PROHIBITIVE ACTION: Red circled outline and slash over graphic.
This is an example of a symbol that calls attention to an action that is prohibited.
4. WORKING AREA
This equipment is normally run as a station within a conveyorized line. The operator will interact with
the PC terminal to change recipes or to monitor oven status. Access to the doors on the four corners
may be required for activities such as starting the PC, filling the lubrication tank, or adjusting the
pneumatic flow.
Additional maintenance beyond these actions, whether preventative or unplanned must be performed
by a qualified technician. Review the hazards section below to understand the hazardous areas on
the machine and how to avoid or isolate the energy which they contain.
Users working on the machine may need to use Personal Protective Equipment such as gloves,
respirators, or goggles.
5. HAZARDS
The Vitronics Soltec XPM
2
Reflow Soldering System is a piece of industrial equipment which could
present a variety of hazards to which workers may be exposed to under certain conditions.
HIGH VOLTAGE WARNING: High voltages are present in this area and can
cause personal injury. See the machine serial number plaque for the designated
supply voltage for each specific oven.
• To avoid exposure to high voltages ensure that all protective panels remain
closed during operation.
• Only qualified electricians should work on the electrical circuits of the
machine.
• Before working on an electrical circuit, turn main power off use appropriate
energy isolation and lock out procedures when servicing the machine.
• Ensure that the system is properly grounded.
HOT SURFACES: There is always a risk of being burned when you work around
the machine. Hot surfaces on the oven can cause burns.
• Always wear heat resistant gloves and protective clothing when working on
the machine.
• Never handle the finished boards without wearing protective gloves.
• If possible allow the machine time to cool down before you start servicing.
Most of the components in the soldering system don’t look hot. Always
assume that all parts are hot.

MECHANICAL HAZARDS: All moving parts including motors, pulleys, belts,
chains, sprockets, cooling fans, and cylinders present a potential danger.
• Be mindful of hair, clothing, jewelry and other body parts that can get caught
in a moving mechanism.
• Stop all moving parts and use appropriate energy isolation and lock-out
procedures when servicing the machine.
ALWAYS REPLACE/CLOSE COVERS WHEN SERVICE WORK IS
COMPLETED BEFORE OPERATING
FLUX VAPOR: The solder paste used on the printed circuit boards may consists
of tin, lead, flux, and other potentially hazardous materials. Repeatedly inhaling
the vapors produced in the reflow process may cause health problems in the long
term. This vapor must be exhausted from the area that the workers are operating.
• Maintain updated Material Safety Data Sheets for all products used in the
oven and ensure employees in contact with equipment are familiar with their
location and usage.
• Be sure that the exhaust system is working properly.
• Only run approved product and tested process though the oven.
• Never eat, drink or smoke while working on the machine.
• Wash hands after handling product.
FIRE HAZARD The solder paste used on the printed circuit board contains,
when heated, a noxious vapor that is inflammable. No smoking or open fire near
the machine
• No smoking or open fire near the machine
• Ensure the exhaust system to extract vapors and remove excess heat is
operating properly
• Do not place tools, papers, or other materials on top of the machine
• Be sure to locate a fire extinguisher in the vicinity of the machine
EYE HAZARD: When operation or servicing the machine, always protect your
eyes with safety glasses.

NITROGEN HAZARD: [if equipped] Follow the safety precautions and
procedures described in the Material Safety Data Sheet from the nitrogen
supplier. Nitrogen must be exhausted from the process area. If it is released in
within a confined space an oxygen deficiency will occur.
