Introduction
Dear Customer:
Thank you very much for purchasing our product. We are confident that
it will meet your expectations.
The HST 300 Easy Welding Unit is designed exclusively for welding
electrofusion fittings made of plastic in the operating range of 20 through
315 mm that do not require more than 1000 s of welding duration. The
model version HST 300 Easy D additionally records data on the welding
process, including user inputs, and saves them to a welding report that
can be printed or downloaded to a PC for further processing.
The HST 300 Easy was manufactured and checked according to state-
of-the-art technology and widely recognized safety regulations and is
equipped with the appropriate safety features.
Before shipment, it was checked for operation reliability and safety. In
the event of errors of handling or misuse, however, the following may be
exposed to hazards:
•
the operator's health,
•
the HST 300 Easy and other hardware of the operator,
•
the efficient work of the HST 300 Easy.
All persons involved in the installation, operation, maintenance, and
service of the HST 300 Easy have to
•
be properly qualified,
•
operate the HST 300 Easy only when observed,
•
read carefully and conform to the User's Manual before working with
the welding unit.
Thank you.

Safety Messages
2.1
Using the Correct Cable Connector
Use the appropriate cable connectors that are compatible with the fitting
type used. Be sure the contact is firmly established and do not use burnt
cable connectors or connection adapters or such that are not designed
for the intended use.
2.2
Improper Use of the Welding and Power Supply Cables
Do not carry the HST 300 Easy by its cord and do not pull the cord to
unplug the unit from the socket. Protect the cables from heat, oil, and
cutting edges.
2.3
Securing the Fitting and the Joint
Use clamps or a vice to secure the fitting and the joint to be made before
welding. The fitting manufacturer's installation instructions, DVGW, DVS,
European and national regulations have to be respected in all cases.
The welding procedure must never be repeated on the same fitting, since
this may cause parts under power to be accessible to the touch.
