Display and Monitoring Panel
First Time Setup
Plug OCA unit into appropriate power source. The power button will flash green.
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 all steps in the Guided
Setup are not completed, machine cannot
display Air Changes per Hour for the room in
which it is operating)
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 gives you the option to
either enter the dimensions of the room the
unit will be in, the volume of the room (if
known), or “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. The display will then
advance to the next selection. Press OK when
complete.

5
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, 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 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.
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. We
recommend replacing the PreFilter frequently to extend the life of the HEPA.
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.
UV Germicidal Irradiation

6
UVGI bulbs are installed in the compartment below the HEPA filter. The air passing by the
UVGI bulbs is sterilized and the bio-contaminants captured on the HEPA are killed or
deactivated. To maintain the full effectiveness of the UV Germicidal Irradiation we
recommend replacing the bulbs after 8000 hours 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.
Maintenance and Troubleshooting
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 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 list
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 Bulbs
If the UVGI indicator light turns red, then you will need to access the bulbs to check the
operation and/or 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 bulbs 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.
Additional Troubleshooting
