1. INTRODUCTION
1.1 General
The new Alpha split wall mounted is based on the compact range. It comprise the ST
(cooling only) and RC (heat pump) models, as follows:
● Cooling Only Alpha 7 ST/CON 7 ST; Alpha 9 ST/GCN 9 ST;
Alpha 12 ST/GCN 12 ST; Alpha 17 ST/ONG 17 ST;
● Heat Pump Alpha 7 RC/CON 7 RC; Alpha 9 RC/GCN 9 RC;
Alpha 12 RC/GCN 12 RC; Alpha 17 RC/ONG 17 RC;
The indoor Alpha units are available as LED display types, featuring esthetic design,
compact dimensions, and low noise operation.
1.2 Main Features
The Alpha series benefits from the most advanced technological innovations, namely:
● R410A models
● Microprocessor control.
● Infrared remote control with liquid crystal display.
● Indoor large diameter cross flow fan, allowing low noise level operation.
● Bended indoor coil with treated aluminum fins and coating for improved
efficiency.
● High COP.
● Easy access to the interconnecting tubing and wiring connections, so that
removing the front grill or casing is not necessary.
● Refrigerant pipes can be connected to the indoor unit from 5 different optional
directions.
● Automatic treated air sweep.
● Easy installation and service.
● 4M length tubing connection kit is provided in the outdoor unit (optional).

1.7 Tubing Connections
Flare type interconnecting tubing can be produced on site.
A connection pipe kit is provided in outdoor package.
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.
1.9 Inbox Documentation
Each unit is supplied with its own installation and operation manuals.
