Assigning Location Id; Lock/Unlock Settings; Settings Review; Normal Operations - Omni OCA 500 Operation And Maintenance Manual

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.
