1 - INTRODUCTION
The 50EN/EH range consist of autonomous and compact air-air
units of horizontal design, rooftop type.
They include inside all the components required for providing
the proper air conditioning to the installation.
● 50EN series: Units for cooling operation.
● 50EH series: Units for reversible heat pump operation.
The range of capacities of these units allows the air conditioning
of medium and large surface areas used for business or industry.
The unit is connected directly to an air distribution ductwork
without additional elements or equipment, pipes, cables, etc.
taking no fl oor space at all. This design reduces the cost of
installation, facilitates a quick connection and ensures reliable
operation.
After manufacturing, all units are charged with refrigerant
and are tested at the factory, verifying the correct operation
of all their components within the operating range for which
they are intended.
The units comply with European Directives:
● Machinery Directive 2006/42/EC (MD)
● Electromagnetic Compatibility Directive 2014/30/EU (EMC)
● Low Voltage Directive 2014/35/EU (LVD)
● Pressure Equipment Directive 2014/68/EU (Category 2) (PED)
● RoHS Directive 2011/65/EU (RoHS)
● Eco-design Directive 2009/125/EC (ECO-DESIGN)
● Energy Labelling Directive 2017/1369/EU (ECO-LABELLING)
● Harmonised Standard: EN 378-2:2012 (Refrigerating systems
and heat pumps - Safety and environmental requirements).
Technicians who install, commission, operate and service the
unit must possess the necessary training and certifi cations,
understand the instructions given in this manual and be familiar
with the specifi c technical characteristics of the installation site.
