Installation InstructionWarning avoid…any obstruction of the unit air outlet or return.Leave 1 meter minimum of free space.…exposure to oil vapours.…installation in areas with high frequencywaves.…any rise in the condensate drain piping.…horizontal condensate drain piping with lessthan 2% slope.…slack on electrical connections.…disconnecting water connections afterinstallation.3

Installation Instruction…exposure to direct sunshine, when unit isoperating in cooling mode; always use shutteror shades…position too close to heating sources whichmay damage the unit.…connecting condensate piping to sewagesystem drain without appropriate trap. Trapheight must be calculated according to the unitdischarge head in order to allow sufficient andcontinuous water evacuation.…only partial insulation of the piping.…installation not correctly leveled which willcause condensate dripping.…flattening or kinking pipes or condensate pipes.4

Installation InstructionInstallationScrew anchorsThe floor mounted unit must be provided withsupposing feet.• Drill four holes for the screw anchors.• Position unit to wall and secure it with screws.• To facilitate cabinet installation, it is suggested touse flathead screws.• To complete the installation make electrical andwater connections as per the diagram inside thecontrol box panel.5

Leave the space shown in the figureabove.The unit coil can be supplied with water connections positioned as requested.NOTE:The connection pipes must be insulated with a condensation-proof material such as polyurethane,propylene or neoprene of 5 to 10 mm thickness.6

Installation InstructionElectrical connections1 2 3 4 5 6Wiring boxIMPORTANT:• Make earth connection prior to any other electrical connections.• Disconnect the power supply to all circuits prior to handling any electrical components.• Before proceeding with the unit connection to the mains supply locate live L and neutral N,then make connections as shown in the wiring diagram.• Ensure that the mains supply connection is made through a switch that disconnects all poles,with contact gap of a least 3 mm.• The fan coil connecting cable as well as accessory wires must be H07 RN-F type (or higher),synthetic rubber insulation with Neoprene coating, according to EN 60335-2-40 andHD277.S1 codes and located in a proper rigid conduit.• For the unit power supply, it is recommended to use cables with a minimum size of 1.5 mm 2 .Control box panel. The control box panel is always positioned opposite the waterconnections.• Two different control box panels are available: one for a unit without electric heater, and onefor a unit with electric heater. Inside each control box panel there is a terminal block for theelectrical connections (see wiring diagrams). After connections have been completed, cablesmust be secured with the cable holders supplied.• If the unit is fitted with an electric heater, this must have a separate power supply.Control3-speed analog switcherCDST-8017

A dirty filter reduces the air flow and unit efficiency.To inspect filter proceed as follows:• switch the unit OFF;• loosen the two screws located at the base of the unit and the corresponding plates;• lower the two guides and withdraw filter;• clean the filter gently with soapy water or with a vacuum cleaner;• reinsert and position the filter in the guides, keeping the photo catalytic filter tabs upwards asillustrated;• return the filter guides to their original position;• tighten the screws and associated plates.It is advisable to clean and if necessary replace the air filter before the winter season.Condensate drainingDuring the summer season check that the condensate drain is free from dust and lint that could8

Installation Instructionclog it, causing condensate water overflow.Heat exchanger coilAt the beginning of any winter and summer season it is advisable to check that the coil fins are notclogged with dust, lint or other foreign matter. Clean the heat exchanger after having removed thesupply grille, taking care not to damage the fins.MotorThe motor is permanently lubricated. Therefore no periodical maintenance is required.9
