FEATURES
2
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.
2. LCD WIRELESS REMOTE CONTROLLER
The new wireless remote controller has a larger easy-to-read temperature display, and executes ON/OFF commands
and temperature settings with a press of the button.
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 1” securing a comfortable air flow.
4. INSTALLATION : FAST AND EASILY ADAPTABLE
(1) Multi-directional piping
Multi directional drain and refrigerant piping radically improves flexibility in selecting installation layouts.
PK18/24/30/36FL3 models boast refrigerant piping in 4 directions and drain piping in 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 and convenient wireless remote controller
The presence of thumb screws on the filters means that the filters can be quickly and smoothly removed.
5. HIGH RELIABILITY AND EASY SERVICING
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.
6. NITROGEN GAS IS CHARGED TO INDOOR UNIT
Indoor unit and refrigerant pipes are charged with nitrogen gas (N2) instead of R22 before shipment from the factory.
