DUC T SIZE
A minimum of 6” round duct must be used
to maintain maximum airflow efficiency.
Flexible ducts are provided for convenience,
always use rigid type metal ducts if available
to maximizing airflow.
Also use calculation (on left) to compute
total available duct run when using elbows,
transitions and caps.
ALWAYS, when possible, reduce the
number or transitions and turns. If a long
duct required, increase duct size from
6” to 7 or 8”.
If a reducer is used, install a long reducer
instead of pancake reducer. Reduce duct
size as far away from opening as possible.
If turns or transitions are required:
Install as far away from opening and
as far apart, between 2, as possible.

OPERATIONS
Read all instructions in this manual before operating the appliance.
Save these instructions for future reference.
Always leave safety grills and filters in place. Without these components,
operating blowers could catch on to hair, fingers and loose clothing.
NEVER dispose cigarette ashes, ignitable substances, or any foreign
objects into blowers.
NEVER leave cooking unattended. When frying, oil in the pan can
easily overheat and catch fire. The risk of self combustion is higher
when the oil has been used several times.

MAINTENANCE & CLEANING
Surface Maintenance:
Clean periodically with hot soapy water and clean cotton cloth. Do not
use corrosive or abrasive detergent (e.g. comet powder scrub, EZ-Off
oven cleaner), or steel wool/scoring pads which will scratch and
damage surface.
For heavier soil use liquid degreaser such as ‘Formula 409’ or ‘Fantastic’
brand cleaner.
After cleaning, you may use non abrasive stainless steel polish/cleaners
such as 3M or ZEP, to polish and buff out the stainless luster and grain.
Always scrub lightly, with clean cotton cloth, and with the grain
Stainless Steel Filters:
The Metal Filters fitted by the factory are intended to filter out residue
and grease from cooking. It need not be replaced on a regular basis but
are required to be kept clean.
Filters should be cleaned after every 30 hours of use. There is a timer
display on the panel indicating the hours of operation, and will alert you
when the hood operates for 32 hours

detergent and leave to soak.
Dry filters and re-install before using hood.
Counter can be reset by continuous pressing the ‘+’ button after turning
off the range hood.
Hood Cleaning
The saturation of greasy residue in the blower and filters may cause
increased inflammability. Keep unit clean and free of grease and residue
build-up at all times to prevent possible fires.
Filters must be cleaned periodically and free from accumulation of
cooking residue (see cleaning instructions inside). Old and worn filters
must be replaced immediately. Do not operate blowers when filters are
removed. Never disassemble parts to clean without proper instructions.
Disassembly is recommended to be performed by qualified personnel
only. Call our service center for removal instructions.
Stainless steel is one of the easiest materials to keep clean. Occasional
care will help preserve its fine appearance.
Cleaning tips:
* Hot water with soap or detergent is all that is usually needed.
* Rinse with clear water. Wipe dry with a clean, soft cloth to avoid water
marks.
* For discolorations or deposits that persist, use a non-scratching
household cleanser or stainless steel polishing powder with a little
amount of water and a soft cloth.
* For stubborn stain, use a plastic scouring pad or soft bristle brush
together with cleanser and water. Rub lightly in direction of polishing
lines or “grain” of the stainless finish. Avoid using too much pressure
that may mar the surface.
* Do not allow deposits to remain for long periods of time.
* Do not use ordinary steel wool or steel brushes. Small bits of steel may
adhere to the surface causing rust.
* Do not allow salt solutions, disinfectants, bleaches, or cleaning
compounds to remain in contact with stainless steel for extended
periods. Many of these compounds contain chemicals that may be
harmful. Rinse with water after exposure and wipe dry with a clean cloth.
* Painted surfaces should be cleaned with warm water and mild detergent
only.
