Nanopure Life Science (UV/UF)
Warning This unit is equipped with an ultraviolet lamp. Ultraviolet
radiation is harmful to the eyes and skin. Do not attempt to observe the
lamp directly.
s
Note The Nanopure display will read "Check UV Lamp" when the lamp is
burned out or disconnected.
Note The display will periodically show a reminder to change the lamp.
This is a reminder only and does not necessarily mean the UV lamp is no
longer functioning.
s
Note The UV lamp contains mercury. If broken or no longer needed, do
not dispose of the UV lamp in the trash. Recycle or dispose of the UV
lamp as hazardous waste.
The ultraviolet lamp requires periodic replacement. Lamp life will vary
according to the number of times the Nanopure is turned on and off (the
START/STOP mode). Lamp life is based on the Nanopure 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 Nanopure is
cycled between the normal and Standby modes during the workday, this
will result in a shorter lamp life. Therefore, it is recommended that the
Nanopure be left in the normal recirculating mode during regular working
hours. To replace the UV lamp:
1. Turn the Nanopure OFF and disconnect power cord from unit.
2. Access the left side of the unit by unlatching the screw securing the
door with a flathead screwdriver. Unlatch and open the door. The UV
lamp will be installed vertically.
3. Remove the black cap by sliding it off the UV chamber. Disconnect
and remove old UV lamp and dispose of it in the proper manner (see
Note).
4. Remove the UV lamp from its packaging. DO NOT TOUCH THE
GLASS PORTION OF THE LAMP! It is recommended that lint-free
gloves be worn when handling the lamp. The glass portion must be free
of fingerprints, perspiration, etc. Even a light coating of perspiration
will reduce the effectiveness of the lamp. If the glass portion of the
lamp is touched, clean it with a damp, lint-free cloth: use isopropyl
alcohol as required.
