SECTION 1. CHECKLIST OF ITEMS
Check that the following items have been supplied:
 1 extractor hood (Complete with blower motor, lighting, mains supply cord and
grease filter(s)
SECTION 2. EXTRACTION PERFORMANCE
The most important influence on the performance of the extractor is the design of the
ducting which takes the exhaust air from the extractor to the outside. The duct route
should be a prime consideration during the initial stages of the kitchen design. Please
note the following:
 The extractor is provided with a spigot(s) suitable for connecting 150mm diameter
duct.
 Note: 150mm is the minimum duct diameter consistent with efficient extraction.
 Double blower (fan) models will require two independent duct runs.
 The exhaust duct route length should be kept as short as possible with as few
bends as possible.
 The most efficient configuration is to duct straight through an outside wall so try to
position the cooker against an outside wall when designing your kitchen layout.
 The hood can be vented either to the top exhaust or the rear exhaust position. Use
the position which gives the shortest duct route length and least number of bends.
 A route with more than two 90 degree bends will significantly degrade the
performance of the extraction system. Keep bend radius as large as possible to
maintain a smooth airflow without vortices; avoid kinks in flexible ducting; pull
flexible ducting taut over straight runs to ensure that the internal surface is as
smooth as possible.
 Rigid 150mm diameter (or equivalent rectangular) ducting should be considered for
long or complex duct runs (which must be sourced separately).
 DO NOT REDUCE THE DUCTING DIAMETER OF 150MM AS THIS WILL
REDUCE THE EXTRACTORS PERFORMANCE
