Once the Transfer Indicator Light flashes, the concentrate is ready to be tested. This test is done using
a
Hydrometer
, which measures the density of the acid concentrate. The resultant value is called the
“Specific Gravity.” The Specific Gravity is measured to verify that the concentrate has been properly
mixed.

To determine a Specific Gravity reading:
1.
Prepare the hydrometer and the Hydrometer cylinder.
•
Check the hydrometer for cracks. Do not use a cracked Hydrometer.
•
Always handle the hydrometer with care. Always hold it vertically by the top, as finger marks
lower down can affect the accuracy of the instrument.
•
The hydrometer should never be held by the stem horizontally.
•
Rinse the hydrometer and the Hydrometer cylinder separately with purified water before
checking solution for Specific Gravity. The purified water source must meet
ANSI/AAMI
or
ISO
standards for dialysis currently
ANSI/AAMI RD62
, or
ISO 13959
.
•
Once the hydrometer
is clean, place it
onto a clean area.

Remove Transfer Hose from the top of the tank (Figure 9) and connect the Transfer Hose to
the Transfer Nozzle (Figure 10).
3.
Hold the Transfer Nozzle and make
sure the Ball Valve on the Transfer
Nozzle is CLOSED (Figure 11).

Lower the locking levers of the Transfer Hose
Connector and lift up on the Transfer Hose to remove
from the side of the Unit.
Transfer Hose
With the Transfer Hose Connector locking levers
open, place the connector onto the end of the
Transfer Nozzle and pull back on the levers to lock the
Transfer Hose Connector in place.
