1. INTRODUCTION
1.1 General
The PXD split floor and ceiling units range comprise the ST (cooling only) and RC (heat
pump) models, as follows:
• Cooling Only PXD9ST PXD12ST PXD15ST
PXD18ST PXD24ST PXD30ST
• Heat Pump PXD9RC PXD12RC PXD15RC
PXD18RC PXD24RC PXD30RC
1.2 Main Features
The PXD series benefits from the most advanced technological innovations, namely :
• R410A
• Microprocessor control.
• Infrared remote control, and on unit.
• Possibility for treated air distribution to adjacent room (Accessory kit).
• High COP.
• Easy access to the interconnecting tubing and wiring connections.
• Possibility to connect a condensate pump kit with an integral over flow
protection (Accessory kit).
• Automatic treated air sweep (horizontal and vertical)
• Low indoor and outdoor noise levels.
• Easy installation and service.
1.3 Indoor Unit

1.5 Control
The microprocessor indoor controller, and an infrared remote control, supplied as
standard, provide complete operating function and programming. The unit is designed
with an on unit control board as well.
For further details please refer to the Operation Manual, Appendix A.
1.6 Outdoor Unit
The PXD outdoor units can be installed as floor or wall mounted by using a wall
supporting bracket. The metal sheets are protected by anti- corrosion paint work
allowing long life resistance. All outdoor units are pre-charged. For further information
please refer to the Product Data Sheet, Chapter 2.
It includes :
• A Rotary Compressor mounted in a soundproofed compartment.
• Axial fan.
• Outdoor coil with hydrophilic louver fins for RC units.
• Outlet air fan grill.
• Service valves” flare” type connection.
• Interconnecting wiring terminal block.
1.7 Tubing Connections
Flare type interconnecting tubing to be produced on site.
For further details please refer to the Installation Manual, Appendix A
1.8 Accessories
ASK (All Season Kit):
For low ambient working conditions in cooling, an ASK can be installed inside the
outdoor unit. This kit allows cooling operation down to outdoor temp of -10 ºC by
gradually controlling the outdoor fan speed motor.
RCW Wall Mounted Remote Control
The RCW remote control is mounted on the wall, and controls the unit either as an
infrared remote control or as a wired controller. The wired controller can control up to
10 Indoor units with the same program settings and adjustments.
For further details please refer to Optional Accessories, Chapter on this manual.
1.9 Inbox Documentation
Each unit is supplied with its own installation and operation manuals.
