NOTE: Solenoid valves must be rated for the output voltage of the triggering

device. Make sure the ratings match.

3. Thread a 0.75-0.34 mm

(18-22 AWG) three‐conductor cable through the

housing strain relief and then connect the positive and negative leads to

terminals 1 and 2 (polarity does not matter) and connect the ground wire

to the ground terminal. The terminal positions are marked on the bottom

of the terminal block.

4. Snap the terminal block back into its housing.

5. Align the gasket on the terminal block housing, plug the terminal block

into the solenoid valve, and secure it with the screw removed earlier.

6. Connect the three‐conductor cable to the triggering device. Refer to the

instructions that came with the triggering device.

Connecting the Hose

Refer to the user's guide shipped with the hose for detailed hose installation

guidelines.

1. Do one of the following:

 If an in‐line filter is to be used, remove the hose connector

preinstalled on the applicator and then install the in‐line filter. Refer to

the instruction sheet provided with the in‐line filter.

 If no in‐line filter is used, check the tightness of the preinstalled hose

connector.

See Figure 7.

2. Connect the hose swivel fitting to the applicator hose connector. Use two

wrenches to tighten the hose fitting.

3. Connect the applicator cordset to the hose.

4. Connect the hose to the melter. Refer to the hose user's guide and/or the

melter product manual as needed.

5. Go to Flushing the applicator.

Flushing the Applicator

Before operating the system, the applicator must be flushed to remove

residue left over from factory‐testing. Install the nozzles after this procedure.

For information on installing nozzles, refer to Maintenance.

NOTE: This equipment is factory tested with Nordson Type R fluid

containing polyester adipate plasticizer. Certain adhesives may react with the

Type R fluid residue to form a solid gum that can be difficult to remove.

Consult with the adhesive supplier to determine the compatibility of the

adhesive with Type R fluid.

1. Disconnect or turn off the solenoid valve triggering device.

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

the melter manual for the startup procedure.

3. Place a drain pan under all applicators.

4. Flush according to the type of applicator module being used:

For standard Applicators

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

the solenoid valve(s).

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

residue.
