Operation Periods
MediQA Operation Periods
Period
Explanation
Standby
The MediQA can be set to “POWER ON STANDBY” for occasions when there
are long periods (typically days during shut down periods) without use. In
standby mode the MediQA performs 10 minutes of operation in every 2
hours. The duration and interval are user settable. This enables water to be
circulated through the MediQA and distribution loop, in order to maintain
water quality.
Supply
Supply is when the RO begins providing water to the loop for use with the
Dialysis machines. This is the process the RO will be in for a majority of its
usage. Can be operated in continuous or a set schedule.
Flush
Before the MediQA provides water to the loop for dialysis use, the system
goes through a flush. This isolates the water from the loop and dumps all of
the water down the drain for a preset time.
Rinse
After the flush cycle is completed, the RO will go into a rinse. During rinse the
unit continues to run the pumps at a high pressure. Water is flushed down
the drain similar to the flush of the membranes.
Refresh
Loop has exceeded the temperature set point and is refreshing the water to
lower the temperature.
RO Heat Disinfect
The MediQA is capable of a heat disinfection of its plumbing and membranes.
During the heat disinfection process the RO circulates water within itself at
185˚F.
Temp Hold
Once the temperature is reached in the RO Heat Disinfect period, the water is
circulated for a set period. Hold time is user settable, see Section 13.1 for
default.
