Unifies the air speed

1. EASY TO CLEAN ; FLOCKLESS VANE
With our original air current control mechanism, a flockless vane is
newly adapted.
The flockless vane prevents the condensation on the vane.
By changing the vane to the flockless type, the unit can be cleaned
much easier with mild household detergent.

Protruding portion A
Sending the air to the upper
area of the vane
Prevents the air comes from

2. NEW MATERIALS FOR BETTER OIL RESISTANCE
We have changed the materials of grill, filer, fan and fan casing from ABS to P.P. (polypropylene) for better oil
resistance. As a result, oil crazing is cut in half.
3. SIMPLIFIED INSTALLATION WORK (DIRECT SUSPENDING METHOD)
Simplified the installation work by changing the suspending method to the direct suspending method (suspending
the unit directly from the suspension fixture).
In this way, the unit can be attached to the suspension fixture without removing the installation parts off (Only the
side cover is removed). This method is much simpler than the “One-time installation method”.

5. EASY MAINTENANCE FILTER ; NO MAINTENANCE NECESSARY FOR 2500 HOURS
The new long-life air filter can be used continuously 2500 hours without maintenance (at general office use).

If you are using the remote controller to operate multiple indoor units, this message will appear only if the feature is not
present at every unit connected.
● When power is turned ON for the first time, it is normal that “PLEASE WAIT” is displayed on the room temperature
indication (For max. 2minutes). Please wait until this “PLEASE WAIT” indication disappear then start the operation.

temperature [ -18°F, AND the drain sensor input is at the short or open level.
(If condition 2 or 3 is still being met after the drain pump has been turned ON for 6
minutes, the drain pump is kept ON for a further 6 minutes.)

The liquid level is detected by determining whether or not the drain sensor is
submerged, based on the temperature rise after self-heating the sensor. This
process is performed if any of the following conditions is satisfied:
1 Drain pump is ON.
2 Indoor piping (liquid piping) temperature – indoor intake temperature [ -18°F
