1.14 ENGINE OIL RECOMMENDATIONS

The unit has been filled with 5W-20 engine oil at the factory. Use a high-quality detergent oil classified “For Service CC, SD, SE, SF.” Detergent oils keep the engine cleaner and reduce carbon deposits. Use oil having the following SAE viscosity rating, based on the ambi- ent temperature range anticipated before the next oil change:

The generator’s rated wattage/amperage capacity must be adequate to handle all electrical loads that the unit will power. The critical (essential) loads may need to be grouped together and wired into a sepa- rate “emergency” distribution panel.

This generator can be installed in conjunction with an engineered “GTS” type transfer switch, if neces- sary.

The standard transfer switch has no sensing or con- trolling circuit boards. Instead, the generator control console houses a “Printed Circuit Board Assembly”, which controls all phases of operation, including engine start up and load transfer.

	Temperature	Oil Grade (Recommended)
	Above 80° F (27° C)	SAE 5W-20
	32° to 80° F (-1° to 27° C)	SAE 5W-20
	Below 32° F (0° C)	SAE 5W-20

NOTE:

Synthetic oil is highly recommended in any element with temperatures above 90° F or below 30° F.

Any attempt to crank or start the engine before it has been properly serviced with the recommend- ed oil may result in an engine failure.

2.1STANDBY GENERATOR

INSTALLATION

DANGER

Connecting this generator to an electrical system normally supplied by an electric utility shall be by means of a transfer switch, so as to isolate the electric system from the utility distribution system when the generator is operating. Failure to isolate the electric system by these means will result in damage to the generator and may also result in injury or death to utility workers due to backfeed of electrical energy.

1.15 COOLANT RECOMMENDATIONS

Use a mixture of half low silicate ethylene glycol base anti-freeze and half de-ionized water. Cooling system capacity is about 12 U.S. quarts (11.4 liters). Use only de-ionized water and only low silicate anti-freeze. If desired, add a high quality rust inhibitor to the rec- ommended coolant mixture. When adding coolant, always add the recommended 50-50 mixture.

Do not use any chromate base rust inhibitor with ethylene glycol base anti-freeze or chro- miumhydroxide (“green slime”) forms and will cause overheating. Engines that have been oper- ated with a chromate base rust inhibitor must be chemically cleaned before adding ethylene glycol base anti-freeze. Using any high silicate anti-freeze boosters or additives will also cause overheating. It is also recommend that any solu- ble oil inhibitor is NOT USED for this equipment.

1.16 BEFORE INSTALLATION

Before installing this equipment, check the ratings of both the generator and the transfer switch. Read “Emergency Isolation Method” and “Total Circuit Isolation Method” in Sections 2.5 and 2.6.

If an open bottom is used, the engine-generator is to be installed over non-combustible materi- als and should be located such that combustible materials are not capable of accumulating under the generator set.

Only qualified, competent installation contractors or electricians thoroughly familiar with applicable codes, standards and regulations should install this standby electric power system. The installation must comply strictly with all codes, standards and regula- tions pertaining to the installation.

After the system has been installed, do nothing that might render the installation in noncompli- ance with such codes, standards and regulations.
