Operation Manual
GENERATOR INSTALLATION  
In RECREATIONAL VEHICLES
INTRODUCTION
  Use this section as a guide when installing a generator set in a recreational vehicle, and then refer 
to the appropriate operation section for specific instructions. When installing a RV generator set the 
installation must comply with the current Safety Standards of ANSI / RVIA EGS-1-2003, ANSI A 119.2 
/ NFPA 501C and applicable articles of ANSI / NFPA 70 of the National Electrical Code. Generator set 
installations must also comply with state and local requirements. 
MARINE APPLICATION 
  RV generator sets do not comply with United States Coast Guard (USCG) requirements and 
must not be used for marine applications. Use only generator sets specified for marine use in marine 
installations. USCG regulation 33CFR183 requires a generator set to be “ignition protected” when used 
in a gasoline fueled environment. 
GENERAL INFORMATION 
This information section covers the RV generator set models listed below. To determine which 
model is involved, check the model number found on the Power Technology nameplate attached to the 
frame of the generator being installed. Follow all instructions to ensure proper installation and operation. 
  Each generator set features a Kubota diesel engine, rotating-field alternating current generator, 
and a control box. The generator is directly connected to the engine for permanent alignment. Each 
control box includes a Start / Stop switch, and a On /Off switch to reset the control module or lockout 
any remote switch to prevent starting while service is being performed. The control box may also be 
equipped with a switch to operate the mechanism used to move the generator in/out of the coach for 
servicing. (Supplied by the coach manufacture). After the set is attached to the frame of the vehicle, all 
that is usually required to make it operational is the following. 
1. Attaching the exhaust system. 
  2. Add proper amount of radiator coolant. 
  3. Add oil to crankcase, to the dipstick FULL mark. 
  4. Connect fuel lines, remote switch, load leads and battery terminals.
