OPERATOR SERVICING
The following servicing instructions are intended for limited maintenance of
the lamp. Do not perform any servicing other than that contained in these
instructions. Return the lamp to the factory for other maintenance not covered in
this section.
HOUSING AND MAGNIFIER LENS MAINTENANCE
The polycarbonate lamp housing protects the internal parts. Immediately clean
spills from the housing and magnifier lens with water and a mild detergent
and wipe dry with a soft cloth. Do not allow any liquids to leak into electrical
components. Periodically clean the lens with a glass cleaner and a soft cloth.
TUBE AND REFLECTOR MAINTENANCE
T
o clean the tubes and/or reflector, see the ‘’TUBE REPLACEMENT’’ section.
Using a soft cloth, the reflector may be cleaned with a glass cleaner, while the
tubes may be cleaned with a mild detergent solution. Wipe dry with a soft cloth.
TUBE REPLACEMENT
When replacing a tube, unplug the lamp from its power source before proceeding.
1. Lay the lamp housing on a flat, level surface with the tubes facing up.
2. Gently rotate each tube (one at a time) until the metal contacts at each end
line up with the small rectangular openings. The tube may now be easily
removed from its sockets.
3. Install the new tube by first aligning the contacts at the end of each tube with
the small rectangular openings at each end of the sockets.
4. Turn one tube at a time gently to rotate about 90° for the tube to be locked
into place by the “
Safety Slots.
”
Safety Slots
ensure proper contact by aligning
each tube, provide insulation and protects from electrical shock.
5. If installation of the new tube fails to yield correct lamp operation, check to
make sure the two pins at each end of the tube are properly connected with
the two copper contacts in each socket.
NOTE
: The tubes in all QZ-Series lamps are wired in series. Therefore, if one
tube fails the other tube of the same wavelength will not light, even though it
may be in good operating condition.
WARNING
To avoid the risk of electrical shock, always unplug the lamp from its
power source before cleaning or servicing.
