INTRODUCTION

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

● DC inverter technology.

● 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 and Active Electrostatic 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.

SM WNGDCI 2-E.4 GB

● 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.
