Installation - Fix the unit on a ceiling or a solid support without vibrations. - Do not install the appliance in a space exposed to sunlight or heat sources, vapor or flammable gas. - Install the cassette so that the inlet and outlet air ducts are not obstructed; the air must circulate freely throughout the area that has to be air-conditioned.
PANEL FIXING Fixed tightly the unit, the plastic panel must be mounted using only and exclusively the screws provided (holes position in Fig. C) To prevent the deformation of the grid, be careful not to overtighten the screws. Fig. C RENEWAL SYSTEM AND REMOTE AIR DISTRIBUTION The side openings allow the separate realization of an external air intake duct for the renewal and of an air hose duct for an adjacent room.
HYDRAULIC CONNECTIONS A correct installation provides also the anti-condensate insulation of the water pipes. Always use adequate keys to avoid the damage of the connections. The disposition of the water connections for the 2-pipes cassette is reported in fig. E, while the one for the 4-pipes cassette is reported in fig.
VALVES CONDENSATE TRAY MOUNTING (optional) The auxiliary tray collects the condensate formed near the water connections and the valves. Fix the tray to the structure with the screws provided in the position shown in Fig. H., making sure pipes and insulation do not tilt it, hindering the drain. TYPE 070/090/094 Fig.
CLEANING AND MAINTENANCE Before maintenance, make sure the power of the unit is turned off. Only qualified specialists can intervene. The only component of the cassette that needs cleaning and maintenance is the filter, placed on the air intake (unless there is the breakage of other components). The filter must be cleaned with every season change, using a vacuum-cleaner or brushing it.
MALFUNCTIONS AND CORRECTIVE ACTIONS FAN DOES NOT RUN CORRECTIVE ACTIONS - make sure that the machine is powered; - check if some switches or fuses are; - check the correct wiring of the unit (qualified personnel only) - check if the thermostat is set in the right way. LOW AIR FLOW CORRECTIVE ACTIONS - select an higher fan speed;...
