Changing lamp assembly
1 Use a Philips screwdriver to detach the end plate by removing
one and loosening the other of the two holding screws on the
lamp housing to be removed.
2 Slide the lamp housing off the filter housing.
3 Detach the end plate, as in step 1 above, from the lamp housing
to be fitted to the optical unit.
4 Slide the lamp housing onto the filter housing. The lamp and
signal cables should be on the same side. As you slide the lamp
housing into position, depress the two pressure pads on the
filter housing in sequence to facilitate the installation.
5 Refit the lamp housing end plate.
6 Slide the lamp housing firmly into place. There will be a faint
click when the housing is positioned correctly. The Hg lamp
housing can take up two positions, one for 280 nm, marked
by on the filter housing, and the other marked by for
all other wavelengths. The Zn lamp housing has only one
position.
7 Set the wavelength to be used by selecting lamp position
(indicated by a dot on the lamp housing) in combination with
the appropriate filter, i.e. the dot on the lamp housing should be
adjacent to the symbol on the filter housing corresponding to
the symbol on the filter wheel for the filter to be used. A click
will indicate that the filter is in position.
Note: The wavelength and the flow cell type should also be entered
in the Questions menu in UNICORN.
Filter change
The Hg optics with 254 and 280 nm filters and the Zn optics with
the 214 nm filter are delivered with filters installed. If other filters
are to be used, install the new filters as described in 2.10 Installing
optical filters (optional).
WARNING! The module uses high intensity ultra-violet light. Do
not remove the UV lamp while the monitor is running.
Before changing a defective lamp, ensure that the lamp cable is
disconnected from the monitor to prevent injury to eyes.
If the mercury lamp is broken, make sure that all mercury is
removed and disposed of according to national and local
environmental regulations.
