1.4. Water characteristics
The equipment must be supplied with drinking water featuring the specifications stated in
the table. If these characteristics are not respected, the equipment may be damaged,
therefore, the use of a water treatment device is recommended.
Note: the machine warranty will become void if the requested value are not met

2. OVEN INSTALLATION
2.1. General installation notes
- Noise: the ovens are below 70dBA as per the Machinery Directive.
- Position the OVEN respecting the distances required as in tab.1. If they are not
respected and equipment is installed on the left side of the OVEN that can
produce/emit steam and/or heat, provide for the installation of the Anti-Heat Screen
accessory.
tab.1
- Check the water characteristics (chapter 1.4) and recommend suitable treatment.
- Connect the oven to cold water.
- Check adequate dynamic pressure and water flow rate (see “Water
characteristics”).
- Connect the water drain. The mains pipe (A) must have a minimum diameter of
40Ø, a minimum tilt of 5% and a maximum length of 1.5 m.
- Check unit levelling and stability.
- Check for potential issues arising from damp environments.

- All ovens are supplied and tested ONLY for G20 gas (the other nozzles for gas
transformation are supplied)
- Check the type of gas supplied
- If the gas supplied is different from G20 (Natural Gas) it is necessary to change the
gas nozzle and insert the one corresponding to the gas type.
- Check the dynamic supply pressure of the GAS

- During installation, the connection between PHASE and NEUTRAL must be
respected, i.e. the polarities must not be reversed. Incorrect connection causes a
lower reading of the ion signal detected by the spark igniter in microampere (µA).
- Proceed with the fumes analysis.

3. FUNCTIONAL DIAGRAM OF THE OVEN
3.1. Chamber steam vent pipe operation
The principle of operation of the steam control system in the ACTO oven is direct injection,
i.e. there is no boiler and the water is sent directly to the centre of the fan. The steam vent
pipe is connected to the collection and condensation tank under the chamber. During
cooking, the steam comes out of the cooking chamber drain, passes through the collection
and condensation tank and then comes out through the vertical vent pipe.
This vertical vent pipe is equipped with a butterfly valve that, when needed, closes, but not
sealed, the vent itself.

The system works in two different ways depending on whether the motorized valve is open
or closed.
3.1.1. Open valve operation
The fan rotation generates a local vacuum effect in the area behind its rear disc where
intake/exhaust pipe 1 is engaged. When butterfly valve 2 is open, this vacuum effect sucks
an inlet air flow through pipe 1. At the same time, the humid air inside the cooking
chamber is induced to come out through vent pipe 3, passing from drain valve 7 (always
open) and from collection tank 5 placed under the chamber. Water is sprayed through
fitting 4 into the vent pipe –especially at high temperature –in order to cool and condense
the outlet humid air flow. The condensate is collected on the bottom of the pipe and
conveyed to siphon 6.
OPEN VALVE

3.1.2. Closed valve operation
In the closed motorized valve (2) operation, the steam cannot escape from vent pipe 3 or
from pipe 1, at least until the pressure inside the cooking chamber is such to overcome the
vacuum effect generated by the rotation of the fan (normally 1,5-2,0mbar). Whereas, when
the pressure in the chamber exceeds the vacuum generated by the fan, the excess steam
is expelled through pipe 1. In this way the system works like a closed system, where the
overpressure is created by the dynamic vacuum effect generated by the fan. In this mode
also cooling water is sprayed from fitting 4 in order to keep siphon 6 full.
CLOSED VALVE
