DIAGNOSTIC TESTS

RESULTS:

1.If continuity or zero was measured in Step 3 or Step 4 replace the FSS.

2.(Units without Hourmeter) If correct resistance was measured refer to flow chart, repair or replace Wire 14 between the FSS and Resistor (R1).

3.(Units with Hourmeter) Refer back to flow chart.

TEST 48 - CHECK HOURMETER

PROCEDURE:

1.Disconnect Wire 14 from the hourmeter. Install new 10 Amp fuse. Set Start Run Stop Switch (SW1) to start.

2.Check to see if fuse blew open.

RESULTS:

1.If fuse did not blow open replace the hour meter.

2.If fuse still blew repair or replace Wire 14 between the Resistor (R1) and the Hour Meter (HM) or between the HM and the Fuel Shutoff Solenoid (FSS).

RESULTS:

1.If continuity was measured in Step 2 but not in Step 3, replace the printed circuit board.

2.If continuity was measured in Step 3, Wire 15B is shorted to ground, repair or replace Wire 15B between the SSR and printed circuit board.

TEST 50 - CHECK WIRE 167

PROCEDURE:

1.Set a voltmeter to measure resistance.

2.Disconnect Wire 167 from the Start-Run-Stop Switch (SW1). Connect one meter test lead to Wire 167 previously removed. Connect the other meter test lead to frame ground. See Figure 6-57. INFINITY should be measured.

3.If continuity or zero resistance was measured remove the J2 connector from the printed circuit board and repeat Step 2.

TEST 49 - CHECK WIRE 15B

00

OL

PROCEDURE:

1.Set a voltmeter to measure resistance.

2.Disconnect Wire 15B from the Start Stop Relay (SSR) (see Figure 6-56) . Connect one meter test lead to Wire 15B previ- ously removed. Connect the other meter test lead to frame ground. Approximately 20K ohms should be measured.

3.If continuity or zero resistance was measured remove the J2 connector from the printed circuit board and repeat Step 2.

RESULTS:

1.If continuity was measured in Step 2 but not in Step 3, replace the printed circuit board.

2.If continuity was measured in Step 3 wire 167 is shorted to ground, repair or replace Wire 167 between the SW1 and printed circuit board.

TEST 51 - CHECK Wires 11S & 44S

PROCEDURE:

1.Set a voltmeter to measure resistance.

2.Disconnect the J2 connector from the printed circuit board.

5308, 4583, 4451 & 4986, 4582 & 4987 specifications

Guardian Technologies has carved a niche in the market with its innovative air purification and UV-C sanitization products. The company's model numbers, including 4582, 4987, 4451, 4986, 4583, and 5308, represent a diverse range of solutions designed to enhance indoor air quality and safety in both residential and commercial settings.

The Guardian Technologies 4582 is equipped with a true HEPA filter that captures 99.97% of dust, pollen, smoke, and other particles as small as 0.3 microns. This model features a smart sensor that adjusts the fan speed according to the air quality in real-time. The UV-C light technology integrated into this device works to eliminate viruses and bacteria, providing an additional layer of protection against airborne pathogens.

The 4987 model follows suit with similar advanced features but adds a sleek design ideal for modern interiors. With multiple speed settings and a night mode, the 4987 is perfect for bedrooms or quiet spaces. Its energy-efficient operation coupled with an indicator that signals filter replacement ensures that users maintain optimal performance effortlessly.

The Guardian Technologies 4451 and 4986 models are particularly notable for their enhanced capacity and filtration efficiency. Both units incorporate a three-in-one filtration system that includes a pre-filter, activated charcoal filter, and HEPA filter. With their strategic design, these models not only purify the air but also trap common household odors, making them a popular choice for families with pets.

The 4583 model stands out with a unique combination of design and functionality. It features a low-profile design, making it easy to fit into any space. Its UV-C light technology not only disinfects air but can also sanitize surfaces, bridging the gap between air purification and direct sanitation.

Finally, the Guardian Technologies 5308 caters to larger spaces, offering impressive air circulation and filtration capabilities. Equipped with a high-efficiency particulate air (HEPA) filter and a powerful fan, it effectively cleans larger areas while maintaining whisper-quiet operation.

In summary, Guardian Technologies’ products exemplify a commitment to improving air quality and promoting health through innovative technology. With features like HEPA filtration, UV-C sanitization, smart sensors, and sleek designs, consumers can choose from a range of models that best fit their needs, ensuring cleaner, safer indoor environments.
