REFRIGERANT CIRCUIT
All models have a single refrigerant circuit, and in some cases two
circuits.
Each refrigerant circuit includes the compressor and a pressure-
balanced thermostatic valve (or electronic valve) to ensure stable
superheat temperatures. A liquid indicator is fitted before the
thermostatic valve to display the gas charge.
A filter-drier is installed on the liquid line to keep the circuit clean
and free of dirt. The refrigerant circuit is also fitted with high and
low pressure switches.
The low pressure switch has automatic reset, while for safety rea-
sons the high pressure switch has manual reset.
The compressor pumps the hot refrigerant gas into the con-
denser. The liquid refrigerant then flows to a liquid receiver (fitted
with safety valve) installed on the indoor unit, to ensure a con-
stant flow of refrigerant to the thermostatic valve and subse-
quently the evaporator. Here the liquid refrigerant absorbs the
heat from the environment and changes state, becoming a gas,
then returning to the compressor: from this point onwards the
cycle repeats itself.
AIR-COOLED DIRECT EXPANSION UNIT - VERSION
AX
The AX series units use air as the cooling fluid, and are therefore
combined with an outdoor air-cooled condenser (supplied sepa-
rately). The MO ULATING version features speed control for
the fans on the condenser, so as to maintain correct refrigerant
condensing pressure. The AX units are supplied with valves for
closing and isolating the refrigerant circuit and to assist service
operations. A second non-return valve, to be fitted by the
installer at the condenser outlet on the liquid line, is recommend-
ed during operation in winter, to prevent migration of the refrig-
erant charge from the liquid receiver to the outdoor condenser,
with consequent low pressure alarms.
The AX units are supplied as standard with EC radial fans in the
standard version.
Air-cooled condenser, outdoor installation
The indoor unit can be connected to different types of outdoor
condensers, standard or low noise versions, with special treat-
ments on the coils.
For the corresponding information refer to the manual on out-
door air-cooled condensers.
Note 1: the outdoor units and condensers are supplied separately
Note 2: the indoor unit is delivered charged with nitrogen at near
atmospheric pressure. The outdoor condenser, on the other hand,
is supplied pressurised with dry air (around 3 bar.)
Note 3: the customer is considered responsible for making the
correct connections between the indoor and outdoor unit, as
clearly indicated in the Installation manual, and for ensuring the gas
and oil charges, where necessary.
WATER-COOLED DIRECT EXPANSION UNIT - VER-
SION AW
The AW series units use water as the cooling fluid, therefore each
refrigerant circuit is combined with a plate heat exchanger
installed on the unit, suitably sized to ensure minimum water side
pressure drop and consequently reduce the power consumption
of the water pump.
Remember that the units are supplied without the system circu-
lating pump.
The AW units are supplied as standard with EC radial fans in the
standard version.
Water-cooled condenser
The units are fitted with an internal braze welded stainless steel
plate heat exchanger.
The units for applications with well water are supplied with a
pressure control valve to manage the condensing pressure.
This circuit works with primary water or with a closed circuit
connected to an outdoor dry cooler or cooling tower.
For “closed” circuits, it’s recommended to use water mixed with
antifreeze to prevent ice from forming in winter and consequently
damaging the system: see the installation manual for the calcula-
tion of the percentage of antifreeze to use.
The dry coolers are supplied as an optional accessory, while the
antifreeze and fluid circulating pump are generally supplied by oth-
er manufacturers.
For “open” circuits mechanical filters must be used to trap impu-
rities and prevent blockage of the braze-welded plate heat
exchanger.
To reduce energy consumption (pump), it’s suggested to use a
valve to close the circuit when the indoor unit is off.
Note 1: the AW water-cooled indoor units come with the refrig-
erant circuit completely charged and factory-tested before deliv-
ery.

FREE COOLING UNITS – VERSION AF
The AF series units, in favourable outside conditions, can use the
cooling water to maintain the set environmental conditions with-
out the need for mechanical cooling using the compressor, or to
reduce the cooling load.
The AF series units use water as the cooling fluid, therefore each
refrigerant circuit is combined with a plate heat exchanger
installed on the unit, suitably sized to ensure minimum water side
pressure drop and consequently reduce power consumption of
the water pump.
The AF units are supplied as standard with EC radial fans in the
standard version.
Water-cooled condenser
Each unit is fitted with one (single-circuit units) or two (two-cir-
cuit units) braze welded stainless steel plate condensers.
Each refrigerant circuit features an automatic bypass valve to con-
trol minimum condensing pressure during operation in FC mode.
The units generally work in closed circuits, with outdoor dry
coolers, cooled by the outside air.
To avoid ice formation, it’s recommended to always use a glycol
mixture as the fluid inside the closed circuit, in the percentages
described in this manual based on the average minimum tempera-
ture reached in the installation site in winter.
The cooling fluid must be circulated using pumps (not supplied as
standard).
ry coolers in the correct size are available as options.
Water circuit
The unit is fitted with a modulating 3-way valve to control the
flow of cooling fluid to the indoor heat exchanger for free cool-
ing. The opening and closing signal is generated and managed com-
pletely by the electronic controller on the air-conditioner so as to
maintain the desired conditions and ensure maximum energy sav-
ings.
DUAL FLUID UNITS – VERSION AD (air-cooled) & AT
(water-cooled)
The A and AT series units feature two different cooling systems,
which cannot be active at the same time.
One primary chilled water system (CW) provided by a chiller
installed on site, and a secondary direct expansion system ( X),
which also acts as backup.
The activation set points of these two circuits can be seen in the
user terminal manual.
The unit AT and A are supplied as standard with EC radial fans in
the standard version.
Version AD (air-cooled)
The A series units use air as the cooling fluid, and are therefore
combined with an outdoor air-cooled condenser (supplied sepa-
rately).
The MO ULATING version features condenser fan speed control,
so as to maintain correct refrigerant condensing pressure.
The A units are supplied with valves for closing and isolating the
refrigerant circuit and to assist service operations.
A second non-return valve, to be fitted by the installer at the con-
denser outlet on the liquid line, is recommended during operation
in winter, to prevent migration of the refrigerant charge from the
liquid receiver to the outdoor condenser, with consequent low
pressure alarms.
Outdoor air-cooled condenser
The indoor unit can be connected to different types of outdoor
condensers, standard or low noise versions, with special treatments
on the coils.
For the corresponding information refer to the manual on outdoor
air-cooled condensers.
Note 1: unit and outdoor condensers supplied separately
Note 2: the indoor unit is delivered charged with nitrogen at near-
atmospheric pressure. The outdoor condenser, on the other hand,
is supplied pressurised with dry air (around 3 bars)
Note 3: the customer is responsible for properly making the con-
nections between the indoor and outdoor unit, as clearly described
in this manual, and for ensuring the required gas and oil charge,
where necessary.

ACCESSING T E MAIN COMPONENTS
ENACCURATE AX - AW - AD - AT - AF 15
The air-conditioner is accessible from all sides by removing the
various panels.
The front and/or side panels are opened in 2 different ways:
FRONT PANELS
All the front panels are hinged and fitted with locking latches and
seal.
All the front panels are opened and closed using a tool (typically a
screwdriver) to open and close the latches.
Once the latches have been opened, the front panels can be
swung open and then removed vertically to simplify the service
operations on the air-conditioner, especially where there is little
space available.
Opening the front panels provides access to all the components
in the air-conditioner involved in routine maintenance.
The number of front panels depends on the capacity of the air-
conditioner.
SIDE PANELS
All the side panels are accessible and removable.
Nonetheless, these do not need to be removed for routine main-
tenance operations. This means that, if necessary, a series of units
can be installed next to each other.
The side panels are fastened by screws.
These are accessible directly on the side panel by removing the
black plastic caps.
BACK PANELS
Fastened by normal self-tapping screws, these are not accessible
as when installed the back of the unit is against the wall.
INSIDE PANELS
The compartment that contains the fans and the heaters is pro-
tected and insulated by a metal plate.
This is for safety reasons, so as to not have to shut the unit down
during normal maintenance operations.
WARNING: before restarting the air-conditioner, always
check that all the panels have been correctly replaced.

TRANSPORT AND ANDLING
16 EN ACCURATE AX - AW - AD - AT - AF
Move the air-conditioner, which must not be reclined or tipped
over, nor exposed to the elements, as near as possible to the site
of installation before removing the packaging and the pallet.
The units can be lifted:
- using a forklift, sliding the forks through the openings in the pal-
let;
- using fabric slings underneath the unit, making sure that when
the slings are in tension these do not apply pressure on the top
edges.
The air-conditioner must be stored indoors, preferably in its own
packaging, and protected against excessive humidity (<85% RH)
and temperature (> -20°C , < 50°C).
