INTRODUCTION 1. INTRODUCTION 1.1 General The new DNG ducted split unit range comprises the ST (cooling only) as well as RC (heat pump) models, it is available at 1PH, 3PH as follow: âą 1PH => DNG 18, 24, 30, 37, 42 âą 3PH => DNG 18, 24, 30, 37, 47 Remote control compatibility âą The DNG unit is compatible with remote controls RC3, RC4, RCW1, RCW2 1.2 Main Features The DNG series beneïŹts from the most advanced technological innovations, namely: âą R410A refrigerant for all the range.
INTRODUCTION 1.3 Indoor Unit The indoor unit can ïŹt easily to many types of residential and commercials applications. It includes: âą High technology plastic fan and fan housing. âą A drain pool that is under the entire unit with internal downward slope. âą An over-ïŹow switch that stops compressor operation in case drainage tube is blocked. âą A bended coil with treated aluminium ïŹns. âą 3-speed fan motor with internal protection with extra speed for higher external static pressure.
INTRODUCTION 1.7 Outdoor Unit The DNG outdoor units can be installed as ïŹoor or wall mounted units by using a wallsupporting 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.
