●Location that is subjected to strong high frequencies raditation.
●Location that is subjected to potential lightening srtike.
●Location at altitude of 3000m or higher (except during product storage and transport).
Refer to below for details.

tipping over. Improper installation may cause water leakage, tipping,
damage of the product or injure the operator.
Keep the ambient temperature of the product between 2 to 45oC.
Operation out of this ambient temperature range may cause a
malfunction of the product. Operating the product in an environment
temperature of 45 oC may reduce the heat discharging efficiency of
the heat exchanger and the safety device may function, resulting in
the product operation stoppage.
The installer/end user is responsible for carrying
