4.7 Before Installing and Removing PR-23-SD Sensor
WARNING: Always use the Safe-Drive™ Retractor tool for inserting and removing the
sensor. Removing the sensor without the Retractor tool may cause a life-threatening
situation, if there is any pressure in the process pipe. Inserting or removing sensor without
Retractor tool may also cause damage to the lip seal. Always store the Retractor tool indoors
in a clean and dry location.
Successful sensor insertion and removal can only be guaranteed when the Retractor tool is
used and the instructions for insertion or removal are carefully followed.
NOTE: Check the Retractor tool visually before starting installation / removal process. Make
sure the handwheel rotates freely.
WARNING: If you detect leaking at any point of sensor installation or removal process,
revert immediately to the previous step in the process. Do not continue installation / removal
until the reason for leakage has been cleared and fixed.
Install and remove the sensor as instructed in the following chapters. For more thorough
instructions, please refer to K-Patents user documentation or visit the K-Patents website to
see the instructional video on inserting and removing the sensor (www.kpatents.com, PR-23-
SD Safe-Drive™ Operation Guide Video).
4.8 Installing Sensor
Before you start
● check that the gaskets and gasket surfaces are clean
and undamaged
● remove the sensor cable gland and unlock Inner casing
1. Insert the sensor to Inner casing so that the inner casing
latch is slightly to the left of top and sensor cable passage
is straight down.
2. When sensor flange is flush with the bottom of Inner
casing, turn Inner casing 1/6 turn clockwise to lock it to
the flange.
3. Push down the locking latch.
Put the Safe-Drive™ Retractor with sensor onto a table or
similar surface so that the hand wheel has space to turn.
1. Fit Outer casing over Inner casing so that the groove on
Inner casing matches the dot on Outer casing.
2. Turn the hand-wheel clockwise until it stops to draw the
sensor into the Retractor.
