Part 3 Execution
3.1 Installation
A. Pipe and fittings shall be installed 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, mechanical joint process,
testing procedure, etc.). At the conclusion of the
installation seminar, all installers will be given a certification
test and, upon successful completion of said test, 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.
B. Only the GF Piping Systems LLC fusion units MSA-250 SE or “Electro Plus”
may be used in the installation of the Fuseal and Fuseal 25/50 piping
systems. Under this specification, the contractor shall be responsible
for purchasing either one MSA-250 SE or one “Electro Plus” fusion unit
for use in installation of the product on site. At the completion of the
installation and testing of the piping system, the contractor shall turn over
the fusion unit to facility personnel for their use in future system
upgrades, layout changes, etc.
C. Installer shall ensure that all pipe and fittings used for the
special waste piping system are components of the same
system. No mixing of various manufacturers pipe and or
fittings shall be allowed. Acceptable manufacturers are
GF Piping Systems LLC or approved equal.
3.2 Testing
A. The system shall be tested in accordance with all local
plumbing codes. All sections of the piping system shall be
tested with a maximum of 30 foot head of water (approx.
15 PSI ) for fusion system. Under no circumstances
should the system be tested with air or any other gas.
Joints may be pressure tested 10 minutes after fusion is
completed. (Mechanical joints shall be tested to a minimum
10 foot head or 5 PSI). Fuseal PP and PVDF pipe and fitting systems
may be installed for conveyance of pumped discharge up to 50 psi, consult
your local GF representative for more information.
