Operating Manual Installation of the System for Measurement 3.10 Filling with Water Please refer also to the instructions in the SCANLIFT user manual. 3.10.1 Initial Filling of the System CAUTION Improper handling. Equipment damage! Before you fill the Perspex tank, make sure that the water and the Perspex tank are at room temperature and the water hose is connected. NOTE Use only distilled water to fill the system. Add an anti-corrosion fluid recommended by PTW-Freiburg (PTW-Nr. L999010) to one filling. Follow the instructions of the manufacturer for the dosage of the anti-corrosion fluid. The anti-corrosion fluid has no effect on the absorption and scatter characteristics of highenergy radiation. PTW recommends the following procedure for initial filling of the system: Fill the Perspex tank up to the top horizontal mark with distilled water from a canister or a supply line. Then let the water flow into the SCANLIFT water reservoir: To start the emptying process briefly press once the WATER key on the SCANLIFT control pendant. To stop the emptying process press the STOP key. 3.10.2 Pumping Process CAUTION Improper handling. Equipment damage! Damage to building! Watch all pumping processes so that you can switch off the pump as soon as the Perspex tank has been completely filled or drained. When filling the Perspex tank the default setting for pumping at SCANLIFT of 4 minutes is too long and the Perspex tank would run over. Thus filling has to be done imperatively under visual inspection and the pump has to be stopped in time by pressing the STOP key. CAUTION Improper handling. Equipment damage! Make sure that the SCANLIFT pump never runs dry. If the pump runs dry, stop it immediately. Add additional water to the SCANLIFT water reservoir if necessary.
