1-1
1. SAFETY GUIDELINES
General
The information contained in this section applies not only to everyday
equipment operation, but also to any procedure carried out on it, whether for
preventive maintenance or in the case of repairs and the replacement of worn
out parts.
It is very important to observe the safety warnings in this manual at all times.
Failure to do so may result in personal injury and/or damage to the equipment
or the rest of the installation.
Before beginning work on the equipment, read this manual carefully, and in
case of any doubt, contact our Technical Service Center. We are available for
any clarification that you might need.
Keep manuals in perfect condition and within reach of personnel that use the
equipment and perform maintenance on it.
Also provide necessary safety material: appropriate clothing, footwear, gloves
and safety glasses.
In all cases, observe local regulations regarding risk prevention and safety.
Symbols
The symbols used on both the melter/applicator equipment and in this manual
always represent the type of risk we are exposed to. Failure to abide by a
warning signal may result in personal injury and/or damage to the equipment
or the rest of the installation.
Warning: Risk of electrical shock. Carelessness may produce injury or death.
Warning: Hot zone with high temperatures. Risk of burns. Use thermal
protective equipment.
Warning: System under pressure. Risk of burns or particle projection. Use
thermal protective equipment and glasses.
Warning: Important information for the correct use of the system. May include
one or several of the previous hazards, and therefore must be kept in mind to
avoid damage and injury.
Warning: Dangerous area. Risk of entrapment. Carelessness may produce
injury or death.

SAFETY GUIDELINES
Mechanical components
The hot-melt installation, which is installed to this device, requires moving
parts that can cause damage. Use the equipment correctly, and do not remove
the safety guards while the equipment is in operation; prevent the risk of
possible entrapment due to moving mechanical parts.
Do not use the equipment if the safety devices are not in place or appear to be
inadequately installed.
For maintenance or repair operations, stop the movement of moveable parts
by turning off the main switch.
The device has no moving mechanical parts, so it does not pose risks to
consider in this section.
Electrical components
The system works with single-phase or three-phase current of a certain
power. Never handle the equipment with the power connected, as this may
result in powerful electrical shocks.
The installation must be correctly grounded.
The installation’s power cable conductors must match the required electric
current and voltage.
Periodically inspect the cables to check for crushing, wear and tear, as well as
to prevent tripping and falls as a result of their placement.
Although the system meets EMC requirements, it is inadvisable to use
devices that transmit high levels of radiation, i.e., mobile phones or soldering
equipment in their vecinity.
Hydraulic components
As this is a pressurized system, precautions related to this type of equipment
must be observed.
Before each operation, always make sure that the adhesive circuit is
completely free of pressure. There is a high risk of hot particle projection,
along with the corresponding danger of burns.
Use caution with the residual pressure that may remain in the hoses when the
adhesive cools. When reheated, there is a risk of hot particle projection if the
outputs are left open.
Pneumatic components
Some equipment uses compressed air to 6 bar pressure. Before any
manipulation, please ensure that the circuit has lost fully air pressure. The
risk of projection of particles at high speed can cause injury to a certain
severity.
Extreme precautions with the residual pressure that could be contained in the
circuit, before disconnecting any pneumatic feeding tube.

MA-5160-ENG MICRON+TPD ADHESIVE MELTERSAFETY GUIDELINES
1-3
Thermal components
The entire system works with temperatures that can exceed 200°C (392°F).
The equipment must be operated using adequate protection (clothing,
footwear, gloves and protective glasses) that completely cover exposed parts
of the body.
Keep in mind that, due to the high temperatures reached, the heat does not
dissipate immediately, even when the power (in this case, electric) source is
disconnected. Therefore, use caution, even with the adhesive itself. It may
remain very hot, even in a solid state.
In case of burns:
1. If the burn is the result of contact with melted adhesive, do not try to
remove the adhesive material from the skin. Do not try to remove it once
it has solidified either.
2. Cool the affected area down immediately with lots of cold and clean water.
3. Seek medical attention as soon as possible either from the company’s
medical service or the nearest hospital. Provide the medical staff with the
Safety Information Sheet of the adhesive.
Materials
Meler systems are designed for use with hot-melt adhesives. They should
not be used with any other type of material, and especially not with solvents,
which may cause personal injury or damage to internal system components.
Some units are specifically designed to use polyurethane reactive (PUR) hot-
melt adhesives. Using PUR on a unit that is not prepared for that purpose may
cause severe damage to the unit.
When using adhesive, follow the corresponding guidelines found in the
Technical and Safety Sheets provided by the manufacturer. Pay special
attention to the advised work temperatures in order to prevent adhesive
burning and degradation.
Ventilate the work area adequately in order to remove the vapors produced.
Avoid the prolonged inhalation of these vapors.
Always use original Meler components and replacement parts, which
guarantee the correct system operation and service.
Noise emission declaration
The A-weighted emission sound pressure level (LpA) of the unit in operation
does not exceed 70 dB(A) under any circumstances.
The maximum C-weighted sound pressure level (LpCpeak) and the A-weighted
sound power level (LWA) do not exceed values worthy of mention and thus do
not represent a specific risk that must be taken into account.

INTRODUCTION
Description
The ‘MICRON+’ are designed for use with ‘meler’ hoses and applicators in hot-
melt adhesive applications. Their different variations – line, coating or swirl-
spray – cover a wide range of applications, being very versatile in all markets
where they are used.
Modes of operation
The unit has the following operating modes:
• READY Mode (Prepared). The melter keeps the components hot at the
programmed working temperature. The pump is kept idle, awaiting an
adhesive pump request.
• RUNNING Mode (in Operation). The unit pumps adhesive, and all
programmed working conditions are correct.
• STOPPED Mode (Pumping disabled). The pump is kept disabled until the
pump is either manually or automatically activated.
• Heating Mode. The unit heats the areas up to the programmed
temperature. The pump is kept disabled.
• STANDBY Mode (Low consumption). The melter remains in standby while
maintaining all active areas at a programmable temperature. The pump
remains disabled.
• WARNING Mode. The melter detects an incorrect operation or warns the
operator about the event. The unit can continue to operate.
• ALARM Mode. The melter detects an operation error or warns the
operator about the event. Depending on the type of alarm, the unit may
continue to operate for a programmed amount of time.
• ERROR Mode. The melter detects an operation error or warns the
operator about the event. The unit cannot continue to operate, and
pumping is stopped immediately. Depending on the type of error, the unit
disconnects heating from all the areas.
• OFF Mode. The unit remains off with no areas heated and the pump
disabled. The power and pneumatic supply from the network to the unit is
maintained.
