Adjustable Chemical Injector 2-8 GPM

Allows for water flow adjustment from the pressure pump. By adjusting the water flow through the injector, a restriction causes a vacuum which allows the detergent to be drawn through the hose barb when a large orifice nozzle is used. With the adjustment feature, the injector can be used with a variety of water flows, replacing injectors with fixed orifices that are sized to specific flows.

Injector ratios are approximate

They vary with the lift required, downstream restrictions, viscosity, temperature, etc

To determine the exact siphon ratio for your application: (1). Operate the injection feature for one minute

(2). Measure how much detergent was used

(3). Subtract the amount of injected detergent from the total amount of liquid discharged

(4). Divide this number from the amount of injected detergent. EXAMPLE: If the total amount of liquid discharged equals 5 gallons, and the detergent injected equals 58 oz.(0.45 gal.), the exact ratio woild be determined as follows: 5.0 -0.45=4.55 divided by 0.45=10. The ratio is 10 parts water to 1 part detergent.
(1). Connect the discharge port of the cleaner to the inlet port of the injector. (the arrow on the injector housing should point in the direction of the water flow)

(2). Connect dwonstream components, such as discharge hose and gun, to outlet port

(3). Connect the detergent hose to the hose barb and secure

(4). Place the other end of the hose into the detergent

(5). Turn on the water. On the ST-62 also turn adjustment to maximum counter clock-wise

(6). To activate injector, employ the large orifice nozzle. The ST-62 will now need to be adjusted clockwise for detergent suction.
