sider that the cover of the plant
must be de-mountable for easy
servicing of the plant. Ensure that
the plant can easily be pulled out
for servicing.
You should also make room on
the back of the plant for the wa-
ter installation; especially you
should take into account the out-
let hose from the plant. The hose
may never be bent!
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 41 plant, must be drink-
ing water quality with maximum
500 mg/l TDS.
Max. raw water temperature is
25 °C. The plant is adjusted 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
* KMnO
:
10 mg/l

If there are doubts about the raw
water composition, a water ana-
lysis 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 50 µS/cm at 10 °C.

WATER
CONNECTIONS
Note: All water connections of
the plant must be made in com-
pliance with local regulations.
5.1
Connection of raw-water
(inlet water)
BWT keeps a complete assembly
kit for the BWT PERMAQ
pact 41 in stock.
At the inlet side of the plant a
ball valve must be installed to
provide for the disconnection of
raw water upon servicing the
plant.
Connect the ¾" flexible pressure
hose supplied with the plant to
inlet raw water at the back of the
plant. Connect the other end of
the hose to the raw-water supply.
The best operating result will be
obtained by connecting to mini-
®
mum ¾" raw-water pipes, as
using a smaller pipe dimension
might increase the risk of inade-
quate operating pressure and
consequent
drop-outs
plant, e.g. during flushing of
membranes by start-up.
5.2
Connection of permeate
(treated water)
Connect a minimum ¾" flexible
pressure hose to outlet permeate
at the back of the plant. The other
end of the hose must be connect-
ed to the consumer or a subse-
quent pipe connection for further
transport to the consumer of the
treated water.
Note: totally desalinated water
might
accelerate
Therefore always use corrosion
proof piping for the treated wa-
ter, 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).
Install the supplied 10 mm plastic
hose to outlet. It is important that
the hose is pressed all the way in.
The opposite end shall be con-
nected to outlet. The hose may
not be led down into the outlet
water, though, since the water
®
Com-
may risk getting sucked back into
the plant during standstill. Note!
The outlet hose may never be
bent or in any other way ob-
structed, as this would damage
the plant membrane.

ELECTRICAL
CONNECTIONS
Note! The electrical connections
must be made in compliance with
local regulations.
The electrical connection to the
BWT PERMAQ
plant must be as follows:
*Voltage:
*Fuse:
*Max. power consumption:
of
the
Colour code of power cable:
Blue wire:
Brown wire:
Yellow/green wire: PE
All internal connections in the
plant like e.g. pump control and
level control are pre-assembled in
our factory. This means that only
the supplied power cable which
is connected to the control box
must be connected to a power
plug or hard wired.
If for some reason you need to
change
corrosion.
power cable, please cf. Annex –
13.3 Wiring Diagrams.

COMMISSIONING OF
PLANT
Check prior to commissioning
that all water and electrical con-
nections have been made as
described in the previous sections
and are in compliance with local
regulations.
