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.
