2. Safety Messages
Improper Use of the Welding and Power Supply Cables
Do not carry the product by one of its cables and do not pull the power cord to unplug the unit from the
socket. Protect the cables against heat, oil, and cutting edges.
Securing the Fitting and the Joint
Use appropriate clamps to secure the fitting and the joint before welding. The welding unit is intended
exclusively for indoor installation applications. Use for buried pipeline construction applications is
prohibited.
Cleaning the Welding Unit
The product must not be sprayed with or immersed in water.
Opening the Unit
Caution: The cover of the product may be removed only by Acu-Tech Piping Systems personnel, or of a
partner organization properly trained and approved by the manufacturer.
Checking for Damage
Every time before operating the product, carefully check safety features or possibly existing parts with
minor damage for intended and proper function. Make sure that the push-on connection terminals work
properly, that contact is fully established, and that the contact surfaces are clean. All parts have to be
installed correctly and properly conform to all conditions in order for the operator to be sure that the
product works as intended. Damaged safety features or functional parts should be properly repaired or
replaced by a qualified organization/service shop.
Mains Power Supply
Utility suppliers’ wiring requirements, VDE provisions, occupational safety rules, DIN / CEN regulations, and
national codes must be respected.
Mains power fuse protection should be max. 10 A.
The product must be protected against rain and humidity.
3. Operation
The Acu-Tech EF300 welding unit allows using electrofusion fittings to join pressure pipes and fittings, of
the makes Geberit, Akatherm-Euro, Coes, Valsir, Waviduo, and Vulcathene-Euro.
The microprocessor-controlled unit;
-Controls and monitors the welding process in a fully automated fashion,
-Determines welding duration depending on ambient temperature,
-Indicates all information with three LEDs and a seven-segment display screen.
1. Turning the Welding Unit On
After connecting the power supply cord to 230 V mains power, turn the welding unit on at the On/Off
switch. The unit then performs an auto-test. All three LEDs light up briefly and simultaneously to indicate
that the unit is ready for operation. Furthermore, the seven-segment characters show the welding mode
“H00”for approximately 1 second. After this, both the LEDs and the screen characters go off again.

2. Connecting the Electrofusion Fitting
Connect the connection terminals to the fitting and check for proper fit. The contact surfaces of the
connection terminals and the fitting have to be clean. Dirty terminals may lead to improper welding and
also to overheated and fused terminal plugs.
After the fitting was connected, the yellow LED (Fitting connected) lights up. At the same time, the screen
displays the welding time. The welding process can now be started by pressing the START key.
The welding time is counted down from about 80 seconds.
3. Welding Process
The welding process is monitored for its entire duration, applying the welding parameters computed for
the electrofusion fitting.
4. End of Welding
The welding process was completed successfully if the actual welding time is 0 s (“000”on the display
screen), the green LED (End) lights up at that point, and the audible signal beeps twice.
5. Aborted Welding
The welding process has caused errors if the red LED (Fault) is on and the audible signal beeps
intermittently. Additionally, an error code is displayed on the screen. See section 4 for more detail.
An error has to be acknowledged by pressing the STOP key.
6. Cooling Time
The cooling time as given in the fitting manufacturer’s instructions has to be respected. Note that for that
time the pipe/fitting joint which is still warm must not be subjected to an external force.
7. Returning to the Start of Welding
After welding is finished, disconnecting the welded fitting from the welding unit will cause the unit to
return to the start of welding. An additional safety feature prevents a given electrofusion fitting from being
welded twice inadvertently: after a properly completed or an aborted welding operation, the welding unit
has to be disconnected from the fitting first, in order to be ready for the next welding.
4. Error Messages - Self-Monitoring Functions Overview
1. Power Supply Failure (E01)
The last welding is incomplete. The welding unit was disconnected from the power supply. This error has to
be acknowledged by pressing the STOP key.
2. No Contact (E02)
There is no properly established electrical contact between the welding unit and the fitting (check push-on
terminal on fitting), or the heater coil is defective.
3. Low Voltage (E03)
The input voltage is below 180 volts. Adjust generator output voltage.

EF300 Electrofusion Welder Manual Version 1.1 Page 4of 5
4. Overvoltage (E0)
The input voltage is above 280 volts. Adjust generator output voltage.
5. Temperature Error or Temperature Sensor Defective (E05)
The measured ambient temperature is outside the operating range of the welding unit, i.e., below –5°C or
over + 40°C.
If this error is displayed during the unit’s auto-test, the temperature sensor is defective.
6. Frequency Error (E06)
The frequency of the input voltage is out of tolerance (40 Hz - 70 Hz).
7. Low or Excess Current (E07)
The message is displayed if the there is a momentary current failure or if the current regulator is defective.
8. Emergency Off (E08)
The welding process was interrupted by pressing the STOP key.
9. Used Fitting Error (E09)
After welding, the unit was not disconnected from the electrofusion fitting, and the user tried to weld the
same fitting a second time.
10. System Error (E00)
Caution: The welding unit must be disconnected immediately from the power supply and the fitting. The
auto-test has found an error in the system. The unit must no longer be operated and has to be turned in
for check and repair.
