Item N o 11 Spare UV tube
The UV germicidal tube (when fitted) is located on a platform on the inside front wall of the cabinet above the work area.
It is fitted by means of a locking device and relevant ring nuts. The light is emitted at a wavelength of 254nm, which
produces deactivation of proteins and nucleic acid strands, thus sterilizing the work area. Since UV irradiation is harmful
to skin, the operator and the environment around the cabinet must be protected from accidental exposure, and therefore the
UV light is only functional when the window is fully closed. (To set up UV exposure times see relevant section under
“Controller settings”)
The average life time under normal operation is expected to be around 3000 working hours but since the UV
effectiveness reduces with time it is recommended that the UV tube be replaced annually if used regularly (daily) or at a
running time of no more than 2000 hours.
To replace the UV lamp proceed as described below:
1 Raise the motorized front window to the full open position to allow access to the work area.
2 Rotate the ring nuts anticlockwise until they unhook, release them from the tube as shown in Figure 7
3
Rotate the germicidal tube 90º to release it from it’s seating.
4 Release the ring nuts from the germicidal lamp and transfer them to the new lamp.
5 Fit the new lamp by following the procedure in reverse order.
Under certain circumstances, it may be necessary to replace the Lamp starter as well. The starter can be found on the side
of the platform. To replace it, simply rotate it anti-clockwise until it loosens, release it, replace with a new starter and
rotate clockwise until secure.
