7.15 Switching OFF the Microdispensing System
– Step 1: The current dispensing cycle must be completed, so that the valve is in home position.
– Step 2: Lower the supply pressure to atmospheric pressure (because in initial position, the
valve is still opened). Disengage the pneumatic supply. If required, close the cartridge by
using locking pin MDT 309.
– Step 3: Switch OFF the control unit (ON/OFF button at the rear end). After switching OFF the
control unit, please wait a few seconds.
– Step 4: Disconnect the valve from fluid supply.
– Step 5: Remove all cables from the valve.
– Step 6: Unscrew the screws used for fixing the valve in place.
After working with self-curing substances, immediate cleaning is advisable in order to avoid
clogging. This concerns the valve itself and all parts in contact with the fluid. The valve and its
subcomponents have to be dismantled and cleaned (see chapter 9, page 120).
