1. INTRODUCTION

CONTENT

1.1 General

The new Alpha / Delta split wall mounted is based on the compact range. It comprise
the ST (cooling only) and RC (heat pump) models,

The indoor Alpha / Delta units are available as LED display types, featuring esthetic

design, compact dimensions, and low noise operation.

1.2 Main Features

The Alpha / Deltaseries benefi ts from the most advanced technological innovations,
namely:

● R410A models

● Microprocessor control.

● Infrared remote control with liquid crystal display.

● Indoor large diameter cross fl ow fan, allowing low noise level operation.

INTRODUCTION

● Bended indoor coil with treated aluminum fi ns and coating for improved

effi ciency.

● 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).

1.3 Indoor Unit

The indoor unit is wall mounted, and can be easily fi tted to many types of residential
and commercials applications.

It includes:

● Casing with air inlet and outlet grills.

● A large-diameter tangential fan.

SM ALPHA 1-E.3 GB

● Bended coil with treated aluminum fi ns.

● Motorized fl aps

● Multi-speed motor with internal protection

● Advanced electronic control box assembly

● Interconnecting wiring terminal block

● Mounting plate

1.4 Filtration

The Alpha / Delta series presents several types of air fi lters

● Easily accessible, and re-usable pre-fi lters (mesh)

● Pre-charged electrostatic fi lter (optional)

● Active carbon fi lter (optional)

1.5 Control

The microprocessor indoor controller, and an infrared remote control, supplied as
standard, provide complete operating function and programming. For further details
please refer to the Operation Manual, Appendix A.

1.6 Outdoor Unit

The Alpha / Delta outdoor units can be installed as fl oor or wall mounted units 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 fi ns for RC units.

● Outlet air fan grill.

● Service valves” fl are” type connection.

● Interconnecting wiring terminal block.

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
