beginning any maintenance procedure, part replacement, or repairs.
Danger: Electrical Shock Hazard. High voltage ispresent at points throughout the
System. Contact with high voltagecan result in injury or death. Before openinganycover,
make sure that there is no voltagepresent byswitching off the Circuit Breaker. Switching off
the Main Power Switch does not cut off power to the system.When performing maintenance,
disconnect the mainspower plug from the wall outlet.
Danger: High PressureWater and Air Hazards.Observe standard operating
procedures toavoid contact with High Pressure Air andWater, whichcan present hazards,
especiallyto eyes.
Danger: Bodily Injury Hazard. Becareful not to drop anyof the system parts. Dropping
certainparts mightcause bodily injuryor damage to the parts.
Safety Features
The ADT Model 927 Water Recycling System is equipped with the

1. OVERVIEW
The ADT Model 927 Water Recycling System provides a closed-loop
uniform supply of water, which is used for dicing machines.
The system recycles the saw drain water through a number of filters, cools
the water to a set temperature, and delivers a steady flow of water to the
dicing machine.
The 927 preventing maintenance procedure is recommended to be
performed every 6 months under regular conditions. The preventing
maintenance procedure is done in addition to the maintenance tasks that
are performed routinely on a periodic basis, and maintenance performed
because of warnings displayed by the PLC. For further information regard
routinely maintenance, see 927 full operation and maintenance manual at
section 6.

3. PREVENTING MAINTENANCE PROCEDURE
Caution: Cleaning and replacing the water filters may cause water to spill on the
system and on the floor. Place cloths or other absorbent material under the
cleaned/replaced filter to absorb the water.
Note: Cleaning and replacing the filters requires putting the system in standby
mode or powering down.
3.1 Water tanks cleaning
After working with the System for a long period, dicing debris
accumulates in the sediment water tank.
To empty the water tank:
Power down the System.
Remove the rear lower cover.
Put a bucket or a vacuum cleaner near the sediment water tank cork,
and open the cork.
Do the same for the supply water tank.
Use a piece of cleaning cloth or cleaning paper towel to remove all
sediments of sediment water tank. Clean the inside of the tank. In
addition clean the water level sensors.
Do the same for supply water tank.
