Function
The Whole House HEPA system is comprised of a ventilator, speed selection
switch, 3 stages of filtration and the cabinet enclosure system. The ventilator
pulls air through the pre-filter and pushes the same air threw the impregnat-
ed carbon pad for odor control and finally the last stage of filtration is the HEPA
filter which removes 99.97% of particles 0.3µm in size.
Operation Mode Options
The unit features two speeds of operation for your convenience. The speed
selection switch is located on the front of the motor assembly. At lowest speed
the unit will provide 220 CFM of clean air while at highest speed, the unit will
provide 300 CFM of clean air. It is recommended that the unit be operated on
highest speed at all times to maximize the benefits of the HEPA filtration
system. If for some reason the filtration needs are not as important then one
might operate the unit at low speed.
An access door is provided at the front of the unit
to permit access to the filters and speed selection
switch. Opening the latch on the right side of the
unit will permit the door to swing open. A safety
door interlock switch cuts the power to the motors
for your safety. If needed the door can be removed
from the cabinet hinges by holding the top part of
the door with one hand and gently taping on the
bottom edge of the door with the other hand to release the door from its
hinges.
Recommended Operation
The return plenum mount model operates in conjunction with your forced air
heating/cooling system. A forced air distribution system continuously
circulates the same air inside your home. The whole house HEPA filtration
system operates on the principal of bypass filtration, which means that a
portion of the air being returned into the furnace is filtered on each pass. Over
time all the air in the home gets cleaned. It is recommended that the furnace
blower be in operation whenever the filtration system is in operation.
For stand-alone attic installation, the HEPA filtration system must be
operated continuously whenever a part of all the system is located in an
unconditionned space to avoid condensation in the ductwork below freezing
(32°F ,0°C)
Maintenance of the unit should be performed at regular interval to keep the
benefits of the HEPA filtration unit.
