Shutdown

PUR adhesive reacts with moisture in the air therefore 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 syringe/cartridge in the applicator. This will retain the seal and

minimize the exposure to air.

2. The next morning, follow the Daily Start-up and Operation procedure

earlier in this section to install a new syringe/cartridge.

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. Ensure that the

collection pan is large enough to shield the operator from the spray.

2. Place the controller purge switch in the on position until all adhesive is

dispensed from the syringe/cartridge, then place the switch in the off

position.

3. Flexseam applicator only

a. Open the applicator cap, and without putting pressure on the syringe

remove the air cap.

b. Use a pick to remove any hardened adhesive from the syringe.

c. Install the air cap and close the latch.

4. Remove the applicator nozzle and purge again to ensure that all

adhesive is dispensed.

CAUTION! Ensure that the flushing material is compatible with the PUR

adhesive being used. Refer to the SDS for both the adhesive and the flushing

material.

5. Load a flush syringe/cartridge into the applicator.

6. Purge again until a clean flow of flush material is achieved. Leave some

flush material in the syringe/cartridge.

7. Reinstall the nozzle and purge the system again to flush all PUR

adhesive out of the nozzle. Leave some flush material in the

syringe/cartridge.

8. Turn off the air supply.

9. Turn off the controller.

10. Turn off the robot.
