Chillers and heat pumps for outdoor condensed
in the air with R410A Series NRL have been de-
signed and manufactured to satisfy heating and
cooling needs and the production of domestic
hot water (DHW) in medium to small commercial
or residential buildings.
Maximum reliability
The presence of several scroll compressors allows
NRL chillers various partialisations of the cooling
capacity.
Models:
1. NRL "°" standard chiller
2. NRL "H" heat pump *
3. NRL "C" motocondensing
The versions can be in different set-ups at the
same time in order to satisfy a wide range of
plant engineering solutions:
1. "A" HIGH EFFICIENCY
2. "E" SILENCED HIGH EFFICIENCY
3. "D" WITH DESUPERHEATER
4. "T" WITH TOTAL RECOVERY

4. SELECTION AND PLACE OF
INSTALLATION
Before beginning installation consent with
client and pay attention to the following
recommendations:
The support surface must be capable of
supporting the unit weight.
The safety differences between the
unit and other appliances or structures
must be scrupulously respected so that
the inlet and outlet air from the fans is
free to circulate.
The unit must be installed by an
enabled technician in compliance with
the national legislation in force in the
country of destination, respecting the
minimum technical spaces in order to
allow maintenance.
5. POSITIONING
The machine is delivered from the factory
wrapped in estincoil.
Before handling the unit, verify the lifting
capacity of the machines used.
After removal of packaging, movement of
apparatus must be carried
out by qualified and adequately equipped
personnel. To handle the machine: see
