• Do not touch the switches with sharp objects. Doing so will cause injury, trouble, or electric shock.

• Do not insert articles into the slit parts of this unit. Doing so will cause trouble, heating, or electric shock.

1-2. Features and functions

This mark indicates procedures

WARNING

which, if improperly performed, might lead to the death or serious injury of the user.

• In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the electrical breaker, and consult authorized service personnel.

• Do not repair or modify any damaged cable by your self. Let the authorized service personnel to do it. Improper work will cause an electric shock or a re.

• This unit contains no user-serviceable parts. Always consult authorized service personnel for repairs.

• When moving, consult authorized service personnel for disconnection and installation of this unit.

• Do not touch with wet hands. It may cause an electric shock.

• If children may approach the unit, take preventive measures so that they cannot reach the unit.

• Do not repair or modify by yourself. It may cause a fault or accident.

• Do not use ammable gases near the unit. It may cause a re from leaking gas.

This mark indicates procedures which,

CAUTION

if improperly performed, might possibly result in personal harm to the user or damage to property.

• Do not set vessels containing a liquid on this unit. Doing so will cause heating, re or electric shock.

• Do not expose this unit directly to water. Doing so will cause trouble, electric shock or heating.

• Dispose of the packing materials safely. Tear and dispose of the plastic packing bags so that children cannot play with them. There is the danger of suffocation if children play with the original plastic bags.

• Do not place electrical devices within 1 m (3.3 ft) of this unit. It may cause malfunction or failure.

MINIMUM HEAT OPERATION

To avoid too much decrease of temperature in the room, it is operated to prevent the room temperature dropping below 50°. When normal operation starts, the minimum heat operation stops.

ECONOMY OPERATION

Operation of the indoor units in economy mode, which saves a little power, reduces energy use more than normal operation. If the room is not cooled (or heated) well during economy operation, select normal operation.

ALL MINIMUM HEAT OPERATION

While this function is selected, all indoor units start the minimum heat operation when all the indoor units are stopped by operation of the [On/Off button] on the Central remote controller.

ALL ECONOMY OPERATION

If all the indoor and outdoor units are changed to economy mode, this can save more energy than setting of each indoor unit individually.

OUTDOOR UNIT LOW NOISE OPERATION

The outdoor units are operated to reduce noise during the preset hours, such as at night.

SCHEDULE TIMER OPERATION

Operating automatically in accordance with the preset weekly schedule. Different schedule can be set for each indoor unit.

REMOTE CONTROLLER PROHIBIT
