OS3 DM20036 (3−2018)
HOW THE MACHINE WORKS
The Orbio os3 is an on−site generator that
produces cleaning and antimicrobial solutions for
institutional and commercial use. The os3 uses
electrolysis to convert water and salt into low
concentrations of sodium hydroxide (NaOH) for
cleaning and hypochlorous acid (HOCL) for
antimicrobial applications. These solutions are
diluted through the os3 dispenser as ready to use
products. No additional dilution is required.
NOTE: Store MultiSurface Cleaner and MultiMicro
200 Solution in a room/location where the
temperature is between 50−110°F (10−43°C).
WHILE OPERATING THE MACHINE
Periodically check the display panel indicators to
ensure there are no service alerts that need to be
cleared. Conditions must be cleared before the
os3 can be used again. Avoid running the system
completely out of salt. Add water softener salt to
the reservoir on a routine basis as the salt supply
is consumed. When the add salt indicator is
displayed the machine will stop until salt is added.
Refer to the Filling the Salt Reservoir section of
this manual.
NOTE: If water supply is turned off, unplug
machine until water supply is restored, then plug
machine in.
The operator is responsible for ensuring that the
solutions are at the proper pH and concentration
levels. Refer to TESTING THE ANITMICROBIAL
SOLUTION and TESTING THE CLEANING
SOLUTION in the Maintenance section of this
manual for proper testing procedures.
CLEANING SOLUTION
(top positions indicated in blue)
Multi
CLEANER
Multi 200 Micro
MultiSurface Cleaner is the cleaning solution
produced by the os3. MultiSurface Cleaner will
clean most soiled or dirty surfaces (wool, nylon
and polyester carpeting, glass, stainless steel,
other metal, ceramic, laminate, painted surfaces,
and other non−porous surfaces), but is not
recommended for cleaning heavy petroleum
based oils and greases.
NOTE: Always check carpet manufacturer
specifications for color stability and shrinkage
properties before using a water−based solution on
carpeting.
Do not dilute MultiSurface cleaning solution with
water. Water will diminish the cleaning
effectiveness. MultiSurface cleaner is ready to
use after dispensing.
FOR SAFETY: Do not mix MultiSurface
cleaning solution with conventional cleaning
chemicals. Do not drink. Refer the SDS (Safety
Data Sheet) for additional safety information
and precautions.
MultiSurface cleaner will remain effective for 30
days or more when stored in a clean, sealed
container. Test the cleaning solution to verify the
pH level is at the correct level if the solution has
been stored for longer than 30 days. Refer to the
Testing the Cleaning Solution in MAINTENANCE
for additional testing information.

EN OPERATION

ANTIMICROBIAL SOLUTION
(bottom positions indicated in yellow)
Multi
CLEANER
Multi 200 Micro
MultiMicro is the antimicrobial solution generated
by the os3. The os3 dilutes this solution and
dispenses MultiMicro 200, the ready to use form
containing 200 ppm available chlorine. MultiMicro
200 is an effective disinfecting and sanitizing
solution. Do not dilute MultiMicro 200 with water.
The solution is ready to use after being dispensed
from the Orbio dispenser.
MultiMicro 200 stored in a spray bottle or sealed
container is effective for up to 7 days. Discard
expired solution.
MultiMicro Concentrate has a stability of 30 days.
To ensure proper concentration levels, the
MultiMicro tank must be evacuated at least every
30 days. Evacuate the MultiMicro Concentrate
using the MultiMicro 200 bucket fill position. Drain
until the Wait to Dispense indicator displays.
Dispose the solution according to local waste and
disposal regulations.
FOR SAFETY: Do not mix MultiMicro 200 with
ammonia or acid which will produce chlorine
gas. Do not mix with other cleaning products.
Refer to the SDS (Safety Data Sheet) for
additional safety information and precautions.
NOTE: For application information and
antimicrobial claims, refer to the use directions
detailed on the os3 generator label.
OPERATING THE ORBIO DISPENSER
The Orbio os3 and satellite systems are equipped
with a four position dispenser.
FOR SAFETY: Do not operate machine unless
operator’s manual is read and understood. Do
not drink. Refer to SDS (Safety Data Sheet) for
additional safety information and precautions.
