Inhalation of chemical gases is a health hazard. • Open the container only while the chemical gas is being extracted. • Please observe the applicable threshold limit values. • Wear the necessary personal protective equipment (PPE) (suitable protective clothing, protective gloves, respirator and safety goggles / face shield).
- Page 20 Assembly / commissioning Remove the dispense head, if present, from the system-side docking station. Wet the o-ring (4) with ultra pure water. Wetting with ultra pure water minimizes sliding friction and protects the » o-ring from damage. Make sure that electrically conductive dispense heads are properly grounded with a ground wire and terminal.
- Page 21 Assembly / commissioning Press the code disk into the recess of the dip tube. 10. Before screwing it on, make sure that the dispense head is not set at an angle to avoid tilting and damaging the threads. 11. Screw on the dispense head with the tightening nut (7) using the torque tool (8) (see Section 3.1) with the correct torque.
