Port 1 is for NG only and Port 2 is for LP vapor only. No provision for simultaneous fuels has been made.

DANGER

Serious injury or damage may occur if not con-

!figured properly. Please consult an authorized Generac Service Dealer with any questions.

1.14 ENGINE OIL RECOMMENDATIONS

The unit has been filled with 15W-40 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 ambient temperature range anticipated before the next oil change:

 

Temperature

Oil Grade (Recommended)

 

 

Above 80° F (27° C)

SAE 30W or 15W-40

 

 

32° to 80° F (-1° to 27° C)

SAE 20W-20 or 15W-40

 

 

Below 32° F (0° C)

SAE 10W or 15W-40

 

 

 

 

 

 

 

 

 

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.

1.15 COOLANT RECOMMENDATIONS

Use a mixture of half low silicate ethylene glycol base anti-freeze and deionized water. Cooling system capacity is about 8 U.S. quarts (7.6 liters). Use only deionized 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 chromi- umhydroxide (“green slime”) forms and will cause overheating. Engines that have been operated with a chromate base rust inhibitor must be chemically cleaned before adding eth- ylene glycol base anti-freeze. Using any high silicate anti-freeze boosters or additives will also cause overheating. Generac Power Systems also recommends that any soluble oil inhibitor is NOT used for this equipment.

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.

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 a standard Generac “GTS” type transfer switch, if desired.

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.

2.1STANDBY GENERATOR INSTALLATION

DANGER

Connecting this generator to an electrical sys- tem 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 sys- tem 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.

If an open bottom is used, the engine-genera- tor is to be installed over non-combustible materials and should be located such that com- bustible materials are not capable of accumu- lating 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.

This genset must be installed on a level surface. The base frame must be level within 1/2 inch all around.

After the system has been installed, do nothing

!that might render the installation in noncompli- ance with such codes, standards and regula- tions.
