3.

Some units are equipped with adjustable detergent knobs.  Locate the
clear vinyl hose which leads to the pump head.

a.

If your injector is equipped with an adjustment knob on the pump
head, you may adjust the amount of detergent desired by turning the
knob completely counterclockwise to set at the maximum siphon
rate.

b.

If your injector is not equipped with an adjustment knob, the
detergent ratio is preset and cannot be adjusted.

4.

Immerse the detergent strainer into the detergent solution to allow
detergent to siphon.

5.

With the trigger gun locked in the “OFF” position, securely quick-connect

6.

NOTE:  This injection system is designed to apply detergents under

low pressure only.  It will not allow detergent solutions to be intro-
duced into the  system unless the nozzle assembly is in the low 
pressure detergent mode.

few moments a detergent/water mixture will exit the low pressure nozzle.  
Start spraying the lower portion of the surface being cleaned and move
up, using long overlapping strokes.  Applying from the bottom up helps

to dry on the surface.  (Avoid working on hot surfaces or in direct sunlight 
to minimize the chances of the detergent drying, which may result in

connect the desired high pressure nozzle into the end of the wand.
Unlock the trigger gun and spray.  It will take about 30 seconds to purge
all detergent from the line.  For best rinsing results, start at the top and
work down.

8.

Siphon a gallon of water through the low pressure detergent injection
system after each use.  This prevents the possibility of  corrosion or
detergent residue causing mechanical problems during the next use.
