Previous turbo fan

In the case of a conventional fan, the air outlet range was narrow

the motor side which meant the velocity of air passing through the heat exchanger was uneven.

2-stage turbo fan

A evenly spread air distr ibution across the heat exchanger is possible due to the new 2 stage turbo fan which

• Quiet operation Airflow mode can be set in 4 steps and more detailed airflow setting is possible. 21 dB only at cooling operation (22 dB at heating operation).

• MIN. HEAT Operation *Not operable from the wired remote controller that is connected individually.

The room temperature can be set to go no lower than 50 °F (10 °C), thus ensuring that the room does not get too cold when not occupied.

!

CAUTION

• When the room temperature is higher than 50 °F (10 °C), “MIN. HEAT” operation does not start. Operation starts and maintains the room temperature at 50 °F (10 °C) when the temperature drops below 50 °F (10 °C).

• When “MIN. HEAT” operation stops, the room set temperature quickly returns to the preset temperature.

• Powerful operation *Only available with Wireless RC.

20 minutes continuous operation by maximum airflow and maximum compressor speed is possible. Rapid cooling and heating makes the room comfortable quickly.

• High efficient compact design • More comfortable airflow

• Air conditioner filter features

Long-life* Ion deodorization filter

The filter deodorizes by powerfully decomposing absorbed odors using the oxidizing and reducing effects of ions generated by the ultra-fine-particle ceramic.

(*The filter can be used for approx. 3 years if it is washed under water to restore its surface action when it is dirty.)

Apple-catechin filter

Fine dust, invisible mold spores, and harmful microorganisms are absorbed onto the filter by static electricity, and further growth is inhibited and deactivated by the polyphenol extracted from apples.

• Easy maintenance Simplification of drain pan cleaning improves maintenance-ability.

 Features

 Program timer

The program timer operates the on and off timer once within a 24-hour period.

 Sleep timer

The sleep timer function automatically corrects the temperature thermostat setting according to the time setting to prevent excessive cooling and heating while sleeping.

 Simple function setting

Setting of the air conditioner selection function is performed by remote controller.

 Switching remote controller custom code

Code selector switch eliminates unit being wrongly switched. (Up to 4 codes can be set.)

* I.U.: Indoor unit

• 4 kinds of timer setup (on/off/program/sleep) are possible.

• Can be used jointly with wired remote controllers.

• Easy to change custom code (max. 4 custom codes) by button operation.

Cooling operation/Dry operation

When the sleep timer is set, the set temperature automatically rises 2 °F (1 °C) every hour. The set temperature can rise up to a maximum of 4 °F (2 °C).

Heating operation

When the sleep timer is set, the set temperature automatically drops 2 °F (1 °C) every 30 minutes. The set temperature can drop to a maximum of 8 °F (4 °C).

 Features

 High performance and compact size

 Accurate and comfortable

Indoor temperature can be detected accurately by the inclusion of a thermo sensor in the body of the wired controller.

Our system can correspond to various scenes. This wired remote controller and the optional remote sensor allows flexibility in sensor location,

and suitable for all requirements.

 Built-in timers

• Various timer setup available (on, off, and weekly).

• Equipped with weekly timer as standard function. (Start/stop function is twice per day for a week.)

• When setting up the timer, operation mode and temperature setup can be changed.

• When a failure occurs, the error code is displayed.

• Error history. (Last 16 error codes can be accessed.)

• The room temperature can be controlled by detecting the temperature accurately with built-in thermo sensor.

 Minimum heat (All) 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].

• When the room temperature is higher than 50 °F (10 °C), MIN. HEAT operation dose not start. Operation starts and maintains the room temperature at 50 °F (10 °C) when the temperature drops below 50 °F (10 °C).

• When "MIN, HEAT" operation stops, the room set temperature quickly returns to the preset temperature.

 Economy (All) 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.

• Economy operation is energy saving, as the set temperature of indoor unit is shifted by 2 °F (1 °C) and the maximum electric value of the outdoor unit is suppressed.

Example: Cooling operation

 Schedule timer

Operation setting can be changed 4 times in each day of a week, and 2 types of the schedule can be set to suit users' preference.

Example

 Prohibited settings

The remote controller operation of all indoor units comes with a lock function to prevent unapproved operations in the various rooms. The central remote controller also has a key lock function to prevent children from playing with it, etc.

CAUTION

• Be careful to avoid breaking the cable by over-tightening the binder.

• When connecting the remote controller cables, do not over-tighten the screws.

6. Attach the front case.

• Adjust the upper part of the front case first, then insert the front case until it clicks.

• When inserting the front case, do not pinch the cable.
