Operating QT Thunder-24
Following are basic instructions for programming your unit to eliminate odors in an area up to 10,000 cubic
feet when the treated area is unoccupied.
his unit features a programmable timer with up to 6 On/Off setting pairs (12 automatic switch settings).
T
Each setting time can be once a week, every day, every weekday, or only on weekends. The timed
settings combined with a fixed ozone output of 300 mg/hr, allows the user the ability to effectively
deodorize a given area up to 10,000 cu/ft on a scheduled basis when the area is vacant. A manual
override option gives you ozone on demand for a quick clean up.
Determine your Programmed Settings
The time needed to effectively eliminate odors in a given area depends greatly on the size of the room, the level of
odor in the room, temperature and humidity. Our recommendation is that you run the unit for 30 minutes for every
2400 cu/ft of space being treated. You should adjust the unit for shorter run times if you detect an ozone odor after
the unit has been off for a time equal to the time it was in operation. If the odor is still present after the unit has ran
you should adjust the unit to run for longer periods. After the first week of treatment you may have to adjust the
unit to shorter run times as the odor factor should be significantly lower. In the summer months, you may have to
adjust the unit to run for longer intervals, as the humidity levels will decrease ozone output. You should always
allow ample time for ozone levels to dissipate before occupying a treated area. Usually an amount of time equal to
the time the unit was in operation is sufficient. If you need help in determining your programmed settings, please
contact Customer Service at 1-877-64 OZONE.
While smell is not an accurate guide to ozone levels, in levels above .03 ppm ozone has a very strong unpleasant
odor. If you are experiencing a strong odor, headache, dry nose and/or dry throat, you should adjust the run time
for shorter periods or allow a longer period of time before occupying the area to allow the levels to dissipate.
Programming The Timer
The timer used in this unit is basically a programmable switch. At any time you can push the clear cover/switch to
manually turn the unit ON or OFF, unless selected mode is CLK or PGM. You can program up to 12 ON/OFF
events; times when the timer automatically switches the unit ON or OFF (up to 6 ON events and 6 OFF events). An
event can be set to switch at:
any specific time, and day of the week
a specific time every day
a specific time on weekends, or
a specific time on weekends
