4. Installation
4.1. Preparing for installation
Remove the cardboard packaging and all external polystyrene side protections before installation. The unit should always
be handled by two people and should only be grasped on the adequately resistant points (main metal structure), taking
care not to damage the less resistant parts, in particular the filters, grills and control.
If the optional feet are present, install them as described in the specific paragraph. For units
equipped with a cabinet, it must first be removed by following the procedure below.
Using a Phillips screwdriver with a maximum diameter of 3.5 mm, remove the screw from the hole at the right end of the
front intake grille. Rotate forward and lift the suction grille to remove it.
Remove the screws that secure the cabinet to the fan-coil structure, behind the intake grille.
Remove the screw at the right end of the discharge grille (if it has blades pointing forwards) or left end (if it has blades
pointing backwards) and remove the grille by releasing it from the side opposite the screw.
Remove the screws securing the cabinet beam to the fan-coil structure and remove the cabinet by lifting it upwards.

At the end of the installation, it will be necessary to reassemble all the components in the reverse order in which they
were disassembled. It is absolutely forbidden (serious risk of personal injury) to use the unit if any components have been
correctly reassembled.
The unit has four slots for fixing it to the wall using dowels and screws.

Secure the unit to the wall with four screws (washers may be required depending on the size of the screw heads). At the
end of the installation the unit must be perfectly horizontal or with a slight slope in the direction of the condensate drain.
Installations with a slope opposite to the condensate drain are not permitted as this can prevent natural drainage.
4.2. Positioning
The unit must be installed on a wall which must be perfectly vertical (90° to the floor).
Observe the minimum dimensions shown in the figure, which are necessary for the smooth installation and correct
operation of the unit.
IRIS SLIM / IN
Rossato Group Srl 13

The unit must not be exposed to direct sunlight or heat sources. Provide a position in the room so that the unit can treat
the whole room uniformly, without directly hitting the occupants with the air flow.
4.3. Electrical supply
4.3.1. Hydraulic connections
The machine is equipped with a battery suitable for working with water, possibly mixed with glycol.
To avoid the formation of condensation on the surface of the unit during the summer period, when the fan is not running, it
is recommended to interrupt the flow of chilled water by means of a motorised valve.
All pipes, particularly those for chilled water, must be insulated to prevent condensation dripping.
To facilitate maintenance, it is advisable to provide manual ball valves, so that the machine can be shut off from the
system.
When connecting the pipes, in order not to touch the coil and valve pipes, it is recommended to use a spanner and
counter spanner.
The valves can be pre-installed or supplied in kit (to be assembled by the installer).
In any case, take care to respect the indications regarding water inlet and outlet.

After completing the hydraulic installation and charging the system, the coil must be vented using the needle valve
provided. Repeat the venting operation after starting the circulation pump, until it is certain that all bubbles have been
eliminated.

Before connecting the condensate drain pipe, check that the main tray is level or slightly sloping towards the drain. In the
vertical version, also check that the auxiliary tray is correctly fixed to the side and that the rubber elbow is adherent to the
drain of the main tray. In horizontal versions, check that the rubber discharge pipe is adherent to the metal elbow of the
main pan.
A = Gomito di gomma
B = Vaschetta ausiliaria
Use a drain pipe with a diameter of at least 16 mm. It is advisable to use a white water drain; if there is a possibility of
odours rising, a siphon must be installed. The slope of the pipe must be constant and not less than 1%; if it is necessary
to overcome counter-slopes, install a drain pump (follow the instructions on the pump installation sheet), the pump must
in any case be installed below the level of the unit's tray.
For vertical units, connect the condensate drainage pipe to the auxiliary tray. For horizontal units, extend the existing
drainage pipe, which is connected to the metal elbow of the main tray. When mounting the front panel, make sure that the
drainage pipe is never at an angle.
After completing the installation of the condensate drain, pour at least 2 litres of water into the tray with a bottle (slowly, in
small doses over a period of 5 minutes) and check that it flows correctly.
3-Way Valve Kit Installation (Optional Accessory)
The valves can be supplied either assembled to the unit or in kit form (disassembled components). Valves supplied in kit
form must be assembled to the unit as shown in the figures in the dedicated section.
Always place flat fibre or rubber seals between each hydraulic element (e.g. between valve and pipe or between battery
and pipe).
Insulate all pipes (upstream and downstream of the valves) and the valve body itself to prevent condensate dripping out
of the auxiliary tank.
Make sure that the actuator is facing upwards or at least horizontally to the valve body. Installations with the actuator
facing downwards are not permitted.

A = Actuator
B = Protecting cap
4.3.2. Electrical connections
Provide a manual disconnect near the unit so that it can be disconnected from the power line during maintenance
operations.
Provide a fuse or circuit breaker to protect the unit.
The power supply cables must be sized taking into account the maximum absorption of the machine, as indicated on the
label and in the technical manual, in any case not less than 0.75 sq. mm.
Check that the mains voltage and frequency is 230 V - 50 Hz.
Before carrying out any maintenance work on the machine, make sure that the main power supply is switched off and
cannot be switched on unintentionally. Before opening the electrical box, wait at least 60 seconds after the power supply
has been switched off. In any case, after opening the electrical box, before touching the board or the electrical
connections, check with a tester (set to V direct) that the voltage at the ends of the capacitor is lower than 38 V (for this
purpose, measuring points are provided on the board itself). Do not continue with the intervention if the voltage is higher
than 38 V.
