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 21.
3. Verify shaker inlet (K) is at the bottom of the adhe-
sive pellets container that is filled with hot melt
adhesive pellets. See FIG. 1 on page 16.
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).
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 37.
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 FIG.1
on page 16.
b. Check pressure gauges (D, F) to verify vacuum
transfer and pump air pressures are set as
desired. See FIG. 1 on page 16.
c. If using Automatic Refill, see Automatic Refill
on page 40.
d. If using Manual Refill, see Manual Refill on
page 39.
e. Verify applicators are closed.
4. Press to enable the heaters and pump.
NOTE: If using the Schedule function, the heaters and
pump will be enabled automatically at the set time. You
will not need to press if using the Schedule func-
tion unless you wish to enable the heating system
before the set time.
NOTE: When system is up to temperature, the pump will
begin running automatically. It will stall at pressure
unless an applicator is open. Material will be dispensed
whenever an applicator is open after the system is up to
temperature.
