REMOVE OLD DOLOG SENSOR
Before old DOLOG is removed please prepare DOLOG sensor cable to be removed.
• Cable end unscrewed fom terminal box.
• A long rope fastened to cable end. This rope will be used for pulling up the new DL850
sensor cable later.
Unscrew the 4 screws with a 8mm Allen key.
There are 2 levels of threads.
• Threads in tank
• Threads in sensor
Do only unscrew the tank threads so the screw hang in sensor as described in below picture
The sensor is now loose but most probably stuck. To force the sensor out of tank use the
removal tool or similar. When loosened, disconnect cable plug.
Use a crow foot 36 mm, 1/2 inch extension and rachet to unscrew 36 mm nut inside tank.
Store the 36mm nut and gaskets in a safe place for reuse on SKIPPER sensor.
Pull out cable and bring cable with rope to a dry place. The rope is now going all the way
from top of tank pipe, through pipe and tank and to the dry place.
