Caution
: If the burner does not go off, hold the trigger on the gun
open, and shut the gas supply to the machine. Continue to hold the trigger until
the burner extinguishes, and then turn the Pump switch off. This will prevent
damage to the machine. Do not attempt to restart the machine, and contact
PEM.

Adjusting chemical concentration
To apply acidic cleaners, a downstream injector is used, which is specifically
designed for the system. The injector itself is precision calibrated and non-
adjustable. However, the ratio of chemical-to-water is easily adjusted using the
color-coded metering orifices that can be threaded into the chemical pick-up.
An assortment of various sized metering orifices is included with the machine in
the instruction packet. See Table 3. The injector will draw approximately 2.5%
chemical with no metering tips. The metering tips can be used to reduce this
percentage in 0.2% increments down to approximately 0.8 percent. These
metering tips thread into the chemical barb on the injector. Install them as
follows:
Note:
If your machine is equipped with an optional siphon valve, the valve
adapter must be removed to change the metering tips.
1.
Slip the vinyl pick-up tube off the barb
2.
Thread the selected metering tip into the injector barb.
3.
Replace the vinyl tube.
