5.1 Introduction

This section describes some of the accessories that are available for the generator sets. Have accessories installed by an
authorized dealer or a licensed electrician. This document does not contain installation instructions for accessories. 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 the wiring diagrams in the Drawings and Diagrams
section for more information regarding generator set electrical connections.

5.2 Carburetor Heater

WARNING
Servicing the engine heater. Hot parts can cause minor personal injury or property damage. Install the heater before
connecting it to power. Operating the heater before installation can cause burns and component damage. Disconnect power to
the heater and allow it to cool before servicing the heater or nearby parts.
A 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).
The carburetor heaters are shown in Figure 37.
To install the carburetor heater, follow the instructions provided with the kit. Figure 38 shows the installed carburetor heater kit
installed for a 14 kW generator set. Figure 39 shows the location for the carburetor heater kit on an 20/26 kW generator set.
Note:
The breather tube heater and oil heater kit cannot be used with a carburetor heater.
Verify that AC power is connected to the generator set as described in the Electrical Connections section. Make sure that the
circuit is backed up by the generator set to provide power at all times.
The heater thermostat is installed in the cord. Figure 37 shows the location of the thermostat on the power cord. The heater
power cord and thermostat are located in the generator set housing air intake area/ battery compartment.
For 120 volt models, plug the carburetor heater into the 120 VAC receptacle provided. 240 volt kits use a 3-pin power connector.
Knockouts are provided for the 240 V plugs. See Figure 40 and follow the instructions provided with the heater kits.
