EXPLANATION OF COMPONENTS
EXTERNAL POWER SOURCE TYPE ENGINE PREHEATING HEATER
For cold weather (ambient temperature -30°C (-22°F))
This preheater is used as a starting aid when it is difficult to start the engine because of the cold temperature. It is
used even when the ambient temperature is above -20°C (-4°F) in seasons where the temperature goes down to
-20°C (-4°F).
Using an external power source (single phase, AC200 - 240V) to heat up the engine coolant and the oil in the engine
oil pan and power train oil pan will make it easier to start the engine.
PROCEDURE FOR SETTING UP EXTERNAL POWER SOURCE
1.
When using this engine preheating heater, it is necessary to provide the following external power source.
For details, see Step 3.
2.
It is necessary to make locally the cable used to bring the electricity above to the input socket (receptacle)
installed to the machine from the external power source.
For details of the manufacturing procedure, see Section 4.
3.
The external power source input cable is the electric cable to bring the electricity from the local AC power supply
to the input socket on the machine. Connect it as shown in the diagram below to operate the electric heater.
REMARK
The electric leakage breaker is installed to prevent danger of electrocution if the electrical supply leaks to the
machine.
The ground cable is connected to the ground for the same reason.
This is to prevent any drop in voltage.
