Operating Your Air Purifier
On/Speed Control: Rotate the Speed Control knob to set the desired
speed. A setting of zero (0) indicates that the unit is off, one (1) is low speed,
two (2) is medium speed, and three (3) is high speed. The fan speed can be
adjusted at any time.
Ionizer: Press this button to turn 'on' the ionizer. When the ionizer is 'on',
the green light near the button will be illuminated.
Pre-Filter and Filter Timers
This air purifier contains timers that indicate when the pre-filter and filter
should be changed. The timer automatically counts the number of hours that
each filter has been in use. When the pre-filter counter reaches 1400 hours
(approximately three months of use), the pre-filter indicator will be lit to show
that the pre-filter should be changed. When the HEPAtech
reaches 2800 hours (approximately four to six months of use), the HEPAtech
filter indicator will be lit to indicate that the filter should be changed. The exact
life of the pre-filter and filter will depend upon the environment. If necessary,
the filters should be changed more frequently.
To reset the pre-filter or filter timers when one indicator (or both) is
lit:
1. Change the filter and/or pre-filter as described in the Maintenance
section of the manual.
2. To reset the counter to zero hours and turn off the indicator, simply press
and hold the filter reset key for three seconds. If both the pre-filter and filter
indicators are lit, the reset key will first turn off the pre-filter indicator. Then,
you must release the reset key and then press and hold the filter reset key
again for three seconds to turn off the filter indicator.
To reset the pre-filter or filter timers before the indicators are lit:
In some environments, you may want to change the pre-filter or filter more
frequently than indicated by the filter indicators. This procedure allows you to
reset the pre-filter or filter counter before the indicators are lit.
1. Change the filter and/or pre-filter as described in the Maintenance
section of the manual.
2. Now, you must choose which timer you want to reset. Press and hold the
filter reset key (approximately three seconds) until the pre-filter indicator
flashes. Press the reset key again to alternate between the two indicators.
The timer that will be reset is designated by the flashing indicator.
3. Once you have the correct indicator flashing, press and hold the reset key
for three seconds to reset that timer to zero hours. The indicator will stop
flashing when it has been reset. If needed, repeat these steps to reset the
other timer.
