Switching OFF the MDS
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 car-
tridge by using locking pin MDT 309.
Step 3:
Switch OFF the control unit
(ON/OFF button at the rear end).
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 con-
tact with the fluid. The valve and its subcomponents have to be dismantled
and cleaned, as described in the chapter 8 (“Cleaning”).
