DIGITAL THERMATIC FAN SWITCH - PART # 0444
WARNING:
THIS DIGITAL THERMATIC SWITCH IS FOR 12V USAGE ONLY! - Changing the built in 12V relays to 24V relays can be used for 24V applications.
INSTALLATION OF THERMAL SWITCH
1.
The Switch should be mounted in the engine bay, adjacent to the
radiator using the self-tapping screws provided. Please keep unit
away from high heat sources, such as exhaust manifolds etc.
Kit Contents:
Controller x 1 – Mount Kit x 1 – Scotch Lock x 1 – Ring Terminal
(Yellow) x 1 – Self Tap Screw x 2 – Connector (Yellow) x 1
2.
Select the temperature sensor mounting location before installing
the fan (if applicable). Temperature Sensor Probe installation
requires access to both sides of the radiator. Remove the radiator
and/or condenser, if necessary, to allow access to both sides.
3.
For optimum performance, install the Temperature Sensor in the
radiator fin section as close to the hot coolant inlet as possible.
Select a position that will not interfere with the fan. The
Temperature Sensor probe
MUST NOT
extend through the
radiator core as this will affect the Switch’s operation.
* Note:
using a suitable 5mm compression fitting
(Not provided)
you can install the sensor probe in to the top radiator hose.
4.
Remove quick fit mount rod, button and foam pad and then
remove backing paper from foam pad. Slide foam pad onto the
quick mount rod so the pad adheres to the under face of the head
of the quick mount rod.
5.
Gently
separate the radiator fins in area where you propose to
mount/insert the temperature sensor probe, using the quick mount
rod or similar so as not to not damage the tubes. Insert the quick
mount rod through the separated fins along with the Temperature
Sensor probe (as illustrated). Push the locking button and Sensor
onto the quick mount. Align and insert into the separated fins,
pushing locking button onto the quick fit mount to sit flush with
the face of the radiator. Cut off excess quick mount rod.
WIRING DIAGRAMS:
Please refer to the wiring diagram overleaf for
installation of this Thermatic Switch. The wiring diagrams found in the
Davies, Craig range of Thermatic Fan Kits are for use with the Mechanical
Thermal Switch only
.
WARNING
:
Do not use the vehicle’s engine management system or
wiring connected to the management system as an ignition source as
it may cause failure of the management system and/or the electrical
system. The ignition source must be a steady positive supply of 12-
16VDC (for 12V applications).
Note:
To convert temperature
reading from Centigrade to Fahrenheit, simply press the set button
(when it’s in the ambient temp mode) & hold for 5 seconds. Release
the button when it’s changed.
SETTING THE ADJUSTABLE THERMATIC SWITCH
1.
Press the set button once, then it will show the current set
temperature, then begin by holding down the Temperature
Set Button till the LED display reaches the maximum 110°
C then release Temperature Set Button. If the button is not
touched for 5 seconds this set temperature will be stored
and the LED will display the ambient (air) temperature.
2.
Start the engine and allow the engine temperature to rise to
around ¾ on the vehicle’s temp gauge which should be
higher than the normal operating engine temperature. The
operator needs to decide the engine temperature at which
the #1 fan will commence operation.
(Note: the air
temperature around the Sensor positioned in the top of the
radiator fins will be around 15C lower than the engine’s coolant
temp.)
3.
Then, hold down the Temperature Set Button until the
LED reaches the temperature the operator wishes Fan #1 to
start. Once this temperature is reached, lift your finger off
the Temperature Set Button which will automatically
set/target the selected temperature
(after 5 seconds)
that
Fan #1 will start. Fan #2 (if applicable) will start operation
10 seconds after Fan #1 starts.
4.
The fan/s will operate until the air temperature falls by 5 C
below the Targeted/Set temperature.
5.
Conduct a road test, monitoring engine temperature. If necessary,
adjust the set/target temperature to suit your requirements.
6.
NOTE:
Check that the fan(s) face the correct direction. On the
hub of Davies, Craig fans there are a message “This side must
face the front of the vehicle”. Check that the fan(s) rotate in the
correct direction, which is in the direction of the arrow on the
hub. If the fans rotate in the wrong direction swap the two leads
to the fan motor. Engine coolant under system pressure boils at
118C. If you are in any doubt about any of these instructions
consult your retailer or DAVIES, CRAIG direct on +61 (3) 9369-
1234 or
