Flush
NOTE: This procedure describes how to flush one hose
at a time for maximum effectiveness.
See the hot melt adhesive technical data sheet or
MSDS for the recommended cleaning fluid. Contact the
hot melt supplier if the technical data sheet or MSDS is
not available.
1. Perform Drain the System on page 33.
2. If the heating system is enabled, press to dis-
able the heaters and pump.
3. Loosen hose clamp securing funnel assembly to air
motor bracket then remove funnel assembly from
system. Keep 1.3 in. (33 mm) clear tube and funnel
cap attached to funnel.
4. Loosen upper clamp then remove plastic melter
cap. Keep fill sensor attached to cap.
5. On the System 3 screen (in the Setup screens), ver-
ify the Refill Setting is set to “Manual”.
6. Change the melter, heated hoses, and guns tem-
perature settings to the high temperature hot melt
cleaning fluid manufacturer’s recommended tem-
perature.
7. Verify the system air inlet ball valve is closed and
pump air pressure is set to 0.
8. Allow the system to heat or cool to the cleaning fluid
manufacturer’s recommended temperature.
9. Fill melter with high temperature rated hot melt
cleaning fluid. See hot melt adhesive material sup-
plier for recommended hot melt cleaning fluids.
Fluid level should be 1/2 in. (12.7 mm) from the top
of the melter.
10. Disconnect one hose from its gun manifold.
NOTE: Keep all guns closed throughout this procedure.
11. Route the disconnected hose to a waste container.
12. If heating system is disabled, press to enable
the heaters and pump.
13. Wait for the melter temperature to reach the hot
melt cleaning fluid manufacturer’s recommended
temperature.
NOTE: The pump will not run because the system air
inlet ball valve is closed.
14. Once the required melter temperature is reached,
let the hot melt cleaning fluid “soak” in the melter at
temperature for the duration specified by the hot
melt cleaning fluid manufacturer.
To prevent fire and explosion, use the adhesive manu-
facturer’s recommended cleaning fluid.
• Never exceed the cleaning fluid’s rated
temperature.
• Never flush your system or clean any aluminum
components with halogenated hydrocarbon
cleaning solutions.
To prevent severe burns, wear protective clothing.
To prevent fire and explosion, never exceed the
cleaning fluid’s rated temperature.
