P/N 237 502A

Converting an FP-200 Swirl Gun

to an FP-200 Extrusion Gun

WARNING: Allow only qualified personnel to perform the

following tasks. Observe and follow the safety instructions in

this document and all other related documentation.

The Nordson FP-200 gun, when combined with the appropriate

balance-assist devices, allows the operator to maintain a neutral wrist

position while manually applying hot melt adhesives and sealants to

horizontal substrates. Two versions of the FP-200 gun are available:

extrusion and swirl. Extrusion guns can meet a wide variety of bead

deposition requirements while swirl guns permit exceptional control of

spiral pattern density and size.

Nordson offers two conversion kits: One to convert an extrusion gun to a

swirl gun and one to convert a swirl gun to an extrusion gun. This

instruction sheet contains the procedures for converting a swirl gun to an

extrusion gun.

NOTE: This conversion kit is configured to convert FP-200 gun

Part Number (P/N) 234 896 (swirl gun) to P/N 234 897 (extrusion gun).

It does not accommodate any other FP-200 gun part numbers.

This instruction sheet contains the following procedures:

SPreparing to Convert an FP-200 Gun. Complete this procedure

before performing the conversion.

WARNING: Hot! Risk of burns! Hot applicator parts, splashed

hot melt material, and hot gun surfaces can cause severe

burns. Wear long-sleeved, heat-protective clothing, safety

goggles, and heat-protective gloves. Hot melt material may be

released forcefully.

WARNING: Risk of burns. System or material pressurized.

Air trapped in hoses and guns can spit out molten adhesive that

can cause severe burns. Failure to relieve hydraulic pressure

can result in serious burns. Relieve hydraulic pressure when

instructed to do so.

WARNING: Even when switched off, Nordson applicators,

hoses, and guns contain electrical potentials that can cause

death. Disconnect and lock out line voltage to the applicator

when instructed to do so.

1. Relieve hydraulic pressure (refer to the Relieving Hydraulic Pressure

procedure in the FP-200 gun product manual).

2. Switch the applicator circuit breaker to the OFF position.

3. Disconnect and lock out electrical power to the applicator.

4. Shut off the air supply to the gun.

5. Remove the heat shield from the existing gun as follows:

a. Remove the auxiliary guide handle.

b. Disconnect the extrusion and swirl air lines from the service block

and air manifold.

c. Remove the heat shield.

d. Reconnect the extrusion and swirl air lines. Do not reinstall the

auxiliary guide handle.

6. Remove the existing gun from the suspension system by

disconnecting the hose hydraulically and electrically and by

disconnecting the air line.

. Preparing to Convert an

FP-200 Gun

Swirl Gun to an FP-200 Extrusion Gun

E1997 Nordson Corporation

Issued 9/97

P/N 237 502A

CAUTION: The kit for converting a swirl gun to an extrusion

gun does not include a heat shield. To comply with

Underwriter’s Laboratory (UL), Canadian (C-UL), and

Conformité Européenne (CE) standards, heat shield

P/N 234 970 must be used on the converted extrusion gun.

The swirl gun heat shield is 19 mm (3/4in.) longer than the

extrusion gun heat shield and could obstruct the operator’s

visibility of the adhesive’s point of application.

Follow this procedure to convert an FP-200 swirl gun to an extrusion gun.

Figures 1 and 2 identify the components referred to in the procedure (for

clarity, the heat shield is not shown).

d. Use the socket head screws to secure the new module to the

service block. Torque the screws to 30 in-lb.

NOTE: For best results, torque the screws again after the applicator

reaches operating temperature.

NOTE: Nozzles must be ordered separately. Refer to Section 5,

Parts.

7. Install the extrusion gun heat shield as follows:

a. Disconnect the extrusion air line by unthreading the tube nut

at the male connector on the service block.

b. Wrap the cover around the module and service block and

fasten it.

c. Reconnect the extrusion air line.

8. Reinstall the auxiliary guide handle.

9. Go to Section 4, Restoring the System to Normal Operation.

Use this procedure to restore the applicator and converted gun to normal

operation.

1. Reconnect the gun to the suspension system by reconnecting the gun

and hose hydraulically and electrically, then reconnecting the gun to

the air supply.

2. Restore electrical power to the applicator.

3. Move the applicator circuit breaker to the ON position.

4. Let the unit and hose reach operating temperature.
