SAFETY ALERTS
Do not operate this equipment until you have carefully read and understood all sections
of the machine manual and all other equipment manuals that will be used with it. Please
be sure you are familiar with the standard to which you will be fusing. Your safety and
the safety of others depends upon care and judgment in the operation of this equipment.
Follow all applicable federal, state, local and industry specific regulations. McElroy cannot
anticipate every possible circumstance that might involve a potential hazard. The warnings
in this manual and on the machine are therefore not all-inclusive. You must satisfy yourself
that a procedure, tool, work method or operating technique is safe for you and others. You
should also ensure that the machine will not be damaged or made unsafe by the method
of operation or maintenance you choose.
GENERAL SAFETY
Safety is important. Report anything unusual that you notice during set up or operation.
LISTEN for thumps, bumps, rattles, squeals, air leaks, or unusual sounds. SMELL odors like
burning insulation, hot metal, burning rubber, hot oil, or natural gas. FEEL any changes
in the way the equipment operates. SEE problems with wiring and cables, hydraulic
connections, or other equipment. REPORT anything you see, feel, smell, or hear that is
different from what you expect, or that you think may be unsafe.
WEAR SAFETY EQUIPMENT
Wear a hard hat, safety shoes, safety glasses and other applicable personal protective
equipment. Remove jewelry and rings, do not wear loose-fitting clothing and tie back long
hair that could catch on controls or moving machinery.
FACER BLADES ARE SHARP & CAN CUT
Never attempt to remove shavings while the facer is running, or
is in the facing position between the jaws. Use care when operating the facer and when
handling the unit.
HEATER IS HOT & CAN BURN
The heater can burn skin and clothing. Keep the heater in its
insulated heater frame or stand when not in use and use care when heating the pipe.

PREPARE
PIPE
ENDS
2
• Close the carriage with the minimal force necessary to FACE the pipe ends.
• Continue facing until the jaws come into contact with both mechanical stops
and have produced a minimum of one complete ribbon.
• CLEAN fusion area after facing.
• At FACING force, check ALIGNMENT of the pipe ends and check for GAPS.
INSPECT,
CLEAN &
INSTALL
PIPE
1
• INSPECT machine and pipe.
• Review HEAT SOAK time, BEAD SIZE, OPEN/CLOSE time, and COOLING time.
• CLEAN inserts and pipe.
• Install and clamp pipe. If pipe ends are fairly even, check ALIGNMENT.

PREPARE
HEATER
• Review FUSING parameters.
• Ensure the pipe does not slip through the jaws at
FUSING force.
• Check the heater TEMPERATURE and CLEAN heater surfaces.
• Set the heater into the machine between the pipe ends.
3
• To close, SNAP the pipe ends sharply against the heater to ensure full contact.
• At this point, RELAX the force without breaking contact with the heater.
• Engage the LOCKING CAM. (Except when using a 2CU.)
• Maintain contact of pipe ends against the heater with NO FORCE during the
entire HEAT SOAK time.

• When appropriate bead size
is observed, open the carriage and REMOVE the heater.
• Leave the LOCKING CAM engaged during heater removal.
• INSPECT the pipe ends for condition of the melt.
FUSE &
COOL
6
• Close the carriage quickly
and smoothly with enough FUSING force to roll both melt beads over so that
they touch the piping component OD surfaces.
• Hold FUSING force for 10 SECONDS, then the LOCKING CAM will hold that jaw
position. (For the 2CU, hold FUSING force for the entire COOLING time.)
• Leave the LOCKING CAM engaged until COOLING time is complete.
