System components shall be installed using the [Socket, IR® (Infrared) Butt Fusion or Standard Butt Fusion] joining method according to current installation instructions as delivered in print or documented online at www.gfpiping.com. An on-site installation seminar shall be conducted by GF personnel who are certified to conduct said seminar. Seminar topics shall include all aspects of product installation (storage, set up, support spacing, fusion process, machine care, testing procedure, etc.). At the conclusion of the seminar, all installers will be given a written certification test and will be required to prepare and complete one fusion joint of the type being implemented on the project. Upon successful completion of said test, the installer will be issued a certification card verifying that they have met the requirements of the manufacturer with regards to knowledge of proper product installation and testing methods.

  2. Only the following GF Piping Systems fusion units may be used to install the SYGEF® Standard piping system:

    For Socket Fusion Installation – SG 125 Socket Fusion Machine or MSE hand tool

    For IR Fusion Installation – IR-63 Plus®, IR-110 Plus®, IR-225 Plus®, IR-315 Plus® Infrared Butt Fusion Machines

    For BCF® Fusion Installations – BCF® Plus

  3. Under this specification, the contractor shall be responsible for the purchase or rental of the proper machine required to meet the intent of the specification and be used for installation of the product on site.

  4. Installer shall ensure that all pipe and fittings used for Pure Water Piping are components of the same system. No mixing of various manufacturers’ pipe and/or fittings shall be allowed.

3.3 TESTING

  1. The system shall be tested in accordance with the manufacturers’ recommendations. Please refer to Georg Fischer’s technical handbook for “Pressure Testing” guidelines.
