1.2 INSTALLATION
1.2.1 HEAT DISSIPATION
If the heat dissipation vent behind this unit is blocked, cooling
efficiency may deteriorate and temperature inside the unit will
rise. The temperature sensor that protects the unit will be
activated when internal temperature exceeds the predetermined
level and power will be turned off automatically.
Therefore, please make sure pay attention not to block the heat
dissipation vent as well as the ventilation outlet behind the unit
and ensure that there is room for ventilation around it.
Do not put foreign objects near the ventilation holes as this
can result in fire or electrical hazards.
Do not block the ventilation holes as this may cause the
internal temperature to rise and possibly result fire.
