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."
