3. General Operating Information
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
impregnated 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 ,O’C)
