Air Conditioner Service Manual

 

15

 

  The air conditioner must be installed by professional or qualified persons. Do not install the appliance 

at a  distance of less than 50 cm from inflammable substances (alcohol, etc.) Or from pressurized 

containers  (e.g. spray cans). 

  If the appliance is used in areas without the possibility of ventilation, precautions must be taken to 

prevent  any leaks of refrigerant gas from remaining in the environment and creating a danger of fire. 

  The packaging materials are recyclable and should be disposed of in the separate waste bins .Take 

the  air conditioner at the end of its useful life to a special waste collection center for disposal. 

 

Only use the air conditioner as instructed in this booklet. These instructions are not intended to cover 

every possible condition and situation. As with any electrical household appliance, common sense and 

caution are therefore always recommended for installation, operation and maintenance.

 

  The appliance must be installed in accordance with applicable national regulations. 

  Before accessing the terminals, all the power circuits must be disconnected from the power supply. 

  The appliance shall be installed in accordance with national wiring regulations. 

 

This appliance can be used by children aged from 8 years and above and persons with reduced physical, 

sensory or mental capabilities or lack of experience and knowledge if they have been given supervision 

or  instruction  concerning  use  of  the  appliance  in  a  safe  way  and  understand  the  hazards  involved. 

Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children 

without supervision.

 

5.2 SAFETY RULES AND RECOMMENDATIONS FOR THE USER

 

  Do not try to install the conditioner alone; always contact specialized technical personnel. Cleaning 

and  maintenance must be carried out by specialized technical personnel. In any case disconnect 

the  appliance from the mains electricity supply before carrying out any cleaning or maintenance. 

  Ensure that the mains voltage corresponds to that stamped on the rating plate. Keep the switch or 

power  plug clean. Insert the power plug correctly and firmly into the socket, thereby avoiding the risk 

of electric  shock or fire due to insufficient contact. 

  Do not pull out the plug to switch off the appliance when it is in operation, since this could create a 

spark  and cause a fire, etc. 

  This appliance has been made for air conditioning domestic environments and must not be used for 

any  other purpose, such as for drying clothes, cooling food, etc. 

  The packaging materials are recyclable and should be disposed of in the separate waste bins. Take 

the  air conditioner at the end of its useful life to a special waste collection center for disposal. 

  Always use the appliance with the air filter mounted. The use of the conditioner without air filter 

could  cause an excessive accumulation of dust or waste on the inner parts of the device with 

possible  subsequent failures. 

  The user is responsible for having the appliance installed by a qualified technician, who must check 

that it  is earthed in accordance with current legislation and insert a thermomagnetic circuit breaker. 

  The batteries in remote controller must be recycled or disposed of properly. Disposal of Scrap Batteries 

--- Please discard the batteries as sorted municipal waste at the accessible collection point. 

  Never remain directly exposed to the flow of cold air for a long time. The direct and prolonged exposition
