CHECKING THE POWER SUPPLY

NOTE:

If the output light remains out with the collector cells removed from the

cabinet, the power supply is defective. Specific problems on the power tray

assembly can be isolated by using a multimeter and high voltage probe to

check the output voltages.

To check the secondary circuit, a high voltage meter is required. See the

section entitled RECOMMENDED SERVICE TOOLS. To check for proper

operation, it is imperative that the procedure be followed as outlined below:

1. Make sure the furnace blower is operating, the control switch is on and

input voltage is 120 volts, 60 Hz.

2. Remove front door assembly panel.

3. Remove power pack access cover.

4. Check the high voltage contact board assembly(s) for damage or carbon

tracking.

The cell contacts should be visually checked for corrosion,

excessive dirt build up, and electrical arc tracking (Carbon path from

stainless steel spring to grounded metal). Clean or replace as required.

5. Make connections from the high voltage probe to the multimeter in

accordance with the operator's manual. The meter should be set for

reading DC voltage on the 20 volt full scale.

6. Attach the high voltage probe ground lead to the cabinet. While

depressing the safety switch lever, touch the ionizer wire support bar

with end of the high voltage probe (Figure 10). The meter reading should

be 6.2 kVDC ± .2 kVDC.

7. If no voltage is measured, remove the first cell and check the second cell.

The meter should read 6.2 kVDC ± .2 kVDC.

8. If proper voltage is measured, the first cell is shorted. Refer to Table 1, on

page 12.
