Carburetor Heater (Optional) - Kohler 12RESM1 Installation Manual

1.10 Carburetor Heater (optional)

Have accessories installed by an authorized distributor/
dealer or a licensed electrician. Follow the installation
instructions provided with each kit. Use separate conduit
for AC and DC leads to reduce the possibility of electrical
interference. Verify that the leads and conduit do not
interfere with the operation of the generator set or
obstruct the service areas. Verify that the electrical
installation complies with the National Electrical Code
(NEC) and all applicable local codes. See Section 2,
Wiring Diagrams, for more information regarding
generator set electrical connections.
An optional carburetor heater is recommended for
improved cold starting in locations where the ambient
temperature drops below 0_C (32_F). The carburetor
heater prevents condensation and carburetor icing. The
heater turns on when the temperature at the thermostat
falls below approximately 4_C (40_F) and turns off when
the temperature rises above approximately 16_C
(60_F). See Figure 1-23 through Figure 1-26.
The heater thermostat is installed in the cord.
Figure 1-26 shows the location of the thermostat on the
power cord.
