AUXILIARY FUEL TANK OPTION

The auxiliary fuel tank option is desgined so the unit can run from an external

fuel tank. The unit is still programed to shut down when the internal tank’s fuel

level drops below five percent. In order for the unit to run off of an auxiliary tank,

the fuel level in the internal tank must remain over five percent. To operate the

unit using an auxiliary fuel tank, use the following procedure:

1. Shut down the unit and check that the level of fuel in the tank is above five

percent.

2. Attach the auxiliary fuel tank's fuel lines to the “AUXILIARY FUEL INLET”

and “AUXILIARY FUEL OUTLET” fittings on the unit.

3. Open the “AUXILIARY FUEL INLET” and “AUXILIARY FUEL OUTLET”

valves located inside of the right front door.

FUEL TRANSFER PUMP OPTION

The fuel transfer pump option allows the fuel tank to be refilled from an external bulk fuel source. When the fuel

transfer switch is on, anytime the fuel level drops below 15% the fuel transfer pump will begin pumping fuel from an

external bulk fuel source into the fuel tank on the unit. The fuel transfer pump will shut off when the fuel level of the

internal tank reaches 90%. The pump will also be monitored to ensure a certain percentage increase in fuel level

over a given period of time to prevent the pump from running dry. To operate the fuel transfer system, use the following

procedure:

1. Shut down the unit. Note: if the external bulk fuel supply is already connected, the

unit does not have to be shut down to turn the fuel transfer pump option on or off.

2. Attach the external bulk fuel supply to “FUEL TRANSFER INLET” fitting on the unit.

3. Turn on the Fuel Transfer Switch.
