ƽDo not try to use the cooker hood
without the grease filters or if the filters
are excessively greasy!
ƽDo not install above a cooker with a
high level grill.
ƽDo not leave frying pans unattended
during use because overheated fats or
oils might catch fire.
ƽNever leave naked flames under the
cooker hood.
ƽIf the cooker hood is damaged, do not
attempt to use.
ƽDo not flambé under the cooker hood.
ƽCAUTION: Accessible parts may
become hot when used with cooking
appliances.
ƽThe minimum distance between the
supporting surface for the cooking
vessels on the hob and the lowest part
of the cooker hood. (When the cooker
hood is located above a gas appliance,
this distance shall be at least 65 cm)
ƽThe air must not be discharged into a
flue that is used for exhausting fumes
from appliances burning gas or other
fuels. Range hoods and other cooking
fume extractors may adversely affect
the safe operation of appliances
burning gas or other fuels (including
those in other rooms) due to back flow
of combustion gases. These gases
can potentially result in carbon
monoxide poisoning. After installation
of a range hood or other cooking fume
extractor, the operation of open flued
gas appliances should be tested by a
competent person to ensure that back
flow of combustion gases does not
occur.

If the cooker hood does not have an assembled V-flap 1, you should mount the half-
parts to its body.The images only show an example of how to mount the V-flap,
because the outlet may vary according to different models and configurations.
To mount the V-flap 1 you should:
• Mount two half-parts 2 into the body 6;
• the pin 3 should be top oriented;
• the axis 4 should be inserted into the holes 5 on the body;
• repeat all the operations for the 2nd half-part.

If you have an outlet to the outside, your cooker hood can be connected as below
picture by means of an extraction duct (enamel, aluminum, flexible pipe or non-
flammable material with an interior diameter of 150mm)

1. Before installation, turn the unit off and unplug it from the outlet.
2. The cooker hood should be placed at a distance of 65~75cm above the cooking
surface for best effect. See pic 1.
3. Install the hook on a suitable place once the installation height is fixed, and keep it
in line. The fixed position of the inside chimney bracket is the place of chimney.
See pic 2.
4. Fix the outside chimney bracket on the outside chimney, and be sure that the
inside chimney can be adjusted the height in it freely as well as fixing the
expansion pipe. Afterwards, install the expansion pipe and chimney on the cooker
hood.Fix the expansion pipe with a cable tie on the outlet. See pic 3 & pic 4.
5. Put the cooker hood on the hook. See pic 5.

6. Adjust the height of the inside chimney to the position of the inside chimney bracket
and fix it by screws, after adjusting the position, fix the body with safety screws.
Note: The two safety vents are positioned on the back housing, with a diameter of
6mm. See pic 6 & pic 7.

The following rules must be strictly followed to obtain optimal air extraction:
• Keep expansion pipe short and straight.
• Do not reduce the size or restrict the expansion pipe.
• When using the expansion pipe always install the pipe pulled taut to minimize
pressure loss.
• Failure to observe these basic instructions will reduce the performance and increase
noise levels of the cooker hood.
• Any installation work must be carried out by a qualified electrician or competent
person.
•Do not connect the ducting system of the hood to any existing ventilation system
which is being used for any other appliance ,such as warmer tube, gas tube , hot wind
tube.
•The angle of the bend of the expansion pipe should not be less than 120º; you must
direct the pipe horizontally, or, alternatively, the pipe should go up from the initial point
and should be led to an outer wall.
•After the installation ,make sure that the cooker hood is level to avoid grease
collection at on end.
•Ensure the expansion pipe selected for installation complies with relevant standards
and is fire retardant.
