Fluid Connections and
Accessories
To handle fluid expansion caused by heat:
• Use flexible hoses between heater and gun.
• Install a properly sized accumulator down-
stream from the heater.
• Install a pressure relief valve (X) pre-set to
relieve pressure when it exceeds the system
maximum working pressure.
To prevent serious injury caused by component or
equipment rupture:
• Never install a shutoff device between the heater
and gun as this will trap the heated fluid and not
allow for expansion.
• Never use a fluid regulator as a shutoff device if it
is installed between the heater and gun
• Provide a means for adequately handling fluid
expansion caused by heat.
