gas will be produced.
• Install a circuit breaker that meets the specifications in the installation manual and the stipulations in the local
regulations and laws.
• Do not wash the Air to Air Heat Exchanger with DX Coil Unit. Doing so may result in electric shock.
• When the Air to Air Heat Exchanger with DX Coil Unit is operated with a combustion appliance in the same place, be
careful of ventilation to let fresh air enter the room. Poor ventilation causes oxygen shortage.
• Be sure to stop running the air conditioner and turn off the breaker before cleaning.
Otherwise, injury may result as the fan is rotating at high speed inside the unit.
