1. INTRODUCTION

1.1 General

The new DCI 72Z, DCI 80Z split unit range comprises the following RC (heat pump)

models:

• CKD 025

• CKD 030

1.2 Main Features

The DCI CKD series benefits from the most advanced technological innovations, namely:

DC inverter technolegy

R410a

High COP

Pre-Charged units up to the max’ allowing tubing distance

Networking system connectivity

A dry contract for presence detector or power shedding functions(configurable)

Cooling operation at outdoor temprature down to -10°C

Heating operation at outdoor temprature down to -15°C

Bended indoor coil with treated aluminum fins and coating for improved efficiency

Easy access to the interconnecting tubing and wiring connections

Automatic treated air sweep.

Low indoor and outdoor noise levels.

Easy installation and service.

1.3 Indoor Unit

The indoor unit is ceiling mounted, and can be easily fitted to residential and commercial applications

It includes:

A large diameter centrifugal fan, allowing low noise level operation

Motorized flaps

Bended indoor coil with hydrophilic aluminum fins.

Advanced electronic control boc assembly.

1.4 Control

The micro processor indoor controller, and an infrared remote control, supplied as standard,

provides complete operating function and programming.

For further details, please refer to the Operation/Instullation Manual.

1.5 Outdoor Unit

DCI outdoor units can be installed as floor 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,
