IV MAINTENANCE
PREVENTIVE MAINTENANCE
Preventive maintenance should be done in daily,
weekly, monthly and yearly intervals as necessary.
Following preventive maintenance procedures will help
keep your Pasta System working efficiently. Proper care
and servicing will lead to years of quality performance.
NOTE: The most important part of any maintenance
program is daily cleaning. Ninety percent of any
maintenance problem is directly or indirectly related to
cleanliness.
NOTE: Water level problems caused by the sensors
not being cleaned adequately will not be covered under
warranty.
NOTE: Use of sodium chloride during the cooking
process will have a detrimental effect on the cooker
vessel and will void the warranty.
* High production facilities should be checked more often.
WHEN THE WATER LEVEL FALLS BELOW THE
BOTTOM WATER SENSOR THE HEATING
ELEMENTS WILL TURN OFF. IF THEY CONTINUE
TO HEAT, TURN THE MAIN POWER SWITCH OFF
AND CHECK AUTO-FILL SYSTEM.
LIMITED CALIBRATION
Calibration is not covered under warranty
A. Calibration
NOTE: This procedure can only be used with the
primary (left side) thermostat. When calibrating the
secondary (right side) thermostat you will need:
• One standard flat blade screwdriver.
• One accurate thermometer suitable for boiling water.
NOTE: For best results, water should be clean.
1. Set thermostat to 212°F(190°C).
2. Allow Pasta System to cycle three times.
3. Place an accurate thermometer in the water.
Figure 4-1: Thermometer in water
NOTE: Locate thermometer in same position for
every calibration. Position near primary thermostat
(center) bulb is recommended.
4. If calibration of thermostat is found to be less than
15°F(9.44°C) off, simply loosen three dial plate
retaining screws, rotate dial plate to match
thermometer reading and tighten screws. If the
thermostat is more than 15°F(9.44°C) off then a
qualified service company must be contacted to
have the Pasta System properly calibrated.
