IMPACT-36 plus II Recreational Vehicle Generator

DANGER: For fire safety, installation of a generator into a recreational vehicle must comply

! strictly with NFPA 70 (latest edition), “National Electrical Code”, Article 551, and NFPA 1192 !

(latest edition), “Standard for Recreational Vehicles”. In addition, installation must comply with the manufacturer’s instructions and recommendations.

NOTICE TO INSTALLER

These Installation Instructions have been published by Generac to aid in the installation of the products described in this manual. Generac assumes that installation personnel are familiar with the procedures for installing such products, or similar products that Generac manufactures. Generac also assumes that personnel have been trained in the recommended installation procedures for these products and that such training includes (a) use of common hand tools,

(b)use of special Generac tools, and (c) use of any tools and/or equipment from other suppliers.

Generac cannot possibly know of, nor advise the recreational vehicle trade of, all conceivable methods, procedures, or techniques by which to perform an installation. Nor can Generac anticipate every possi- ble hazard that might result from each installation method, procedure, or technique. Generac has not undertaken any such wide evaluation. Therefore, people who use a method, procedure, or technique that Generac does not specifically recommend must first completely satisfy themselves that their safety, the safety of the vehicle's occupants, and the prod- uct's safety are not endangered by the method, pro- cedure, or technique selected.

Information, illustrations, specifications, etc., con- tained in these Installation Instructions are based on the latest information available at the time of publi- cation.

However, the manufacturer reserves the right to change, alter, or otherwise improve this product at any time, with- out prior notice.

Manual backgroundManual background DANGER

Despite the safe design of this generator,

!operating this equipment imprudently, neglecting its maintenance, or being careless can cause possible injury or death. Permit only responsible and capable persons to operate or maintain this equipment.

Parts of the generator are rotating and/or hot

!during operation. Exercise care near running generators.

Potentially lethal voltages are generated by these machines. Ensure all steps are taken to render the machine safe before attempting to work on the generator.

! GENERAL HAZARDS !

For safety reasons, Generac recommends that the installation, initial startup, and maintenance of this equipment is carried out by a Generac Authorized Service Dealer.

The engine exhaust fumes contain carbon monox- ide, which can be DEADLY. This dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death. This exhaust sys- tem must be installed properly, in strict compli- ance with applicable codes and standards. Following installation, do nothing that might ren- der the system unsafe or in noncompliance with such codes and standards. The generator com- partment must be completely vapor-sealed from the vehicle interior. There must be no possibility of exhaust fumes entering the vehicle interior. Never operate this equipment with a leaking or defective exhaust system.

Keep hands, feet, clothing, etc., away from drive belts, fans, and other moving or hot parts. Never remove any drive belt or fan guard while the unit is operating.

Adequate, unobstructed flow of cooling and ven- tilating air is critical to correct generator oper- ation and is required to expel toxic fumes and fuel vapors from the generator compartment. Without sufficient cooling airflow, the engine/generator quickly overheats, which caus- es serious damage to the generator. Do not alter the installation or permit even partial blockage of ventilation provisions, as this can seriously affect safe operation of the generator.

When working on this equipment, remain alert at all times. Never work on the equipment when physically or mentally fatigued.

Before performing any maintenance on the genera- tor, disconnect its battery cables to prevent acci- dental startup. First, disconnect the cable from the battery post, indicated by a NEGATIVE, NEG, or

(–). Reconnect that cable last.

Never use the generator or any of its parts as a step. Stepping on the unit can stress and break parts, and may result in dangerous operating con- ditions from leaking exhaust gases, fuel leakage, oil leakage, etc.

Never insert any tool or other object through open- ings in the generator interior, even if the unit is not running. Seriouse injury or damage to the equip- ment may occur.
