Water System; Detergent / Caring System; Lance And Spay Gun - Kranzle quadro 9/170 TST Operating Manual

Water supply system
The water must be lead to the high pressure cleaner under pressure (2 – 8 bar
ad-mission pressure). A float valve regulates the water inlet. Then, the water is
sucked by the high pressure pump from the water tank and supplied to the lance
under the set pressure. The high pressure jet is formed by the nozzle at the end of
the lance.
Detergent and caring system
The high pressure pump can also suck a detergent/caring
agent and mix it with the high pressure jet. The additive
is sucked through the pump and brought in with the set
pressure.
Insert the detergent hose into the detergent container and
open the detergent valve (6). The detergent must have
the ph-value 7-9 neutral.
The detergent discharges with the water at the high pres-
sure nozzle.
Only open the dosing valve, if the chemistry sieve is placed in
a liquid. Sucked air leads to destruction of the pump seals !!!
The rules concerning the environment, refuse and
ground water protection must be complied with!
Lance with spray gun
The machine can only be operated when the safety trigger is squeezed.
When the lever is squeezed, the spray gun opens. The liquid is then pumped
to the nozzle. The spray pressure increases and quickly reaches the selected
operating pressure. For the deairing of the system open and close the gun quickly
a few times. When the trigger is released, the trigger gun closes and any further
spraying of liquid from the lance is stopped and the pressure gauge must show 0
bar.
The increase in pressure when the trigger gun is closed causes the unloader
valve-safety valve to open. The pump remains switched on and continues to pump
liquid through the pump at reduced pressure. When the spray gun is opened, the
unloader valve - safety valve closes and the pump ressumes spraying from the
lance with the selected operating pressure.
The spray gun is a safety device. Repairs should only
be performed by qualified persons. Should replacement
parts be required, use only components authorized by
the manufacturer.
