Initial Start-Up

1. Open the water inlet.
2. Vent the hot water circulation pump by loosening the

venting screw and then tightening it again.

Venting screw

3. Turn the main switch to "1".
4. Vent the circulation pump frost protection by loosen-

ing the venting screw and then tightening it again.

Putting the base exchanger into operation

(WAT-SE.../255B)

Backwash

1. Insert the overflow hoses of the base exchanger and

salt tank into the on-site waste water pipe.

2. Fill the salt tank with water (approx. 10 cm above the

upper edge of the sieve).

Do not add salt yet!

3. Slowly open the fresh water stop valve and wait until

the pressure tank has filled with water.

4. Remove the cover of the control valve.
5. Press the programme button and select the "Back-

wash" function by turning it in the direction of the ar-
row."

Programme button

Air and water escape through the waste water con-
nection until the system is completely vented.

Note

Limit backwashing to the absolute minimum, otherwise
the sensor measuring cell may be exhausted and a
complete regeneration of the respective exchange tank
will be necessary.

6. Pull the suction sieve attached to the brine hose out

of the guide tubes in the salt container.

7. Press the valve flap NR1 (directly behind the pro-

gramme unit) with a screwdriver.
The air shutter valve fills and air escapes through
the suction sieve.

8. If no more air escapes from the suction sieve, re-

lease the valve flap.

9. Reinsert the suction sieve into the guide tubes.

Regenerate

1. Press the programme button and select the "Salt-

ing+Washing" function by turning it in the direction of
the arrow."
The water level in the salt tank decreases continu-
ously.

Note

If air forms in the air shutter valve before the salt con-
tainer is empty (residual level with empty salt container
approx. 7cm) and the ball floating in the air shutter glass
falls down, the suction system must be vented.

Filling / washing clean

1. Press the programme button and select the

"Fill+Wash clean" function by turning it in the direc-
tion of the arrow.
The control valve automatically moves to the "Oper-
ation" function. The salt tank is filled with water.

Filling the salt tank

1. When the water level is correct, fill the salt tank with

tablet salt according to DIN 19604 (see also chapter
Accessories).
After completion of this work, the system is ready for
operation.

2. Complete the initial startup of the base exchanger

by carrying out a soft water check.

Putting the RO system into operation

Initial Start-Up

1. Fill the membrane with tap water pressure (wet).
2. Rinse the membrane for 10...20 minutes.

(Foam development during this process is normal).

Restarting

1. Continue the rinse until no more bubbles are visible

on the permeate flowmeter.

Check pressure of wheel cleaner (option)

1. Check the pressure of the detergent solution.

Target value: 0.9...1.0 MPa (9...10 bar).

2. If necessary, correct the pressure by turning the ad-

justment screw on the pump.

Adjustment screw

Check the system functionality

1. Check the burner setting.
2. Check all system functions.
3. Check all the washing programmes at all the wash-

ing stations.

4. Check the system for leaks and re-tighten screw

connections if necessary.

Putting the gas burner (option) into operation

The initial startup of gas burner may only be carried out
by authorised specialist personnel of the burner manu-
facturer.

●

The device must be connected to its own chimney.

●

The exhaust system must be carried out in accord-
ance with local regulations and in consultation with
the responsible master chimney sweep.

Gas device with exhaust gas system that takes the

combustion air from the installation room

Type B23

Gas device without flow protection, in which all parts of
the exhaust gas path that are under excess pressure
have combustion air flowing around them.
The B23 installation opens up the possibility of connect-
ing the device to a conventional single-exhaust-gas
chimney in accordance with DIN 18160 and operating it
as room air dependent. The prerequisite is that the
chimney is suitable for the connection of condensing
boilers (e.g. by refurbishing the chimney by inserting a
stainless steel pipe).
