Lamp
Reflector
Sincesmallamounts ofUV-radiation areemittedfrom
an opening between the exhaust fans, it is recom-
mended to place the cap of the optional lens on the
opening during servicing to avoid eye and skin ex-
posure (Fig. 1).
Note: Please obtain a lens cap before servicing a
model XG-V10XE that is received without
one.
Figure 1.
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.
UV-RADIATION PRECAUTION (Continued)
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

3. Do not operate for more than 2 hours with the
enclosure removed.
UV-Radiation and Medium Pressure
Lamp Precautions
1. Be sure to disconnect the AC plug when replacing
the lamp.
2. Allow one hour for the unit to cool down before
servicing.
3. Replace only with same type lamp. Type
CLMPF0064DE01/02 or BQC-XGV10WU/1 rated
100V/200W.
4. Thelamp emits smallamountsofUV-Radiation, avoid
direct-eye contact.
5. The medium pressure lamp involves a risk of
explosion. Be sure to follow installation instructions
described below and handle the lamp with care.
