IMPORTANT SAFETY NOTICE
READ AND SAVE THESE INSTRUCTIONS
a) Use this unit only in the manner intended by the manufacturer, if you have questions,
contact the manufacturer.
b) Before servicing or cleaning unit, switch power off at service panel and lock the service
disconnecting means to prevent power from being switched on accidentally. When the
service disconnecting means cannot be locked, securely fasten a prominent warning
device, such as a tag, to the service panel.
a) Never leave surface units unattended at high settings. Boil overs cause smoking and
greasy spillovers that may ignite. Heat oils slowly on low or medium settings.
b) Always turn hood ON when cooking at high heat or when flaming food.(i.e.Cherries
Jubilee, Peppercom Beef Flambe’).
c) Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or filter.
d) Use proper pan size. Always use cookware appropriate for the size of the surface element.
e) Keep fan, fillters and grease laden surfaces clean.
f ) Use high setting on hood only when necessary.
g) Don’t leave hood unattended when cooking.
h)Always use cookware and utensils appropriate for the type of and amount of food being prepared.
a) SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal tray, then turn off the
burner. BE CAREFUL TO PREVENT BURNS. If the flames do not go out immediately,
EVACUATE AND CALL THE FIRE DEPARTMENT.
b) NEVER PICK UP A FLAMING PAN – You may be burned.
c) DO NOT USE WATER, including wet dishcloths or towels – a violent steam explosion
will result.
d) Use an extinguisher ONLY if:
1) You know you have a Class ABC extinguisher, and you already know how to operate it.
2) The fire is small and contained in the area where it started.
3) The fire department is being called.
4) You can fight the fire with your back to an exit

III. Installation Guidelines
Check the surrounding of range hood. If there
are too many windows or doors nearby, it is
advisable to close the windows and doors before
turning on the range hood to prevent the external
convection and affecting the ventilation.
The smoke has to rise up to 10 inches from the
stove/grate to be within the range of venting
efficiency.
The ideal installation height is a distance of
24 to 30 inches from the bottom of the range
hood to the surface of the stove top.
The front, back, right and left of hood must be
in parallel and horizontal level, to avoid the oil
in the oil tub from spilling over. To ensure that
the hood is leveled when installing, it can be
measured by the hook mark for the left and right
side; and the screws fixed securely onto the wall
to ensure the front and back of the hood are parallel.
In order to increase the venting efficiency of the hood, it is recommended to
use the 6 inches duct to maintain the best air flow efficiency; the length of duct
must also be as minimal as possible.
Please do not plug the range hood to the circuit breaker with other high
electricity consumption appliances.
Before installing the hood, please apply fast drying glue to the collar and securely attach
it to the top of the range hood’s vent lid. Install the range hood and attach pipe to the
plastic collar and seal with aluminum tape and prevent steam and smoke leakage.
Too many windows, too much convection

1. Prepare duct location on hood (vertical).
2. Measure and cut out duct and electrical
openings in cabinet or wall to match up
with the hood. Ducting and electrical
dimensions can be found on Page 1.
Note: Makesure duct opening is large
enough to apply aluminum duct tape.
3. Reinforce cabinet bottom with wood strips
if additional strengthening is required or
if cabinets are framed.
4. Remove bottom panel from hood using
a Philips head screwdriver to remove
each of the (5) screws.
6. Install (4) wood screws to cabinet bottom
5. Stick the two round rubber stands on the
sides of hood’s top. (see Fig 2)
These screwswill be used to secure the
hood to the cabinet.
7. Lift hood onto screws located on cabinet
bottom and lock into place. Make sure
all (4)key-holes cover the screws. Tighten
each screw to secure hood to cabinet.
8. Install electrical.
9. Install duct work and seal with aluminum
duct tape.
10. Power up hood and check for leaks around
duct tape and test all functions.
11. Reinstall bottom panel and re-connect
lighting harness.

VI. Surface Maintenance
A. Surface Maintenance
1. Please clean the range hood surface regularly with warm soapy water
and wipe with a cotton cloth to prevent grease from accumulating.
2. Please do not use harsh cleansers or coarse material to clean the surface
because that will damage the surface.
3. A non-invasive stainless steel polish is recommended to polish the surface
after cleaning.
4. Please use soft cloth for polishing because it will make your range hood
surface shinier.
5. Please do not use cleaning solutions that have bleach as an ingredient.
B. Surface Cleaning and Maintenance
1. Always disconnect from power supply before cleaning.
2. Clean both exterior and interior of the hood for long
lasting. Do not use abrasive cleanser.
3.The stainless steel baffle fi lters are intended to trap
residue and grease from cooking. Although the filters
should never need replacing, they are required to be
cleaned every 30 days or more often depending on
cooking habits. Filters may be placed in dishwasher at
low heat or soaked in hot soapy water Dry filters and
re-install before using hood.
4. The oil cup in the center of the hood for holding grease
can be detached and cleaned regularly.
5. Make a habit of turning on the range hood first before
turning on the stove to avoid high temperature in the
kitchen.

7.
VII. Remarks
1. When filling the range hood with the cleaner mixture, use only the special jar provided
with the range hood and take precautions not to overfill the cleaner storage unit.
2. Check the oil retainer during the cleaning process to prevent oil spillage. Do not allow
dirty oil to exceed the marked level.
3. Do not put any other substances into the cleaner compartment unit as this will cause
blockage of its injection hole.
4. The cleaner storing unit and the supplied jar are of identical size.
The cleaner mixture stored can be used for 5 to 6 times. The cleaner storage unit
may be refilled by diluted cleaner mixture every time after use. To prevent overfilling,
5. Always turn the range hood on first before turning the cooktop on as high heat may
damage the range hood.
6. If the supply cord is damaged, it must be replaced by the manufacturer or its service
agent or a similar qualified person in order to avoid a hazard.

三.安裝原則
抽油煙機安裝位置，如在窗上或附近有太多門
窗，請在開動抽油煙機前，先關閉門窗，以免
空氣對流大而影響吸力，因當油煙上昇未至10
英吋之有效吸力範圍 ，則無法充分發揮抽油煙
最佳效果 。
1. 周圍環境(圖一):
安裝高度自本機底板至煮食爐面之距離以24~
30英吋為最理想 。
2. 安裝高度(圖二):
機體應保持前、後、左、右水平，以免氣流箱，
導油盆積油而溢出。
左、右水平可由掛碼調整，前、後水平則由鋼
釘螺絲鎖緊牆壁，以固定標準。
3. 機體應保持水平(圖三):
4. 排風管:
5. 插座安排:
安裝前先以矽利康注入風管圈後將風管崁入，再用封膠封住風管圈。
為增加吸力效能，請配合使用本機出風管接頭
之直徑6英吋排風管 ，排風管長度應以適合長
度最佳，不宜過長。
請勿與烤箱或冰箱等耗電量較高之電器產品共
用一個插座。
