Furnish and install temperzone fan coil units as indicated on the schedule.

Base Unit – The chassis shall be fabricated of galvanised steel with moulded plastic fascias, and insulated with closed cell foam on the discharge side of the fan. The unit shall be complete with water coil, one or more centrifugal fans, condensate drain tray and enclosed electrical box. Units shall have mounting holes on the top side.

Coils – Coils shall be comprised of die formed plate type aluminium fins mechanically bonded to high efficiency seamless inner rifled copper tubing. Water connections shall be male threaded. Cooling coils shall have a manual air vent.

Fan/s - Fans shall be centrifugal, forward curved, direct driven by a permanent split capacitor motor with bearings oiled for life. Each impeller shall be statically and dynamically balanced. Motors shall be 6 pole type or 4 pole type operating off a single phase power supply. Motors shall have 3 speed windings.

Drain Tray – Drain tray shall have a slope for inducing a positive drainage with the unit level. The tray shall project under the entire length and width of the coil including headers and return bends.

Filters – Filters shall be removable, washable and mounted in a plastic frame. Filters may be accessed via a hinged access panel on the underside of the unit.

Insulation – The base unit shall be insulated with closed cell foam to ensure no particles are introduced into the air stream. Insulation shall be foil faced and meet fire test standards AS 1530.3 (1989) and BS 476 parts 6 & 7.
