3. Fill the funnel with adhesive pellets.
4. Refill the funnel as needed to maintain the required
dispense rate.
5. When finished dispensing for the day, dispense into
a waste container until the material level is down to
the smallest diameter section of the funnel then con-
tinue purging material through the valve for an addi-
tional 75 pump strokes.
NOTE: This will lower the adhesive level within the feed
cap to the correct level to prevent any issues upon
startup the following production day.
NOTE: Pump strokes can be monitored on the Mainte-
nance screen, or by counting pump changeovers. To
count pump changeovers, listen to the air motor exhaust
pulses; two exhaust pulses equals one pump cycle (two
strokes).
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 14.
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
IG
. 1 on page 8.
NOTE: The shaker inlet must be completely covered in
adhesive pellets in order for it to effectively pull pellets
into the tube.
4. If not already set, use vacuum transfer air pressure
regulator (E) to adjust vacuum transfer air pressure
setting to 40-100 psi (280-690 kPa, 2.8-6.9 bar).
Recommended setting is 60 psi (414 kPa, 4.1 bar).
See F
IG
. 1 on page 8.
NOTE: The system will automatically transfer the pellets
to the system as necessary.
Dispense
NOTE: Only hot melt adhesive pellets can be used in
the InvisiPac system.
1. If the system is empty or has air in the lines, perform
Initial Startup and Prime procedure on page 26.
2. If main power switch is OFF, turn main power switch
ON .
NOTE: The main power switch should be left ON at all
times when using the Schedule function.
3. Prepare for dispensing:
a. Verify air inlet ball valve (J) is open. See F
IG
. 1
on page 8.
