2FEATURES
2-1. New 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.
2-2. 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.
2-3. Front power supply box for easier wiring even after installation
The front power supply box allows electrical wiring work to be done after the indoor unit has been installed. For easier
installation, all the screws required for securing the indoor unit to the wall are accessible from the front of the unit.
2-4. 4-way piping provides more flexibility in selecting installation sites
All piping including drainage can be connected from the rear, right, base, and left of the unit, providing much greater
flexibility out piping and selecting installation site.

2-1. New Compact Design
Units have now been downsized to require minimal wall space.
A20% reduction in width 38-31/32 inch (990mm) compared to previous models means that installation is possible in very nar-
row spaces.
2-2. Auto-flap shutter Enhances Good Looks
With a simple flick of the OFF switch the air outlet can be closed off with a 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.
2-3. The Intake Grille Filter Can be Completely Removed Allowing Easy Cleaning
(Can be washed in water)
• Front grille
opens out
2-4. Quiet Operation
•Airflow passage configuration that assures quiet operation
1The unit incorporates a randompitch cycling fan.
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.
2Thanks to a highly practical casing configuration,
airflow generated by the fan is distributed uniformly.
3Due 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.
2-5. 4-way Piping Provides more Flexibility in Selecting Installation Sites

OC292-6
2-1. COMPACT DESIGN
The PKFY series models have been downsized and now require such minimal wall space that they can even be
installed above windows. For the PKFY series models, 14-9/16 inch (37 cm) of wall space between the ceiling and the
window allows “above window” installation.
2-2. A FURTHER REFINEMENT OF COMFORT WITH NISE SUPPRESSION
Remarkably tow-noise operation has been achieved through the development of a “near -silent” fan and the design
which minimises air flow resistance.
2-3. 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.
2-4. INSTALLATION : FAST AND ENDLESSLY ADAPTABLE
(1) Multi-directional piping
Multi directional drain and refrigerant piping radically improves flexibility in selecting installation layouts.
PKFY- • NFMU-A models boast refrigerant piping in 4 directions and drain piping 2 directions.
(2) Back plate installation guide
The back plate installation guide gives clear instructions on installation positions. The enlarged back plate secures the
unit firmly to the wall, while the support piece which lifts the unit makes left side piping work much easier.
(3) Easily removable filter
The presence of thumbscrews on the filters means that the filters can be quickly and smoothly removed.
