Important
Although the HEPA-FLOW™ APS625 is an effective means of
reducing airborne contaminants; it is intended to be used in
conjunction with standard universal precautions, such as the use of
facial respirators, gloves, gowns, and other protective measures.

What the APS625 Does
The HEPA-FLOW™APS625 is an effective defense against viable and nonviable airborne
contaminants such as lint, dust, spores, pollen, bacteria, molds, and other microorganisms. It
combines three methods of air-quality control:
• High-efficiency particulate air (HEPA) filtration.
• Ultraviolet germicidal irradiation (UVGI).
• Room pressurization capability.
Ideal for use in a variety of settings — including Hospital Isolation, Emergency, Bronchoscopy,
and Autopsy Rooms; Nursing Homes, Rehab Centers, Correctional Facilities and Laboratories
— this compact stand-alone unit provides efficient, flexible air filtration and purification.

Where Unit Can Be Installed
The HEPA-FLOW™APS625 is a mobile floor unit. Please see "Equipment Options" in the
Appendix for accessories required in specific applications.
How the Unit Filters and Purifies the Air
The HEPA-FLOW™ APS625 draws room air in through a return air grille at the bottom and
discharges filtered air (supply air) through a grille at the top. This airflow direction cleans the
room air of dust, dirt, and other particles by pulling them down, out of the air and provides
cleaned air at the breathing zone.
As air enters the bottom of the unit, it passes through a
protective grille that prevents objects(pieces of paper,
etc.) from entering the unit and helps assure safety. The
air then passes through a 30% efficient, ASHRAE
antimicrobial filter. This disposable filter, called the pre-
filter, prolongs the life of the finer HEPA filter by
removing large particles from the incoming air.
A blower then forces the air into the unit's upper
chamber, where it is exposed to germicidal ultraviolet
light (253.7nm). Trapped on the inlet side of the HEPA
filter, viable microorganisms are continuously exposed
to this UV radiation, which changes the DNA structure
of the particles and renders them harmless.
Finally, the air passes through the HEPA filter, which is 99.97% efficient in capturing particles
0.3 microns or larger. Particles this size—10,000 times smaller than a human hair and 2,500
times too small to be seen by the unaided human eye—include pollens, lung damaging dust,
bacteria, viruses, and tobacco smoke.
The HEPA filter is firmly sealed to prevent air from leaking around it, assuring that all
processed air has been both radiated and filtered. The sterilized air exits into the room through
the discharge grille at the top of the unit providing cleaned air at the breathing zone.
Important
Although the HEPA-FLOW™ APS625 is an effective means of reducing
airborne contaminants; it is to be used in conjunction with standard
universal precautions, such as the use of facial respirators, gloves,
gowns, and other protective measures.

6. Certificate of Performance
Call [phone] to report any damage during shipment or missing parts.
Room Requirements
The HEPA-FLOW™ APS625 requires a standard 110-volt, 60-Hz, three hole grounded
electrical outlet on a 15-amp (minimum) circuit. (A 220-volt, 50Hz model is also available.)
The unit comes with an UL Listed Hospital Grade Cable (part no. 14-6066).
WARNING: Do not use an adapter with an ungrounded two-hole outlet to
connect this unit. If necessary, call an electrician to update your electrical
plugs and/or circuitry to accommodate the unit.
If the room needs to be pressurized, an opening to air outside the room is also
required. See "Equipment Options" in the Appendix for accessory products
designed for use in pressurizing the room.
Set-Up Procedures
1. The APS625 is a freestanding floor unit that can be rolled easily to the desired
position in the room. The negative pressurization kit can be installed on any of the
different options. See Equipment Options section of Appendix for different types of
units.

Page 9
2. Roll the unit to the desired location. Position the unit close enough to a 110-volt (or,
if appropriate, 220-volt) grounded electrical outlet so that you can plug the unit in
without using an extension cord. Make sure the plug is accessible—the unit will need
to be unplugged monthly for routine maintenance.
Note: To achieve proper airflow, be sure the return-air grille (at the bottom) and the
clean-air discharge grille (at the top) are both unobstructed. There should be a free flow
of air into and out of the unit.
3. Plug one end of the power cord into the plug on the side of the unit. Press the cord
fully into position so that it's firmly seated.
4. Plug the other end of the power cord into the grounded electrical outlet in the room.
Make sure the cord is neatly and safely arranged so that people don't trip on it or
walk over it.
Turning the Unit On
1. Be sure the power cord is plugged into the unit and that the unit is plugged into a
suitable three-hole grounded outlet.
2. Insert the operator's key into the key switch.
3. Turn the key clockwise to LOW or HIGH, depending on the desired operating speed.
The indicator light will come on to show that the unit is operating.
4. Remove the key to prevent unauthorized changes to the unit's operation.
Turning the Unit Off
1. Insert the operator's key into the key switch.
2. Turn the key counterclockwise to OFF. The indicator light will go off to show that the
unit has stopped operating.
3. Remove the key to prevent unauthorized operation of the unit.

Page 10
Adjusting the Low Fan Speed
The following procedure sets the operating speed of the fan when the unit is set to the
LOW setting. The low fan speed adjustment is located inside the unit to prevent
tampering by unauthorized personnel. You'll need the service key to access the low fan
speed control.
WARNING: Because of the danger of putting fingers into the
blower when the pre-filter is removed, only a qualified service
technician should perform this procedure.
NOTE: Never adjust the unit down to 0 Cubic Feet per Minute (CFM). Running the unit
at 0 CFM will damage the motor.
1. With the unit running, use the service key to remove the front panel, as described
under "Monthly Maintenance" in the next section.
2. Remove the pre-filter as described under "Monthly Maintenance" in the next chapter.
3. Turn the low fan speed control to the desired CFM setting. Keep in mind that the
higher the setting, the higher the noise level produced while the unit operates at
LOW. Consideration in setting low speed should be given to the desired ACH and
negative pressure (if used). The basic formula for determining estimated ACH
(perfect mixing) is:
CFM
ACH = Room Volume x 60
4. Replace the pre-filter and front panel.
Note: At the HIGH setting, the unit always operates at maximum capacity and
maximum fan speed. The procedure described above adjusts only the fan speed when
the unit operates at LOW.
