Instruction manual
1. Turn off the Barnstead 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 Barnstead TII is turned on and off.
Lamp life is based on the Barnstead 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 Barnstead 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
Barnstead 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.
