Automatic Refill - Graco 24T918 Instruction Manual

It is recommended to maintain a minimum flow rate of
1.5 lb/hour to prevent material from melting within the
feed cap and funnel. If production rate is below
1.5 lb/hour or system sits at temperature without dis-
pensing for extended periods of time, use manual refill-
ing with caution. System flow rate can be monitored by
enabling the Diagnostic screen.
1. On the System 3 screen (in the Setup screens),
select "Manual" from the Refill mode dropdown.
2. Remove the two bolts from the funnel bracket, then
remove the top portion of the funnel.

5. Refill the funnel as needed to maintain the required
dispense rate.
6. When finished dispensing for the day, dispense into
a waste container until the material level is down to
the melter core. See F
NOTE: This will lower the adhesive level within the fun-
nel cap to the correct level to prevent any issues upon
startup the following production day.

Automatic Refill

The system uses automatic refill by default. If the auto-
matic refill system is malfunctioning and cannot immedi-
ately be fixed, Manual Refill can be used.
To use automatic refill:
1. On the System 3 screen (in the Setup screens),
select "Automatic" from the Refill mode dropdown.
2. Verify shaker and tube are connected to the system.
See Attach Components on page 17.
3. Verify shaker inlet (K) is at the bottom of the adhe-
sive pellets container that is filled with hot melt
adhesive pellets. See F
NOTE: The shaker inlet must be completely covered in
adhesive pellets in order for it to effectively pull pellets
into the tube.
