When installing the unit

Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.
Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified may result in fire or electric shock.
Do not cut, kink, or otherwise damage nor modify the power supply cord. In addition, avoid using the power cord in close proximity to heaters, and never place heavy objects — including the unit itself — on the power cord, as doing so may result in fire or electric shock.
The terminals marked with the symbol are hazardous live. The external wiring to these terminal requires installation by an instructed person.

All units

Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling down and causing personal injury and /or property damage.
Install the unit only in a location that can structurally support the weight of the unit and the mounting bracket. Doing otherwise may result in the unit falling down and causing personal injury and/or property damage.
Owing to the unit’s size and weight, be sure that at least two persons are available to install the unit. Failure to do so could result in personal injury.
Tighten each nut and bolt securely. Ensure that the bracket has no loose joints after installation to prevent accidents that could result in personal injury.

When the unit is in use

To prevent a fire or electric shock, never open nor remove the unit case as there are high-voltage components inside the unit. Refer all servicing to qualified service personnel.
Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they accidentally spill into the unit, this may cause a fire or electric shock.
Do not insert nor drop metallic objects or flammable materials in the ventilation slots of the unit’s cover, as this may result in fire or electric shock.
Do not touch a plug during thunder and lightning, as this may result in electric shock.
Class I construction shall be connected to a main socket outlet with a protective earthing connection.

WARNING

When installing the unit

Should the following irregularity be found during use, immediately switch off the power, disconnect the power supply plug from the AC outlet and contact your nearest TOA dealer. Make no further attempt to operate the unit in this condition as this may cause fire or electric shock.
If you detect smoke or a strange smell coming from the unit.
If water or any metallic object gets into the unit
If the unit falls, or the unit case breaks
If the power supply cord is damaged (exposure of the core, disconnection, etc.).

CAUTION

When Installing the Unit

Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric shock.
When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord itself. Operating the unit with a damaged power supply cord may cause a fire or electric shock.
When installing the equipment, please hold space around the power plug for easy access.
The power plug is used as a disconnection device and must be easily accessible. Make sure that the power cord is not stepped on or compressed, particularly near the power plug, power socket, and at the point where it exits the device.
When moving the unit, be sure to remove its power supply cord from the wall outlet. Moving the unit with the power cord connected to the outlet may cause damage to the power cord, resulting in fire or electric shock. When removing the power cord, be sure to hold its plug to pull.
Do not block the ventilation slots in the unit’s cover. Doing so may cause heat to build up inside the unit and result in fire. Also, periodically clean the ventilation slots of dust.
Avoid installing the unit in humid or dusty locations, in locations exposed to direct sunlight, near the heaters, or in locations generating sooty smoke or steam as doing otherwise may result in fire or electric shock.
When unpacking or moving the unit, be sure to handle it with two or more persons. Falling or dropping the unit may cause personal injury and/or property damage.

When the Unit is in Use

Do not place heavy objects on the unit as this may cause it to fall or break which may result in personal injury and/or property damage. In addition, the object itself may fall off and cause injury and/or damage.
