Introduction
IntroductionIntroduction
Introduction
UES hot glue systems meet your highest expectations in terms of quality, labour and production
reliability as well as maintenance and user friendliness.
By combining cutting-edge control technology with comfortable and complete features, you have the
greatest possible benefit. An extremely compact design and the modular extension option assure
variable use for versatile applications.
The UES tank system "perfectMelt" is equipped with carefully selected components of very high
quality. When adhering to these Operating Instructions, a long-term and unlimited use of the device
is possible.
Along with a full range of standard applications of adhesive technology with tank systems, hose and
gun systems, we also offer individual solutions and system components for special applications in
various industrial sectors.
With the adhesive application systems of the "perfectMelt" series, the process is conducted in the
context of the hotmelt adhesive application. In other words, depending on the application, the
adhesive systems are incorporated into production or packaging machines, and, as such,are part of
the equipment.
In the operation of adhesive application systems for hotmelt, the adhesive is processed at high
temperatures and with high-pressure material. For this reason, safety precautions are to be taken
during installation, operation and maintenance.
In the description of the operation of the system, these safety precautions are marked by safety
symbols and, if applicable, further information.
The safety precautions described here refer exclusively to the handling of the adhesive system.
Before commissioning, the Operating Instructions are to be read in full in order to ensure safety and
proper operation. The device owner or operator is responsible for compliance with the safety
regulations.
All operating instructions and manuals of the company UES are copyrighted. Copying, reproduction
(or part thereof), translation, etc. is not allowed without permission by UES AG. Additional copies of
these Operating Instructions can be acquired directly from the factory. Furthermore, the
manufacturer is not responsible for the accuracy of the contents of this manual.
These Operating Instructions are subject to changes.

Safety Instructions
Safety InstructionsSafety Instructions
Safety Instructions
The following Safety Instructions must be observed!
Caution:
Before any repair and adjustment work, unplug from the mains
Installation and maintenance work may only be performed by trained personnel.
Only those individuals shall be considered suitable who are qualified by specialised training and
experience in dealing with these or similar devices, who know the relevant safety and accident
prevention regulations, and who therefore can recognise and avoid hazards.
Work on the adhesive application system may generally only be conducted when the voltage has
been turned off and the compressed air has been blocked (depressurise the system).
The system must not be operated without the appropriate covers and safety panels. Be careful of
non-covered moving and rotating parts, such as motor and pump shafts, hub and swivelling
mechanisms!
Caution: Do not use the system for any purpose other than that for which it is intended
On many non-covered parts of the applicator device, the hot glue hoses and application guns consist
of high temperatures during operation. Hot and pressurised adhesive may cause severe skin burns.
Therefore, always wear protective clothing, gloves and safety goggles when working on the system,
such as when filling the melting tank or connecting and installing the hoses and valves. Some
adhesives produce toxic fumes that have to be extracted. The hot melt adhesive application
equipment may not be operated under the following circumstances:
- In the vicinity of volatile substances or explosive materials and gasses
- Without adequate protection
- At temperatures of less than 5 °C or more than 45 °C
Security measures with respect to the adhesive

Security measures with respect to the adhesive
When working with molten hot glue, always be extremely careful! These materials solidify very
quickly, even at high temperatures, so they can still be very hot even in their solid state and can
result in burns when in brought into contact with the skin. The safety precautions of the adhesive
manufacturer are to be observed. These can be found on the data sheet of the adhesive. Comply
with the processing temperatures recommended by the glue manufacturer!
When working with hot melt, wear gloves, safety glasses and long sleeves to prevent burns. In the
case of a burn, do not attempt to remove the glue from a person's skin; instead, hold the wounded
site under cold water until the glue has cooled and then contact a physician.

Safeguards with respect to the production machine
For the safety regulations in dealing with the production or packaging machine, please refer to the
documentation supplied with these devices.
For installation and maintenance work, the Safety Instructions for the parent machine in which the
adhesive application system is installed must be observed.

The fuel tank cap closes the tank. After filling, please use the fuel tank cap to close the tank of your
perfectMelt system.
The hot glue is melted in the tank. Your perfectMelt has two adjustable heating zones: the tank "t1"
and the manifold block "t2" (distribution block to connect the hot glue hoses).
The pump places the melted glue under pressure. UES-pumps have a translation ratio of 14:1. In
other words, at a set air pressure of 2 bar, there is a material pressure of 28 bar.
To prevent contamination in the hoses and application guns, the perfectMelt has a (tank) glue filter.
The hot glue hoses are connected to the glue dispenser. They are heated electrically and are
connected with the perfectMelt by a plug.
As an option, an in-line filter can be installed between the hose end and the gun.
The supply block is supplied with hot glue via the tube. It is also heated and is connected to the hose
electrically.

One or more modules are bolted onto the supply block. The modules open and close by air control
(via a solenoid valve).
For standard modules, screwable vents are necessary. Different nozzles are available for different
applications.

Warning
To prevent injury caused by falling, the tank system has to be firmly screwed
together with the production machine in any case.
The tank system is equipped with two mounting brackets. These angles have 9 mm holes to secure
the tank system with M8 bolts to the production machine. For this purpose, holes that are about 9
mm in diameter have to be drilled in the seat for the tank system of the production machine.
The tank system should be positioned so that an operator is not ergonomically impaired. This
particularly applies to settings on the control panel, filling the tank and maintenance work, such as
filter changes.
Warning
Please make sure that, when drilling holes, no cables, pipes or other equipment installations are
damaged

Make sure that there is an absolutely tight connection between the system, the hoses and the
guns via the screwed glue nipple. Otherwise, any escaping glue can lead to severe burns.
Pneumatic components are designed and constructed according to the applicable standards and
calculations such that, under the intended conditions of use, rupture or failure due to fatigue or
wear is not expected to occur.

Caution:
When refilling the glue, any spouting hot glue can cause injuries.
In any case, observe the safety regulations for handling melted adhesives.
•Do not leave the adhesive supply open; only store it in sealed containers.
•The fuel tank lid should be able to be opened without foreign bodies (such as scraps of paper)
being able to fall into it.
•Before filling, check to see whether the tank and the adhesive supply are clean and free of debris.
•Do not overfill your system. Add adhesive carefully to a max. 20 mm below the tank opening.
•Close the tank lid after filling. This prevents unwanted foreign matter from entering the tank or
hot adhesive vapours from escaping.
•The tank lid should be closed without it coming into direct contact with the adhesive.
•Do not run your device when it is completely empty. If there is too little adhesive in the tank,
localised overheating can result in
•glue burns and deposits in your system, leading to a malfunction.
•Refer to the data sheet of your adhesive supplier and set your device appropriately.
