1. GENERAL INFORMATION E-1 PRECAUTIONS Installing and servicing of air conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should install or service this equipment. Untrained personnel can perform basic maintenance function such as cleaning coil and filters. Trained service personnel should perform all other operations. When working on air conditioning equipment, observe precautions in the literature, tags and labels attached to the unit. WARNINGS The operating voltge of electrical power supply should be within the voltage mentioned on unit nameplate data. The capacity of electrical kwh counter should be larger than the operating currents required for air conditioner(s) and any other electrical domestic appliances in use simultaneously from the same supply. The installation of electrical distribution box after the electrical KWH counter is necessary to properly distribute the electrical loads. The electrical distribution box should be equipped with circuit breakers according to the electrical loads. For each installed air conditioner, a separate circuit breaker with its own overload should be installed on the electrical distribution box. The installation of two-pole automatic circuit breaker is necessary to operate the air conditioner. The circuit breaker must be installed to be far away from any flammable materials (curtains etc.). The circuit breaker must be suitable for air conditioner. Disconnect the electrical mains supply prior to any maintenance operations or prior to handling any internal unit parts. The manufacturer declines any liability for damage resulting from modifications or errors in the electrical or refrigerant connections, made during the installation, or from the improper use of this equipment. This will void the unit warranty immediately. Failure to observe electrical safety codes may cause a fire hazard in case of short circuits. This system will only work safely and correctly, if installed and tested by qualified personnel. Do not open the electronic remote controller to avoid possible damage. In case of malfunction contact a qualified service engineer. The unit contains rotating equipment (fan). Ensure that this is out of reach for children. Be conscious of the room temperature and general comfort, particularly when this is used near children, senior or handicapped people. For correct use, the air conditioner must operate within the temperature limits indicated in the table Operating Limits included in the installation manual. Incorrect use of the system outside these limits may cause malfunction and dripping water. Controller batteries contain polluting elements. When exhausted, they must be disposed of in accordance with local requirements. Do not switch off the split system by disconnecting the electric power supply. The system must always be switched off using the remote control.

6. CONSIDERATIONS FOR OPTIONAL WIRELESS REMOTE CONTROL E-7 WHEN DIRECTING THE TRANSMITTER OF WIRELESS REMOTE CONTROL TO THE RECEIVER OF INDOOR UNIT FROM A CERTAIN LOCATION, CHECK THE FOLLOWING POINTS: 1- Avoid direct sunlight on the receiver of indoor unit, which may interfere with good signal reception 2- No obstructions such as curtains or plants should be between the remote control and the receiver of room controller. 3- The maximum operating range for the remote control is approximately 5 meters. 4- The remote control must be directed toward the receiver of room controller when pressing the buttons of the desired functions. An acoustical acknowledgement sound (beep) will indicate that signal has been received. HOW TO INSERT BATTERIES: (a) Remove the cover of battery compartment at the back of the remote control by pressing the tab toward inside, in the direction of the arrow. (b) Mount the two-battery size AAA 1.5 Volt supplied with the remote control. Then close the cover of the battery component. Note: During mounting of batteries check battery symbols (+, -) indicated in batteries compartment. NOTES: 1. The remote control uses two alkaline batteries (2 X 1.5 Volt). 2. Do not use used batteries or batteries of different types, as this may cause the air conditioner to malfunction. 3. Batteries should only be changed after turning OFF the air conditioner. 4. The average battery life during normal use is approximately one year. 5. Batteries must be removed from the remote control before they are thrown away. 6. Batteries must be thrown away in safer way.
7. AIR FILTER CLEANING E-8 - The air filters supplied with the unit are high-efficiency washable and recyclable filters. - To establish, how frequently these should be cleaned, the operating conditions must be taken in to account. - CLEANING OF ACRYLIC-FIBRE STANDARD FILTERS: First clean the filter with a vacuum cleaner Rinse filter under running water, and dry it every month. Notes: (1) After cleaning, put the filters back in the correct positions. (2) Before operating the air conditioner, check that air filters are in their places inside unit. 8. PERIODICAL CHECKS For a good operation of the air conditioner it is recommended to carry out checks and maintenance as indicated. Recommended maintenance intervals may very depending on the installation environment, e.g. dusty zones, etc. Indoor Unit Every Month Every 4 Months Every Year Clean air filter (1) Clean drain pipe (2) Change controller batteries Outdoor Unit Every Month Every 4 Months Every Year Clean outdoor coil from outside (2) Clean outdoor coil from inside Blow air over electric parts (2) Check electric connection tightening (2) Clean fan wheel (2) Check fan tightening (2) Clean drain pan (2) (1) Increase frequency in dusty zones. (2) Operations to be carried out by qualified service personnel.
