Fusion preparation
7.1
General information
The Fusion Process described in the following chapters is based on the instruction
sheets and guidelines issued by the DVS 2207.
The fusion area should be protected against the influences of weather (humidity,
ambient temperature <+ 5 °C, extreme direct exposure to sun) with such measures as
pre-warming the fusion materials, tents, heating.
For optimal use of the ECOS 160/250/315 the operating personnel should be specially
trained by Georg Fischer. In-depth knowledge of the machine and it´s components and
competence rule out handling errors thereby also preventing faulty fusion joints.

Preparations
The standard configuration of the base machine is prepared to joint pipe to pipe by
using 2 clamps to fix each pipe in the base machine. The planer and the heating
element is inserted between the two central clamps.
In order to clamp particular constructions or T-pieces or to use a flange adapter, shift
the clamping unit B to the required position. Therefore remove the two spacers C
(upper and lower on) from the original position, position the clamping unit B and fix it
with the two spacers C. The pipe preparation and welding position is now changed,
insert the heating element into the pull-off mechanism between A and B.
Clean the couplings on the base machine and the hoses.
Connect the hydraulic hoses to the base machine and to the hydraulic unit.
If the hydraulic hoses are not used, seal the couplings with the protective caps. Clean
the protective caps first.
Replace the heater if the PTFE -coating is damaged. Failure to comply could impair the
quality of the fusion weld.
In order to weld pipes and/or fittings with an outer diameter smaller than the clamp of
the base machine, insert matching clamping half shells and fasten them with the
screws.
