Tridak® Model 1200 Filling System User Guide
Operating the System
Entering Mode of Operation
The unit has two modes of operation, Pump Mode and Flow Mode. Pressing one of these buttons (Figure 5)
while the unit is idle will enter the system into the respective mode.
Pump Mode
allows the valves to operate continuously throughout the entire filling sequence and is
recommended for higher viscosity materials to aid in filling.
Flow Mode
allows the valves to operate only a few times during the filling process and is recommended for
lower viscosity materials.
Note: Some experimentation will need to be done to determine the best mode of operation for the material you
are using.
Filling a Syringe
Once the system is set up, purged, the fill height has been adjusted, and the mode has been selected, it is
ready to fill a syringe. Place an empty syringe with a plunger inserted onto the Nozzle Block. Simply press the
Footswitch or the Cycle Start Button (Figure 5). The unit will run until the Height Adjustment reaches the end
of its stroke and the stop. When the unit has stopped, the syringe can be removed and replaced.
Speed Control Adjustments
The Model 1200 allows for complete and quick filling of syringes by controlling the fill rate of materials as well
as controlling the rise rate of the plunger. This design allows for an even fill on both sides, simultaneously. The
rise rate of the plunger is controlled by the Speed Control Knob located on the front panel (Figure 6).
Note: The fill rate must exceed the plunger rise rate or you will not completely fill the syringe.
Adjustments to the Dispensing Valve
Model 828 dispensing valves are preset before shipment. If adjustment is needed, please refer to the Model
828 Dispensing Valve User Guide. This manual is included in your shipment.
Reloading System Material
1.
Remove the Air Line from the Cartridge Retainer.
2.
Using a wrench, remove the Fill Tubing from the Cartridge End Fitting.
3.
Install a filled Cartridge Retainer.
Note: To minimize air pockets when reloading, push down on the cartridge piston until material is at the
cartridge fitting end and then install the cartridge retainer.
