OPERATING INSTRUCTIONS
C
1. Refer to “Detergent Cleaning Precautions” pg. 6 before working with
detergents. Be certain to wear protective safety attire as stated on pg.
10.
2. Prepare detergent solution according to label directions. Never pump
acids, alkaline, abrasive uids or solvents through the unit.
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 not equipped with an adjustment knob, the detergent
ratio is preset and cannot be adjusted.
b. 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.
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 nozzle assembly is in the
low pressure detergent mode.
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 briey. 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.
7. 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 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.
QUICK CONNECT DETERGENT
SHUTDOWN:
1. Turn engine “OFF” as directed in the Engine Manual.
2. Turn the water supply “OFF”.
3. Pointing the gun in a safe direction, trigger gun momentarily to relieve
any trapped pressure.
4. Once pressure is relieved, disconnect the nozzle assembly.
5. Disconnect and drain gun, wand and hoses.
6. Wipe unit clean and store with gun, wand and hoses in a safe, non-
freezing area.
