[. . . ] (In wintertime the temperature of the air inside the duct will be identical to the outside temperature). The duct connecting the Xcell 270 unit and the air discharge point of the stale air to the outside must also be insulated to prevent condensation on the outside surface of the duct. (During the wintertime the air temperature inside this duct may come close to freezing temperature). For best practice the air discharge and supply ducting on the "in-House" side of the Xcell 270 unit should be insulated but need only be insulated if they pass through an unheated area. [. . . ] It is important that the "vent-hole" in the drain-tube remains positioned higher than the water level in the water trap in which the condensate drain-tube will be placed. Positioning For wall mounting two metal mounting strips are provided on the rear of the unit. Remove the outer strip and refix the remaining metal strip to the unit. Position and secure the `outer' mounting strip level on to the wall using a spirit level. Fit the two self-adhesive rubber plugs (supplied with the unit), on the lower rear corners of the Xcell 270 unit. Electrical Connection Box The electrical connection box must be screwed to a wall or other secure fixing point adjacent to the unit The supplied cable clamp must be fitted to the mains electricity supply cable. When using surface wiring which is not contained in conduit, anchor the cables to the mounting surface along their length and particularly adjacent to the switched connection unit which must have at least 3mm contact separation and the connection box. Ensure that all cable glands are tight to prevent any strain being transferred to electrical connections. Electrical Connection Diagram Ensure the mains electrical supply is switched off before commencing installation. The appliance is Class 1 and it must therefore be earthed Wiring to the appliance must be via a fused and switched connection unit incorporating a double pole isolating switch with 3mm contact separation. The Xcell 270 unit should be connected as the electrical connection diagrams below: The Xcell 270 unit should be wired accordingly to obtain the desired speed: From unit Mains Yellow / Green Brown Grey Black L Blue LOW SPEED N From unit Mains Yellow / Green Brown Grey Black L LINK Blue N MED SPEED From unit Mains Yellow / Green Brown Grey Black L LINK Blue HIGH SPEED N The Xcell 270 unit can also be wired through either one of two three speed selector switches as detailed below: ARRANGEMENT OF THE LIGHT EMITTING DIODES (LED) 7. Red LED - Frost protection active, unit will shut down Protective device against the freezing of heating or plumbing. Only when the problem is repaired and the power reconnected to the unit, will the Red LED go out. The Xcell unit is supplied with 3 factory set speed settings as below: · Speed 1 ­ Night time setting (or when the building is unoccupied) ­ 110m3/h · Speed 2 ­ Normal setting - 175m3/h · Speed 3 ­ Boost setting - 275m3/h Each of these three settings can be adjusted by means of dip-switches mounted on an internal circuit board (as below) to give performance appropriate for room size. Access to this circuit board is through the removable mounting plate situated on the right hand side of the unit. Ensure that the electrical supply is disconnected to the unit before attempting to access the circuit board or adjust dip-switch position. Circuit Board diagram.

Maintenance of the Xcell 270 unit: · Filter replacement l x each year · Heat exchanger cleaning l x each 6 years · Motor / impeller cleaning subject to level of pollution of motors The home owner may clean and /or replace the Xcell 270 filter without professional assistance. Cleaning of the motors must only be carried out by a qualified service engineer. Filters The filters consist of G4 grade filter cloth positioned over a metal frame. The used filter can be removed from the metal frame for cleaning (Filter can be washed with water) Filter Removal and Repositioning · Isolate the Xcell 270 unit from the electricity supply · Open the inspection door by pressing down the two safety catches at the top and bottom of the door with a screwdriver. · Open the inspection door fully · Withdraw the filters from the unit by sliding them out towards you. · Refit new or cleaned filters into same positions in the unit. [. . . ] Disposal of used filters should take into account current waste legislation. Cleaning Heat Exchanger Unit Dependant on circumstances, the heat exchanger unit requires cleaning once every six years as a minimum and once every year as a maximum. · Open the inspection door by pressing down the two safety catches at the top and bottom of the door with a screwdriver. · Carefully withdraw the heat exchanger horizontally from its seating-slides in the unit.
