1. Turn off the TII and disconnect it from the power supply.
2. Pull out the fuse drawer located in the power entry module.
3. Remove old fuses and replace with fuses of the same type and rating.
(See Replacement Parts section.)
4. Replace fuse drawer.
5. Reconnect the unit to the power supply.
6. Operate normally.
The ultraviolet lamp requires periodic replacement. Lamp life will vary
according to the number of times the Thermo Scientific TII is turned on
and off. Lamp life is based on the Thermo Scientific TII being operated in
the normal recirculating mode during regular working hours and then
placed in the Standby mode during off hours. Every fourth time the pump
goes on in the Standby mode, the UV light will go on. If the Thermo
Scientific TII is cycled between the RUN and STANDBY modes during
the workday, this will result in a shorter lamp life. Therefore, it is
recommended that the Thermo Scientific TII be left in the normal RUN
mode during regular working hours.
To replace the UV lamp, see “UV Lamp Installation” procedure in this
manual.
Note
When lamp is burned out or disconnected, the System Alarm LED
will illuminate. Press MENU and scroll to System Alarm for details.

Procedures to reset all routine timers follow.
These timers record service time to ensure the reliability and to reduce the
risk of bacterial contamination. The Prefilter, MPS, Carbon, Membrane
and Cartridge Pack Timers must all be reset prior to initial operation and
after cartridge replacement. See “Routine Care Alerts” for more details.
