from back-flowing into the unit.
For Oxygen Input:
• Disconnect the small tubing from the O
²
in port.
• Connect the oxygen source to the O
²
in port with appropriate tubing. You may use the
provided flexible tubing.

Ensure that the air compressor switch is in the OFF position when using an oxygen
source.
For Ambient Air:
• Turn on both air compressor switch and the ozone switch, in that order.

• Turn the power button on – it is located on the back of the unit by the power cord.
• Turn the ozone concentration knob to 100 percent or desired concentration for the given
application.
CAUTION:
If ozone concentration is below 20 percent, the unit will not power up unless
external oxygen is attached. The dial can be adjusted after starting, but avoid dialing up and
down continually, as this action may harm the control board.
• Set the unit timer for the desired application duration.
• The timer can be dialed counterclockwise to allow for an “Always On” function.
• Keep in mind, this function is not recommended for oxygen air.
• At this point, the MP Unit is powered up.
