2.3.4 TESTING THE INSTALLATION

The manufacturer recommends testing the installa- tion to be sure adequate cooling airflow is available to the unit before placing the unit into service. If the unit shows signs of overheating, enlarge the air openings. Never place a unit into service until absolutely certain that cooling and ventilation is adequate.

NOTE:

The installation must be tested, especially if air is brought in from below the generator set.

2.4GASOLINE FUEL SYSTEM

The installation of a gasoline fuel system (Figure 2.14) for a recreational vehicle generator set must comply with applicable codes, standards and regula- tions. The entire fuel system must be completely free of leaks. There must be no possibility of gasoline vapors entering the vehicle interior.

2.3.3 COMPENSATING FOR RESTRICTIONS

Such materials as screening, louvers or expanded metal can restrict the free flow of air. Compensate for this restriction by making the actual air opening proportionately larger.

Some materials may offer only a 60 percent “free air inlet area.” Other more efficient materials may pro- vide up to a 90 percent free air inlet area. The per- centage of free air inlet opening is usually available from the material supplier or manufacturer.

To determine the actual air inlet opening size required, divide 100 square inches by the per- centage of free air inlet area for the material being used.

For example: If planning to use screening with an 80 percent free air inlet area, divide 100 by 0.8, which results in 125 square inches. Minimum actual size of air inlet opening in this case is 125 square inches.

FUEL PUMP

FUEL FILTER

DANGER

Gasoline is highly flammable, and its vapors are explosive. Comply with all codes, standards and regulations pertaining to gasoline fuel systems used in recreational vehicle generators. Properly install and maintain the fuel system and keep it entirely free of leaks. Gasoline vapors must not enter the vehicle interior.

Factory installed generator fuel system components include (a) fuel filter, (b) 12-volt DC electric pump,

(c)engine carburetor, and (d) interconnecting lines and fittings. Connect a fuel supply line to the fuel filter inlet. Use a flexible length of approved fuel hose between the fuel filter inlet connection and rigid fuel lines.

02010-2, 04164-3 specifications

Guardian Technologies has made a significant impact in the air purification industry with its range of innovative products, particularly the models 02010-2 and 04164-3. These air purifiers are designed to enhance indoor air quality by leveraging advanced technologies, making them popular choices for both home and office environments.

The Guardian Technologies 02010-2 is an impressive model known for its portable design and effective purification capabilities. It features a 3-in-1 air cleaning system that includes a HEPA filter, a charcoal filter, and a UV-C light. The HEPA filter is essential for capturing allergens such as pollen, dust mites, and pet dander, making it ideal for allergy sufferers. The charcoal filter helps eliminate odors, capturing smoke and volatile organic compounds, while the UV-C light helps reduce germs and bacteria, ensuring a cleaner atmosphere.

This model is compact, allowing it to fit seamlessly into small spaces, while still providing powerful purification performance. With a whisper-quiet operation, it can be used in bedrooms or workspaces without causing disruption. Additionally, it features an adjustable fan speed, enabling users to customize the airflow according to their preference, along with an energy-efficient design that helps reduce power consumption.

On the other hand, the Guardian Technologies 04164-3 introduces a more advanced air purification system with similar foundational features but enhances the user experience with added functionalities. This model typically incorporates a combination of a HEPA filter and a UV-C light as well, but it often boasts smart capabilities. These may include an air quality sensor that helps monitor particulate levels in real-time, automatically adjusting the purification level when needed. This intelligent feature ensures that the air quality remains at optimal levels without requiring constant manual adjustments.

Both models prioritize user convenience, sporting features like filter replacement indicators, ensuring timely maintenance of the purification system. They are designed for ease of use and portability, allowing consumers to move them effortlessly from room to room.

In summary, Guardian Technologies’ models 02010-2 and 04164-3 stand out in the air purifier market due to their advanced filtration systems, ease of use, and smart technologies. These air purifiers are key investments for anyone looking to improve their indoor air quality effectively.
