The most suitable air conditioner depends on the surface area, sun location, window area, presence of heat sources (lamps, appliances, number of people etc.). Take this into account! Rule of thumb, in average sunshine conditions and no presence of other heat sources: 35 BTU/h per square foot (thus 18000 BTU/h (5.1 kW) cooling capacity suits a ~515 ft2 (~50 m2) room).
Attention:
Make sure to have the professional
•The units may not be installed in places where there might be leakage of combustible gases: fire hazard.
•Make sure that an earth leakage circuit breaker is installed.
•Check whether the connection of wires between indoor and outdoor unit is not loose.
•Make sure that the air conditioner is properly earthed.
•Check the supporting structures for proper strength to carry the weight plus a safety margin.
