There are two visual cues to indicate that it is time to refill the fluid in the sealer.
Liquid in the bottle is at or below the refill line
A warning message appears on the display
Follow these steps to refill the sealer bottle:
Remove the bottle from its holder on the system and place it on a flat surface
Unscrew and remove the pressure-sensitive top from the bottle
Pour sealant into the bottle until it reaches the fill line
Screw the pressure-sensitive top securely back onto the bottle
Wipe off any fluid that spilled
Put the bottle back into its holder
Note: If filling the sealer for the first time, or if the sealer was completely empty, allow time for solution to soak through the sealer mechanism before processing material.
