JACKET WATER HEATER AND INTERNAL BATTERY

CHARGER 120 VAC INPUT RECEPTACLES

(OPTIONAL)

This generator can be equipped as an

option

with a

engine block heating element

and an

internal battery

charger

. They are provided with electric cords to connect

to a commercial power source.
The engine block heating element and internal battery

charger both require 120 VAC in order to operate. A

receptacle (Figure 66) has been provided on the output

terminal panel to allow commercial power to be applied.
These units will

ONLY

function when commercial power

has been supplied to them. When using extension cords,

refer to Table 6 for the correct size and length.
The battery charger should always be connected to a

commercial power source to ensure that the battery does

not get discharged.

When using the generator in

hot

climates there is no

need to apply power to jacket water heater. However, if the

generator will be used in

cold

climates, it is best to apply

power to the jacket water heater at all times.
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 a

power cord of adequate size.

NOTICE

To ensure adequate starting capability, always have

power applied to the generator's internal battery

charger.
