IAQ Plasma Filter
High performance electronic air cleaner removes dust and odor, improving indoor
air quality.

Low Ambient
Systems can operate in cooling mode even when outdoor ambient is 0F, 14F or 32F, depending on model, without modification.

Cold Prevention
Indoor coil will warm prior to fan operating, preventing cold air during heating mode.

Slender Fit
Cassette body can be moved downward into the room
1-3/8" to accommodate limited ceiling space.

Apple Catechin Filter
Dust, mold spores and microorganisms are absorbed onto the filter by static electricity and growth is inhibited and deactivated by the polyphenol ingredient extracted from apples.

Ion Deodorizing Filter
The filter deodorizes by powerfully decomposing absorbed odors using the oxidizing and reducing effects of ions
generated by the ultrafine particle ceramic.

Coil Dry Mode

After power is off, an internal drying function starts preventing the growth of mold and bacteria inside the indoor unit.

Wired/Wireless Switching
This switch must be enabled when installing the optional wired remote controller

Remote Controller Sensor
Room temperature sensor is located in optional wired remote controller only.

Pump Down Operation
Collects all refrigerant in the system back into the outdoor unit when the unit is to be moved or before servicing the refrigerant circuit.

High Ceiling Mode
Temperature at the top of a high ceiling room may be warmer then the space occupied; this mode allows system to adjust for this difference.

Branch Duct Capable
Systems are capable of attaching two field-supplied 4" branch ducts providing 50% of the cooling up to 16 feet away.

Fresh Air Intake
Outside air can be introduced by attaching field supplied flexible duct to fresh air knockouts.
