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 17

Preparing the System Options 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: The bleeding 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: 3. 4. 5. Power on the System. Press the PLC numeric key 1 (for 3 seconds) to activate pump P1. Open the bleed screw of pump P1, just until water start coming out. Bleed Screw 6. 7. 8. Figure 4-1. Pump Air Bleed Screw Press the PLC numeric key 1 (3 seconds) to stop the pump operation. Close and tighten the screw. Repeat the air bleeding procedure for pump P2 (numeric key 2) and pump P3 (numeric key 3). 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 Placing the System Close the System covers, and place it at its working location. Then, push down the locking leaver of all 4 wheels.

ADT Model 927 Water Recycling System Preparing the System 4.8 Filter Backwash The returned cutting water flows through the System filters, and the filters begin to accumulate cutting remains and debris. The System automatically performs a backwash process, according to the process setup parameters (see section 4.7), cleaning the double filter modules with clean water from the supply (upper) water tank. The 927 System can be set to flow the filter backwash water through the slurry bag-filter, resulting in 100% of water recycling, as illustrated in the following Figure 4-4. Figure 4-4. Backwash through Slurry Bag-Filter To set the backwash water to flow through the slurry bag-filter: 1. Rotate the orange valve at the exit of the slurry bag-filter (going to the sediment tank) to its open orientation. 2. Rotate the orange valve at the exit of the slurry bag-filter (going to the external drain) to its closed orientation. 23

Preparing the System Options Or, set to flow the double filter module backwash water to an external drain, resulting in 95% of water recycling, as illustrated in the following Figure 4-5. Figure 4-5. Backwash to Drain To set the backwash water to flow to the drain: 1. Verify the drain tube is connected to the Drain outlet of the 927 System (see Figure 3-8). 2. Insert its drain tube to the facility drain. 3. Rotate the orange valve at the exit of the slurry bag-filter (going to the sediment tank) to its closed orientation. 4. Rotate the orange valve at the exit of the slurry bag-filter (going to the external drain) to its open orientation. Advanced Dicing Technologies Ltd. 24

ADT Model 927 Water Recycling System Operation 5. OPERATION The operation chapter explains how to use the Model 927 for continuously supplying clean water to the connected dicing saw(s). Note: Before using the 927 as the dicing saw cutting water supply, follow chapter 4 for preparing the system, and ensure the front lower door is closed. To operate the 927 System: 1. 2. Power on the system. The system goes through an initialization process. Press the Run button. The water pumps start operating, and the PLC displays the first main screen, showing the : Filter water flowrate [L/m] Supply water flowrate [L/m] Water starts circulating, as illustrated in the following Figure 5-1. Figure 5-1. Water Flow Illustration (service mode) 5.1 Service Process Flow 1. Water is pumped (P1) from the sediment (bottom) tank, through the pre-filter and the double filter modules, to the supply (top) water tank. 2. Water is pumped (P3) to the dicing saw. 3. The dicing saw drain water flows to the sediment tank. Note: Fill water fills the sediment (bottom) water tank to ensure its level is at level sensor 2 (see Figure 8-5 in Appendix B). 25

Operation Options 5.2 Backwash Process The backwash process automatically cleans the double filter modules, based on the process setup values (see section 4.7.2). During the backwash process, clean water, from the supply (upper) water tank, flows through each of the filter modules from there top to bottom. The backwash process does not interfere with the System operation of delivering cutting water to the dicing saw. The dirty water then flows either to the external drain, or through the slurry bag-filter to the sediment (lower) water tank. Depending on the System setup (see section 4.8). 5.2.1 Manually Activating the Backwash Process The backwash process can be manually activated by pressing keypad 2 on the main controller (PLC). However, the condition is that the supply (top) water tank mid-level sensor is up. If the Backwash FF value is set to Yes, pump P1 needs to be operating. If the Backwash FF value is set to No, the state of pump P1 does not matter. Advanced Dicing Technologies Ltd. 26
