2.1  CONTROL UNIT MOUNTING 
The Control Unit 1-53836-K270 (1-53836-K270-01 Caterpillar only) or 1-53836-K276 is designed for on-
engine mounting and it is recommended that the Control Unit is installed as near to the centre of the 
engine as possible to minimise detector cable lengths. 
Mounting is via the four M6 locating holes in the box. Enough space must be left around the Control Unit 
to allow access to the cable glands and the routing of the cables and to facilitate easy access to all 
aspects of the Control Unit.
