Lamp Replacement
Note:
Since the lamp reaches a very high temperature
during units operation replacement of the lamp
should be done at least one hour after the power
has been turned off. (to allow the lamp to cool off.)
Installing the new lamp, make sure not to touch the
lamp (bulb) replace the lamp by holding its reflector
2.
[Use original replacement only.]
DANGER ! –– Never turn the power on without the
lamp to avoid electric-shock or damage of the
devices since the stabilizer generates high voltages
at its start.
Since small amounts of UV-Radiation are emitted
from an opening between the duct cover and the
lamp housing, it is recommended to place the LENS
CAP on the opening during servicing to avoid eye
and skin exposure.
Note: Please obtain a lens cap before servicing a
models XV-Z90E/XV-Z91E that is received
without one.
