INSTALLATION, OPERATION
AND MAINTENANCE GUIDE
WATER CASSETTES
FIXING THE PANEL
After installation of the unit, mount the grille using the 4 screws provided
(fig. 12).
!
N.B.: It is very important to fix the grille in the right position
for correct connection of the receiver panel to the unit.
Fig. 12
Use a spirit level (fig. 10) to make sure that the unit is level and check
that it is securely fixed to the ceiling. In high humidity environments,
metal supports must be insulated using adhesive insulating material.
Fig. 11
To fix the unit to the ceiling, use the threaded bar and suitable screw
anchors as shown in fig. 09 (material not included in the supply).

ATTENTION!
Catch up the cassette on the four
corners. Don't lift or move the unit
through the exchanger pipelines or
the exhaust pipe condense.
!
- to fix the panel only use the four supplied screws. Do not use other
kinds of screws or you could damage the condensate drain pan.
- Do not bend or narrow the unit piping.
- Do not remove the cap from the unit piping until immediately before
connecting the pipes.
- To prevent deformation of the air intake grille, do not overtighten the
screws.
CHANGE OF AIR AND RECIRCULATION SYSTEM
- Side knockouts allow connection of a duct for fresh air intake and for
conditioning an adjacent room.
- Remove the external prepunched anti-condensate insulator and
remove the knockout panels using a punch.
FRESH AIR RENEWAL
Remove the polystyrene partition and insert the baffle plate.
Use material purchased locally that is suitable for continuous operation
with temperatures of 60°C. The ducts may be in flexible polyester (with
steel spiral core) or in corrugated aluminium lagged with anti-condensate
material (fibreglass 12±25 mm thick). Upon completion of installation,
surfaces that have not been insulated may be covered with anti-
condensate insulating material (e.g.: 6 mm thick expanded neoprene).
Failure to comply with these instructions could cause dripping due
to the condensate; the manufacturer cannot be held responsible
for any damage.
Any additional fan for external air intake (installer's
responsibility) must be connected to the terminal block as per the
enclosed diagrams. Fan operation is in parallel to the damper
(electrothermal control valve), so that it stops when the valve closes.
Install an air inlet grille on the outside, with an inspectable filter holding
frame to prevent the entry of dust and leaves, which could irreparably
obstruct the unit heat exchanger coil.
RECEIVING, STORE AND MOVING THE UNITS
At the moment of the delivery of the unit, make sure that it corresponds
to the one indicated on the transport document. Check the integrity of
the packing and the unit. Should there be any differences with the original
order or any damages, anomalies, or incomplete supply, please point
it out on the delivery note and inform the firm straight away. Never install
or use damaged apparatuses. The unit can be stored in room protected
from bad weather with temperature between the -20°C and the +55°C.
Transport the packed unit near as possible to the installation place. To
avoid any damage to the unit, the plastic part (frontal panel and grille)
are furnished separately. The handling and the installation could be
facilitated cy use of an elevator(fig. 07).

SELECTION OF CASSETTE INSTALLATION LOCATION
!
RECCOMENDATION!!
- The unit must be installed in a solid and vibration-free ceiling.
- There should be no obstruction of the air flow into and out of the unit
and the air should be evenly distributed throughout the whole room.
- Do not install the unit near sources of heat, steam or inflammable
gases.
- Install the unit near an electric socket or connect it directly to the
power supply.
- Do not install the unit in a place, which is exposed to direct sunlight.
- The selected place should allow easy drainage of the condensed
water.
- Periodically check appliance operation and leave sufficient space for
maintenance around the appliance, as shown in the figure 08.
- Install the unit so that the filter is easily accessible.
INSTALLATION
FIXING THE CASSETTE
Select a place of installation where there can be a clearance of a least
100 cm (see fig. 07) around the appliance. Make sure that the installation
does not interfere with existing electric wiring or plumbing. Establish the
position and size of the hole in the ceiling using the external diameter
of the cardboard mounting template (fig. 08).
