Overview
Theory of Heat Fusion
The principle of heat fusion is to heat two surfaces to a
designated temperature, and then fuse them together by
application of force. This pressure causes flow of the melted
materials, which causes mixing and thus fusion. When
the polyethylene pipe is heated, the molecular structure is
transformed from a crystalline state into an amorphous condition.
When fusion pressure is applied, the molecules from each
pipe end mix. As the joint cools, the molecules return to their
crystalline form, the original interfaces are gone, and the two
pipes have become one homogeneous pipe. The joint area
becomes stronger than the pipe itself in both tensile and pressure
conditions.
The principle operations include:
Clamping The pipe pieces held axially to allow all subsequent
operations to take place.
Facing The pipe ends must be faced to establish clean,
parallel mating surfaces perpendicular to the
centerline of the pipes.
Aligning The pipe ends must be aligned with each other to
minimize mismatch or high-low of the pipe walls.
Heating A melt pattern that penetrates into the pipe must be
formed around both pipe ends.
Joining The melt patterns must be joined with a specified
force. The force must be constant around the interface
area.
Holding The molten joint must be held immobile with a
specified force until adequately cooled.
Inspecting Visually examine the entire circumference of the joint
for compliance with standards established by your
company, customer, industry, federal, state, or local
regulations.
PH00363B-1-4-96
Each pipe manufacturer has a slightly different approach for
fulfilling the heating, joining, and holding phases, but the end
result is the same -- a fusion joint that is as strong or stronger than
the pipe itself.

Overview
PitBull No.14 Cart
The PitBull No.14 fusion machine can be mounted on a No.14
four wheel cart for mobility and movement along the pipe line.
There is a clamping wheel lock on the left rear wheel to prevent
rolling.
The cart is not designed for over-road towing.
Towing at speeds greater than 5 mph can
result in machine damage as well as injury.
Always transport the machine by flatbed truck
or similar means.
The tongue on the tow bar has a ring to slip over a ball hitch so
the machine can be conveniently maneuvered at the job site.
The cart has outrigger pipe supports that conveniently stow
under the cart when not in use.
The PitBull No.14 Fusion Machine can be mounted on the cart
in any one of three orientations. Older No.14 Fusion Machines
can be mounted in one orientation. The machine is secured
by two mounting posts and a sliding clamp block with an
adjustable clamping lever.
To mount the fusion machine on the cartslide the mounting block
toward the tow bar. Insert one edge of the fusion machine base
under the mounting posts. Slide the clamp block up against the
other edge and secure it with the adjustable clamping lever. To
disengage and swivel the adjustable clamping lever handle pull
up on it by pressing the button with a thumb.
PH01876-7-25-00
PH01891-7-25-00

Overview
Reversible Jaws & Levers
The No. 14 PitBull upper jaws and control levers are reversible
from one side to the other. This allow the machine to be operated
from either side. The jaws and clamp knobs can be removed by
using a pair of snap ring pliers to release the hinge pins.
The lever handles can be moved from one side to the other by
depressing their spring pins and pulling them out. Put the lever
in the desired socket and make sure its pin engages the hole. The
levers should be on the side opposite the clamp knobs.
Notice: When the top jaws are reversed they should be switched
between lower jaws so that the spring pins are both on the
outboard sides away from the facer blades.

Outrigger Pipe Supports
The PitBull No.14 cart comes equipped with two outrigger
pipe supports that can be used to help line up the pipe in the
machine. When not in use they are fastened with pins under
the cart.
To use the outriggers, simply remove attaching pins, pull
outriggers out and reinstall on the top front and back of the
cart with attaching pins.
The outriggers rest on adjusting screws that can be adjusted
up or down for proper pipe alignment. A wing nut on each
adjusting screw locks the screw setting in place.

Overview
Electric Facer
The facer is a McElroy Rotating Planer Block Design. The blade
holders each contain two cutter blades. The block rotates on ball
bearings and is chain driven (enclosed in lubricant) by a heavy
duty electric motor. When operating in a hazardous environment,
operate the facer manually.
Electric motors are not explosion proof.
Operation of these components in a hazardous
environment will result in explosion and death.
The armature brushes must be removed from the electric motor
when manually operating in a hazardous condition. Unscrew
the brushes from both sides of the motor. (Both brushes must
be removed). A 7/8" hex shaft allows for manual operation in
hazardous conditions.
The facer has a handle that latches into place on a guide bar.
The handle must be pulled out to unlatch and remove facer.
The electric facer is symmetrical and can be inserted from either
side.
The facer should be stored in the stand when not in use.
NOTICE: Never extend the blade beyond the inner or outer
circumference of the facer.

Overview
Heater
Heater is not explosion proof. Operation of heater
in a hazardous environment without necessary safety
precautions will result in explosion and death.
If operating in a hazardous environment, heater should be brought up
to temperature in a safe environment, then unplugged before entering
the hazardous atmosphere for fusion.
The heater has a green indicator light which will flash on and off.
This indicates that the controller is operating normally. If the green
indicator is not flashing then the controller may not be operating
properly. If this occurs, disconnect power and have the heater
repaired by a McElroy Authorized Service Center.
The heater temperature is controlled by a microprocessor. It has a red
indicator light on the handle at the bottom of the temperature scale.
When the heater is plugged in and preheating the light glows steadily
until the set temperature is reached. The light then goes off and on
slowly as the heater maintains temperature.
The heater body is not coated. Coated butt fusion heater adapters are
available for all butt fusion applications.
NOTICE: The heater should never be used without butt fusion heater
adapters installed.
To prevent a build-up of plastic pipe residue from accumulating on the
heater plates (loss of surface temperature and pipe sticking may result),
the heater plates should be cleaned with a non-synthetic cloth before
and after every fusion joint.

Operation
Positioning Pipe in Machine
Position the facer on the guide rods and lock into position. Using
lever handle, bring pipe ends together against the facer, watching
the gap between the facer stops and the pipe clamping jaws. Leave
enough gap so that proper face-off will be achieved when the facer
stops are bottomed out against the clamps. Tighten the pipe clamp
knobs by hand until firm resistance is felt. Do not over-tighten.
NOTICE: Thoroughly clean all dirt and debris from pipe ends before
facing.
TX00839-1-5-96
Facing the Pipe Manually
Turn facer handle counterclockwise and apply firm pressure on lever
handle. Continue facing until facer stops have bottomed out against
the clamping jaws. Stop rotation of facer. Move jaws apart.
Unlatch and remove facer. Remove shavings from pipe ends and
machine. Do not touch faced pipe ends.
Inspect both pipe ends for complete face off. If the face off is
incomplete, return to Loading Pipe Into Machine.
PH01870-7-25-00PH001869-7-25-00
TX01848-7-25-00
Electric Facer
The electric facer should be started before the pipe is pushed into
contact with the blades. Continue facing until the facer stops are
against the jaws then turn off the facer while continuing to hold
pressure closed on the lever until the facer stops completely.
Reverse force to the lever handle to move the pipe ends away
from the facer. Unlatch and remove the facer taking care not
to touch the pipe ends. Remove shavings from pipe ends and
machine. Do not touch faced pipe ends as this may contaminate
them.
If after facing any imperfections are visible on the ends of the pipe
move the pipe inward and reface.
Any time clamp knobs are tightened pipe ends should be refaced.

Operation
Check Alignment of Pipe
Bring the pipe ends together under sufficient force to overcome
any pipe drag or friction in the system. Check for alignment
and proper face off. If high/low (misalignment) exists, adjust by
tightening the clamp on the high side and reface the pipe.
NOTICE: When clamping, do not over-tighten the clamp knobs
because machine damage can result. Check to see if there is
space between the upper and lower jaws. If the two jaws are
touching, do not continue to tighten. Bring the pipe ends together
under fusion pressure plus drag to check for slippage. If slippage
occurs, return to Loading Pipe into Machine.
TX02477-3-30-05
Check Heater Temperature
Incorrect heating temperature can result in
questionable fusion joints. Check heater plates
periodically with a pyrometer and make
necessary adjustments.
Check heater surface temperature.
Refer to the pipe manufacturer's recommendations for proper
heater temperature.
IMPORTANT: The dial thermometer on the heater indicates internal
temperature which varies from the actual surface temperature.
The dial thermometer can be used as reference once the surface
temperature has been verified.

Inserting Heater
Heater Is Not Explosion Proof. This unit is not
explosion proof. Operation of heater in a
hazardous environment without necessary safety
precautions will result in explosion and death.
If operating in a hazardous environment, heater should be brought
up to temperature in a safe environment, then unplugged before
entering the hazardous atmosphere for fusion.
Use a clean non-synthetic cloth to clean the butt fusion heater
adapter surfaces.
Verify heater temperature by noting the reading on the dial
thermometer.
Insert heater between the pipe ends. The stripper bar downward
legs should be outside of the jaws. (not on top)

Heating the Pipe
With heater in position between the pipe ends, snap pipe ends
sharply against the heater to ensure alignment. Follow the pipe
manufacturer's recommendations for heating time and pressure.
Raise the locking cam into the engaged position while in the
heating cycle.
TX00842-1-8-96
Fusing the Pipe
After the heating cycle is completed, remove the heater and
quickly apply fusion force with the lever handle in accordance
with the pipe manufacturer's recommended fusion procedure or
appropriate joining standard. A torque wrench can be used when
a specified Interfacial Pressure is required. Hold this force for at
least 10 seconds.
After 10 seconds, the locking cams will assist by holding force
during the cooling cycle.
Failure to follow pipe manufacturer's heating
time, pressure and cooling time may result in a
bad joint.

Operation
Optional Use of Torque Wrench
When a specified Interfacial Pressure is required in the fusion
procedure, a torque wrench can be used.
IMPORTANT: Use a torque wrench with the No.14 PitBull place
an adapter in the lever socket (Part # 410802). A 1/2" drive
100 ft-lb 15.0" torque wrench is required when using the torque
wrench adapter. Using a torque wrench of a different length will
result in different forces from the torque reading.
To calculate the proper torque reading see Section "Determine
Fusion Force."
Add the torque required to overcome Drag (the force required to
move the pipe at or near the point of fusion) to the torque reading
to assure the proper joining force. This should be determined
prior to inserting the heater.
Failure to follow pipe manufacturer's heating
time, pressure and cooling time may result in a
bad joint.

Heater Indicator Light
The heater has a green indicator light which will flash on and off.
This indicates that the controller is operating normally. If the green
indicator is not flashing then the controller may not be operating
properly. If this occurs, disconnect power and have the heater
repaired by a McElroy Authorized Service Center.
The heater has a red indicator light on the handle at the bottom
of the temperature scale. When the heater is plugged in and
preheating the light glows steadily until the set temperature is
reached. The light then goes off and on slowly as the heater
maintains temperature.
If the heater is not operating properly, the control will attempt to
turn the heater off and the indicator light will flash rapidly. If this
occurs, disconnect the power and take it to a McElroy Authorized
Service Center for repair.
