WARNING
• Install the air conditioner in a location which can withstand a load do at least 5
times the weight of the main unit and which will not amplify sound or vibration. If the
installation location is not strong enough, the indoor unit may fall and cause injuries.
• If the job is done with the panel frame only, there is a risk that the unit will come
loose. Please take care.
