Generac 005031-2 Coolant Recommendations, 2.1STANDBY GENERATOR INSTALLATION, Before Installation

Section 2 — Installation

Liquid-cooled 25 kW Generators

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.

1.14 COOLANT RECOMMENDATIONS

Use a mixture of half low silicate ethylene glycol base anti-freeze and half 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 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 over- heating. DO NOT use any soluble oil inhibitor for this equipment.

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.

If an open bottom is used, the engine-generator must 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.

1.15 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 the installation manual (Part No. 079699).

The generator’s rated wattage/amperage capacity must be adequate to handle all electrical loads that the unit will power. It may be necessary to group the critical (essential) loads together and wire them into a separate “emergency” distribution panel.

This generator can be installed in conjunction with a “GTS” type transfer switch, if necessary (see Section 2.9).

The standard prepackaged transfer switch (ATS mode) does not have sensing or controlling circuit boards. Instead, the generator control console hous- es a “Printed Circuit Board Assembly”, which con- trols all phases of operation, including engine start up and load transfer.

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

NOTE:

For more information about the installation of a standby system contact an Authorized Service Dealer.
