Overview
Overview
The valve uses the air-opened, spring closed mode
of operation. It uses a three-way exhausting solenoid
to control the piston inside the valve. Fluid is filtered
through the manifold filter before entering the valve
fluid inlet port.
When air moves the piston and rod from its seat, it
opens the fluid outlet. When the air shuts off, the
spring pushes the piston and rod into its seat and
closes the fluid outlet.
The gun should be rigidly mounted and remotely
operated by a melter system and triggering device.
Themeltersystemprovidespressurizedfluidtothe
valve. The triggering device controls the fluid flow by
opening and closing the solenoid valve.
Figure 2 Air and Fluid Flow

Fluid
Grounding
The equipment must be grounded to reduce the
risk of static sparking. Static sparking can cause
fumes to ignite or explode. Grounding provides an
escape wire for the electric current.
•Pump: follow manufacturer’s recommendations.
•Dispense applicator: grounded through electrical
connection.
•Air compressor: follow manufacturer’s
recommendations.
•Fluid supply container: follow local code.
•Solvent pails used when flushing: follow local
code. Use only conductive metal pails, placed
on a grounded surface. Do not place the pail
on a nonconductive surface, such as paper or
cardboard, which interrupts grounding continuity.
•To maintain grounding continuity when flushing or
relieving pressure: ensure mounting manifold and
electrical power connector are grounded properly.

Installation
Installation
Mounting
Mount manifold on a 1/2 in. (12 mm) diameter bar
using mounting clamp (H) to hold the gun assembly
in place and ensure adhesive is applied properly.
NOTICE
To prevent heat transferring into other components
of the packaging line, ensure that the insulator is
installed.
1. Usea5mmAllenwrenchtoloosenthemounting
clamp and slide the gun assembly on the
mounting bar.
2. Tighten the mounting clamp.
Note
Provide enough room to access sides of
applicator for maintenance and repair.

installation guidelines.
4. Connect the hose cordset to melter. See the
heated hose manual for installation guidelines.
Connect Solenoid Valve
1. Connect 3/8 in. diameter air supply tubing to a
clean, dry, and non-lubricated air supply and to
the push-to-connect air inlet fitting (L).

Figure5 AirInletFitting
2. Connect solenoid valve to 24 VDC or 110 VAC
signal. See Connect Triggering Device, page 10.
For applicators without a supplied solenoid valve:
• Use solenoid valves with an override switch.
• Ensure that your solenoid valve is connected to the
manifold with tubing rated for 400°F(204°C).
• Ensure the solenoid valve is rated for
high-temperature applications.

Installation
Connect Triggering Device
Identify if your model uses a 24 VDC or 110 VAC
solenoid valve. Connect solenoid valve to 24 VDC
or 110 VAC signal.
Improper electrical connection can result in electric
shock. All electrical wiring must be done by a
qualified electrician and comply with all local codes
and regulations.
1. Loosen the mounting screw and disconnect the
electrical connector (N) from the solenoid valve
(J). Set the gasket and screw aside.

2. Insert a small screwdriver where the mounting
screw was removed and gently press the
electrical connector (P) out of the electrical
connector housing (N).
3. Thread a three-conductor cable through the strain
relief. Connect the positive and negative wires to
terminals 1 and 2 on the electrical connector (P).
Connect the ground wire to the ground terminal.

4. Reassemble the electrical connector (P) and
housing (N). Retighten strain relief.
5. Place the gasket on the housing and connect the
electrical connector into the solenoid valve (J)
with the mounting screw. See Fig. 6.
Prime Before Using Equipment
The equipment was tested with lightweight oil, which
is left in the fluid passages to protect parts. To avoid
contaminating your fluid with oil, prime the equipment
with hot melt until all of the oil is pushed out before
using the equipment. See Flush, page 10.
Flush
1. Disconnect or turn off the device which triggers
the solenoid valve.
2. Heat the system to working temperature.
3. Place waste container under the gun to catch the
adhesive.
4. Ensure the nozzle is removed.
5. Press the manual override switch (S) to manually
trigger the solenoid valve.
6. Dispense hot melt (adhesive) until it is clean.

Install Nozzle
Use 1/2 in. wrench to install nozzle. See
Kits and Accessories, page 30.
Operation
Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
This equipment stays pressurized until pressure
is manually relieved. To help prevent serious
injury from pressurized fluid, such as skin injection,
splashing fluid and moving parts, follow the
Pressure Relief Procedure when you stop spraying
and before cleaning, checking, or servicing the
equipment.
1. Depressurize system.
2. Close the bleed-type master air valve.
3. Actuate the applicator repeatedly until no fluid
flows.
Material inside the module and hose may still
be near setpoint temperature. Wear protective
clothing to avoid severe burns.
4. If you suspect the module nozzle is clogged,
remove nozzle and then actuate the module to
relieve pressure.
5. If you suspect the module or fluid hose is
clogged or that pressure has not been fully
relieved after following the steps above, VERY
SLOWLY loosen inlet fitting, inlet filter, or hose
end coupling to relieve pressure gradually,
then loosen completely. Clear hose or module
obstruction.
6. Turn off air pressure to the solenoid valve.
