16.2 Emergency mode with soft water
Soft water can be fed into the loop if all the pumps and the control system fail.
1. Switch the system off at the main switch
2. Place the sterile filter insert in the pre-filter (note intake water pressure)
3. Open valves
K1/K3
(
K1
lever setting: horizontal = closed, vertical = opened) by pulling the flap lever
to the outside and moving 90° upwards.
4. Switch on the hard water monitor by hand (if available)
During soft water emergency operation, LMW recommends closing the flap on the loop return to avoid
premature depletion of the softener.

WARNING
The emergency operation of a dialysis machine with soft water is only permitted in agree-
ment with and written approval by the physician carrying out the treatment!
NOTICE
LMW advises carrying out a comprehensive analysis of the soft water quality with regard to
chemical and microbiological limit values if soft water is used for emergency operation.
WARNING
Disinfection of the dialysis machine in soft water emergency operation is only permitted
after complete separation (pipeline separation) between the dialysis machine and the soft
water supply.
WARNING
During soft water operation, no active control of conductivity takes place through the RO.
For this reason, water hardness must be checked regularly according to legal regulations.
IMPORTANT If the water intake pressure is greater than the loop pressure set at UV1, the water passes
through to the supply tank through this overflow valve:
•
Danger of supply tank overflowing, even without dialysis machines and consumers
connected!
•
The softener will become depleted prematurely.
In this case, LMW recommends installing a shutoff valve at the end of the loop and clos-
ing this during soft water emergency operation. Consumption them corresponds to water
requirements for dialysis.
