Kärcher HDS 12/14-4 ST Instructions Manual page 36

Firmly installed electrical connection
 Establish the electrical connection.
A main switch that can be locked (figure 3 - item 6) is to be in-
stalled at a safe and easily accessible place to switch off the sta-
tionary high pressure cleaner.
The contact opening of the main switch must be minimum 3 mm.
Electrical connection with plug/ socket
 Install Cekon plug on the connection cable of the appliance.
 Insert Cekon plug into the socket.
To switch off the stationary high pressure cleaner, the Cekon plug
must be easily accessible so that it can be removed from the
mains.
Initial startup
 Before using for the first time, cut off the tip of the lid of the oil
tank on the water pump.
Measures to be taken before start-up
Danger
Risk of explosion! Only refill diesel oil or light fuel oil. Unsuitable
fuels, e.g. petrol, are not to be used.
 Refill fuel tank.
Caution
Hot water operations without fuel will cause damage to the fuel
pump. Ensure adequate fuel supply before starting hot water op-
erations.

 Remove spring (c) from the lid support (b) of the softener tank
(a).
 Fill the tank with Kaercher softener liquid RM 110 (Order no.
2.780-001).
Danger
Risk of electrical voltage! Setting may only be done by an electri-
cian.
 Determining the hardness of tap water:
through the public water supply works,
–
using a hardness tester (order no. 6.768-004)
–
 Remove the appliance cover.
 Open the switch box at the operating panel.
 Set the speed potentiometer (a) according to the water hard-
ness. You can refer to the correct setting in the table.
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.
