NTRODUCTION
The 50HF/HB heat pumps and cooling unit are packages air to air
units, of horizontal compact construction, made for operation indoors.
They are equipped with centrifugal fans, air coils, scroll compressor
and electronic control with microprocessor, optimized components for
the R-410A refrigerant.
Are appropriate for air conditioning applications in medium power in
offi ces, commercial and industrial spaces where the facade aesthetics
must be preserved.
• 50HF Series: Air to air cooling autonomous units.
• 50HB Series: Reversible air to air heat pump autonomous units.
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 2006/42/EC -
EMC 2014/30/EU - LVD 2014/35/EU - PED 2014/68/EC (Category 2)
- RoHS 2011/65/EU - Eco-design 2009/125/CE - Eco-labelling 2010/30/
EU; and with Harmonised Standard: EN 378-2:2012.
Those in charge of the installation, commissioning, operation and
maintenance of the unit must know the instructions contained in this
brochure and the specifi c technical characteristics of the installation site.
