Space Heaters
The generators used on this product can operate in high humidity conditions without problems. However, problems can occur when the generator is idle and the surrounding air is warmer than the generator. Moisture can form on the windings that will result in poor performance from the windings. Moisture can also result in damage to the windings. Whenever the generator is not active, ensure that the space heaters are in operation.
Ensure that power has been disconnected before servicing the generator terminal box.
Note: An optional attachment for space heaters may be utilized in the generator terminal box. The space heaters are a source of heat.Whenever the generator is operating, ensure that the space heaters are disconnected.An external source of either 115 VAC or 230 VAC is required to operate the space heaters.

Space heater connection to external source (H1) ( H2), (H3), and (H4) terminals.
If a 115 VAC source is available, connect both heaters in parallel across the source. If a 230 VAC source is available, connect both heaters in series across the source. Refer to Illustration 1.Gearbox Heater (If Equipped)
The gearbox can operate in normal ambient conditions without problems. Low oil temperatures can result in damage to the gearbox oil pump and sensors due to high pressure. Whenever the gearbox is not operating, ensure that the oil heater is in operation to maintain an oil temperature at or above 30° C (86° F).The gearbox heater can be operated while the gearbox is operating. A built-in thermostat will turn off the heater element as the oil temperature rises.A 120 or 240 VAC external source is required to operate the gearbox heater. The external power source voltage depends on the heater utilized on the unit. Confirm the voltage required for your specific unit prior to connecting power.
