Digital Controller Sensor Installation; In Thermostat Housing Method - Davies Craig EWP-FAN Installation Instructions Manual

Remove the engine thermostat from the thermostat housing and install the sensor using method A or B as
shown below. Re-fit the thermostat housing without the thermostat and ensuring that there is no damage to the
thermostat-housing gasket.

DIGITAL CONTROLLER SENSOR INSTALLATION

There are two installation methods available:
A) IN THERMOSTAT HOUSING METHOD
Please ensure these instructions are read in their entirety before proceeding with installation.
 It is recommended that the Sensor assembly be installed in the thermostat housing (not supplied).
However, please check wall thickness of thermostat housing as it is recommended that the Sensor
assembly be installed only if there is a wall thickness of at least 3.0mm. If the thickness is less than 3mm,
please proceed with installation method „B‟
 We suggest removal of the thermostat housing before beginning the installation process so that metal
shavings do not enter the cooling system.
STEP 1: Mark location on thermostat
housing where sensor assembly is to be
fitted – "top of dome is recommended".
¼" BSPT TAP
(not supplied)
STEP 3: Using a ¼" BSPT tap, tap the hole to allow the sensor
assembly to "just" protrude the thickness of the thermostat housing
(refer to diagram). It is recommended that the fitment of the sensor
assembly be checked regularly to achieve the condition in the
diagram.

STEP 2: Drill an 11.0mm (7/16") hole
through the marked area. For your safety and
to avoid drilling on an angle, please ensure
thermostat housing is well secured before
beginning the drilling process.
