Construction modifications
In order to be able to combine the extractor hood with
"Lengthwise 6-10 racks 1/1" convection ovens, the
hood has been specially designed for screwing directly
in the holes already existing in the top of the ovens
(see Fig. 1 B).

GENERAL DESCRIPTION OF MACHINE
B1
General description
The equipment is suitable for the extraction of steam
emitted from "Lengthwise 6-10 racks 1/1" ovens, from
the exhaust flue and frontally when opening the oven
door.
When the door is opened, the hood increases the
extraction speed in order to filter as much steam as
possible, gradually decreasing to the initial speed.
If the door is suddenly closed, extraction returns to the
initial speed.
The machine is designed for the above-mentioned
applications. Under no circumstances can the machine
be used for other applications or ways not envisaged in
this manual.
This equipment has been designed to address the
needs of a better working environment and better
economy, and is used in restaurants, canteens, cooking
centres and large institutions.
B2
Description of machine modules
The machine comprises the following zones:
A. Steam extraction zone, in the front of the hood.
B. Electrical power and water filling/drain zone in the
back of the hood.
C. Air purification (grease and odours) zone on the inside
of the hood (not visible to the naked eye).
D. Treated and purified air (odours) outlet zone, on the
top of the hood.
B2.1
Zone A - Front extraction
The steam is sucked in this zone when the oven door
is opened. The presence of labyrinth filters allows
prefiltering, whereas the second filtering phase is
ensured by the filters in Zone D.
There is also the control panel for controlling the
available functions (see sec. "F DESCRIPTION
CONTROL PANEL").
B2.2
Zone B - Connections
The plumbing connections for filling and draining water
and, by removing the rear panel, descaling of the
internal condenser and attaching the hood to the oven
must be carried out in this zone.
There is also the power cable for connection to the
workplace electrical system and the cable for connecting
the oven.
B2.3
Zone C - Filtering zone
Filtering of the oven steam coming from the upper
exhaust occurs in this zone not visible to the naked eye.
The steam passes through the grease condenser,
which eliminates cooking grease thanks to the presence
of cold water (the water is automatically drained
and refilled according to hood use), then through the
catalytic converter which eliminates odours and then to
Zone D where there are more filters.
B2.4
Zone D - Silica gel filters
This zone has the silica gel filters for eliminating the
residual moisture of steam extraction from Zone C and
Zone A.
Together with the silica gel filters there are also air
filtration acrylic cloths.
The silica gel filters can be removed and regenerated.
