Karcher SB Wash Oel 50-10 F VA - Manual (Page 26)

- 12
Water and air escapes through the
drainage connection until the plant is
completely deaerated.
 Note:
Restrict backwashing to the absolute
minimum because otherwise the sen-
sor measuring cell can get exhausted
and this may necessitate a complete re-
generation of the concerned exchange
tank.
 Pull out the suction sieve fitted at the
brine hose from the guide pipes in the
salt tank.
 Press the valve flap (NR1) (directly be-
hind the programming system) using a
screw-driver.
The air closure valve gets filled and air
escapes through the suction sieve.
When air no longer escapes from the
suction sieve, release the valve flap.
 Insert the suction sieve back into the
guide pipes.
 Press the programme button and select
the function "DRAW / SLOW RINSE“
(Regeneriation)" by turning the button
in the direction of the arrow.
Water level in the salt tank falls contin-
uously.
Note:
The suction system needs to be deaer-
ated if there is air formation in the air
closure valve before the salt tank is
empty (residual level in the salt tank,
when empty, is approx. 7 cm) and the
ball floating in the air closure glass falls
down.
 Press the programme button and select
the function "REFILL" by turning the
button in the direction of the arrow.
The control valve automatically moves
to the function "TREATED WATER“
(operations). The salt tank is filled with
water.
 When the water level is correct, fill the
salt tank with salt tablets according to
DIN 19604 (also see chapter on Acces-
sories).
The plant is ready for operations when
these jobs are completed. Conclude the
start-up activities by doing a soft water test.
1 Flow meter for concentrate
2 Valve for concentrate
3 Valve for operating pressure
During first start-up:

Fill the membrane with initial tap water
pressure (net it).
 Open the concentrate valve fully.
 Set low operating pressure at the oper-
ating pressure valve.
 Rinse the memrane for 10 ... 20 min-
utes (foam formation during this proce-
dure is normal).
During fresh start-up after shutdown:

Let the rinsing run until there are no
bubbles to be seen at the throughflow
meter of the permeate.
 Open the operating pressure valve ful-
ly.
 Open the concentrate valve 2 by two
turns.
The permeate quantity depends on the op-
erating pressure and water temperature.
Note
Set the pressure for permeate production.

Set operating pressure at operating
pressure valve to 1.0 MPa.
 Pull out the red hose from the buffer
tank for permeate.
 Determine the permeate quantity per
unit of time using the measuring beaker
and stop clock or collection basin and
weighing scale.
 Adjust the operating pressure at the op-
erating pressure valve until the perme-
ate quantity given below has been
reached depending on the water tem-
perature.
ṇ
Warning
Risk of damage for pump and RO mem-
brane. Do not set operating pressure at a
level more than 1.4 MPa.
Tolerance ±15%
 Set concentrate quantity at the concen-
trate valve to the standard permeate
output. The yield is then approx. 50%.
 Set the clock for time-controlled regen-
eration of the base excahnger cylinder
in the SS wash.
 Check the plant for leaks; tighten
screws if required.
 Train the staff of the operator.
Note
Convince yourself that the operating staff
has understood all the instructions clearly.
