5. The adhesive hoses are connected to the f ilter manifolds at the back of the machine (see illustra-
tion on the next page).
On a two or four-hose machine, the hose electrical plugs are connected to the bank of receptacles #1
to 4. The optional auxiliary zone cables, if used, are connected to the right bank of receptacles #1 to
4. On a six-hose machine there are no auxiliary zones and hoses #5 and 6 are connected to two re-
ceptacles on the r ight bank.
The left filter manifold (viewed from t he back of the machine) corresponds to pump #1 and the right
one to pump #2. Each manifold has four adhesive ports for connection of hoses and optional pres-
sure gauges or pressure transducers.
When using a single pump, remove the divider plug from the corresponding manifold and connect
hose #1 to port #1 and connect the corresponding electrical plug to hose receptacle #1. Connect hose
#2 (if used) to port #2 and its plug t o receptacle #2.
When using a dual pump, leave the divider plug in place and connect hoses corresponding with the
first glue stream to ports #1 and 3. Connect hoses corresponding to the second glue stream to ports
#2 and 4.
Use the same procedures for the second pump and filter manifold, if applicable.
Install hoses with a bend radius of n o less than 8 inches. Maintain an air space between hoses to
avoid hot spots. Use proper belting-type support. Avoid pinching, clamping, squeezing or anything
else that would compress the insulation around the hose, resulting in hot spots which shorten hose
life.
6. Install the hose manifold (filter block) outlet cover by sliding it into place and attaching with the
two screws provided.
Adding Adhesive
The adhesive level in the melt tank should be maintained at 25mm to 100mm (1” to 4”) from the top
of the hopper. Where applications demand a high output volume of adhesive, add small amounts of
adhesive frequently. A dding 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 Chapter 6 of this manual for the proper
flushing procedure. When in doubt about adhesive compatibility, flush your system.
CAUTION: Using adhesive with viscosity o ver 50,000 c entipoise could cause
motor stall and/ or pump failure.
