Overnight and Long-Term Shutdown Procedures
Because PUR adhesive reacts with moisture in the air, exposure of the PUR
adhesive in the system to air must be minimized. The procedures below
represent the best practices for overnight or long‐term (longer than overnight)
shutdown.
Overnight Shutdown
1. Shut down the system and allow the applicator to cool, leaving the
current cartridge in the applicator . This retains the seal and minimizes
the exposure to air.
2. The next morning, follow the Daily Startup and Operation procedure
earlier in this section to replace a new cartridge. Refer to
Replacing the Cartridge on page 5‐6 for more information.
Long‐Term Shutdown
1. Place a large collection pan under the applicator.
WARNING! Risk of burns. When the last drops of adhesive are being
purged, the pressurized air will cause some adhesive spray. Make sure that
the collection pan is large enough to shield you from the spray.
2. Either touch the Purge button from the controller's Home screen, or from
the the robot, until all adhesive is dispensed from the cartridge.
CAUTION! Make sure the flushing material is compatible with the PUR
adhesive being used. Refer to the SDS for both the adhesive and the flushing
material.
3. Load a flush cartridge in the applicator as follows (see figure at left):
a. Remove the applicator air cap (1) and remove and discard the
adhesive cartridge (2).
b. Remove the caps from both ends of a 30cc flush cartridge(2).
c. Insert the flush cartridge in the applicator, with the tapered end
pointing down.
d. Reinstall the applicator air cap.
4. Purge until a clean flow of flush material is achieved.
5. Leave the flush cartridge in the applicator.
6. Turn off the air supply.
7. Turn off the controller.
8. Turn off the robot.
