refrigerantgas(r410a)
This unit contains fluorinated greenhou-
se gases covered by the Kyoto Protocol.
Maintenance and disposal operations
must be only carried out by qualified
staff, in compliance with existing laws.
DANGER!
The refrigerant circuit is under pressure.
Moreover, very high temperatures an be
reached. The appliance may only be pe-
ned by an SAT service technician or by a
qualified technician.
Work on the cooling circuit may only be
carried out by a qualified refrigeration
technician.
R410A REFRIGERANT GAS
The cooler comes supplied with a
ufficient quantity of R410A refrigerant
gas. This refrigerant is chlorine-free
and does not damage the ozone layer.
R410A is not flammable. However,
all maintenance operations must be
carried out exclusively by a specialised
technician using suitable protective
equipment
DANGER OF ELECTRICAL DISCHARGE!
Before opening the heat pump, comple-
tely disconnect the appliance from the
power mains.

1.2. WARNINGS REGARDING SAFETY AND
INSTALLATION STANDARDS
1. The chiller must be installed by a qualified and
suitably trained technician, in compliance with
the national legislation in force in the country of
destination.
AERMEC will not assume any responsibility for
damage due to failure to follow these instruc-
tions.
2. Before beginning any operation, READ THESE
INSTRUCTIONS CAREFULLY AND CARRY OUT THE
SAFETY CHECKS TO REDUCE ALL RISK OF DANGER
TO A MINIMUM. All the staff involved must have
thorough knowledge of the operations and any
dangers that may arise at the moment in which
the installation operations are carried out.

NRL FC 2000-3600 60Hz
EN
2. SELECTION AND PLACE OF INSTALLATION
Before beginning installation consent with client and pay atten-
tion to the following recommendations:
1. The support surface must be capable of supporting the
unit weight;
2. The safety differences between the unit and ther applian-
ces or structures must be scrupulously respected so that
the inlet and outlet AIR from the fans is free to circulate;
3. 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.
2.1. POSITIONING
The machine is delivered from the factory wrapped in estincoil.
Before moving the unit, check the lifting capacity of the machi-
nes used.
Once the packaging has been removed, the unit must be
handled by qualified personnel with the suitable equipment. To
handle the machine: see figure hook up the lifting belts to the
provided eyebolts (as indicated in figure).
WARNING: ALWAYS USE ALL THE PROVIDED EYEBOLTS
Interpose protections between the straps and the machine to
prevent the structure of the unit being damaged by the straps.
It is absolutely forbidden to stand under the unit.
Take into account that when the chiller is working, vibrations
may be generated; it is therefore advisable to install anti-vibra-
tion supports (AVX accessories), fitting them to the holes in the
base according to the assembly diagram.
It is compulsory to provide the necessary technical spaces, to
allow REGULAR AND EXTRAORDINARY MAINTENANCE INTER-
VENTIONS Fasten the unit by checking carefully that its on the
same level; check that easy access to the hydraulic and electric
part is allowed.

5. OPERATING LIMITS
Note:
1 - In summer mode the unit can be started with
external air 46°C/114,8°F and water inlet
35°C/95°F. In winter mode the unit can be star-
ted with external air -15°C/5°F and water
inlet 20°C/68°F. Operate in such conditions is
permitted only for a short time and to bring the
system up to temperature. To reduce the time of
this operation, it is recommended to install
a three-way valve that allows bypassing water
from the system utilities, until the conditions
that allow the unit to work within the permitted
operation limits are achieved.
The devices in their standard configurations are not
suitable for installation in salty environments. For
the operating limits, refer to diagram, valid for AHRI
standard conditions.
Wind breaks should be implemented if the unit is
installed in particularly windy areas, to prevent a
malfunction of the unit.

ATTENTION
The choice and the installation of
components external to the NRL
up to the installer, who must ope-
rate according to the rules of good
technical design and in compliance
with the regulations in force in the
country of destination.
ATTENTION
The hydraulic pipes connecting to
the machine must be properly si-
zed to the actual flow of water re-
quired by the system in operation.
The water flow to the exchanger
must always be constant.
ATTENTION
Carefully wash the plant, before
connecting the unit. This allows
cleaning to remove any residue
such as weld spatter, slag, rust or
other impurities from the pipes.
These substances may otherwise
accumulate in and cause a machi-
ne malfunction. The connecting
pipes should be supported so as
not to weigh, with their weight on
the unit.
ATTENTION
The hydraulic parallel is in charge
of the installer.
NOTE
The drawings are only examples
of the hydraulic circuit.
