Operation
Maintenance
1.
Make sure that the unit is plugged into a grounded outlet (120 Volt, 60 Hz).
2.
For optimum performance, the HEPA system should operate when the indoor air handler/furnace blower is
on. An optional air handler/furnace blower interlock kit can be ordered for ‘cycled’ operation. (see
Replacement Parts)
3.
Turn the unit on by pressing the on/off switch to the ‘1’ position. The switch should light up when the unit is
on.
4.
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.
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:
Failure to properly maintain your HEPA system
will decrease the efficiency and air flow.
For enhanced odor control, the Coconut Shell Carbon
Canister provides up to one year of odor capture.
Carbon Pre-Filter:
12 months
HEPA Filter:
2 to 5 years
Inner Charcoal Filter:
3 months
Optional Coconut Shell Carbon Canister:
1 year
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 air borne contaminates may desire more fre-
quent filter changes.
Filter Changing Guidelines
Carbon Pre-Filter:
Dust and other large particles will collect on the car-
bon pre-filter over time. The color of the filter will
change as particulates build up on the carbon pre-filter.
Change the carbon pre-filter when you can see the par-
ticulate build up start to clog up the carbon 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 Charcoal Filter:
The inner charcoal filter will rarely look used. This fil-
ter captures odors and gasses, yet the filter’s appear-
ance will not change. When this filter has reached
it’s maximum adsorbancy of odors and gasses, it will
no longer work. Replace this filter when it no longer
seems to capture odors, at least every 3 months,
whichever occurs first.
