First Time Setup
Turn Plug OCA unit into appropriate power source. The power button will flash white. Press
power button. The unit will perform an internal safety/maintenance check. If there are any
safety or maintenance issues, one or more of the HEPA, UVGI or PREFILTER indicators will turn
red and the housing light for that area will flash blue. If this occurs, consult the Troubleshooting
section of this manual.
You will then access the Enter Guided Setup screen.
Press OK to enter room size and room ID information, or
select Do this later to bypass setup. (Note: if the Guided
Setup is not completed, machine cannot display Air
Changes per Hour).
Enter Units prompts to select either US Standard (ft., in.)
or Metric (M,cm ). You can also enter “Go Back” to return
to the previous menu.
Enter Room Size lets you either enter the dimensions of
the room the unit will be in, the volume of the room (if
known), or select I Don’t Know. I Don’t Know sets the
unit at its highest output.
If DIMENSIONS or VOLUME is chosen, use the UP/DOWN
arrows to increase or decrease the highlighted
dimension or room size. Press OK to enter and when
complete.

In addition to the CFM/CMM reading, this menu also shows you the current number of Air
Changes per Hour (ACH), based on your fan settings and the room size you have entered. For
instance, if you had a 2500 cubic foot room and your fan was set at 500cfm, your ACH would be
12 (60 minutes divided by 2500/500). The example above shows an ACH of ???; this would be
the reading if you skipped the Guided Setup or entered “I Don’t Know” in the Enter Room Size
menu.
6
Enter Room ID allows you to assign a 3 digit
alpha-numeric code to the space the unit is located in.
This is helpful if you plan to move it frequently. Use the
UP/DOWN arrows to change; OK to select.
The unit will then go into operational mode. The display
will show Cubic Feet per Minute (CFM) or Cubic Meters
per Minute (CMM). This can be adjusted using the
UP/DOWN arrows.
Press OK to return to the Main Menu. Select Activate
Safety Lock, then press OK again to lock the current
settings. This will prevent tampering. Press OK twice
again to unlock and adjust settings.
In addition to the above, from the Main Menu there is
also an option for Passcode Setup. This feature is
reserved for administrators or authorized users to
provide additional security. Contact your administrator
for more information.
Normal Operations
Now that Guided Setup has been completed, your unit will return to those settings each time it
is turned on. To change these settings, press OK and toggle to Enter Setup Mode. Make desired
changes and select Go Back to return to normal operating status. The machine must be
operated with a HEPA and pleated PreFilter in place.

HEPA Filtration
The HEPA filter purifies the air and will gradually become loaded with sub-micron particulates.
Even when the HEPA filter is fully loaded, the filter is still removing particulates from the air at
the rated efficiency, yet at a reduced airflow. This will affect the ability of the machine to
provide positive or negative pressure within the containment. We recommend changing the
HEPA filter after no more than 365 days of operation.
UV Germicidal Lights
UVGI lights are installed in the compartment below the HEPA filter. The air passing by the UVGI
lights is sterilized and the bio-contaminants captured on the HEPA are killed or deactivated. To
maintain the full effectiveness of the UV Germicidal we recommend replacing the lights after
365 days of operation.
PreFilter
Near the bottom of the machine and right above the air intake grate is an access door for the
pleated PreFilter. The PreFilter is rated Minimum Efficiency Reporting Value (MERV) 11, and is
designed to remove dust, pollen, mold spores and other small particles from the air before it
passes through the HEPA filter. This will significantly extend the usable lifetime of the HEPA
filter, which is much more costly to replace. We recommend changing the PreFilter after no
more than 90 days of operation.

Machine Information Check
Information about your OCA machine can be reached
from the Main Menu by pressing OK; then using the
UP/DOWN arrows and selecting Show Machine Info. The
display will show Model Number, Serial Number,
Software Revision and Date of Manufacture. Press OK to
return, then UP/DOWN to Go Back to Main Menu.
Machine Status
You can check the status of the unit at any time from the
Main Menu by pressing OK; then using the UP/DOWN
arrows and selecting Machine Status. This will show the
number of days the unit has been in operation, as well as
the number of days of use for the HEPA filter, UV lamps
and PreFilter. The HEPA filter and UV bulbs each have a
usage life span of 365 days before replacement is
required; the PreFilter has a 90 day life span. The
example shows that the HEPA filter has been in use for
372 days, and therefore should be replaced.

Maintenance & Troubleshooting
Status Monitoring
The OCA Series machines continuously monitor the
UVGI, HEPA and PreFilter systems for failures, errors and
scheduled replacement times. If any of these systems
require attention, the Display screen will show a “Check
Status” advisory and “Warning” triangle symbol. At the
same time, the panel status indicator LEDs and the
lights in the corresponding areas on the front casing will
alert the user and describe the issue. The table below
lists the errors in order of their priority. If more than one
error occurs simultaneously, the display will show the
higher priority error first; then move on to the next when
the first one is resolved.

HEPA Filter Installation/Replacement
To replace the HEPA filter, unplug the machine and remove the top grill. You will see 4 filter
tabs holding the HEPA filter in place. These tabs are secured with 1/4-20 Nylock nuts, which
require a 7/16” wrench or socket. Remove all 4 filter tab retaining nuts and remove the filter
tabs and set aside. Lift HEPA filter out. Replace with new HEPA filter and replace the filter tabs.
Be sure to tighten the locknuts securely to ensure a tight seal with the filter gasket. ALWAYS
TREAT THE USED HEPA FILTER AS HAZMAT AND PROCESS IT ACCORDING TO YOUR
ESTABLISHED HAZMAT PROCEDURES.
Replacing UV Germicidal lights
If the UVGI indicator light turns red, you will need to access the lights to replace the bulbs. We
recommend changing all bulbs simultaneously. WARNING: Unplug the unit before opening
UVGI light compartment. Remove the 2 screws on each side of the UVGI compartment and
gently slide the drawer forward to access the bulbs. The lights are each held in with (2) clips;
gently pull the light out of the two U-clips, then disconnect the 4-pin connector. Replace the 4
bulbs and return the drawer to its original position. Reinstall the light compartment door. Plug
in and turn the unit back on; if the UVGI indicator is still red, the problem could be one or more
of the ballasts. Call Omni CleanAir Technical Support for additional assistance
PreFilter Replacement
The pleated filter should be changed when it becomes loaded with dust. To change the filter,
turn off the machine, remove the 2 screws on each side of the PreFilter compartment and
remove the compartment cover. Remove the dirty filter and replace; then reinstall the cover.
Resetting the Machine Status
After completing the above required maintenance, you
will need to reset the Machine Status for the affected
item. From the Main Menu press OK; then use the
UP/DOWN arrows to select the Maintenance Menu.
Scroll to the desired reset and press OK. This will turn the
status back to day 0 for that item. The sample screen
shows resetting the UV Bulb age. DO NOT reset other
fields; only the one you have performed maintenance/
replacement on.
