WARNING
To avoid rupturing a component, which can cause seri-
ous injury, including amputation; read warnings, page
4, and follow the instructions below.
Never install a shutoff device between the
heater and gun as this will trap the heated fluid
and not allow for expansion. If a fluid regulator
is installed between the heater and gun, never
use it as a shutoff device.
