Tridak® Model 2200 Cartridge Filling System User Guide
Removing the Tank Top after Being
Pressurized
1.
Remove the air line to the Tank using the Quick Connect (user supplied).
2.
Slowly open the Release Valve (Figure 1) by rotating its Wing Knob counter-clockwise. Keep it in the open
position until the air pressure is completely exhausted, then return it to its original (closed) position.
3.
Once you can no longer hear any air escaping, the Clamp Screws that secure the Top can be loosened.
4.
After all of the Clamp Screws are loosened, the Clamp Screws can be pivoted away from the Tank Top and
the Top can be removed.
CAUTION!
In the event that the main air (the air that goes to the machine's inlet panel) is
disconnected from the system for any reason, the tank will bleed down to atmospheric
pressure and the dispense valve will open. This will lead to material being dispensed onto the
surrounding area in an amount that is viscosity dependent. For this reason an adequately
sized waste receptacle must always be placed under the nozzle assembly whenever the
machine is left unattended. If it is desired to leave the machine without a receptacle or the
receptacle does not have an adequate size, then the stroke adjustment on the valve (see the
section titled Valve Adjustments) can be set so that the valve cannot open even with the loss
of air pressure. While this creates a fail-safe configuration the user must, of course, readjust
the valve prior to putting it back in operation.

Valve Adjustments
Adjusting the Valve Stroke
Note: The valve is supplied factory adjusted. The adjustment screw can be used to fine tune the flow rate to the
valve, provide a fail-safe means of shutting the valve off, or minimize the amount the valve opens in order to
minimize the amount of surge when the valve closes. In all cases, the adjustments are carried out in the same
manner.
It is
prudent to record the number of revolutions that the screw is turned in order to return to the
preset conditions if that is required.
The following instructions assume that the machine has been set up per the preceding instructions (the main
air is on, the plastic reservoir liner is filled and in place in the tank, and that the tank is adjusted to an
appropriate pressure).
1.
Loosen the Seal Nut that locks the Adjustment Screw with the appropriate open end or adjustable wrench
(Figure 15). If necessary, hold the screw with the correct hex driver to insure that it does not move. You
will hear a slight hissing sound caused by the air escaping once the Seal Nut is loose.
