Operation
Maintenance
1. Make sure that the unit is plugged into a grounded outflow (120 Volt, 60 Hz).
2. For optimum performance, the HEPA system should operate when the indoor air handler/furnace blower is on.
3. For model 2500HV & 4000HV: Turn the unit on by pressing the on/off switch to the ‘1’ position. The switch
should light up when the unit is on.
For models 6000V, 6500, 8500 & 10000: Turn the unit on by rotating the variable speed dial clockwise. The
unit starts in High speed, turn all the way clockwise for low speed.
4. For model 2500HV & 4000HV: To turn the unit off, press the on/off switch to the ‘0’ position. The switch light
should turn off when the unit is off.
For models 6000V, 6500, 8500 & 10000: To turn the unit off, rotate the variable speed dial counter-clock-
wise until you feel or hear it click into the ‘off’ position
Proper care and maintenance of your HEPA system
will ensure years of service. The unit must be turned
off during service/maintenance or when filters are
being changed.
It is recommended that gloves and a filtered
breathing mask be worn during filter replacement.
Filter Change Schedule
Note: Note: Failure to properly maintain your HEPA
system will decrease the efficiency and air flow.
Pre-Filter: 3 to 4 months*
HEPA Filter: 2 to 5 years
Inner Carbon Filter: 6 months
Optional Carbon Canister: 12 months
* Foam pre-filters (4000HV & 6000V) can be washed
and reused
NOTE: Filter life is based on average air content. Some
filters may need to be changed more often due to higher
amounts of dust, humidity, or chemicals found in your
ambient air. Additionally, people who are more sensitive
to these airborne contaminates may desire more frequent
filter changes.
Filter Changing Guidelines
Pre-Filter:
Dust and other large particles will collect on the pre-fil-
ter over time. The color of the filter will change as par-
ticulates build up on the pre-filter. Change the pre-fil-
ter when you can see the particulate build up start to
clog up the pre-filter.
HEPA Filter:
As the HEPA filter captures particulates, it will darken
over time. Replace the HEPA filter when it darkens to
the level seen in example D.
Inner Carbon Filter:
The inner carbon filter will rarely look used. This filter
captures odors and gasses, yet the filter’s appearance
will not change. When this filter has reached it’s maxi-
mum adsorbancy of odors and gasses, it will no longer
work. Replace this filter when it no longer seems to
capture odors, or every 3 months (12 months for
optional Carbon Canister), which ever occurs first.
