quality and safety are maintained.
Failure to comply with this provision will dispense
the manufacturer from any warranty and liability
claims for the product, including any consequential

When serviced, the unit is upgraded automatically to the
technical specifications of the product at the moment it is

We recommend having the product serviced at least every
twelve months.
Any provisions in the law pertaining to an electrical safety
inspection have to be complied with.

Principles of Operation
The HCU 300 allows welding electrofusion fittings that fea-
ture a bar code. Every fitting is provided with a tag with
one or two bar codes on it. The structure of this code is
internationally standardized. The first code, encoding the
data on proper welding, complies with ISO TR 13950, the
second code, if present, encoding the component trace-
ability data, complies with ISO 12176-4.
The welding control program supports certain of the ex-
tended traceability data encoded under the ISO 12176-4
standard, e.g., the fitting traceability code. To use this
feature, the desired data have to be enabled in the con-
figuration menu, at "Recording" (see Sect. 10.1).
The welding parameters can also be entered manually. The
