Section 1 — Installation
Guardian
1.3BEFORE INSTALLATION
Before installing this equipment, check the ratings of both the generator and the transfer switch. Read “Emergency Circuit Isolation Method” and “Total Circuit Isolation Method” in Sections 1.8 and 1.9 (Page 11) carefully.
The generator's rated wattage/amperage capacity must be adequate to handle all electrical loads that the unit will power. You may have to group the criti- cal (essential) electrical loads together and wire them into a separate emergency distribution panel.
NOTE:
In some areas, you may need to acquire electrical permits for installing an emergency system, build- ing permits for installing gas lines, and permits for noise allowances. Check your local codes before installing the unit.
1.4LIFTING THE GENERATOR
To lift a nonsound attenuated generator, insert pipe having sufficient strength and diameter through the lift- ing holes (lifting brackets are provided with sound attenuated units), which are located near the unit’s base (see Figure 1.1). You also may lift the unit using a hook and hoist method provided you use a spreader bar to ensure that the lines clear the roof.
Figure 1.1 – Location of Lifting Holes/Brackets
(6 kW, 8 kW and 10 kW)
(Sound Attenuated)
When lifting or hoisting equipment is used, be careful not to touch overhead power lines.
The generator’s weight of more than 300 pounds requires proper tools and equipment, and qualified personnel to be used in all phases of handling and unpacking.
Exercise caution when lifting the unit manually as it may shift on lifting pipes during transportation, which may result in injury.
The generator was not designed to be lifted by its roof. Use the lifting holes or brackets provided near the base of the unit. If using a hook and hoist lifting method, you must employ a spreader bar to prevent from crushing the roof.
1.5ENGINE OIL RECOMMENDATIONS
Use oil of American Petroleum Institute (API) Service Class SG, SH or SJ. Select the viscosity based on the air temperature at the time of operation. See the fol- lowing chart:
Temperature | Oil Grade (Recommended) |
Above | SAE |
Below | SAE |
All Seasons | SAE |
|
|
*Organic
Any attempt to crank or start the engine before it has been properly serviced with the recom- mended oil may result in an engine failure.
1.6GASEOUS FUEL SYSTEM
NOTE:
The following information pertaining to gaseous fuel systems is provided to assist gaseous fuel technicians in planning installations. In no way should this information be interpreted to conflict with applicable fuel gas codes. Consult with your local fuel supplier or fire marshall if questions or problems arise.
◆1.6.1 FUEL SYSTEM REQUIREMENTS AND RECOMMENDATIONS
When installing the fuel system, install a flexible length of line between the generator fuel connec- tion and the rigid piping. The flexible hose must be approved for use with gaseous fuels. It is rec- ommended that an emergency manual fuel shutoff valve be placed
