686/89/CEE and successive regula tions.
During the installation operate in absolute security, pollution free air and in an area free of obstructions.
Respect the regulations in force in the country in which the apparatus is being installed. Spe cifically relative to
its use, and to the disposal of packing and products used for the cleaning and maintenance of the unit. Respect
the recommendations given by the producers of such products.
Before placing in function the unit, check the perfect connection of the various components and the internal
parts of the system.
Avoid at a ll costs human contact with moving parts and contact w ith the parts themselves.

Spare parts must correspond to the requirements specified by Manufacturer.
In case of dismantling of the unit, respect the anti-pollution regulations in force.
N.B. The installer and the user of the apparatus must take into account, and solve problems, connected with any other
type of risk that may occur to the unit. For example, risks derived from the entrance of foreign bodies, or risks due to the
presence of flammable or toxic gas.
4.3 Preliminary Operations
Check the perfect condition of the various components of the unit.
Control that contained within the packing, there are the installation accessories, and documentation.
Transport the packed section as close as is possible to the intended place of installation.
Do not place tools or weight on top of the packed unit.
4.4 Choosing installation position
Positio n the unit on a solid structure, that will not vibrate, and is capable supporting the weight of the machine.
Positio n the unit in a point where the condensation discharge may occur easily.
Do not position the unit in an area in which flammable gases, acidic or corrosive substances are present. They
may damage various components in an irreparable manner.
Allow a minimum amount of free space as indicated in the figure. This permits ease of installation and
maintenance.
4.5 Connecting accessories
1. Fix the angular fixing clamp
2. Place together the fixing modules
3. Pass the M8 x 25 screw s through the adjacent holes and necessary washers (see diagram)
4. Screw the nut by hand
5. Tighten with an Allen key
IOM / MINIAIR-0507 9
4.6 MINIAIR unit positioning
The unit is equipped with anti-vibration support plates.
As follows are indica tions the various sequence of assembly:
1. Carry out the drilling of the ceiling, and fit the four M8 threaded bolts as indicated in the diagram.
2. Position the unit on the four bolts using the supplied fixing plates.
3. Block the unit tightening the fixing bolts.

To aid the regular flow of the condensation, it is advised to install the unit with a 3mm inc lination towards the
condensation outlet.

4.7 Duct connection
The Ducts must be the correct dimension based on the functions of syste m and the air diffusion characteristics
of the unit fans. A mistaken calculation of the ducting will cause power loss or the intervention of any eventual
devices present on the system.
To prevent the formation of condensation and cut down the sound level it is advised to use internally lined
Ducts.
To avoid the transmission of machine vibrations into the environment, it is advised to fit an anti-vibration joint
between the fans and Ducts. The electrical continuity must be guaranteed between the Ducts and the apparatus
via an earth cable.
4.8 Hydraulic connections
The installation and connecting of the piping is an operation that must be done correctly, otherwise it may
compromise the performance of the system. At worst it may cause irreversible damage to the machine. These
operations are to be effectuated by qualified personnel.
The MINIAIR units are supplied with “female” m oun ted, GAS threaded water coil s.
Extreme caution must be taken during the installation operation, to avoid damage.
The tube path must be studied in such a way to not create obstacles should an eventual extraction of unit coil or
filter be required.
Water inlet and outlet must occur allowing the thermal exchange in counterflow: follow the indications found on
the WATER INLET and WATER OUTLET plate.
Supply a lower valve for the emptying of the water contained in the coil.
Fix securely the tubes to the outside of the unit, so as to avoid offloading the weight onto the coil headers.
Once the connection has been followed, fix the external rubber seals against the panel to avoid passing of air.
The lining must just rest on the panel, to avoid the risk of burning.
Supply an interception valve to isolate the coil from the rest of the circuit in case of extraordinary maintenance.
Should the installation of the apparatus occur in areas with particula rly cold climates, empty the syste m prior to
an extended period of inutilization.
4.8.1 Condensation outlet connection
The stainless steel condensation drip tray is provided with 20 mm outlet diameter.
The system of drainage must provide an adequate trap.
The dimensions and execution of the trap must guarantee that H 50 mm.
IMPORTANT: IT IS IMPORTANT NOT TO PLACE
IN OPERATION THE UNIT IF THE FAN OUTLETS
ARE NOT DUCTED OR NOT PROTECTED BY A
SAFETY NET ADHERING WITH REGULATION
UNI 9219 OR SUCCESSIVE.
IOM / MINIAIR-0507 11
The trap must have a tap for correct cleaning of the lower part, and must allow an easy disassembly.
The path of the condensation drainage tube must always have a gradient toward external.
Insure that the condensation run-off tube does not interfere with discharge of the unit.
4.8.2 Water humidifier connection
The evaporative pack section is feeded by water public network (no water pump inside); the feeding system must provide
a valve (supplied by the installer) for the adjustment of the water flow; an excessive quantity may ove rflow the driptray
system present in the system.
For the drainage of the water and the realisation of the trap, see previous paragraph; furthermore it is recommended to
not reduce the diameter of the drainage tube till the sewer outlet, so as to avoid overflow and nasty odours.
4.9 Electrical connections
Qualified personnel according to the supplied schemes must carry out the electrical connections at the control
panel.
Insure that the voltage and the frequency shown on the technical plate correspond to the connecting power
supply.
For the general power supply of the unit and its accessories, the use of adapters, multiple plugs and extension
leads is to be avoided.
It is the responsibility of the installer to insure that the installation of the unit is as close as possible to
the mains power supply, or sufficiently close to protect the electrical parts.
Connect the unit to an efficient power point, using the correct screws as supplied with the unit.
Before starting any operation, insure
that the general power supply has
been switched off.
Connect the unit and its accessories using
adequate wiring for the used power while
respecting the country regulations. The
dimension of the wiring must be enough to
support a voltage drop in start up phase lower
than 3% of the nominal one.
