER:

Danger of electric shock.

Do not clean the unit with water.

WARNING:

Danger of breakdowns or malfunction.

Do not use gasoline, benzine, thinner or cleansers when cleaning the unit. It may damage the coating of the unit.

WARNING:

Hot water over 40° C may cause discoloring or deformation.

10.1 Cleaning the remote controller

• Wipe the controller with a dry cloth. Do not use water to clean the remote controller.
• Do not use glass cleaners or chemical cloths.

10.2 Cleaning the indoor unit

• Wipe the outer part of the unit with a soft and dry cloth.
• For difficult stains, use a neutral detergent diluted in water. Eliminate the excess of water form the cloth before wiping. Leave the unit clean from any detergent.

10.3 Cleaning the air filters

The air filter traps the dust circulated from the room into the indoor unit.

If the filter becomes blocked, the air conditioner's efficiency will be reduced, the compressor could be damaged and the indoor unit's heat exchanger coil could freeze up.

Clean the air filter regularly to prevent this from happening. In order to do so:

- Remove the air filters by slightly pushing up the center tab until it is released from the stopper and remove the filter downwards.

• Clean the filter removing the dust or the dirt using a vacuum cleaner or cleaning them with cold water.
• Ensure that the filters are dried completely (dry in the shade) before putting them back into the unit. The activated carbon filters (where fitted) can be reactivated by placing in direct sunlight. If strange odours are still smelt replace with new. If strong odours continue to be a problem, contact your after sales service provider to fully clean the unit.
• Attach the filter correctly and make sure it is completely fixed behind the stopper. If the right and left filters are not properly fixed, this could cause a malfunction.

WARNING:

Danger of breakdowns or malfunction. Do not attach perfume systems, anti-odour systems etc. in the filter or in the inside air return. This can damage and soil the heat exchanger coil. If necessary, install these systems at the unit's outlet point and ensure they only run when the fan is on.

10.4 Cleaning the Outdoor Unit

WARNING:

Always use suitable personal protection equipment (helmet, gloves, safety boots and protective glasses).

• Wipe the outer part of the unit with a dry cloth.
• Occasionally remove dust and leaves from the inlet surface.
• Periodically clean the heat exchanger fins with a soft brush when the unit is located in a dusty environment.
• Occasionally check the base of the outdoor unit.

DANGER OF INJURY AND PHYSICAL DAMAGE!

A damaged or deteriorated base could make the unit unstable and potentially cause physical or material damage.

DANGER OF INJURY AND PHYSICAL DAMAGE!

Except for servicing or replacement, do not dismantle the outdoor unit outlet. Exposing the fan can be very dangerous.
