Ductwork
—
Air distribution ductwork must be designed to allow for the specified air flow without
excessive pressure levels. The unit should be situated as close as possible to the point
of use to prevent unnecessary long runs of ductwork.
—
Sheetmetal ductwork is recommended for use with all Armcor Air Solutions equipment.
—
Ducts should be insulated in accordance with
BCA Section J-5
.
—
Fan inlet conditions can affect the fan performance, particularly where duct bends
cause a non-uniform flow and swirl at the inlet. To reduce losses due to fan systems
effect, adequate length of straight duct between any elbow and the fan inlet should
be provided or turning vanes used in the elbow.
—
Poor fan outlet conditions will also affect the fan performance. We recommend a
minimum of 1000mm of straight duct directly after the fan outlet.
Filters
—
50mm panel filters are a minimum recommendation for all equipment.
—
Filters must be fitted to fresh air and/or return air. Where there is no provision
for filters within the unit, the installing contractor is responsible to incorporate filters
in the ductwork system external to the unit.
—
It is recommended that temporary disposable filters are used during construction
and commissioning.
—
Where a Heat Exchanger is incorporated in the equipment, warranty is void if filters
are not fitted.
IMPORTANT: NEVER OPERATE A UNIT WITHOUT FILTERS FITTED TO THE
RETURN AND FRESH AIR INTAKES.
Electrical Requirements
—
The power requirement and voltage are detailed on the equipment technical
specifications (available on our website
www.armcor.com.au
) and are on the
identification/serial no. plate attached to each unit.
—
An electrical diagram is attached to the electrical box on the unit.
