Converting an FP-200 Extrusion Gun to
an FP-200 Swirl Gun
WARNING! Allow only qualified personnel to perform the following tas s.
Follow the safety instructions in this document and all other related
documentation.
Introduction
This conversion it provides instructions to convert an FP-200 extrusion gun
(P/N 234897) to an FP-200 swirl gun (P/N 234896). It does not
accommodate any other FP-200 gun part numbers.
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 its: 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 an extrusion gun to a
swirl gun.

Preparing to Convert an FP-200 Gun
WARNING! Hot! Ris 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: Ris 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 loc out
line voltage to the applicator when instructed to do so.
1. Relieve hydraulic pressure (refer to the Relieving ydraulic Pressure
procedure in the FP-200 gun product manual).
2. Switch the applicator circuit brea er to the OFF position.
3. Disconnect and loc 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 air line from the service bloc .
c. Remove the heat shield.
d. Reconnect the extrusion air line. 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.

Converting an FP-200 Extrusion Gun to a Swir Gun
CAUTION! The it for converting an extrusion gun to a swirl 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 234 965 must be used on the converted swirl gun. The extrusion gun
heat shield is 19 mm (
3
/
4
in.) shorter than the swirl gun heat shield and thus
cannot sufficiently cover a swirl gun as required to meet UL, C-UL, and CE
safety requirements.
Follow this procedure to convert an FP-200 extrusion gun to a swirl gun.
Figures 1 and 2 identify the components referred to in the procedure
(for clarity, the heat shield is not shown).
See Figure 1.

Disassembling the Extrusion Gun
Ma e sure you have completed the Preparing to Convert an FP-200 Gun
procedure before proceeding.
See Figure 3 for the following procedure.
1. Unthread and remove the outlet air line swivel fitting from the outlet air
line universal elbow.
2. Disconnect the mounting brac et from the gun mounting plate.
3. Disconnect the outlet air line universal elbow from the bul head fitting
and set it aside. It will be used later.
4. Disconnect the bul head fitting and mounting brac et from the extrusion
air line universal elbow.
5. Extract the bul head fitting from the mounting brac et.

Assembling the Extrusion Gun
See Figure 4 for steps 1 through 5.
1. Reinstall the mounting brac et on the opposite side of the gun mounting
plate. Ensure that the mounting brac et is positioned as shown in
Figure 4.
2. Install the air regulator in the mounting brac et by removing one loc ing
nut and washer, inserting the regulator through the hole in the mounting
brac et, then replacing and tightening the loc ing nut and washer.
Ensure that the T manifold inlet is facing away from the gun mounting
plate.
NOTE: For best results, lightly coat the connector threads of the
universal elbows, T manifold, outlet air line swivel fitting, and #10–32
connector with an anaerobic sealant before assembling them as directed
in steps 3 through 5 and step 8.
CAUTION! Do not overtighten fittings when performing the following steps.
Overtightening can cause the connectors to crac and snap off.
Finger-tightening, combined with the use of a sealant, is usually sufficient.
CAUTION! Only a small amount of sealant is required. Do not overcoat
connectors with sealant. Overcoating can cause excess sealant to migrate
into the air passages.
3. Attach the extrusion air line universal elbow to the T manifold.
4. Thread the T manifold into the air regulator, then thread the outlet air line
swivel fitting into the T manifold. Carefully tighten the fittings.

10. Install the new CF-200 wide pattern module on the service block as
follows:
a. Remove the old module.
b. Lubricate the new module's o-rings.
c. Wipe off any hot melt material on the service block, especially around
the air passages.
d. Apply anti-seize lubricant to the two module socket-head screws.
CAUTION: Do not overtighten. Overtightening can strip the threads.
e. 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 Parts.
11. Install the swirl gun heat shield as follows:
a. Disconnect the swirl and extrusion air lines by unthreading the tube
nuts at the male connectors on the service block and air manifold.
b. Wrapthecoveraroundthemoduleandserviceblockandfastenit.

Restoring the System to Norma 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 brea er to the ON position.
4. Let the unit and hose reach operating temperature.
5. Retighten gun-to-hose and gun-to-applicator fittings.
6. Chec for low pressure lea s at the gun-to-hose fitting.
7. Turn the air supply on.
8. While slowly restoring air pressure to the gun to 379.2 Pa (55 psi), chec
for lea s. Retighten fittings as necessary.
9. Resume normal operation.
