51  it  means  that  the  permeate  ca-
pacity  us  6  %  below  the  normal
160 l/h, i.e. 151 l/h. At the same
time  make  sure  that  the  pressure
on  the  manometer    (E-Figure  3)
does  not  exceed  15  bar  incl.  the
raw water pressure from the water
supply.
The  normal  pressure  indicated  on
the  manometer  in  order  to  obtain
normal  permeate  capacity  will  be
approx. 13.5-14.5 bar.
When  the  requested  pressure  and
permeate capacities have been ob-
tained,  check  again  if  the  outlet
amount has been adjusted correct-
ly.
When  both  valves  have  been  ad-
justed, they shall be locked with the
lock  nuts.  Please  take  care  not  to
move  the  valve  when  you  tighten
the lock nut.
NB!      When  the  valves  have  been
locked,  the  plant  shall  be  started
and  stopped  4-5  times,  and  then
the  flow  shall  be  checked  again;
the valves are re-adjusted if neces-
sary.
Now  check  that  the  quality  of  the
treated  water  on  the  permeate
hose  (A-Figure  3);  the  conductivity
shall be below 20 µS/cm (conduc-
tivity meter is available as accesso-
ry). If the water quality is below 20
µS/cm  it  is  OK  and  the  hose  can
be  led  back  to  the  hole  in  the  res-
ervoir tank.
The 50 litre reservoir tank now will
be filled up with treated water <20
µS/cm.
Write the operating data in the en-
closed  operating  journal  (see  sec-
tion – 13.5 Operating journal).

Start of transport
pump

The transport pump (G-Figure 3) is
controlled by a pressure switch and
hydrophore  is  preset  to  2.7  bar
from  our  factory,  so  they  do  not
have to be adjusted.
Note!  The  transport  pump  (G-
Figure 3) will not start until the res-
ervoir  tank  has  been  completely

full.  Wait  for  the  reservoir  tank  to
fill  up  completely  (approx.  20
minutes). Check that the level
switch  (H-Figure  3)  automatically
stops  the  plant  when  the  reservoir
tank is full.
NB: Do not touch the level switch.
Create  a  large  consumption  of
treated  water  to  get  the  air  out  of
the pump.
Check  that  the  transport  pump  (G-
Figure  3)  starts  up  automatically.
Check  that  the  pump  supplies  wa-
ter and pressure.
When  you  have  checked  the
transport  pump  and  found  it  to  be
in  order,  close  for  consumption  of
treated water.
Wait for the transport pump to stop
automatically.
Note! The transport pump does not
stop  until  20/30  seconds  after  the
consumption has ceased due to the
built-in delay in the control box.
Once  again  create  a  consumption
of  treated  water  and  this  time  let
the  transport  pump  (G-Figure  3)
empty approx. 25  litres of the res-
ervoir  tank  content.  Check  if  the
plant  starts  up  automatically  and
produces  treated  water.  This  can
be read on the flow meter (F-Figure
3).
The  plant  is  now  commissioned
and ready for use.

7.4

Use of by-pass

Furthermore the plant is furnished
with a manual by-pass for raw wa-
ter, i.e. if the plant for some reason
experiences

disturbances,

this

valve  can  be  opened  and  you  will
have  raw  water  on  the  outlet  for
consumption.  IMPORTANT!  When
the plant is restarted, you  must re-
member to  close the  by-pass  valve
again,  otherwise  you  will  get  a
mixture  of  permeate  and  raw  wa-
ter on the outlet.
