1. COMPACT DESIGN
The PK series models have been downsized and now require such minimal wall space that they can even be installed
above windows. For the PK12, 11-13/16in of wall space between the ceiling and the window allows “above window”
installation. (13-3/8in for the PK24/30/36)
2. AUTO FLAP SHUTTER
With a simple flick of the OFF switch the air outlet will be closed off with a shutter. The shutter also functions as a flap
during operation to adjust the air flow angle, with “Auto Angle 1” securing a comfortable air flow.
3. INSTALLATION : FAST AND ENDLESSLY ADAPTABLE
(1) Multi-directional piping
Multi directional drain and refrigerant piping radically improves flexibility in selecting installation layouts.
PK12 drain piping can be installed in 5 directions, while PK18/24/30/36 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.

[Remote controller]
(1) Easy to Use Microprocessor
1) Ultra-Thin Remote Controller
The streamlined, wide controller is designed to
blend with any kind of interior and the adoption of
a sophisticated microprocessor allows you to
carry out a wide range of operations easily.
2) Attractive Liquid Crystal Display (LCD)
Units operation mode, set temperature, room tem-
perature, timer setting, fan speed,
and air flow direction are displayed on the
remote controller with the easily understood visual
Liquid Crystal Display (LCD).
3) Convenient 24-Hour ON-OFF Timer
The timer allows Mr.SLIM to be switched on or
(PK12/18/24/30/36FK)
PK12/18/24/30/36FK
()
PK18/24/30/36FK2
off automatically at the time is shown on the LCD.
4) Self-Diagnostic Feature Indicates Instantly
In the rare case when a problem occurs, the unit stops operating and the set temperature indicator changes to the
self-diagnostic indicator, indicating the location of the fault.
If the check switch is pressed twice, the unit stops operating and the check mode is initiated. The cause of the most
recent problem stored in the memory is displayed on the LCD. This is extremely useful for maintenance purposes.
5) Useful Memory Feature for Storing Instructions
The previous set value is memorised so that constant temperature control can be obtained. This is convenient when,
for example, a power failure occurs.
(2) Non-polar Two-Wire Remote Controller Cables
The non-polar, two-wire type remote controller cable is slim, installation is simple and trouble-free. Remote controller
wire can be extended up to 550 yards.

5. REDI-CHARGED REFRIGERANT SYSTEM
PRE-CHARGE REFRIGERANT REQUIRED FOR LINE LENGTH OF 100ft AT
SHIPMENT. PREVENTING TROUBLES DUE TO SHORTAGE OF REFRIGERANT.
The unique refrigerant circuit and a large accumulator always controls the refrigerant to its optimum condition regardless of
the length of 164ft maximum (PK12/18 130ft maximum). The additional refrigerant charging work at the field which often
caused uncertain problems heretofore is completely eliminated. This unique system serves to improve the quality of work
and reliability, and also helps
to speed up the installation work.
OC196A-4
6. HIGH RELIABILITY AND EASY SERVICING
Rear
Right
Base
Front
In addition to the self-diagnostic function, units are also equipped with a 3-minute time delay mechanism (cooling), an auto
restart function, an emergency operation function, a test run switch, etc., to assure high reliability and easy servicing.
7. FOUR-WAY PIPING ACCESS MAKES
INSTALLATION LAYOUT EASY
Piping on the outdoor unit may be connected from either of
four directions: front, rear, side or beneath the base.
This easy-access design makes it possible to install a
number of units in a compact arrangement at a single site.
The outdoor unit allows for unheard-of flexibility in
determining a piping layout, thus greatly simplifying
installation.
8. FRONT-ACCESS FACILITATES
MAINTENANCE
The outdoor unit has been designed with a front access
service panel that allows easy access to all maintenance
point, regardless of the installation layout. What’s more, this
front panel may be removed by loosening only two screws.
It all adds up to greatly simplified maintenance work.
9. NITROGEN GAS IS CHARGED TO
INDOOR UNIT
Indoor unit and refrigerant pipes are charged with nitrogen
gas (N2) instead of R-22 before shipment from the
factory.

5. OUTLET AIR SPEED AND COVERAGE RANGE
● The air coverage range is the value up to the position where the air speed is 0.8ft/sec. when air is blown out
horizontally from the unit at the High fan setting.
The coverage range should be used only as a general guideline since it varies according to the size of the
room and furniture installed inside the room.
