Tornado Mini Use, Care, and Installation Guide
ZEPHYRONLINE.COM
Installation Instructions
Mounting Height, Clearance, & Ducting
36"
Min 20” - Max 36” (electric cooktops)
Min 24” - Max 36” (gas cooktops)
A minimum of 6” round or 3-1/4” x 10” rectangular duct must
be used to maintain maximum air flow eciency. Ducting
has a strong eect on the air flow, noise, and energy use of
the fan. Use the shortest, straightest duct routing possible for
best performance, and avoid installing the fan with smaller
ducts than recommended. Insulation around the ducts can
reduce energy loss and inhibit mold growth. Fans installed
with existing ducts may not achieve their rated air flow.
Always use rigid type metal ducts only. Flexible ducts could
restrict air flow by up to 50%.
Also use the ducting calculation sheet (on page 8) to
compute total available duct run when using elbows,
transitions and caps.
ALWAYS, when possible, reduce the number or transitions
and turns. If long duct run is required, increase duct size.
If turns or transitions are required; install as far away from
hood duct output and as far apart, between the two as
possible.
Minimum mount height between range top to hood bottom should be no less than 20” for electric
cook tops and 24” for gas cook tops.
Maximum mount height should be no higher than 36”.
It is important to install the hood at the proper mounting height. Hoods mounted too low could result
in heat damage and fire hazard; while hoods mounted too high will be hard to reach and will lose its
performance and eciency.
If available, also refer range manufacturer’s height clearance requirements and recommended hood
mounting height above range. Always check your local codes for any dierences.
For shipment and installation damages:
►Please fully inspect unit for damage before installation.
►If the unit is damaged in shipment, return the unit to the store in which it was bought for repair or
replacement.
►If the unit is damaged by the customer, repair or replacement is the responsibility of the customer.
►If the unit is damaged by the installer (if other than the customer), repair of replacement must be
made by arrangement between customer and installer.

Installation Instructions
Ducting Options
►Use single wall rigid metal ductwork only.
►Fasten all connections with sheet metal screws and tape all joints w/ certified Silver Tape or Duct
Tape.
Fire Hazard: NEVER exhaust air or terminate ductwork into
spaces between walls, crawl spaces, ceilings, attics, or garages.
All exhaust must be ducted to the outside, unless using the
recirculating option.

Installation Instructions
Electrical Supply
Electrical wiring must be done by qualified person(s) in
accordance with all applicable codes and standards. Turn o
electrical power at service entrance before wiring.
WARNING
For personal safety, remove house fuse or open circuit breaker before beginning installation. Do not
use extension cord or adapter plug with this appliance.
Follow national electrical codes or prevailing local codes and ordinances.
This appliance requires a 120V 60Hz electrical supply, and connected to an individual, properly
grounded branch circuit, protected by a 15 or 20 ampere circuit breaker or time delay fuse. Wiring
must be 2 wire w/ ground. Please also refer to the Electrical Diagram labeled on product.
Grounding
FIG. A
28” Max.
GROUNDING INSTRUCTIONS
This appliance must be grounded. In the event of an electrical
short circuit, grounding reduces the risk of electric shock by
providing an escape wire for the electric current. This appliance
is equipped with a cord having a grounding wire with a
grounding plug. The plug must be plugged into an outlet that is
properly installed and grounded.
WARNING - Improper grounding can result in a risk of electric
shock.
Consult a qualified electrician if the grounding instructions are
not completely understood, or if doubt exists as to whether the appliance is properly grounded.
Do not use an extension cord. If the power supply cord is too short, have a qualified electrician install
an outlet near the appliance.
Position the electrical outlet within the space covered by or above the decorative canopy housing as
space permits and as to not interfere with the round duct. Make sure the outlet is no further than 28”
from the top of the hood body.

Installation Instructions
Mounting the Hood
At least two installers are required due to the weight
and size of the hood.
CAUTION
1. Install optional AK084xAS Stainless Steel Liner.
Review manual included with liner for more details.
2. If no liner is used, cut out an opening in bottom of
the cabinet by following the dimensions in FIG. B.
3. Remove aluminum mesh filter.
4. Lift insert hood into opening and ensure locking clip
has locked into position. (Locking clip is located on
left side of insert hood. FIG. C.
5. Fasten (2) #6 screws into the rear long side of insert
hood. If a liner is used, the screws will go through
the insert hood mounting holes, then the liner and
the wood base. NOTE: Wood blocking may need to
be added to cabinet base if additional support is
needed. See FIG. D and FIG. E.
6. Remove 2 screws from insert hood face plate. The
face plate will drop down and hang by internal
chains. Access to front long side of insert hood is
now available. Fasten (2) #6 screws into the front
long side of insert hood.
7. Re-install insert hood face plate by (4) previously
removed screws.
8. Install duct work and seal all ducting joints and
connections with certified aluminum duct tape.
Install electrical.
9. Remove all packing materials before using insert
hood. Switch power on and check for leaks around
duct tape. Install aluminum mesh filter.

Hood & Filter Cleaning
Surface Maintenance
►Do not use corrosive detergents, abrasive detergents or oven cleaners.
►Do not use any product containing chlorine bleach or any product containing chloride.
►Do not use steel wool or abrasive scrubbing pads which will scratch and damage surface.
Cleaning Stainless Steel
Clean periodically with warm soapy water and clean cotton cloth or micro fiber cloth. Always rub
in the direction of the stainless steel grain. To remove heavier grease build up use a liquid degreaser
detergent.
After cleaning use a non-abrasive stainless steel polish/cleaners, to polish and bu out the stainless
luster and grain. Always scrub lightly, with clean cotton cloth or micro fiber cloth and bu in the
direction of the stainless steel grain.
Aluminum Mesh Filters
The aluminum mesh filters installed by the factory are intended to filter out residue and grease from
cooking. They need not be replaced on a regular basis but are required to be kept clean.
Remove and clean by hand or in dishwasher using a non-phosphate detergent. Discoloration of the
filter may occur if using phosphate detergents, or as a result of local water conditions - but this will
not aect filter performance. This discoloration is not covered by the warranty. Spray degreasing
detergent and leave to soak if heavily soiled.
Dry filters and re-install before using hood.
