AIR-COOLED DIRECT EXPANSION UNIT - VERSION
AX
All models have a single refrigerant circuit, and in some cases two
circuits.
See the DIGIT on the previous page.
The compressor pumps the hot refrigerant gas into the outdoor
condenser.
The liquid refrigerant then flows to a liquid receiver installed in
the indoor unit, to ensure a constant flow of refrigerant to the
thermostatic valve and subsequently the evaporator.
Here the liquid refrigerant absorbs the heat from the environ-
ment and changes state, becoming a gas, then returning to the
compressor: the cycle is then repeated.
To ensure the correct discharge pressure of the refrigerant, we
suggest to select a unit provided with fan speed control.
Valves for isolating the refrigerant circuit are supplied as standard
to assist the routine maintenance operations.
The Scroll compressor is fitted with a non-return valve to prevent
the migration of liquid from the outdoor condenser in the sum-
mer, and unwanted flows of refrigerant during start-up.
A second non-return valve, on the liquid line to the outlet of the
condenser, to be fitted by the installer, is recommended during
operation in winter, to prevent the migration of the refrigerant
charge from the liquid receiver to the outdoor condenser, with
consequent low pressure alarms.The units are provided, as stan-
dard, with centrifugal fans.
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 -
VERSION AW
All models have a single refrigerant circuit, and in some cases two
circuits. See the DIGIT on the previous page.
The compressor pumps the hot refrigerant gas into the indoor
condenser made from braze welded steel plates.The liquid refrig-
erant then flows to a liquid receiver installed in the indoor unit, to
ensure a constant flow of refrigerant to the thermostatic valve
and subsequently the evaporator. Here the liquid refrigerant
absorbs the heat from the environment and changes state,
becoming a gas, then returning to the compressor: the cycle is
then repeated. To ensure the correct discharge pressure of the
refrigerant, we suggest to select a unit provided with pressostatci
valve. Remember that circulation pump is NOT selected, nor pro-
vided from Climaveneta.The units are provided, as standard, with
centrifugal fans.
Water condenser
The units are fitted with an internal braze welded steel plate heat
exchanger.
During installation, a pressure control valve should be fitted (avail-
able in the price list) to manage the condensing pressure.
(See the User and Maintenance Manual)
This circuit works with primary water or with a closed circuit
connected to an external Dry Cooler or an evaporative tower.
For “closed” circuits, the water should be mixed with antifreeze
to prevent frost during the winter, with consequent damage to
the systems: see the installation manual to calculate the required
percentage of antifreeze fluid.
The Dry Coolers are supplied as an accessory (see the price list),
while the antifreeze fluid and fluid circulating pump are generally
supplied by other companies.
For “open” circuits, mechanical filters are required to protect
against impurities and prevent the braze welded plate heat
exchanger from blocking.
To reduce energy consumption (pump), a valve should be fitted to
close the circuit when the indoor unit is off.
Note 1: the water-cooled indoor units (AW) come with the
refrigerant circuit completely charged and tested in the factory
before being delivered.

FREECOOLING UNIT – VERSION AF
All models have a single refrigerant circuit, and in some cases two
circuits. See the DIGIT on the previous page.
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 dewatering filter is installed on the liquid line to keep the cir-
cuit 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 reasons the high pressure switch has manual reset. Remem-
ber that circulation pump is NOT selected, nor provided from
Climaveneta. The AF units are provided, as standard, with radial
fans EC.
Condenser
Each unit is fitted with one (for single circuit units) or two (two
circuit units) condensers made from braze welded stainless steel
heat exchangers. Each condenser is fitted with an HP8 automatic
valve to control the condensing phase. In addition, the condensers
are oversized in order to limit pressure drop (and minimise the
power input of the circulating pumps).
The units generally work via closed circuits with dry coolers
cooled by the outside air. To prevent the formation of frost, the
fluid used inside the closed circuit should always contain a per-
centage of glycol, as indicated in this manual, based on the average
minimum temperature reached in the place of installation in the
coldest periods.
The cooling fluid must be circulated by pumps (not supplied as
standard). Suitably-sized dry coolers are available as options.
Water circuit
The unit is fitted with a 3-way modulating valve to control the
flow of cooling fluid to the indoor exchanger on the freecooling
units. The opening and closing signal is generated and completely
managed by the electronic controller on the air-conditioner, so as
to maintain the desired conditions and ensure maximum energy
saving.
DUAL FLUID UNITS – VERSION AD (air-cooled)
& AT (water-cooled)
All models have a single refrigerant circuit, and in some cases two
circuits.
See the DIGIT on the previous page. Each refrigerant circuit
includes the compressor and a pressure-balanced thermostatic
valve (or electronic valve) to ensure stable superheat tempera-
tures. A liquid indicator is fitted before the thermostatic valve to
display the gas charge.A dewatering filter 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 reasons the high pressure switch has manual reset.The AD
and AT units are provided, as standard, with radial fans EC.
Version AD (air-cooled)
A non-return valve should be installed on the liquid line between
the indoor unit and the outdoor unit by the installer.
The units are supplied separately from the outdoor condenser
and are pre-charged with nitrogen. The customer is responsible
for the connection between the two indoor and outdoor units
and for the emptying and charging operations. For these opera-
tions, follow the instructions provided in the installation manual.
Outdoor air-cooled condenser
The air-cooled condenser should be selected from the models
available in the vast range provided by the manufacturer
Water circuit
The unit is fitted with a 3-way modulating valve to control the
flow of cooling fluid to the indoor exchanger so as to maintain
the desired conditions.
In the DUAL FLUID units, the two circuits, direct expansion DX
and chilled water CW, never work at the same time.The direct
expansion circuit DX is used as backup to the chilled water cir-
cuit CW. Activation set points for the two circuits are available
and are described in the User Terminal manual.

ACCESSING THE MAIN COMPONENTS AIU
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 HANDLING AI
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 (< 50°C).

damage that may be due to transport.
In particular, check that the panel where the user terminal is fitted
has not been damaged.
If the side panels have been damaged during transport, they must
be replaced before installing the unit.
