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 hot melt adhesive application. In other words, depending on the application, the adhesive systems
are incorporated into production or packaging machines, and, as such, part of the equipment.
In the operation of adhesive application systems for hot melt, 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
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 anything else than what it was manufactured for!
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
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.

Safety symbols
The safety symbols below highlight activities in this manual where increased caution is necessary. The
proposed safety precautions should be observed in any case.
Attention, general safety instructions:
Regards to safety instructions when working with glues and other machines. Additional (special)
safety instructions can follow.
Caution hot surface:
Danger of burning. Appliance parts have a high operating temperature.
Caution high voltage:
This type of work is only to be carried out by qualified personnel.
Caution hand injury:
Risk of entrapment if incautiously operated.
Caution, possible danger of uncontrolled release/leakage of hot liquids!
Wear safety gloves! Use safety glasses!
Disconnect power supplier! Use face shield!
Disconnect power plug before opening! Wear protective clothing!

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.

Installation
Checking the components
After unpacking, please check all the components of your perfectMelt and (if applicable) the hot glue
hoses and application heads for any damage.
If you notice any damage, please contact UES AG immediately.

Assembly and mounting of the tank system
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!
