2 Features
2.1.
Cassette Type features
2.1.1.
Three Airflow Patterns for Extra Comfort
• Multi-comfort air control.
2.1.2.
Low Noise and High Air Flow Rate
• The cassette indoor unit is equipped with newly-develop turbo fan; the new shape produces low noise and high air flow rate.
2.1.3.
Fast, Flexible Installation
• Drain hose can be elevated 750 mm from the base of the unit simply by connecting an elbow. This adds to ease of drain piping
work, and flexibility in locating the indoor unit.
It automatically adjusts the fan speed according to the indoor temperature.

Outdoor Unit
2.2.1.
Flexible Installation in Smaller Spaces (for 34, 43, 50DBE only)
• Spacing-saving outdoor unit with the improvement of the outdoor unit fan makes it possible to install the outdoor unit into a
smaller space where the conventional model cannot be installed.

• Long Pipe design with maximum piping length of 30m (S-F18DB4E5 / U-B18DBE5 only) and 50m.
• Flexible 4-way piping.
• Flexible 4-way piping.
• Centralized Drain Method gathered multiple outdoor unit’s drain pipes into a single drain pipe to make installation easier and
also improve appearance.
• Side-by-Side Continuous Installation is possible even outdoor units with different capacities.
2.2.2.
Quiet, Efficient Design
• A host of silencing technologies achieves super-quiet operation.
• The Noise-Suppressing Winglet Fan is a result of new research into vane design theory. The unique curved shaped suppressed
• The Noise-Suppressing Winglet Fan is a result of new research into vane design theory. The unique curved shaped suppressed
the generation of vortexes, thus reduces air flows noise.
• Operating efficiency is improved and energy consumption reduced.
2.2.3.
Low Ambient Cooling Operation
• The unit can set for cooling even when the outdoor temperature drops to -10
qC. This is ideal for location such as non-residential
computer room (where the temperature is not less than 21
qC and humidity is not more than 45%) that require cooling even in
winter.

Wired Remote Control
1. The new design includes an easily-visible red pilot lamp. The power can be turned on and off at a single touch, without open-
ing the cover.
2. Has a build-in thermistor, allowing indoor temperature detection in accordance with indoor conditions by switching with main
unit thermistor.
3. Twin non-polar wires make installation work easy. (10 m cable supplied as accessory.)
2.4.
Wireless Remote Control
1. New design with compact size. (Operation range within approximately 8 m.)
2. Built-in timer with OFF/ON timer setting (within 24 hours)
