Installing the plant

Only for authorised techni-
cians!
!
Initial startup
Check the direction of rotation of the ad-
vance pump. The direction of rotation
must be in agreement with the arrow on
the casing.
Check that water inlet has the required
flow and the permissible temperature.
Check oil level of the pump.
Before using for the first time, cut off the
tip of the lid of the oil tank on the water
pump.
Settings
Operational readiness period
Initiate the stand by-period with the po-
tentiomenter on the electronic control.
The time can be set between 2 and 8 min-
utes. A simple scale of standard values is
printed on the control board.
Installation water softener (optional)
Use hard water for hot water operation to
protect against calcification In addition add
water softener to the water. The dispensing
flow can be adjusted to the degree of water
hardness.

Danger
Risk of electrical voltage! Setting may only
be done by an electrician.
Determining the hardness of tap water:
– through the public water supply works,
– using a hardness tester (order no.
6.768-004)
Start the rotation potentiometer on the
water softener board.
You can refer to the correct setting in the ta-
ble.

Pause (in 50 40
seconds)
Example:
For a water hardness of 15 °dH, set 6 on the
value scale of the speed potentiometer.
This results in a pause of 31 seconds, i.e.
the solenoid valve will open briefly every 31
seconds.
Installation
Note
The water connection, the high pressure
network as well as the electrical connection
can only be carried out by authorised ex-
perts in accordance with local regulations.
– The installion should be set-up in a dry,
non-explosive environment.
– The installion should be installed on firm
and even ground.
– The installion should be easily accessi-
ble for maintenance work.
– Room temperature should not exceed
40 °C.
The following are required for installation:
– Wall mount
– Installation with the mounting kit floor
rack (optional)
When wall mounting, please check the
load-bearing capacity of the wall. The
mounting material provided is for walls
made of concrete or solid brick with a wall
thickness of 11.5 cm (for drilling figure
please see dimension chart).

Electrical connection

– For connection values, see technical
data and type plate.
– The power supply designed for operat-
ing the plant must be suitable for contin-
uous operations.
– The electrical connections must be
done by an electrician according to IEC
60364-1.
– Current-carrying parts, cables and ap-
pliances in the working area must be in-
stalled in a defectless state and must be
protected against water sprays.
A Connection terminals
Establish the electrical connection.

– Design the water supply for continuous
6 5 4,5
operations.
– The water feed line is provided with a
stop valve and can be moved over a
pressure hose and attached to the high
pressure system.

– If the cross section of the line is too
small or if the advance pressure is too
low, there will be a lack of water.
– When the advance pressure or the rinse
pressure is too high, it is absolutely nec-
esary to install a pressure reducer.
– A water drain must be present at instal-
lation site.
