Burner Service Life
USH-103OL : 300 hours
This value assumes light cycles composed of 2 hours of
lighting and 30 minutes of extinction. Do not turn it on and
off at a shorter cycle than the above, for this will shorten
the service life of the burner.
After replacing the burner, reset the hour counter of
the power supply unit to "0.0."
