The
38HB/HF
cooling units and heat pumps are units which feature a
split-system construction with components optimised for the R-410A
refrigerant.
They are presented in two different elements:
- An outdoor unit (38HB/HF series) which features a horizontal
construction and is equipped with a centrifugal fan, a hermetic
scroll-type compressor and an electric panel with electronic control.
Supply and return air on the same side.
- An indoor unit or or air-conditioning unit (40HB/HF series) which
features a horizontal construction and has supply and return air on
the same side.
• 38HB/HF series
38HB series:
Outdoor unit
cooling-only
air-condensed with
centrifugal fan, horizontal design, designed for installation indoors.
38HF series:

air-air reversible with
centrifugal fan and expansion valve, horizontal construction,
designed for indoor installation.
•
40HB/HF
series
40HB series:
Indoor unit
cooling only
with centrifugal fan and
expansion valve, horizontal construction, designed for installation
on premises connected to a network of ducts.
40HF series:
Indoor unit
heat pump
reversible with centrifugal fan
and expansion valve, horizontal construction, designed for installation
on premises connected to a network of ducts.
The units comply with standards: EN 60-204 - EN 378-2, and directives:
Machinery 2006/42/EC - EMC 2004/108/EC - LVD 2006/95/EC - PED
2014/68/EC (Category 2).
Those in charge of the installation, commissioning, operation and
maintenance of the unit must know the instructions contained in this
brochure and the speci
fi
c technical characteristics of the installation
place.
With a condensation pressure control operating down to -10ºC.
When the outdoor temperature is usually below 5ºC WB it is recommended
installing a support element.
