The Rev 01 of KIT-DOLOG-M1-SA is a plastic adaptor.
The sensor replacement is recommended to be performed in dry dock. It is possible to
replace the sensor with vessel aoat.
The replacement will require new DL2 Operator unit, transceiver unit, junction box and
sensor. For DL2 Operator unit and Transceiver unit installation instruction, please see DL2
installation manual.
This procedure will mainly cover replacement of DOLOG sensor.

The sensor cable pipe (orice tube) on the housing is part of the ship hull and has to reach
above waterline (CWL=Construction water line.)
If sensor is replaced by diver in water this construction will enable water to come into the
oricife tube construction but will stop at the level of water line.
The pipe has a watertight gasket in both ends.

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.

PREPARE SENSOR FOR INSTALLATION
Install the 36 mm nut and gasket onto the 40 m cable of new DL2SDR-SA sensor.
NOTE If installed by diver with vessel aoat:
The sensor cable is now going to be lowered into salt water.
To avoid salt water to penetrate into cable during diving operation the cable end is sealed.
Fasten the rope to new DL2SDR-SA sensor cable end.
The new sensor cable may now be pulled up the tank pipe. Fasten gasket and 36 mm nut.

INSTALL SENSOR INTO DOLOG TANK
Lift the sensor into the dolog tank Fsten with 4 x screw M10x80.
The 2 x threaded bolts M10x400 and wing nuts included in the KIT-DOLOG-T1-SA kit may
be used to lift the sensor into the dolog tank.
Raise the complete sensor with help of the 2 x wing nuts. When in upper position fasten the
2 x M10x80 mm screws.
When sensor is raised and secured with 2 x Screws M10 x 80 mm.
Remove the 2 x 400 mm threaded bolts. Fasten the next 2 x M10x80 mm screws were
threaded bolts are removed.
