Water and Drainage – These are dependent on the specific handing of the unit, as defined
during the manufacturing of the order. Should the handing be unsuitable for connection,
please contact our sales office to discuss further.
Electrical Connection – From left or right hand side to suit handing (see 'Water and Drainage'
above).
Drain Tray Removal – Access from the underside of the unit. The drain tray is held in place by
4 retaining screws, 2 on each side of the unit.
Heat Exchanger (coil) removal – Accessed from the underside of the unit with fixing points
on both sides.
Control/Electrical Enclosure – From left or right hand of unit. Minimum 235mm (PROAIR235)
or 270mm (PROAIR270) from underside and 500mm from vertical cover.
Valves – The unit is typically supplied with either project specific (free issued) valves, or
Biddle's standard 4 port offer. The customer is to ensure that isolation valves are placed
suitably close to the unit to allow for disconnection during future servicing and maintenance.
Data Label - Each unit is supplied with a serial number marked on the data label on the
underside of the unit - this should be visible once installed to allow for accurate unit
identification.
Failure to provide adequate access will prevent adequate servicing and
maintenance of the unit that can negatively impact the life expectancy of the
unit and any warranty.
Installing the Fan Coil Unit
None of the connection points, spigots/drain connection/coil connections/controls enclosure,
are designed to be load bearing or support external equipment during installation or thereafter.
The unit must be installed horizontal and level across both its width and length, however a
slight incline of 2 or 3 degrees towards the condensate drain point is acceptable.
Each unit is provided with four fixed hanging points. These are designed for a M10 fixing or
drop rod supports to take the full weight of the unit. Mechanical fixings must be used to fix the
appliance - adhesives are not deemed suitable.
