1. INTRODUCTION

1.1 General

The new WNG DCI INVENTER split wall mounted range has expanded, comprising
two additional RC(heat pump) models:

● WNG50

● WNG60

● WNG80

The indoor WNG units are available as LED or LCD display types, featuring esthetic
design, compact dimensions, and low noise operation.

1.2 Main Features

The WNG DCI 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 contact for clock or power shedding functions (configurable).

● Base heater connection.

● Cooling operation at outdoor temperature down to -10°C.

● Heating operation at outdoor temperature 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 5 different

optional directions.

● Automatic treated air sweep.

● Low indoor and outdoor noise levels.

● Easy installation and service.
