4.4 Double spray lance, regulation of pressure and water volume - KSA-1
Turn spray lance pressure reducing valve

Clockwise (B): high pressure
Counter clockwise (A): low pressure/

detergent application
The spray lance employs a high pressure nozzle and a low pressure nozzle.
On KSA-1 pump systems the water volume is adjusted on the water regulation valve of the pump (2).
On KSA-1 pump systems the water volume is adjusted on the water regulation valve of the pump (2).
High pressure mode
The max. working pressure of the machine is reached when the pressure reducing valve (1) is completely
closed (B), and the water regulation valve (2) is fully counter-clockwise. In this position only the high pres-
sure nozzle is used - high pressure mode. The water volume is infinitely variable (2) between min. and
max. output. Reduced water volume = reduced pressure. With the trigger released, turn the water regu-
lation valve (2) to adjust volume and pressure (clockwise = Lower volume and pressure). Minimum volume
results in a working pressure of 580 psi through the high pressure nozzle (only), and a water volume of
approx. 2.4 gpm. If you want more water volume, the valve (2) should be turned counter-clockwise until
the desired result is achieved. 1 turn provides change of approx. 725 psi.

Low pressure mode
When the reducing valve (1) is completely opened (A), the pressure will be fully reduced. The nozzle
pressure will be approx. 60 psi. In this position both spray nozzles are used - low pressure mode / possi-
bility of dosing detergents.

Regulation of pressure/water volume
When using special COLORED spray lances, the pressure and the water volume may be chosen for the
individual cleaning task. The table shows the pressure (P) of the nine different nozzles, the water volume
(Q), the color code (C) and the number of pumps (N) required to support operation of the individual lan-
ces. Contact your ALTO distributor for further information.
