For all Applicators except zero and reduced cavity applicators

a. Ensure that all nozzles are removed.

b. Dispense hot melt material from the applicator by manually triggering

the solenoid valve(s).

c. Stop dispensing when the flow of hot melt material is clear and free of

residue.

For zero and reduced cavity Applicators

a. Relieve system hydraulic pressure and disable the applicator. Refer

to Safety.

b. Remove the applicator module by removing the two mounting screws

from the front of the module.

c. Re‐pressurize the system; then place the applicator into operation.

d. Dispense hot melt material from the port(s) in the applicator body,

increasing the pump output in small increments.

e. Stop dispensing when the hot melt material is clear and free of

residue.

5. Check for leaks between the applicator, hose, and melter.

6. Do one of the following:

Pivoting the Applicator Modules

Before operating the system, pivot the applicator module to the required

position for application of variable pitch patterns.

NOTE: The applicators have typically pivot marks on the rotating disk that

are spaced in increments of 5. The reference marks are also provided on

the rotating disk.

1. Relieve the system hydraulic pressure. Refer to Safety.

1 Pivot marks

2 Reference marks

Fig. 8 Marks on the MiniBlue ll applicators

CAUTION: Do not pivot the the applicator modules if the applicator is cold.

Pivoting the applicator modules when the applicator is not heated will

damage the O‐rings.

WARNING: System pressurized! Relieve system pressure before adjusting

the applicator. Failure to relieve system pressure can result in personal

injury.

2. Loosen the two hexagon head screws located on the back of the

applicator body.

3. Pivot the applicator modules to the desired position.

4. Tighten the hexagon head screws.

Operation

The applicator is now ready for operation.

Starting the System

Follow this procedure to start the system.

CAUTION: Risk of equipment damage. Nordson Corporation recommends

turning off the applicator air supply during system startup to prevent

unexpected pressure buildup in the module and applicator body caused by

the expansion of the cold adhesive as it melts.

1. Make sure the applicator air supply is turned off.

2. Turn on the melter and allow it to reach operating temperature. Refer to

your melter manual for details on the startup procedure.

3. Turn on the applicator air supply.

4. Turn on the solenoid valve power supply, enable any triggering devices,

and start the production line.
