QUIETPACT 55, 65, and 75 Recreational Vehicle Generators

◆6.2.4 ACOUSTICS

For additional noise abatement, the installer may wish to consider the following:

•Using special sound insulating materials.

•Construction of a special noise abatement com- partment.

NOTE:

Any method used to reduce noise must not adversely affect the flow of cooling and ventilating air into or out of the compartment.

In addition to the effective use of sound insulating materials, construction of a special noise abatement compartment might be considered to reduce noise levels. Such a compartment might be constructed as follows (Figure 6.7):

•Use 5/8-inch thick or 3/4-inch thick plywood in the compartment.

•Construct the compartment floor of a double thick- ness of 5/8-inch or 3/4-inch plywood.

•Line the compartment interior walls and floor, as well as the underside of the floor, with 26-gauge galvanized steel.

•Vapor seal all compartment seams and joints.

•Over the galvanized steel lining, install a combina- tion of acoustical materials as mentioned in Section 6.2.3.

DANGER

To prevent fire or explosion, do not install any insulation or other absorbent materials on the interior or underside of the compartment floor.

•Seal all compartment door edges to prevent noise leakage around the door perimeter.

•Line the compartment door interior (except for air openings) with suitable, fireproof sound insulation (such as 1-inch (25 mm) thick fiberglass with a 2- pound density).

◆6.2.5 COMPARTMENT FLOOR CUTOUTS

You must provide openings in the generator compart- ment for the following items (Figure 6.8, Page 26):

•Engine exhaust and cooling air outlets

•Generator cooling air inlet

•Four holes for passage of generator mounting bolts. See Section 6.1.4 (Page 23).

DANGER

Fuel lines and exhaust piping must not pene-

!trate into the vehicle living area.

6.3COOLING AND VENTILATING AIR

It is absolutely essential that an adequate flow of air for cooling, ventilating and engine combustion be supplied to the generator set. Without sufficient air- flow, the engine/generator quickly overheats. Such overheating can cause serious operating difficulties and also may cause fire and personal injury. The installer must make sure that sufficient air is avail- able to the generator for cooling, ventilating and com- bustion. The installer also must provide for a path for exhausting the cooling air to the exterior of a com- partment, if so equipped.

DANGER

Never use discharged cooling air for heating or permit such air to enter the vehicle interior. This air contains deadly carbon monoxide gas and other poisonous, flammable or explosive gases.

◆6.3.1 GENERATOR AIRFLOW

Engine operation drives cooling fans for the two-stage cooling air system. A pressure fan draws cooling air into the top of the generator (Figure 6.9). This airflow cools the engine/generator and electronic compo- nents. The second part of the cooling system, a suc- tion fan, draws air that is heated from a hot engine into a collector pan at the base of the unit. This heat- ed air (although cooler than exhaust muffler) is then deflected out the bottom toward the ground.

Generac has established itself as a leader in the power generation industry, particularly noted for its wide range of generators designed to provide reliable backup power. Among its various models, the Generac series consisting of the 004702-0, 004703-0, 004704-0, 004705-0, 004706-0, and 004707-0 stands out due to their dependable performance and innovative features. Each model in this series is engineered for both residential and light commercial applications, offering peace of mind during power outages.

One of the main features of these models is their state-of-the-art engine technology. Equipped with a Generac engine, these generators are designed to provide efficient, powerful performance. The engines are robust and designed to withstand extended use, ensuring that users can rely on them when needed most.

A standout feature is their Automatic Transfer Switch (ATS) capability. When the power goes out, these generators automatically switch on, providing uninterrupted power to essential appliances and systems in the home. This seamless transition is vital for maintaining safety and comfort during outages, eliminating the need for manual intervention.

Fuel efficiency is another area where these models excel. They utilize either natural gas or propane, offering flexibility in fuel choice depending on availability and preference. Their engineering is optimized for minimal fuel consumption while maximizing output, making them a cost-effective solution for power needs.

Furthermore, these models incorporate advanced monitoring and control systems. Users can conveniently monitor generator performance and status through an intuitive mobile app or control panel. This technology allows users to receive alerts and updates, ensuring they are always informed about the power situation at their location.

Noise reduction technology is also a key characteristic of this series. Generac's engineers have focused on minimizing sound output, providing a quieter operation compared to many other generators in the market. This feature is particularly beneficial for residential areas where noise can be a significant concern.

Overall, the Generac 004702-0, 004703-0, 004704-0, 004705-0, 004706-0, and 004707-0 models exemplify reliability, efficiency, and advanced engineering. Their comprehensive features and user-friendly technology make them an excellent choice for anyone seeking a dependable backup power solution.
