A note about operating temperatures
The MaxCharge nozzle should always be operated at temperatures above 10° Celsius (50° Fahrenheit).
when the ambient temperature is colder than this, the evaporative cooling caused as the spray is
atomized will freeze the nozzle opening.
nozzle freeze-up can also occur when the liquid to be sprayed is colder than 10° C (50° F).
