The DI water system requires periodic filling or “Top-Off” to replace tiny amounts of DI water lost during the cutting cycle. Should the system run low on water during operation, the Hand Tool will indicate a flashing red light and the display will indicate a “Low Water Level” condition. To “Top-off”, fill an open container with approximately 1 gallon of clean water, enter the maintenance Screen, touch the Top-Off function, and immerse the Adapter of the E-Drill in a vessel of water (do not submerge the entire drill, only the front of the E-Drill Adapter should be submerged).
Note: If using a hand-tool with 30’ umbilical cable, a faster technique is to disconnect the Hand Tool fluid tubes at the back of the MSU and use the service tubing to fill; filling through the Hand Tool may take a long time.
CAUTION
Submersing the E-Drill, its mechanism, or any parts other than the Adapter will destroy the E-Drill electronics and void the system warranty. Submerging the E- Drill fully in water may also cause operator injury due to electrical shock.
When the Tank is full the Full LED indicator will illuminate green, and the pump will turn off automatically. The system is then ready for continued use.
Note: The Top-Off pump may be stopped manually by pressing the Top-Off button a second time. Exiting the Maintenance Screen will also automatically turn the Top-Off function off. However, a “Low Water level” condition can only be cleared by completely filling the system, stopping the fill process manually or exiting Maintenance Screen will not clear the error.
The Top-Off function will not work if the tank is already full.
