Guardian Liquid-cooled 15 kW, 20 kW and 25 kW Generators

‹4.6.3 BATTERY MAINTENANCE

The battery should be inspected per the “Scheduled Maintenance,” Section 4.7. The following procedure should be followed for inspection:

1.Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary.

2.Check the battery fluid level of unsealed batteries and, if necessary, fill with DISTILLED WATER ONLY. DO NOT USE TAP WATER IN BATTERIES.

3.Have the state of charge and condition checked. This should be done with an automotive-type bat- tery hydrometer.

DANGER

Storage batteries give off explosive hydrogen gas. This gas can form an explosive mixture around the battery for several hours after charging. The slightest spark can ignite the gas and cause an explosion. Such an explosion can shatter the battery and cause blindness or other injury. Any area that houses a storage battery must be properly ventilated. Do not allow smoking, open flame, sparks or any spark producing tools or equipment near the battery.

Battery electrolyte fluid is an extremely caustic ! sulfuric acid solution that can cause severe

burns. Do not permit fluid to contact eyes, skin, clothing, painted surfaces, etc. Wear protective goggles, protective clothing and gloves when handling a battery. If the fluid is spilled, flush the affected area immediately with clear water.

Be sure the AUTO/OFF/MANUAL switch is set to ! the OFF position before connecting the battery cables. If the switch is set to AUTO or MANUAL,

the generator can crank and start as soon as the battery cables are connected.

Be sure the utility power supply is turned off, or sparking may occur at the battery posts as the cables are attached and cause an explosion.

‹4.6.4 BATTERY REPLACEMENT

When replacing batteries, use the same number and the type of battery that follows:

 

BCI Group No.

Generac is renowned for its innovation in the power generation industry, and their range of generators—including models 0047210, 0047220, 0047230, 0047240, 0047250, 0047251, 0047252, 0047253, and 0047260—showcase advanced technologies and functionality that meet diverse power needs.

One of the standout features of these models is the use of Generac’s G-Force Engine, specifically designed for reliability and longevity. This engine is notorious for its durability, capable of handling demanding workloads and proving to be more efficient than typical engines found in similar generators. It provides quick start times, lower emissions, and is built to withstand extended operational cycles.

Another notable technology in these models is the Quiet-Test™ mode, which enables the generator to run at a lower RPM while it performs an exercise routine. This feature not only reduces noise during operation but also conserves fuel, making it an eco-friendly option that doesn’t compromise on performance.

The generators are equipped with advanced monitoring and control features, including the Mobile Link™ application compatibility. This allows users to monitor the status of their generator remotely via a smartphone or tablet, offering peace of mind and real-time access to the generator's operational functioning. This connectivity also enables the user to receive alerts and notifications about maintenance needs or when the generator is in need of attention.

In terms of design, these models boast a robust steel enclosure that offers superior protection against the elements, thereby enhancing durability and ensuring efficient operation regardless of weather conditions. The enclosures also come with a weather-resistant finish, making them suitable for outdoor installation.

Moreover, the generators feature a well-thought-out installation process with easily accessible controls and noise-reduction technology, which helps minimize disturbances for residential applications. They also offer multiple power outputs, catering to varied energy needs, from essential home appliances to larger devices.

Safety is a core consideration with Generac models, and features such as the automatic shutdown mechanism prevent overheating, ensuring operational safety during use. Coupled with an efficient fuel consumption rate, these generators stand out as impeccable solutions for power backup in homes and businesses alike.

The series exemplifies Generac’s commitment to excellence in power solutions, integrating user-friendly technology, efficient performance, and top-tier safety into compact, durable designs. Users can rely on models 0047210 to 0047260 for dependable power generation tailored to their specific needs.
