tion 2.1
Important: These instructions are for Safe-Drive™ generation 2.1. If you have Gen-

Warning!
Always use the Safe-Drive™ Retractor for sensor insertion and re-
moval!
Safe sensor insertion and removal can only be guaranteed when the Retractor
tool is used and these instructions are carefully followed. Removing the sensor with-
out the Retractor tool may cause a life-threatening situation if there's any pressure in
the pipe. Also, the lip seal damages easily if Retractor is not used.
Important: Safe-Drive™ is designed to protect user from process liquid and to safely
insert and remove the sensor. However, do not underestimate or neglect the factory
safety requirements:
• Wear long-sleeved safety clothing since the process liquid can be ei-
ther hot, corrosive or both
• Use protective gloves
• Use safety glasses and/or goggles
• Use ear protectors
• Use a hard hat or helmet
• Use face visor
• Wear hard-cap safety boots
• Before you start, locate the nearest emergency shower and eye wash
• Never operate the system alone: It is recommended for one operator
to read the instructions and guide the second operator performing
the step
Warning! The drain valves (see Figures 11.10 and 11.13) should always be closed
unless otherwise indicated. If the valves are left open, process liquid will leak out
through them.
