  • Page 18 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.
  • Page 19 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.
  • Page 20 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.
  • Page 21 3.1.3. Using the valve The two operating modes described above are used in the different cooking modes as follows: Convection cooking: the user can establish the closing time % of the vent valve according to the following diagram. 0% - vent always open (red bar on the display) from 10 to 90% - the valve opens and closes in a timed manner, the value shown on...
  • Page 22 3.2. Water System Components The ACTO system includes the following main components: Collection and condensation tank. It is a steel tank placed under the cooking chamber and connected to the chamber drain. It is used to collect the washing fluid. Whereas, during cooking, it collects the condensation coming out of the cooking chamber and also partially condenses the steam coming out of the chamber.
  • Page 23 Steam vent and air intake pipe. Chamber steam vent and intake pipe. The hole is located behind the fan. Drain probe. PT1000 probe, which controls the temperature at the drain and the water supply to the drain. Strainer (Grill). Strainer in the chamber to prevent food residue from falling into the drain.
  • Page 24 3.2.1. Collection and condensation tank The tank is made of stainless steel, sealed welded. The connection to the cooking chamber is made by means of a bush with two silicone ORs. If necessary, by loosening the two support brackets on the bottom of the oven, it is possible to lower the tank so as to uncover one of the two ORs for its replacement (the top one).
  • Page 25 3.2.2. Siphon The siphon is made of two pieces (body and cover) made of nylon reinforced with glass balls and silicone sealed. The siphon is equipped with a safety overflow that discharges directly to the outside (under the oven) in case of clogged drain or reflux from the pipes. A PT1000 probe is inserted in the siphon that measures the temperature of the drain water.
  • Page 26 3.2.3. Water inlet unit components The two water inlet units (steam and washing/drain) are constructively equal and consist - Water inlet with built-in filter - Water solenoid valve - Flow meter - Calibrated dispenser Inlet with built-in filter Calibrated dispenser Flow meter Solenoid valve The flow meter provides a number of pulses to the board, proportional to the amount of...
  • Page 27 If, after a few seconds from opening of the valve, the flow meter has not yet counted any pulse, a no water alarm is given. If, when a certain time expires (timeout), the flow meter has not yet reached the preset pulse value, an alarm is given due to water flow rate too low.
  • Page 28 3.2.4. Drain cooling operation The washing/drain water inlet unit has only one outlet connected to a fitting located in the vertical vent pipe. During cooking, this fitting injects water into the vent pipe to condensate the outlet steam, to keep the siphon filled and to maintain the temperature of the drain water within certain limits.

  • Page 70 5. OPERATION, TESTING, ADJUSTMENT, INSTALLATION REPORT, GAS CIRCUIT ALARMS 5.1. System operation 5.1.1. General principles of the pre-mixed system The ACT.O oven gas system is of “total premixing” type, meaning that the gas is totally mixed with the air required for “good” combustion and then the air-gas mixture is ignited at the burner.
  • Page 71 5.1.2. Power schemes As is evident from the previous diagram, air and gas in the premixed system are drawn and simultaneously mixed by a fan. It is, therefore, possible, by electronically controlling the fan rotation speed, to draw more or less mixture in order to obtain a variation of the gas flow rate and so of the burner power.
  • Page 72 Copyright by Servizio Clienti ANGELO PO Spa...
  • Page 73 5.1.3. General functional diagram The diagram shows how the main components interface with each other. The panel board feeds and drives the combustion control board, which during ignition then controls the blower, the gas valve and the igniter, until it receives the flame detection signal. Similarly, during shutdown, it simultaneously controls the valve closure and the blower switch-off.
  • Page 74 5.2. System components The following diagram shows the system components. Important: always check before every intervention that all components are securely fixed (electrical connectors, screws, clamps, fittings, insulating material) make sure that the air inlet filter (9) and the fitting on the foot-holder of the valve pressure socket pipe (6) are completely clean (if necessary, use a toothpick or rag to remove built-up dirt).

The value read is to be divided by 10 The maximum value displayed is 19μA (actual reading greater than/equal to 1,9μA).

  • Page 114 6. WASHING OPERATION 6.1. Introduction The washing system is of the “recirculation” type. This provides for the washing fluid (water + chemical) to be collected into a tank placed under the cooking chamber and continuously recirculated through a pump. The standard washing system requires for the user to manually load the detergent/descaler inside the cooking chamber.
