Flushing and Storage

WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
Flush the pump when necessary to prevent the fluid
you are pumping from drying or freezing in the pump
and damaging it. Use a compatible solvent.
Before storing the pump, always flush the pump and
relieve the pressure.
Operation
Recirculation Line
The recirculation tube (K, supplied with Models
236–870, 224–833, and 236–412) drains unused fluid
back into the fluid container, ensuring an even flow at
the gun. Recirculation also provides gentle fluid agita-
tion. To recirculate fluid, open the drain valve (J) while
you are spraying. To stop recirculation, close the valve.
Surge Tank (Models 236–628, 236–869,
236–412, 236–868, and 236–414)
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
The surge tank filter screen may require periodic
cleaning. First, relieve the pressure. Unscrew the
surge tank cover from its base and remove the filter
screen. Clean the screen with a compatible solvent
and reinstall it in the surge tank.
An optional Viton gasket is supplied for the surge
tank, for use in applications where the standard EPDM
gasket is unsuitable.
