! Mercury Burner Replacement
1. The service life of the mercury burner is 300 hours. In order not to
impair the safety of the equipment, replace the burner when it has
been used for 300 hours (USH-103OL, HBO103W/2). The burner
may crack if used beyond the specified life time.
When the end of the burner's service life is near, flickering is likely
to increase. It is therefore recommended to replace the burner
according to the purpose of observation.
* This value assumes light cycles composed of 2 hours of lighting
and 30 minutes of extinction (with the USH-103OL). Do not turn it
on and off at a shorter cycle than the above, for this will shorten the
service life of the burner.
2. Before replacing the burner, wait at least 10 minutes, or until the
burner and lamp housing have cooled down, after turning the burner
off. Before removing the burner, confirm that the main switch is "
(OFF) and unplug the connecting cord from the output connector
of the power supply.
Refer to page 16 for details on replacement procedure.
3. After replacing the burner, reset the hour counter to "000.0" as out-
lined above.
