4.10 CORROSION PROTECTION

‹ 4.11.2 RETURN TO SERVICE

Periodically wash and wax the enclosure using auto- motive type products. Frequent washing is recom- mended in salt water/coastal areas. Spray engine linkages with a light oil such as WD-40.

4.11 OUT OF SERVICE PROCEDURE

‹4.11.1 REMOVAL FROM SERVICE

If the generator cannot be exercised every seven days, and will be out of service longer than 90 days, pre- pare the generator for storage as follows:

1.Start the engine and let it warm up.

2.Close the fuel shutoff valve in the fuel supply line and allow the unit to shut down.

3.Once the unit has shut down, it will signal a low oil fault.

4.Set the generator’s main circuit breaker to its OFF (or OPEN) position.

5.Set the AUTO/OFF/MANUAL switch to OFF and turn off the utility power to the transfer switch. Remove the 15A fuse from the generator control panel. Disconnect the battery cables as outlined in “General Hazards”.

6.While the engine is still warm from running, drain the oil completely. Refill the crankcase with oil. See ”Engine Oil Recommendations".

7.Attach a tag to the engine indicating the viscosity and classification of the oil in the crankcase.

8.Remove the spark plug(s) and spray fogging agent into the spark plug(s) threaded openings. Reinstall and tighten the spark plug(s).

9.Remove the battery and store it in a cool, dry room on a wooden board. Never store the battery on any concrete or earthen floor.

10.Clean and wipe the entire generator.

To return the unit to service after storage, proceed as follows:

1.Verify that utility power is turned off and that the AUTO/OFF/MANUAL switch is set to OFF.

2.Check the tag on the engine for oil viscosity and classification. Verify that the correct recommend- ed oil is used in the engine (see the Engine Oil Recommendations section). If necessary, drain and refill with the proper oil.

3.Check the state of the battery. Fill all cells of unsealed batteries to the proper level with dis- tilled water. DO NOT USE TAP WATER IN THE BATTERY. Recharge the battery to 100 percent state of charge, or, if defective, replace the battery. See “Specifications,” for type and size.

4.Clean and wipe the entire generator.

5.Make sure the 15A fuse is removed from the generator control panel. Reconnect the battery. Observe battery polarity. Damage may occur if the battery is connected incorrectly.

6.Open the fuel shutoff valve.

7.Insert the 15A fuse into the generator control panel. Start the unit by moving the AUTO/OFF/ MANUAL switch to MANUAL. Allow the unit to warm up thoroughly.

8.Stop the unit by setting the AUTO/OFF/MANUAL switch to OFF.

9.Turn on the utility power to the transfer switch.

10.Set the AUTO/OFF/MANUAL switch to AUTO.

11.The generator is now ready for service.

NOTE:

If the battery was dead or disconnected, the exer- cise timer must be reset.

Guardian Technologies has established itself as a leading provider of innovative air purification solutions, leveraging advanced technologies to create healthier indoor environments. Their product line, including models 005281, 005282, 005283, 005284, and 005280, demonstrates the company's commitment to quality, efficiency, and ease of use.

One of the outstanding features of these models is their incorporation of HEPA filtration technology. This type of filter is capable of trapping at least 99.97% of airborne particles that are 0.3 microns in diameter, which includes allergens such as pollen, dust mites, and pet dander. This ensures that users can breathe cleaner air, making these devices ideal for allergy sufferers or anyone looking to improve their indoor air quality.

In addition to HEPA filtration, Guardian Technologies' models utilize ultraviolet (UV-C) light technology. This feature targets and neutralizes airborne viruses and bacteria, further enhancing the effectiveness of the air purification process. The combination of HEPA filtration and UV-C technology makes these devices equipped to handle a wide range of indoor air quality concerns.

Another significant characteristic of these products is their energy efficiency. Designed to operate quietly and with low power consumption, these air purifiers are not only effective but also environmentally friendly. Users can enjoy clean air without worrying about their energy bills or the environmental impact.

Furthermore, the user-friendly design of these models is notable. Many units come with intuitive controls, multiple fan speeds, and filter replacement indicators, making it easy for users to maintain optimal performance. Some models may also feature smart capabilities, allowing users to monitor air quality levels and control the device remotely via a smartphone app.

Durability is another hallmark of Guardian Technologies. Their products are built to last, using high-quality materials and components that ensure long-term reliability. This commitment to longevity adds value to the investment, as users can expect years of effective air purification.

In conclusion, Guardian Technologies' models 005281, 005282, 005283, 005284, and 005280 embody innovative features and technologies that cater to diverse air quality needs. From advanced filtration systems to energy-efficient designs, these purifiers not only enhance indoor air quality but also promote a healthier living environment for all users.
