Power Tech Generators PTS-20KSI-3-3 Operator's Manual page 22

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.
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.
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 are 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.
