Honeywell Power Supply for F300 F50F F58 Series Two

Setting Ionizer Current Jumper P5

The power supply can be configured for five air cleaner sizes: 12½x20, 16x20, 16x25, 20x20, 20x25. A jumper on the power supply board needs to be set based on the overall size of your collector cells. This jumper (P5) sets the ionizer current. The P8 jumper drops the voltage from 8150v to 7500v for ozone reduction.

Power Supply Ground Choke Installation

The Honeywell power supply kit comes with an additional ground wire choke. Basically the ground choke is connected in conjunction with your existing powercord ground wire and the metal chassis. This component is essential to protect the power supply. Earth/ground line choke eliminates ground loop frequencies. This prevents fault in your unit caused by ground conductor loops and power surge.

Determining Series One or Series Two

Use the Series One power supply if your current power box has the terminal strip for the W8600E. The terminal strip on power boxes made from 1994 to 1997 have pin connectors not compatible with the current power supply. Thus the Series One replacement power supply also includes the terminal strip and wire harness.

If you are replacing a power supply that has an existing W8600F, then order the Series Two power supply and reuse the existing terminal strip and harness. You also reuse the small daughter card that plugs in to the power supply. These items were originally supplied with the W8600F.

If your power box has a terminal strip with nothing connected because you are not using a W8600E or W8600F, then use the Series One power supply. Otherwise the Series Two does not have the terminal strip and the old terminal strip will be left to dangle.

The W8600F was introduced in 1998 and was originally available in white or taupe, but the taupe was discontinued mid 2006. The W8600F is now only available in white.

Though the W8600E was replaced by the W8600F in 1998, the W8600E was available as a replacement part until 2004. We no longer have any W8600E left.

Plug Versus Pin AFS Connectors

The photo below shows the replacement power supply and a Series Two air flow sensor plug connection.
The photo below shows the same replacement power supply but a Series One pin connection. This Air Flow Sensor would be the type found in a Series One power box. Pin connectors are also used for connecting the neon lamp and terminal strip for the W8600E.
Only the Series One power supply includes instructions. The instructions show the wiring diagram for the Series One pin connections. The Series Two power supply does not include instructions because the plug connectors are simple.

Power Supply Bench Test

Here is our procedure to test the power supply. Warning high voltage shock can cause death.

The power supply has the option to disable the air flow sensor. The AFS can be temporary disabled by shorting two pins marked "bypass AFS" found on J3 AFS connection leads. This power supply does not require the air flow sensor to operate. The photo below shows an older power supply that just needs 120v to power a cell.

Connect 120 vac to terminals P1 and P2. Check the following outputs with respect to chassis ground.

Terminal P3 will output 8.2k vdc
Terminal P4 will be 4.2k vdc

Since high voltage meters are not common, Honeywell provides the neon lamp as reliable voltage indicator. If the high voltage output falls below spec the neon lamp voltage will drop out.

Shorting P3 or P4 to ground has the same effect as the test button. The short will temporarily cause the neon indicator to go out. By tapping P4 to ground you should be able to draw an arc 1/32". Tapping P3 to ground can produce a larger arc near 3/16". These tests are with out the cells connected, the arc will be twice the length with cells connected.

F300 Quick Parts Swap

If you need to replace your F50F power box and would like a spare pair of cells. For the best value consider buying a new F300E.

All the Parts from a new F300E are fully interchangeable with any prior F50F of the same size. You can swap over the power box, cells, prefilters, and door to your F50F frame. The power box mounts with two screws. The powerbox comes with 120v cord.
