2 | How to flush the system
For the duration of storage and transport, the membrane is protected
by means of a preserving agent. This preserving agent must be
flushed off before starting up the system for the first time. To do so,
the concentrate hose (refer to fig. E-1, item 1) and the permeate hose
(refer to fig. E-1, item 2) have to be routed to the drain.
2.1 How to flush off the preserving agent
Note:
For more detailed information on the handling of the control
unit, refer to Chapter F.
Switch on the mains switch and switch the operating mode selector
switch to the "OFF" position.
Open both solenoid valves ("DEAERATE") via Code 113, parameter
EnL: 1 and flush off the preserving agent from the system for a dura-
tion of 30 min. To do so, open parameter with P button, set ENL: 1
with ▲ button and confirm with P button.
Complete program step “DEARATE”: Open parameter with P button,
set EnL:0 with ▼ button and confirm with P button.
Exit the “EnL” program by simultaneously pressing the buttons ▼and
▲.
2.2 Filling mode
In filling mode (refer to fig. E-2), e.g. heating / cooling water
systems, direct the hose supplied with the system from the
permeate connection of the reverse osmosis system to the filling
valve or to the GENO-therm filling device.
The pressure switch is set to a switch-off pressure of 2.5 bar
= system pressure. If a higher or lower system pressure is required,
this can be set via the pressure switch (refer to fig. C-2, item 13).
Then switch on the reverse osmosis system via the selector switch at
the controller housing. The system produces permeate. Close the fill-
ing valve and monitor at which pressure the system switches off. Use
the adjusting screws to set to the desired switch-off pressure/system
pressure.
Note:
Based on the permeate output of the reverse osmosis, a max.
pressure of 3.5 bar can be reached. With an increasing counter-pres-
sure, the continuous permeate output will decrease.
