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

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.

Maintenance

The following table provides the recommended schedule for applicator

maintenance. Detailed procedures for weekly and semi‐annual maintenance

tasks are provided.

Frequency Task Notes

Daily Remove hot melt material and char

from the exterior of the applicator

assembly.

Weekly Clean the applicator nozzle(s). A, B

Semi‐annually Inspect the applicator wiring.

NOTE A: Use a nozzle cleaning kit, P/N 901915.

B: Process‐specific nozzle performance history may indicate the need for

more or less frequent nozzle cleaning.

Cleaning Nozzles

Applicator nozzles may become clogged when char, a by‐product of

overheating the hot melt material, becomes lodged in the nozzle. The use of

an in‐line or integral filter will significantly reduce nozzle clogging.

1. Heat the applicator to operating temperature.

2. Disable the applicator. Refer to Safety.

3. Remove nozzles as shown in Table 4.

Table 4 Nozzle Removal and Installation Procedures
