7 - Operating instructions
7.1 CHS hood start-up
Each operator before starting work on the machine must have read this instruction manual and be aware of
all the warnings contained herein.
Connect the steam exhaust [1] of the oven, with the connection hole [7] located on the CHS hood, with a
connection pipe [9]. (Connecting pipe supplied by the installer )
Connect the condensate drainage [2] located in the back side of the hood, to a water discharge or any other
liquid collector for condensation drainage. After connecting the power supply, press the power button (see
picture) on the right side of the hood.
On detection of any type of malfunction, stop the machine using the main switch and request assistance
from the maintenance person.
7.2 Operating principle
The CHS version of the hood is designed to break down the vapors and odors from the baking chambers
through the action of the extractor [8].
Steam condensation occurs through the passage of the air into a "refrigerant exchanger" or tube evaporator
[5], powered by the condensing unit [3], where the humidity condenses by cooling.
Odor break down is carried out by conveying the passage of air through a filter of activate charcoal [4],
which is capable of retaining volatile organic substances, such as odors and fats. The purified air is then
expelled from the extractor [8].
For proper operation of the hood, it is advisable to turn it on from 5 to 10 minutes before turning on the
oven on, and turn it off from 5 to 10 minutes after the oven has been switched off. This for the complete
elimination of the exhaust materials produced from the oven.

the area of the metal fins to prevent the ventilation from obstructing. Cleaning of the condenser can
be done with a soft brush or a vacuum cleaner
8.2 Maintenance of carbon filter (CHS)
On the upper part of the hood, near the extractor[8], there is a filter drawer[4] containing the active carbon.
For continued effectiveness of the active carbon filters, it is recommended that you remove the drawer and
rinse with warm water. The rinse operation of the carbons should be carried out every 120 hours,
meanwhile the replacement should be carried out every 3000 hours of hood operation.
When the carbon is exhausted dispose of it in accordance with regulations.
