Installation and Operating Instructions
High Pressure Cleaner, Hot Water, Stationary
HSC1140-INOX Gas
First set the thermostat (6, fig. 6 - 3) inside the cabinet to the „Off“
position to set the water temperature.
WARNING
Before activating, hold the trigger gun and the spray lance tightly.
After activation of the trigger gun the emerging water jet exerts a jerky
recoil force (see also Fig. 6 - 5).
This may result in unintentional jerking away from the selected cleaning
object or the trigger gun slipping out of the hand, endangering the life
and limb of persons.
Unlock and pull the trigger lever (3, Fig. 6-2) of the trigger gun.
Set the main switch Start - Stop to position I on the cabinet door front.
The high pressure cleaner starts. The pump first delivers air from the
high pressure nozzle. After a short time, water then escapes.
WARNING
Risk of scalding due to hot water.
The hot water escaping from the high pressure jet must not come into
contact with persons. Otherwise scalding to persons may occur.
Set the Thermostat (6, fig. 6 - 3) inside the cabinet to the desired
temperature.
Set the main switch Hot Water to position I on the front of the cabinet
door.
Set the unloader valve (2, Fig. 6 - 3) inside the cabinet to the desired
operating pressure. The operating pressure can be read off the pressure
gauge (3, Fig. 6 - 3) while the trigger gun is activated. By turning the
unloader valve (see Figs. 6 - 4), the water quantity on the high pressure
pump can be reduced continuously to the lowest value. The quantity
regulation causes a lower operating pressure at the spray nozzle and a
rise in temperature up to 98° C according to the unloader valve setting.
If the trigger lever on the trigger gun is released, the high pressure
cleaner switches to pressureless circulation operation. After 5-160 sec.
(adjustable) circulation mode switches the system to stand-by mode.
When the lever on the trigger gun is pulled again, the motor and the
pump restart automatically.
General Information
If the system remains in stand-by mode for 20 minutes, the electronic
control switches the high pressure cleaner off as programmed.
To resume operation, move the Start-Stop main switch to position 0 and
then back to operating position I.
