. Refer to "Detergent Cleaning Precautions"before working with detergents.
Be certain to wear protective safety attire.
. Prepare detergent solution according to label directions. Never pump
acids, alkaline, abrasive fluids or solvents through the unit.
. 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.
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
the detergent spray nozzle (#6540° BLACK) into the end of the wand.
NOTE: This injection system is designed to apply detergents under low
pressure only. It will not allow detergent solutions to be introduced
into the system unless the detergent nozzle (6540 Black) is
installed.
6. To apply solution; unlock the trigger gun and squeeze the trigger. In a
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
avoid streaking. Allow to soak briefly. DO NOT allow detergent solution
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
damaging painted surfaces.) Be certain to rinse a small section at a
time.
. To rinse; lock the trigger gun in the "OFF" position, securely quick-connect
the desired high pressure nozzle into the end of the wand. Unlock the
trigger gun and spray. It will take about 0 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.
