BYPASS HEPA / BYPASS HEPA PLUS INSTALLATION & OPERATION MANUAL

OPERATION

The unit has multi-stage filtration, a

ventilator, and a cabinet enclosure system.

SEQUENCE OF OPERATION

1. Air passes through a reflection chamber

where germicidal UV light shines. (Bypass

HEPA Plus only.)

2. PCO (Photocatalytic Oxidation) filter.

(Bypass HEPA Plus only.)

3. The air then passes through a pleated

MERV 8 pre-filter that captures large

airborne particulates such as dust, pollen,

and mold.

4. Next, the air passes through an

impregnated carbon pad for odor control.

This pad helps traps airborne chemicals

produced from household cleaners,

paints, solvents, and VOCs. Carbon also

helps trap cooking and tobacco smoke.

5. In the last stage of treatment, smaller

particles then pass through a long-life,

99.97% HEPA media filter, capturing

particles of 0.3 microns (1/84,000 of an

inch).

WARNING

Electric Shock Hazard.

Can cause injury or death.

Electrical wiring of the unit to the

HVAC system should be done by a

licensed HVAC technician or

electrical installer.

ACCESS

An access door is provided at the front

of the unit to permit access to the filters.

Opening the latch on the right side of the

unit will allow the door to swing open. A

safety door interlock switch cuts the power

to the motors for your safety. To remove the

door from the cabinet hinges, lift the door

with two hands.
