DIAGNOSTIC TESTS

Connect one meter test lead to pin location J2-10 Wire 44S of the connector just removed. Be careful not to damage the pin connectors with the test leads. Connect the other meter test lead to Wire 44S at Terminal Block 2 (TB2). CONTINUITY should be measured.

3.Connect one meter test lead to pin location J2-12 Wire 11S. Be careful not to damage the pin connectors with the test leads. Connect the other meter test lead to Wire 11S at Terminal Block 2 (TB2). CONTINUITY should be measured.

RESULTS:

1.If CONTINUITY was not measured, repair or replace the wire harness.

2.If CONTINUITY was measured, refer back to the flow chart.

TEST 52 - CHECK IDLE CONTROL SWITCH

(SW2)

PROCEDURE:

1.Set a voltmeter to measure resistance.

2.Disconnect Wire 0 and Wire 83 from the Idle Control Switch (SW2).

3.Connect meter test leads across both terminals of SW2. See Figure 6-59.

4.In the OFF position the meter should read INFINITY or Open. In the ON position the meter should read CONTINUITY or Closed.

RESULTS:

1.If the switch fails Step 4 replace it.

2.If the switch is good refer back to the flow chart.

TEST 53 - CHECK IDLE CONTROL WIRING

PROCEDURE:

1.Set a voltmeter to measure resistance.

2.Disconnect Wire 0 from the Idle Control Switch (SW2).

3.Connect one meter test lead to Wire 0. Connect the other meter test lead to frame ground. CONTINUITY should be measured. If continuity is not measured repair or replace Wire 0 between SW2 and the ground terminal.

4.Disconnect Wire 83 from SW2. Disconnect the J2 connector from the printed circuit board.

5.Connect one meter test lead to Wire 83 previously removed from SW2. Connect the other meter test lead to pin location J2-2 on the J2 connector. See Figure 6-60. Be careful not to damage the pin connectors with the test leads. CONTINUITY should be measured. If CONTINUITY is not measured repair or replace Wire 83 between the J2 connector and Terminal Block or between the Terminal Block and SW2.

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.
