The symbols are presented on the screen below the “status bar”. The text
indicates the current operation and the stage reached within that operation. This text
will alternate with any warning or advisory messages that may be present.

it indicates it is powered.
5.3.2 Explanation of displayed functions
Each time you press the Function button, “
▼”, at the top right hand edge of
the screen you will be able to display information relating to the performance of the
unit. The information will be in the form of numbers and text and displayed on the
“status bar”. This information may be required by your Healthcare provider when
diagnosing a possible fault.
There are 6 selectable function values, an explanation of each is given in the table
below.
Displayed Function Explanation
Flow Rate This is the volume of permeate the unit is producing
and is measured in “
gallons/min ”
Permeate Quality This value indicates the quality of the permeate
water and is measured in
microsiemens/cm or
µS/cm .
Temperature This tells you the temperature of the water being
produced and is displayed in, “
0
F” .
Pump Pressure The unit contains a pump to process the water and
this displays the pressure the pump is running at in
“psi”.
Feed Quality
If enabled the unit will constantly measure the quality
of the incoming water supply and display the reading
in
microsiemens/cm or µS/cm .
Salt Rejection Again if enabled the “Salt Rejection ” compares the
quality of the purified water to the feed water and
expresses it as a “%”. This will be used by your
Healthcare provider to check the performance of the
unit.
Note:
When diagnosing a fault on the unit your Healthcare provider may ask you for some of the readings above.
Make sure that you are familiar with the operation of the
“Function” button and how to obtain the
information.
Always refer to
Section 9.1 “Troubleshooting guide” when speaking to your Healthcare provider
regarding any fault.
Warning:
It is recommended that the key used to select CLEAN/SERVICE positions is removed to prevent anyone
from accidentally switching the unit to the wrong mode during use. The key is only required for use
during either Heat disinfection or Chemical clean.
Having the key switch in the wrong position could interrupt dialysis or the cleaning/disinfection of the unit.
