2.18.1 Basic warnings
Note
The AquaA may only be operated under the specified operating
conditions:
– Appropriate water pretreatment in accordance with the specified
inlet requirements is required.
– The control unit must be protected against humidity (splash water,
condensation water, etc.) and moisture.
– In the event of a defect of the control unit, the type of problem (effect
of the malfunction) should be recorded before dismantling the
system. A system that has been dismantled can only be repaired if
a detailed description of the problem is available.
– The total output (rated output) of the reverse osmosis system must
not be exceeded.
– Appropriate pipe fittings must be provided to ensure that the soft
water inlet side is reliably protected against a water inlet pressure of
6 bar.
– Only the membranes installed by the manufacturer may be used.
Replacement of membrane units with units not explicitly approved
for use by the manufacturer is not permitted.
Warning
Operator restrictions
Access to the AquaA reverse osmosis system must be restricted to
authorized personnel.
Warning
Preventing leakage damage
The following measures must be implemented to avoid severe damage
to buildings:

The room where the reverse osmosis system is operated must be
equipped with a floor drain and have a floor which is resistant to
water as well as the cleaning agents and disinfectants used.

To prevent damage to buildings outside dialysis hours (unattended
times without staff) caused by water leakage, a leakage monitoring
system with a shut-off function, such as the
AquaDETECTOR with
leakage sensors, should be installed in every room with user points.

If no leakage monitoring system is installed, it is recommended that
all supply tubes be disconnected from the ring main outside dialysis
hours (unattended times without staff).
