Operation after starting up
1.  Carefully connect the high-pressure hose to the quick-coupling of high-pressure cock (2). 

Any impurities should be removed prior to coupling.

2.  Fit the spray lance (6) in the quick-coupling of the spray pistol (5).
3.  Slowly turn the handle of the high-pressure cock (1) to open position and start your cleaning 

work.

Admixture of detergents
1.  Set the dosage valve on the foam injector to a concentration of 1-5%.
  When adjusting the dosage valve please note that maximum admixture of detergent is 5% 

when the dosage valve is fully opened.

  (Percentages apply to detergents and disinfectants in aqueous solutions. These values will 

be modified if other viscosity rates are used).

2.  Apply the desired detergent or disinfectant by means of the foam lance (7).
3.  Fit the DELTABOOSTER spray lance (6) (low pressure) in the quick-coupling (5) of the spray 

pistol and after-rinse.

4.  If the injector is only used at long intervals make sure to rinse it in clean water every time it 

has been used. This may be done by putting the suction hose of the injector in a container 
with clean water and letting the injector suck clean water for 1 to 2 minutes with a fully opened 
dosage valve.

After use
1.  Close the high-pressure cock by turning the handle (1) to closed position and relieving the 

hose of its pressure by activating the spray handle until the hose is void of pressure.
