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.

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