2MEDIQA OPERATION PERIODS
2.1 Operation Descriptions
MediQA Operation Periods
Period
Explanation
Standby
When the MediQA is not scheduled to be on and in TIMER mode, the system
will be in Standby. The MediQA can also be set to “POWER ON STANDBY” for
occasions when there are long periods without use. In standby mode the
MediQA operates for 10 minutes every 2 hours, these values are user
settable. This enables water to be circulated through the MediQA and
distribution loop, in order to maintain water quality.
System OFF
System operation has been switched OFF via the button on the touch screen.
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.
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.
Refresh (MSP
Only)
Loop has exceeded the LOOP OVER TEMP WARNING set-point and is
refreshing the water to lower the temperature.
Clean Recirc
During the recirculation phase of the chemical clean process, all of the water
is redirected back into the MediQA tank. RECIRC PERIOD is user settable.
Clean
The MediQA is equipped with the ability to perform a chemical cleaning of
itself once chemicals have been added in the tank. This mode is also
displayed after Clean Recirc, when the Tank drains completely then refills.
Clean Rinse
After the clean (tank drain) is completed, the RO will go into a clean rinse to
purge the chemicals from the system.
RO Heat Disinfect
The MediQA is capable of heat disinfecting itself. 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 PERIOD is user settable.
Cool Down RO Heat Disinfect enters this mode to cool down break tank and membranes
at the end of the Temp Hold cycle. Cool down temperature is user settable.
The MediQA returns to standby after the cool down temp is reached.
Heatsan Fill
The MediQA has been called on to provide water to the Heatsan.
Loop Heatsan
Heatsan unit is performing a heat disinfection by cycling hot water through
the loop. MediQA locked out from operating. RO turns on during Cool Down
Period of Heatsan.
Override
HMI override key switch is turned, the system goes into continuous mode.
Remote ON
The MediQA is in slave mode and the master MediQA is telling it to operate.
Emergency Stop
System operation has been halted via the Emergency Stop button on the
control panel. Alarm is generated on the touch screen. To Reset, pull the E-
Stop out and clear the alarm from the Main Menu screen.
