OCA 500/1200/1500 Operation and Maintenance Manual
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.
Machine Status
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.
