onds after the flush solenoid valve
closes. During operation, the storage
reservoir floats will: 1) switch the
EASYpure RO into standby mode
(pump off) when the storage reservoir
is full, 2) switch the EASYpure RO
back into water production mode
(pump on) when the reservoir level
drops approximately five inches, and
3) switch off any EASYpure unit con-
nected to the EASYpure RO when the
water level in the EASYpure RO's
storage reservoir is too low to ensure
an adequate water supply to the other
EASYpure unit (this requires the
pump interlock cord to be installed).

The microprocessor tracks operating
time and at pre-selected intervals illu-
minates the “replace filter” light, signi-
fying that the carbon cartridge should
be replaced.

8.

When the reservoir is full and the
EASYpure RO is in standby mode, a
clock is activated which energizes the
EASYpure RO for five minutes every
three hours and fifty-five minutes. This
ensures that water will not stagnate
on the membrane surface. The major-
ity of the water produced during this
five-minute cycle will divert to the
drain.
