OPERATING INSTRUCTIONS
CLEANING WITH DETERGENTS:
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.
3. Connect the detergent hose (4) to the unit as shown on page 8.
4. Immerse the strainer into the detergent solution to allow detergent to
siphon.
5. Be certain the water supply is completely turned "ON".
6. With the trigger gun locked in the "OFF" position, push the nozzle cover
at the end of the wand away from the trigger gun for low pressure.
7. 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.
8. To rinse: lock the trigger gun in the "OFF" position, pull the nozzle cover
at the end of the wand toward the gun. 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.
9. 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. 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. Drain gun, wand and hoses. Once drained, disconnect hoses.
7. Wipe unit clean and store with gun, wand and hoses in a safe area.
