F IG . 1 on page 8.
NOTE: Vacuum transfer will not begin operating until
pump reaches operating temperature.
NOTE: A new system may have residual oil due to test-
ing 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 21 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 oper-
ating temperature. See Select ADM Settings on
page 21 for instructions.
11. Use separate gun controller to open the guns and
keep them open.
12. With the guns open and the system up to tempera-
ture, slowly increase pump air pressure until the
pump begins to run very slowly. Approximately 20
psi (140 kPa, 1.4 bar) should be sufficient.
NOTE: Operation may be erratic below 20 psi (140 kPa,
1.4 bar).
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:
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 dis-
pense 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. Per-
form service to automatic feed system as soon as possi-
ble 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 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 phillips head screws then remove the
funnel cap from the funnel.
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.
NOTICE
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.
