B.The Water Auto-Fill and Low Water Safety Shut- Off Systems

The water supply connection, located at the bottom rear of the Pasta System and marked water, is a standard 3/8” female pipe connection. The water pressure should be between 20-60 psi. If the pressure exceeds 60 psi, a pressure regulator must be used. The water temperature must not exceed 150°F(65.6°C). Hot or warm water is not needed due to the instant recovery of the Pasta System.

Connections suitable for hot water must be used. All connections must be tested for leaks before using the Pasta System.

￿NOTE: For Pasta Systems with casters, flexible hose must be used to avoid leaking when the Pasta System is moved for cleaning.

Control of the water level is fully automatic with the auto-fill system. The water level is controlled by two circuit boards and two sensors. The sensors are located in the tube on the right side of the overflow deck. The upper sensor controls the water level and the lower sensor controls the low water safety shut-off system. Once the water On/Off switch is turned on, the blue light will come on and start to fill until the water level reaches the upper sensor. The burners will not come on until the water level reaches the lower sensor, preventing the Pasta System from being damaged if there is little or no water in it. Both sensors must be cleaned with the sensor brush (like the one provided) on an hourly basis or whenever starch foams up to maintain the proper water level. Sensors must be cleaned more often in areas with hard water, in installations with softened water (due to the salt in the water) or when oil or salt is placed in the water for cooking.

The brush must be checked on a regular basis and replaced whenever it starts to wear.

Do not store the sensor brush in the sensor tube as it could contact the sensors, which could allow the water level to drop below the heat tubes and damage the Pasta System.

Using a worn brush could damage the sensors.

￿NOTE: Water level problems caused by the sensors not being cleaned adequately will not be covered under warranty.

WHEN THE WATER LEVEL FALLS BELOW THE LOWER SENSOR THE BURNERS WILL SHUT OFF. IF THEY STAY ON, TURN THE MAIN POWER ON/OFF SWITCH TO THE “OFF” POSITION AND

CLEAN THE SENSORS THOROUGHLY. IF THE PROBLEM STILL OCCURS, HAVE THE WATER AUTO-FILL SYSTEM CHECKED BY A QUALIFIED SERVICE TECHNICIAN.
