Ultrafilter Replacement
The length of your ultrafilter’s life will depend to some
extent on conditions and use in your lab. When you are
unable to completely sanitize your system (i.e. you can no
longer get pyrogen-free water even after sanitizing the
system), replace the ultrafilter as follows:
1. Turn off the EASYpure UV/UF and disconnect it
from the power supply.
2. Depressurize the system by opening the draw-off
valve, allowing water to drain until no more water
flows from the valve.
3. Follow the instructions for ultrafilter installation
found under Ultrafilter Installation, removing the old
ultrafilter in the same way that the instructions
describe removing the “T”.
4. Sanitize the EASYpure UV/UF according to the
instructions on page 24.
UV Lamp Replacement
The ultraviolet lamp requires changing every 90-120 days.
Lamp life will vary according to the number of times the
EASYpure UV/UF unit is turned on and off ( the START/
STOP mode). This estimated lamp life is based on the
EASYpure UV/UF being operated in the RUN mode during
normal working hours (assumed to be 9 hours/day, 5 days/
week) and then placed in the STANDBY mode during off
hours (15 hours/day), weekends and holidays. Since the
lamp turns on 10 minutes/hour during the STANDBY mode,
this amounts to 15 START/STOP cycles per working day. If
the EASYpure UV/UF is cycled between the RUN and
STANDBY modes during the work day, this will result in a
shorter lamp life. Therefore, it is recommended that the
EASYpure UV/UF be left in the RUN position during normal
working hours. Leaving the unit in the STOP mode at night
and on weekends will lengthen UV bulb life but will compro-
mise water quality. Higher rates of bacterial growth, as well
as ionic and organic purity degradation, will occur,
MAINTENANCE AND SERVICING
Note
Some water will drain from the ultrafil-
ter when you disconnect it. Have a
container ready to hold the ultrafilter
and catch the water while it drains.
Water will also drain from the tubing of
the EASYpure UV/UF onto your bench
or floor. To avoid slipping and falling,
clean up all spills.
Warning
Depressurize system prior to opening
cartridge access door.
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.
Note
The UV Solid State Ballast in the
EASYpure UV/UF cabinet has a green
light that will be lit if the lamp is illumi-
nated. Also, an audible sound will alert
you if the lamp is not lit or is
disconnected.
