5. WASHING CYCLES LEVELS 3
5.1. Washing circuit operating and components
The washing circuit consists of the following components:
• Non-return valve (in the water inlet assembly) prevents the contamination of the water
mains. If there is a decompression in the water supply network the valve drains the fluid
outside of the circuit downstream of itself, preventing a possible flow back into the water
network.
• Pressure adjustment (in the water inlet assembly).
• Water solenoid valve (in the water inlet assembly).
• Detergent dispenser (pump unit): peristaltic pump type.
• Sanitizer dispenser (pump unit): same as previous.
• Mixing tank.
• Drain solenoid valve (pump unit): normally close valve. It drains the contents of the tank
into the pipe connected to the siphon.
• Fixed sprinkler into the cooking chamber: 8 nozzles sprinkler.
• Fixed sprinkler closed to the heat exchanger: it is near to the pipe for the steam
production. Through this pipe the chemical reaches the nebulizer cleaning in the heat
exchanger compartment.
