Adding Adhesive
The adhesive level should be maintained at 13mm to 100mm (1/2” to 4”) from the top of the hop-
per. Where applications demand a high output volume of adhesive, add small amounts of adhesive
frequently. Adding large amounts of adhesive to an almost empty hopper will lower the temperature
of the adhesive in the hopper and may cause the ASU to fall below its READY setpoint.
Changing the Adhesive Formula
If a different adhesive formulation from the one being currently used is needed, the system will
have to be flushed if the two formulations are incompatible. See page 6-3 of this manual for the
proper flushing procedure. When in doubt about adhesive compatibility, flush your system.
WARNING HOT ADHESIVE
Do not overfill the hopper (melt tank) since adhesive generally expands as it
melts and a full hopper will overflow.
CAUTION: Using adhesive with viscosity over 50,000 centipoise could cause
motor stall and/ or pump failure.

100-120 VAC 1800 @ 120VAC 600 @ 120VAC 370 @120VAC 1200 @ 120VAC 830 @ 120VAC

Wattage Available for
All Hoses and Heads
Notes:
1. Assume 33 Watts per foot of hose, #6 hose at 120VAC or 240VAC.
2. Assume 100 Watts per inch of head width, at 120VAC or 240VAC.
3. The power available for any one hose or head is 720 Watts at 120VAC or 1440 Watts at 240VAC.
4. At reduced voltage, less wattage is available. For example: 120 volt equipment operated on 100
volts or 240 volt equipment on 200 volts, will develop wattage 31% lower than the wattage available
at 120 or 240 volts.
