supplied by other than electrical energy, as the cooker hood removes
the air from the environment which a burner or fireplace need for
combustion.
The negative pressure in the environment must not exceed 4 Pa (4*10-
5 bar).
Provide adequate ventilation in the environment for a safe operation of
the cooker hood.
Follow the local laws applicable for external air evacuation.

2) Create an opening in the underneath of the kitchen unit; the cut-out must
be of the dimensions shown in the “Specifications of your cooker hood”
3) Make a hole in the inside of
the kitchen unit for the electrical
cable to feed through. Remove
the 2 screws securing the
extractor frame (B) to the hood
and unscrew the 2 lights. Ensure
that the two support clips on
either side of the hood are set to
accommodate the thickness of
the mounting surface, by
adjusting the clip via the screw.
4) Lift the cooker hood towards
the cut-out that you made in step
2. Feed the electrical cable
through the hole that you made
in step 3.
IMPORTANT: Do not connect
the electrical cable to the mains
supply at this stage.
5) Lift the cooker hood fully into the cut out that you made in step 2. If you
are connecting the cooker hood to external ducting, then secure the ducting
hose to the coupling on the appliance.
oOne person should support the hood. The other person should fully
tighten the support screws through the pre-drilled holes in the outer
frame of the hood, into the kitchen unit. Then replace the extractor
frame using the 2 screws (B) and reattach the 2 lights.

7. Maintenance
Before cleaning, switch the unit off and pull out the plug.
I. Regular Cleaning
Use a soft cloth moistened with hand-warm mildly soapy water or household
cleaning detergent. Never use metal pads, chemical, abrasive material or stiff
brush to clean the unit.
II. Monthly Cleaning for filter
ESSENTIAL: Clean the filter every month can prevent any risk of fire.
The filter collects grease, smoke and dust…... so the filter is directly affecting
the efficiency of the cooker hood. If not cleaned, the grease residue (potential
flammable) will saturate on the filter. Clean it with household cleaning
detergent.
