CLEANING WITH DETERGENTS

1. Refer to "Detergent Cleaning Precautions"before working with detergents.

Be certain to wear protective safety attire.

2. Prepare detergent solution according to label directions. Never pump

acids, alkaline, abrasive uids or solvents through the unit.

3. 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 briey. 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.

SHUT-DOWN

1. Move the On/Off switch to the "OFF" position to turn unit off.

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 the unit from the power source.

6. Disconnect and drain gun, wand and hoses.

7. Wipe unit clean and store with gun, wand and hoses in a safe area.
