Emergency Stop; Pump Shutdown; System Shutdown; Flushing And Storage - Graco Saniforce Operation

Emergency Stop

Manual control systems do not have this feature.
The STU electro-pneumatic control box has an
emergency stop button below the display screen.
Pressing the emergency stop button will stop
the pump but does not depressurize the system.
Resetting the emergency stop places the system in
a ready state. The system must be restarted by the
operator. Restarting the pump will start in slow mode
for a period of time and then switch to fast mode.
To reset the emergency stop button, rotate the knob
in a clockwise direction until a click is heard or felt.
Do not use the emergency stop button to stop the
system during normal operation.

Pump Shutdown

At the end of the work shift and before you check,
adjust, clean, or repair the system, follow the

Flushing and Storage

• Flush before fluid can dry in the equipment, at the
end of the day, before storing, and before repairing
equipment.
• Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
• Always flush the pump and relieve the pressure
before storing it for any length of time.
NOTICE
Flush the pump often enough to prevent the
fluid you are pumping from drying or freezing in
the pump and damaging it. Store the pump at
32°F (0°C) or higher. Exposure to extreme low
temperatures may result in damage to plastic parts.
