POSITIONING OF THE
PLANT

The  plant  must  be  placed  in  a
non-freezing  environment  on  a
even foundation so that the water
in the reservoir does not overflow
when the tank is full.
the  foundation  must  be  able  to
stand  a  load  of  approx.    330  kg
which  is  the  plant  weight  when
full.
The plant is furnished with casters,
so if you wish to be able to move
the  plant,  you  should  keep  the
foundation even and solid.
The outside measures of the plant
are  (WxDxH):  580x630x1350
mm,  but  when  positioning  the
plant you should take into account
that the cover shall be demounted
during  maintenance  work.  Either
you  must  calculate  with  an  addi-
tional  370  mm  in  height  to  be
able  to  lift  the  cover,  or  it  should
be possible to roll the plant out for
servicing  (e.g.  place  it  under  a
table or equal).
You  should  also  make  room  on
the back of the plant for the water
installation;  especially  you  should
take  into  account  the  outlet  hose
from the plant.
The hose may never be bent!
Positioning  of  the  plant  must  be
done  in  a  way  so  that  the  air
intake  on  the  front  never  gets
covered.
There  must  also  be  room  in  front
of  the  plant,  so  that  it  is  possible
to  freely  read  the  flow,  and  the
suction of the high-pressure pump
can  take  place  without  obstruc-
tion. Also it should be possible to
pull  out  the  plant  in  connection
with maintenance.
In  case  of  a  stoppage,  the  reser-
voir  may  overflow.  Therefore
there should always be a drain in
the immediate vicinity of the plant
so  that  the  overflowing  water
does not cause damage.

If there is no floor drain near the
plant, installing the plant is at
your own risk.

WATER QUALITY

The raw water, which is to be
treated in the BWT PERMAQ

Compact  plant, must be softened
drinking  water  quality  with  maxi-
mum  500  mg/l  TDS.  Max.  tem-
perature:  25  °C.  The  plant  is  ad-
justed at 10 °C in our factory.
The  raw  water  may  maximum
contain:
* Fe:

0.05 mg/l

* Mn:

0.02 mg/l

* Cl:

0.1 mg/l

* Turbidity: 1.0 NTU
* SDI:

3.0 %/min

* KMnO4 max:   10 mg/l
If  there  are  doubts  about  the  raw
water  composition,  a  water  anal-
ysis must be made. The plant must
be  connected  to  a  raw-water
pressure  of  minimum  2  bar  and
maximum  7  bar.  The  quality  of
the treated water will be less than
20 µS/cm at 10 °C.

WATER CONNECTIONS

Note! All water connections must
be in compliance with local regu-
lations.

5.1

Connection of inlet water
(raw water)

On  the  inlet  side  you  must  fit  a
ball  valve  so  that  the  water  may
be  cut  off  during  maintenance  of
the plant.
Install a ½” flexible pressure hose
on  the  pre-filter  of  the  plant  (A-
Figure  2).  The  opposite  end  shall
be  connected  to  the  raw-water
supply.
The  best  operating  result  is  ob-
tained  by  connecting  to  minimum
¾”  raw-water  pipe.  That  reduces
the  drop  in  pressure  to  the  plant.
With  a  too  small  raw-water  con-
nection,  there  will  be  a  risk  of
outage on the plant due to lacking

water pressure, e.g. when rinsing
out the membranes at start-up of
the plant. Note! Fit the built-in
flowmeter to the cabinet.

5.2

Connection of permeate
(treated water)

Fit  the  ¾”  flexible  pressure  hose
to  the  transport  pump  (B-Figure
2).  The  opposite  end  shall  be
connected  to  the  consumer  of  the
permeate  or  pipe  connection
which  is  led  to  ½”  consumer  of
the permeate.
Note!  Totally  desalinated  water
may  speed  up  corrosion.  There-
fore,  always  use  non-corrosive
piping  for  the  treated  water,  e.g.
stainless steel or PVC.

5.3

Connection of outlet hose

Start  by  dismounting  the  “bent”
blue  hose  which  is  fitted  on  the
outlet valve (B-Figure 3).
Install the supplied 10  mm plastic
hose to outlet valve (B-Figure 3). It
is  important  that  the  hose  is
pressed  all  the  way  down.  The
opposite  end  shall  be  connected
to outlet. The hose may not be led
down  into  the  outlet  water,
though,  since  the  water  may  risk
getting sucked back into the plant
during  standstill.  Note!  The  outlet
hose may never be bent or in any
other  way  obstructed,  as  this
would  damage  the  plant  mem-
brane(s).

5.4

Connection of overflow
hose

On  the  back  of  the  plant,  on  the
overflow nozzle (C-Figure 2), you
shall connect a ½” plastic hose to
the  floor  drain  or  another  subja-
cent  drain.  This  overflow  is  a
safety  overflow  in  case  an  fault
occurs  on  the  level  switch  of  the
plant  and  the  reservoir  tank  as  a
consequence  gets  filled  to  over-
flowing.
