Fan Coil Units

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

Base Unit – The base unit shall be fabricated of galvanised steel 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, enclosed electrical box and supply air duct spigot. 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 an adjustment 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. The entire drain tray shall be removable to enable a thorough clean.

Filters – Filters shall be removable, 13 mm thick, washable, rated EU2, and mounted in a plastic frame. Filters may be slid out sideways when a return air duct is used.

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.

Noise Control – Standard capacity units shall have a Sound Power Level (SWL) less than 55 dB(A). Return air plenums shall be insulated with open cell foam for noise attenuation.

Electric Heat - Electric elements shall be fin-tube constructed of stainless steel and include both a manual and auto reset high temperature cutout switches (as required to meet AS/NZS 3350.2.40 1997).
