4.7.3 Breather Heater (Optional)
This heater is designed to prevent crankcase
breather freezing. The heater has a set point of 50° F.
If the ambient temperature inside the enclosure drops
below 50° F, the heater will automatically switch on.
Factory Breather heater is wired and requires no
further installation at site.
4.8 Generator Heater (Optional)
WARNING
Water or moisture inside a generator increases
the possibility of flashing and electrical shock,
which can cause equipment damage and severe
personal injury or death. Do not use a generator
which is not dry inside and out.
A generator heater(s) is used to help keep the gener-
ator free of condensation when the generator set is
not running. During cool and humid conditions, con-
densation may form within a generator, creating
flashing and shock hazards.
Figure 4-3 illustrates the installation of two heater ele-
ments. Connect the heater(s) to a source of power
that will be on during the time the engine is not run-
ning. Power connections are made to the terminal
block in the heater terminal box. Be sure the voltage
rating is correct for the heater element rating.
