OPERATING INSTRUCTIONS
Cleaning with detergents
Refer to “Detergent Cleaning Precautions” pg. 4 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.
Some units are equipped with adjustable detergent knobs. Locate the clear vinyl hose which leads to the pump head.
•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.
•If your injector is not equipped with an adjustment knob, the detergent ratio is preset and cannot be adjusted.
1.Immerse the detergent strainer into the detergent solution to allow detergent to siphon.
2.With the trigger gun locked in the “OFF” position, secure
Note: This injection system is designed to apply deter- gents under low pressure only. It will not allow deter- gent solutions to be introduced into the system unless the nozzle assembly is in the low pressure detergent mode.
3.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.
4.To rinse; lock the trigger gun in the “OFF” position, securely
5.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.
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,
