MAINTENANCE

Self Clean Feature
All Zephyr Range Hoods are filter-less and are designed with a self clean feature. The
centrifugal blower system automatically liquefies grease accumulated in its internal housing.
All systems are equipped with dishwasher safe grease containers for its self clean function.
Grease and residue from cooking are often automatically liquefied and can accumulate in the
containers from everyday use. Nevertheless, grease from cooking could also dry and
adhered in its internal housing. Running the self clean function periodically will flush out the
accumulated grease in the range hood’s internal housing.
Cleaning Frequency
Cleaning should be approximately once a month under normal use.
Detergent
Grease cutting detergent such as ‘409’ or its equivalent are recommended.
Safety Grill
Remove both safety grills for cleaning by
simply loosening Philips screws. Clean safety
grills in dishwasher under normal wash cycle.
WARNING: Use with extreme caution as both
safety grills are removed. Beware of blowers
catching on to hair, loose clothing, and fingers.
NEVER leave children unattended.
Self Clean
Turn both blowers on Low speed for cleaning.
For Hurricane series, simply set Timed Delay
Off to 5 minutes as indicated.

Cleaning Tip:
Fill residue containers ¼ full with water before cleaning or during regular use. This will
help to prevent grease from drying and tacking on cup surface.
Warning:
Edges on stainless steel surface are exposed once shield is removed. Clean around
edges with extreme care and we recommend the use of latex cleaning gloves.
MAINTENANCE 6
With nozzle on ‘spray’, squirt ‘409’ detergent
directly onto blower blades 30-35 times.
Repeat with second blower. Allow self
cleaning to run for 5 minutes before switching
off. (If desired, spray water to rinse off detergent after
completion of the cleaning cycle and run for another few
minutes)
Remove residue containers by gently sliding
out with both hands. Clean in dishwasher
under normal wash cycle.

QuattroVent Channels
The QuattroVent Air-Curtain channels are
adjoined to its two main blowers and share the
same internal housing. No further cleaning is
required after the self clean is completed.
Clean residue around the channels surface
with ‘409’ and a cotton cloth regularly.
Replacing Lights
All light bulbs included are 40W appliance bulb. Replace with 60W bulbs if brighter
illumination are desired. Remove light shield according to instructions on page 6.
Warning: Edges on stainless steel surface are exposed once shield is removed. Replace
bulb through opening with extreme care. We recommend wearing of latex gloves.
Surface Maintenance
Clean all surface residue with ‘409’ or mild detergent and wipe with a cotton cloth.

INSTALLATION NOTES
Step 6:
A damper (not included) should be installed to prevent back-draft where needed. A damper might also be required
local codes in order to qualify for building inspections. You can purchase dampers from most hardware stores, or call
our service line to order.
When a damper is not installed, a starting collar is provided in order to increase and raise the duct opening clearance
above the cabinet's base. Snap the adaptor's smaller end to hood's duct opening and secure by drilling 2 pilot holes
and fasten with screws (as shown on step 6, page 10).
Step 9:
The hood should NEVER be installed so that the front is
tilting downward. This will cause grease to back flow to the
front instead of the rear. ALWAYS level the hood or slightly
tilt front of hood upward. Some models includes 2 pre-
installed bumpers on the rear (or top) to aid the hood front
tilt upward when installed. Remove the bumpers simply by
peeling off if hood is preferred to be installed leveled. (refer
diagram)
Step 12:
A connector locking the electrical wiring on the electrical box is recommended and might be required by local codes.
Check with local inspectors, purchase and install the appropriate connector in order to meet all mandatory codes.
Call our service line to order connector.

Check if unit has been plugged in, make sure that all power
has been turned back on and all electrical wiring are
properly connected.
Blower blade unit might have been mounted too low and
scraping the bottom or jammed. Loosen hex screw on
blade unit and adjust to proper height.
There might have been foreign particles left within the
discharge opening or rocks, leaves, branches, etc. that
might have fell in from old duct work. Disconnect duct work
to inspect and remove any foreign particles.
Unit might not have been secured properly on cabinet. Or
cabinet might need to be further secured into studs on wall.
Our blowers are designed to perform up to 695 cfm. A
properly functioning motor itself should be relatively quiet.
Nevertheless, due to vacuum created by the suction, noise
level up to 5.5 sones will be generated when both blower
unit is turned on at its maximum speed. Employ both
blowers at maximum speed only when needed (heavy pan
frying, wok cooking etc.) Employing low speeds or a single
blower will suffice moderate cooking such as steaming,
broiling etc.
Light bulb might need to be replaced. On some instances,
the fragile bulb could have been damaged during the
shipping process. Simply replace with a 40 or 60W
appliance bulb.
Grease flow will vary by the amount, methods and types of
cooking. If pan-frying is frequent accompanied by
steaming, vapor from steam will liquefy accumulated
grease in its internal housing and flows in the containers.
No grease collected in the residue containers is normal
until the self clean function is completed. Clean blowers
approximately once a month as instructed to avoid
clogging.
Tubes connected to the internal housing might have been
clogged due to lack of cleaning. Or hood might not have
been leveled when installed. Unclog tubes or re-install
hood (refer page 16).
The self clean feature cleans only the internal housing
within the range hood. Remove safety grill to clean in
dishwasher and clean all surface periodically as instructed.
Check duct size used, duct size should be at least 6“ or 3-
1/4 x 10”. Range hood WILL NOT function properly with
the insufficient duct size.
Check if duct is clogged or if damper unit is not opening
properly. A tight mesh on a side wall cap unit might also
cause restriction to the air flow.

TROUBLE SHOOTING 18
11. Cooking fumes and smoke dissipates
before it reaches the blower.
Use a damper type sidewall cap.
Reduce the number of elbows and length of duct work.
Check if all joints are properly connected, sealed and
taped.
Check if unit is installed at the recommended height
(page 9). The range hood should also be able to cover
the entire cooking area from left to right and most areas
from rear to front.
Open doors and windows might also distract air flow
before it reaches the blowers.
Make sure blowers are on high speed for heavy cooking.
