3. POSITIONING OF
THE PLANT
The plant must be placed in a non-
freezing environment on an 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. 100 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): 350x560x750 mm,
but when positioning the plant you
should consider that the cover shall
be demounted during maintenance
work. Either you must calculate
with an additional 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 in-
stallation; especially you should
take into account the outlet hose
from the plant. The hose may nev-
er be bent!
Positioning of the plant must be
done in a way so that the air in-
take on the front never gets cov-
ered.
There must also be room in front of
the plant, so that it is possible to
freely read the flow, and the suc-
tion of the high-pressure pump can
take place without obstruction. Al-
so it should be possible to pull out
the plant in connection with
maintenance.
In case of a stoppage, the reservoir
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.
4. WATER QUALITY
The raw water, which is to be
treated in the BWT PERMAQ
®
Compact 51 plant, must be sof-
tened drinking 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 con-
tain:
* Fe:
0.05 mg/l
* Mn: 0.02 mg/l
* Cl: 0.1 mg/l
* Turbidity: 1.0 NTU
* SDI:
3.0 %/min
* KMnO4: 10 mg/l
If there are doubts about the raw
water composition, a water analy-
sis must be made. The plant must
be connected to a raw-water pres-
sure of minimum 2 bar and maxi-
mum 7 bar. The quality of the
treated water will be less than 20
µS/cm at 10 °C.
5. WATER CONNEC-
TIONS
Note! All water connections must
be in compliance with local regula-
tions.
5.1 Connection of raw
water (inlet water)
BWT sell complete assembly kits for
BWT PERMAQ
® Compact 51.
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 out-
age 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 per-
meate (treated wa-
ter)
Fit a ¾" flexible pressure hose to
the transport pump (B-Figure 2).
The opposite end shall be connect-
ed to the consumer of the treated
water or pipe connection which is
led to consumer of the treated wa-
ter. Note! Totally desalinated water
may speed up corrosion. There-
fore, always use non-corrosive pip-
ing for the treated water, e.g.
stainless steel or PVC.
5.3 Connection of out-
let hose
Start by dismounting the “bent”
blue hose which is fitted on the out-
let 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 op-
posite 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 membrane.
5.4 Connection of over-
flow 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 overflowing.
