SAFETY FIRST
ADT believes that the safety of personnel working with and around our
systems is the most important consideration. Read the safety information
before operating the System or perform any maintenance function.
Warnings
Obey and follow all warnings and cautions given in this manual.
Comply with all approved and established precautions for operating
electrical equipment.
Only qualified and authorized personnel should perform maintenance
or repair tasks.
Verify the power, air and water facilities are turned off before
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
following safety features. Look at them and get to know them.
EMERGENCY STOP BUTTON: Pressing the red EMERGENCY STOP BUTTON
stops ALL activities in the System. The Emergency Stop Button is
located on the system front panel.
CIRCUIT BREAKER SWITCH: switching down the CIRCUIT BREAKER SWITCH
immediately cuts off power to the System. The Circuit Breaker Switch
is located on the system right side.
FRONT LOWER COVER SAFETY SWITCH: when opening the Front Lower
Cover, the FRONT LOWER COVER SAFETY SWITCH puts the system in a
Standby mode. The Front Lower Cover Safety Switch is located behind
the lower front door, on the upper left corner.
COVERS LOCK: all of the system COVERS (except the front main door)
require a metric Allen wrench for opening and removing the cover.

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.

4. PREPARING THE SYSTEM
The 927 Water Recycling System is used for recycling the dicing saw
cutting water. Therefore, preparing the System requires connecting the
927 System to a dicing saw.
Preparing and setting the system includes the following actions:
Inspecting the valves orientation (section 4.1)
Filling the water tank with fresh water (section 4.2)
Bleeding air from the pumps (section 4.3)
Checking to ensure there are no water leaks (section 4.4)
Placing the System (section Error! Reference source not found.)
4.1 Inspecting Valves Orientation
Before operating the System, verify the manual (orange) valves are in the
required orientation.
Remove the upper and lower front covers on both sides of the System.
Verify the valves are oriented as follows:
Pump 1(P1):
In: open
Out: open
Pump 2(P2):
In: open
Out: open
Pump 3(P3):
In: open
Out: open
Filter 1(F1) (pre-filter):
In: open
Out: open
Manual drain: closed
Filter 2(F2) (slurry bag-filter):
In: open
To sink tank: open
To external drain: closed

4.2 Filling the Bottom Water Tank
Open the valve for the Water Fill. The bottom tank starts filling, until the
water level reaches the second level-sensor.
4.3 Bleeding Air from Pumps
The pumps have trapped air which needs to be removed from the pump.
This is done by operating the system and opening the bleed screw until
the air is removed.
Caution: Thebleeding air from pumps procedure may cause some water spillage.
Place cloths or other absorbent material under the pump to absorb the water.
To bleed air from the pumps:
Power on the System.
Open the bleed screw of pump P1, just until water start coming out.
Figure 4-1. Pump air bleed screw
Close and tighten the screw.
Repeat the air bleeding procedure for supply pump P3.
4.4 Checking for Water Leaks
Press the Run button, and visually inspect to ensure there are no water
leaks. Carefully inspect all pipe connections and valves.
4.5 Operating parameters
After preventing maintenance procedure is finished and machine is setup
and running, make sure that the following parameters values are in the
correct range:
Filtration flow rate = 25 LPM (Liter per minute)
Filtration pressure = 0.81.3 Bar
Supply flow rate = 520 LPM
Backwash flow rate = 25 (or above) LPM
