INTRODUCTION 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 : 1.3 • R410A • Microprocessor control. • Infrared remote control, and on unit.
INTRODUCTION 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.
