This generator is equipped with two 120 VAC, 20 amp input receptacles located on the output terminal panel.

The purpose of these receptacles is to provide power via commercial power to the jacket water heater and internal battery charger.

These receptacles will ONLY function when commercial power has been supplied to them (Figure 75). To apply commercial power to these receptacles, a power cord of adequate size will be required (See Table 5).

When using the generator in hot climates there is no reason to apply power to jacket water heater. However, if the generator will be used in cold climates it is always a good idea to apply power to the jacket water heater at all times.To apply power to the jacket water heater simply apply power to the jacket water heater receptacle via commercial power using an power cord of adequate size.

If the generator will be used daily, the battery should normally not require charging. If the generator will be idle (not used) for long periods of time, apply power to the battery charger receptacle via commercial power using an power cord of adequate size.

To ensure adequate starting capability, always have power
