Bryant ASPAS1BBL025 Coolant Recommendations, Before Installation, ‹ 2.1.1 Nfpa Standards

Section 2 — Installation

Bryant Liquid-cooled 25 kW Generator

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 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 ethyl- ene glycol base anti-freeze. Using any high sili- cate anti-freeze boosters or additives will also cause overheating. DO NOT use any soluble oil inhibitor for this equipment.

If an open bottom is used, the engine-genera- tor must 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.

After the system has been installed, do nothing

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

NOTE:

For more information about the installation of a standby system contact a dealer.

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 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. 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 an engineered transfer switch, if necessary.

The standard prepackaged transfer switch does not have sensing or controlling 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 distri- bution 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.
