Ventilation
Adequate ventilation is essential for correct operation and durability of the generator set.
The generator set room must:
• Allow the heat produced by operation of the generator to be dissipated by radiation and convection.
• Provide sufficient air flow for engine combustion and cooling.
• Provide adequate air for the health and safety of the operator.
Heating
To ensure quick starting of automatic starting generator sets, the engine room temperature must be maintained
above 10–15°C (50.0–59.0°F).
Electric heaters with thermostatic controls ranging from 500W to 1,500W are available for cold climates.
Where necessary, battery chargers and heaters should be connected to a voltage supply.
Fuel Supply System
The generator set is supplied with an integral fuel supply system with a fuel tank located on the bed plate.
The fuel tank is connected to the engine by flexible pipework suitable for normal operating conditions.
In especially arduous conditions a separate fuel tank may be required. This must be connected to the engine
using suitable pipework to ensure that the fuel injection pump can draw fuel correctly.
Electrical Connections
The generator set cables must be correctly connected as shown on the electrical schematics.
Grounding
Metal parts that may be exposed to human contact must be connected to ground.
Suitable protective conductor connections should be made in accordance with local regulations.
Operating Generators in Extreme Cold Climates
When the JCB Generator is operated in extreme cold climates, care must be taken to prevent the operating
temperature of the engine decreasing below a level that will result in the incorrect operation of the engine
components. Additional care must be taken to prevent the engine components from freezing or failing to
operate.
