PKFY-P06NAMU-E
PKFY-P08NAMU-E

Indoor Unit

Model Cooling capacity / Heating capacity

PKFY-P06NAMU-E 6,000 / 6,700 Btu/h
PKFY-P08NAMU-E 8,000 / 9,000 Btu/h

1. Compact Design

• Compact 11-5/8 inch (29.5cm) high body fits snugly in even limited spaces.

• Light weight 19lbs (8.5kg) unit easy to transport and install.

2. Auto-flap shutter enhances good looks

With a simple flick of the OFF switch, the air outlet can be closed off with a shutter. The shutter also functions as a flap

during operation to adjust the air flow angle, with “Auto Angle” securing a comfortable air flow.

3. Quiet operation

4. The intake grille filter can be completely removed allowing easy cleaning

PKFY-P12NGMU-E 12,000 / 13,500 Btu/h
PKFY-P15NGMU-E 15,000 / 17,000 Btu/h

1. Compact Design

Units have now been downsized to require minimal wall space.
A 20% reduction in width 39 inch (990mm) compared to previous models means that installation is possible in very narrow
spaces.

2. Auto-flap shutter enhances good looks

With a simple flick of the OFF switch, the air outlet can be closed off with a shutter. The shutter also functions as a flap
during operation to adjust the air flow angle, with “Auto Angle” securing a comfortable air flow.

3. The intake grille filter can be completely removed allowing easy cleaning
(Can be washed in water)

• Front grille
opens out

4. Quiet operation

• Airflow passage configuration that assures quiet operation

By changing fan intervals, quiet operation is achieved
without reduction in airflow. Optimal design of the
airflow passage gives a shortened fan diameter
and allows a highly compact installation.
2 Thanks to a highly practical casing configuration,
airflow generated by the fan is distributed uniformly.
3 Due to careful positioning of the vertical vane axis,
air is blown evenly from the outlet. This prevents mixing
with secondary air and also suppresses condensation.

1 The unit incorporates a random pitch cycling fan.

PKFY-P30NFMU-E 30,000 / 34,000 Btu/h

1. A further refinement of comfort with noise suppression

Remarkably low-noise operation has been achieved through the development of a “near -silent” fan and the design
which minimizes air flow resistance.

2. Auto flap shutter

With a simple flick of the OFF switch, the air outlet can be closed off with a shutter. The shutter also functions as a flap
during operation to adjust the air flow angle, with “Auto Angle” securing a comfortable air flow.

3. Easily removable filter

The presence of thumbscrews on the filters means that the filters can be quickly and smoothly removed.

Caution

Only the Power on indicator lights when the unit is stopped and power supplied to the unit.
If you press a button for a feature that is not installed in the indoor unit, the remote controller will display the “Not Available”

message.

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 disappears then start the operation.
