1.3 Unit description
RAARIA MULTI R32 is a heat pump outdoor unit that can be
coupled to indoor units of the same series for the air-condi-
tioning of small/middle-sized rooms. Designed for outdoor in-
stallation, it is suitable for use in residential and small business
premises.
The rotary-type compressor is controlled via DC-Inverter control
with continuous modulation from 20% to 110%, thus ensuring
high energy standards. The fan DC motor improves performance
and sound comfort. The expansion valve electronically optimises
the flow of refrigerant within the circuit.
The R32 refrigerant allows high yields, thus placing R
AARIA MULTI R32 among the most efficient devices on the mar-
ket.
1.4 Safety and adjustment devices
The device safety and setting are achieved thanks to
—compressor motor thermal protection, which is triggered in
case the current consumed by the compressor is excessive
—gas delivery temperature sensor, which transmits the de-
tected value to the electronic board that is triggered in case
of overtemperature (116°C)
—anti-freeze sensor, which transmits the temperature value
as detected by the heat exchanger to the electronic board
that is triggered when the heat exchanger is clogged by
frost formations
—suction temperature sensor, which transmits the detected
value to the electronic board that is triggered in order to
adjust the flow of refrigerant gas or to stop the unit in case
of overtemperature (40°C)
—outdoor air temperature sensor, which transmits the de-
tected value to the electronic board that is triggered in or-
der to adjust the operation of the unit indoor components
to the variation of weather conditions
• Model 355 - 370 - 475 - 485
—high pressure switch, which transmits the detected value
to the electronic board that is triggered in case of pressure
too high or malfunction of the pressure switch, stop of the
unit; it automatically resets up to 3 times in 60 minutes,
then the restart needs recovery by removing and restoring
the power supply
—low pressure switch, twhich transmits the detected value
to the electronic board that is triggered in case of pressure
too low or malfunction of the pressure switch, stop the
unit; it automatically resets up to 3 times in 60 minutes,
then the restart needs recovery by removing and restoring
the power supply

GENERAL INFORMATION
1.10 Cooling circuit
The cooling circuit is of the heat pump type with a refrigerant gas
reversal cycle. The source fluid utilised is the outdoor air, while
the utility-side fluid is the air inside the rooms.
During the wintertime, the heat pump extracts the thermal en-
ergy from the outdoor air and delivers it to the room air, thereby
heating it. During the summertime the cycle is reversed, and the
thermal energy is extracted from the room air, which is cooled,
and is delivered to the outdoor air.

2.6 Place of installation
The location of RAARIA MULTI R32 devices must be deter-
mined by the system's designer or by another competent per-
son, and must take into account the technical requirements, as
well as any current local regulations that require specific permits
to be obtained. (e.g.: zoning, architectural, environmental pro-
tection, etc.).
It is therefore recommended to obtain all the necessary permits
before installing the device.
RAARIA MULTI R32 is designed for outdoor installation.
Avoid:
—positioning the unit in air shafts and/or basement window
wells
—any obstacles or barriers that will cause the expelled air to
recirculate
—locations with aggressive or explosive atmospheres or with
inflammable fluids
—confined locations in which the device's sound levels
might be compounded by reverberations or resonances
—proximity to bedrooms and rooms for resting

20
INSTALLATION
—positioning in corners where dust, leaves, or any other
materials typically accumulate, which could compromise
the device efficiency by obstructing the airflow
—situations in which the air expelled from the device might
enter the habitation through doors or windows, thus cre-
ating an inconvenience for the people inside
—situations in which the air expelled from the device will
encounter resistance from opposing winds
—direct exposure to sunlight and proximity to heat sources
9
Avoid placing the unit less than 1 metre away from radio and
video systems.
9
If the unit is installed in a windy location, fit an anti-wind
grille to protect the fan and check the correct functioning of
the unit.
9
Decide where to place the unit considering the length of
cooling lines and the maximum difference of height al-
lowed between the devices.
2.7 Recommended distances
The distances for the device installation and maintenance are
shown in the figure. The indicated spaces are necessary in order
to prevent the airflow from being blocked, as well as to allow
