Grounding
Attach Components
The equipment must be grounded to reduce the risk
of electric shock. Improper grounding can cause
electric shock. Grounding provides an escape wire
for the electric current.
The InvisiPac system is equipped with a ground terminal. Have a qualified electrician ground the system using
this terminal. See Connect Electrical Cord on page 18.
To reduce the risk of electric shock, do not connect
electrical cord until after this Attach Components
procedure is complete.
1. Place the base system in the desired operating
location and orientation. See Location on this page.
•
The bottom of the electrical enclosure has holes for
securing the InvisiPac system to a surface. The
holes are accessible through the bottom access
doors in the three rear walls of the electrical enclosure.
•
To install the InvisiPac system in place of a
non-Graco hot melt system, purchase Adapter
Plate, 24R083. See installation instructions on
page 83.
•
To raise the system to eye-level, purchase System
Stand, 24R088. See installation instructions on
page 83.
Location
Ambient temperature must be 32-120°F (0-49°C).
The supplied vacuum transfer hose length is 10 ft (3 m).
The maximum vacuum transfer hose length available is
30 ft (9.1 m). The adhesive pellets container must be
located within reach of the vacuum transfer hose and no
more than 30 ft (9.1 m).
The gun(s) must be located no more than 25 ft (7.6 m)
from the melter.
Place the base system on a surface that is eye-level for
easiest operation. Use System Stand, 24R088, to
install system at eye-level. See page 83.
If installing the system in place of a non-Graco hot melt
system, purchase Adapter Plate, 24R083. See
page 83.
NOTE: Supplied vacuum transfer hose must reach from
the system to the adhesive pellets container. Supplied
heated hose must reach from system to gun(s).
2. Install vacuum transfer inlet funnel (G3) onto system. See FIG. 7.
a. Slide funnel through the bracket connected to
the air motor.
Optional 30 Gallon Vibrating Hopper, 24R136, available (purchase separately). See page 84.
b.
To make repairing the system easier, locate the system
so that all sides are easily accessible and have sufficient
lighting.
Position the funnel so the funnel inlet faces the
desired direction.

5. Open system air inlet ball valve.
Overview
The system includes a vacuum transfer system that
pulls the adhesive pellets into the system as needed.
Once melted, the adhesive enters the pump where it is
pumped into the heated hoses then to the heated guns.
The gun then briefly opens to dispense the desired
quantity of adhesive.
Even though the system rises to operating temperature
quickly, there is a Schedule function in the ADM that
eliminates waiting for the system to heat up. The Schedule function automatically enables the heating system at
the user-specified times so the system is ready to dispense when a shift begins. The Schedule function also
disables the heating system at user-specified times to
ensure the heating system is disabled when not being
used.

13. Continue running the pump until clean, air-free
material is dispensed from each gun.
14. When each gun is fully primed, adjust pump to
desired pressure setting:
To prevent fire and explosion, never exceed the
cleaning fluid’s rated temperature. If the system was
just flushed, residual cleaning fluid is still in the
system until the system is primed with adhesive. Do
not raise temperature above cleaning fluid rated
temperature until system is primed with adhesive.
NOTE: A new system may have residual oil due to testing at the factory prior to shipping. To prevent smoking,
make sure to perform the following step.
8. On new systems only: temporarily adjust the melter
temperature to 250°F (121°C). See Select ADM
Settings on page 20 for instructions.
9. Press
to enable the heaters and pump.
NOTE: When system is up to temperature, the pump will
be activated automatically but will not start because
there is no air pressure supplied to the pump.
NOTE: When the melter is up to temperature, the
auto-fill function will initiate to fill the funnel with pellets.
10. On new systems only: After the melter has reached
250°F (121°C) and the funnel is filled with pellets,
set the melter temperature back to the desired operating temperature. See Select ADM Settings on
page 20 for instructions.
11. Use separate gun controller to open the guns and
keep them open.
NOTICE
a. Adjust pump pressure to between 20-100 psi
(140-690 kPa, 1.4-6.9 bar).
b.
Use separate gun controller to repeatedly open
and close each gun while inspecting the dispense pattern.
c.
Repeat until desired dispense pattern is
achieved.
Manual Refill
NOTE: Use Automatic Refill whenever possible. The
system uses Automatic Refill by default and must be
manually changed to Manual Refill. Only use Manual
Refill if the Automatic Refill system is not functioning
properly and cannot be fixed in a timely manner. Perform service to automatic feed system as soon as possible to limit debris buildup on feed cap.
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 dispensing for extended periods of time, use manual refilling 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 phillips head screws then remove the
funnel cap from the funnel.
In the following step, to prevent damage to the pump
due to pump cavitation, do not supply more than 20 psi
(140 kPa, 1.4 bar) air pressure to the pump until the
system is fully primed.
12. With the guns open and the system up to temperature, slowly increase pump air pressure until the
pump begins to run very slowly. Approximately 20
psi (140 kPa, 1.4 bar) should be sufficient.

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 continue purging material through the valve for an additional 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 Maintenance 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).
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

Operation Tips to Minimize
Charring
Set the Pump Idle Time to System Inactive function
on the System 3 screen to lowest value that will not
interfere with normal operation. This feature automatically disables the heating system if the pump is idle for
longer than the preset amount of time. Disabling the
heating system minimizes adhesive degradation and
limits char formation.
When possible, utilize the Schedule function, see
page 27, to automatically enable and disable the heating system in accordance with your production schedule. This will ensure adhesive spends as little time at
temperature as possible. Less time at high temperature
ultimately means less adhesive degradation and less
char.

NOTE: Some adhesives have different melting points.
The first temperature tried should be approximately half
of the dispensing temperature. If dispensing at 400°F
(204°C), first try 200°F (93°C) then increase in 20°F
(11°C) increments. If dispensing at 250°F (121°C), first
try 125°F (52°C) then increase in 20°F (11°C) increments.
NOTE: To ensure the adhesive is a gel, not a liquid, do
not remove inlet filter cap (215) when the temperature is

30 Gallon Vibrating Hopper, 24R136
Hopper includes a shaker to ensure the adhesive pellets maintain a level surface at all times. Without this, the adhesive pellets can stick together, preventing them from continuously covering the vacuum transfer system’s inlet. This
would cause the vacuum transfer system to be unable to transfer the adhesive pellets.
