CHEMICAL INJECTOR & JET KIT - 1.8 SSQ Adjustable - B19.2087SSQBL

USES:

• Wash and remove mold, dirt, and mildew from various structures without using ladders or scaffolding.
• Sterilization of housing areas for agricultural needs.
• Caustic spraying that requires using harsh chemicals that can destroy pumps.
• Degreasing heavy equipment using pressure soap without going through the pump.

Image with letter positions key:

• A. Is the inlet to the injector jet this is connected to the SSQ coupling on the end of your lance.
• B. This is the chemical dose control. (when you initially start make sure this is unwound until is stops)
• C. This is the outlet adjustable spray jet which adjusts the width of the spray by turning the body left or right.
• D. This is your chemical pipe.
• E. This is the filter which is submersed in the chemical.
• F. This is the prechamber before the hight pressure water passes though the injector.
• G. This is the injector body. 
• H. This is the chamber where the mixed solution is carried to the outlet spray jet.
• F ; G & H Can be unscrewed to clean the injector nozzle

How to calibrate

1. Check how much water your pressure washer pumps. For example: 12 litres of water per minute.
2. Please remember the maximum water that is allowed through at 200bar is 23 litres /per minute
3. We then need to establish how much chemical it will suck through the chemical tube per minute. We do this by putting the chemical pick up in a fixed quantity of water (say 500ml). We then see how long it takes to suck this quantity (some prefer to use a measuring jug to see how much water is sucked in a certain time).
4. So, for example, if the injector sucks the 500ml in 50 seconds [(500ml divided by 50sec) x 60sec] or 300ml in 30 seconds [300ml x 2 to give us the about in 60sec], we know that 600ml will be sucked in one minute, and our machine is pumping 12 litres of water per minute.
5. We then know that the ratio is 600ml to 12000ml which is 1:20 (12000ml divided by 600ml)
6. The chemical mixture is then diluted with water to achieve the ideal ratio, or the variable dosage control is set on the injector.
