Operational Modes

Note
Do not turn off the EASYpure UV/UF
during non-work hours. Doing so will
allow bacterial growth and other con-
tamination of the water in the system.
As a result, the system will require a
lengthy rinse-up period at the begin-
ning of the work day to achieve high-
quality product water.

Run Mode

Since not all qualities of permissible feedwater will reach
maximum resistivity after one pass through the unitʼs car-
tridges (especially as the cartridges near exhaustion), the
EASYpure UV/UF has two operational modes.
In the run mode, the UV lamp shines continuously and the
pump continuously recirculates water through the cartridg-
es, the UV chamber and the ultrafilter. It is recommended
that the EASYpure UV/UF be left in the run mode during
the day. In the run mode, the purity meter display indicates
the resistivity of the water available for draw off.

Standby Mode

In Standby Mode, the UV lamp shines and the pump runs
for ten minutes out of every hour (i.e 10 minutes on, 50
minutes off). This will allow the unit to produce high quality
water quickly upon being placed in the run mode. It is rec-
ommended that the EASYpure UV/UF be placed in the
Standby mode during non-work hours.

Automatic Flush

In both the run and Standby modes, the EASYpure UV/UF
will initiate a one minute automatic flush of the ultrafilter
once every twenty-four hours of operation. This prevents
bacterial buildup on the ultrafilter. A solid-state timer in the
EASYpure UV/UF counts the hours power is applied to the
unit. When the timer reaches twenty-four hours, the
EASYpure UV/UF initiates a one minute flush, the Automat-
ic Flush LED is illuminated. The timer will reset to zero
when the one minute automatic flush is completed.
