If refrigerant density exceeds the limit, consult the dealer and install the ventilation system.
Otherwise lack of oxygen can occur resulting in serious accident.
• Install the unit in a location where unit will remain stable, horizontal and free
of any vibration transmission.
Unsuitable installation location can cause the unit to fall resulting in material damage and personal injury.
