1. INTRODUCTION

1.1 General

The new KXL DCI split cassette range comprise the following RC(heat pump) models:

•KXL 24 DCI

•KXL 30 DCI

The New DCI KN units can be easily fitted to residential and commercial applications

featuring esthetic design, compact dimensions, and low noise operation.

1.2 Main Features

The DCI KN series benefits from the most advanced technological innovations,

namely:

•DC inverter technolegy

•R410a

•High COP

•Lego Concept

•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

•Supports Indoor Air Quality features, such as – Ionizer, Active Electro-Static

Filter

•Indoor large diameter cross flow fan, allowing low noise level operation

•Bended indoor coil with treated aluminum fins and coating for improved

efficiency

•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 6 different optional

directions

•Water condensate tray is equipped with two optional drain connections

•Automatic treated air sweep.

•Low indoor and outdoor noise levels.

•Easy installation and service.

1.3 Control

The microprocessor indoor controller, and an infrared remote control, supplied as

standard, provide complete operating function and programming.

Remote controlers:RC-3/4,µBMS

Networking system Airconet version 4.2 and up MIU SW version H8 and up.
