1. Identify the desired location for the Flex
Restraints.
2. Pipe must be clean. Remove all sources of
contamination using a lint free cloth and a
minimum of 90% or greater Isopropyl Alcohol.
3. Scribe witness marks onto the pipe surface,
or alternately, mark the area to be scraped/
peeled in a criss-cross pattern.
4. Scrape/Peel the pipe to remove the surface
layer and expose clean virgin pipe material
beneath. If witness marks remain, scrape the
pipe again.
5. The Flex Restraints must be secured to the
scraped area of the pipe surface. This can be
accomplished in a variety of ways (i.e. wormgear clamps, c-clamps or nylon ratchet
straps), ratchet straps are the recommended application tool due to the ease of use. Flex
Restraints must be evenly spaced around the circumference of the pipe. Mark the pipe and
restraint to ensure no movement of the fi ttings. Tape can be used to secure the fi tting until
the strap can be tightened.
6. Tighten the strap until the restraints are conformed to the pipe wall. Make sure the
restraints make contact with the pipe over the entire fusion area. If more than one restraint
is to be used, make sure that all fi ttings are in place before fully tightening the ratchet strap.
7. Connect the control box leads to the fi tting. The Flex Restraint is a temperature compensated
fi tting. If the data is entered in manual mode, make sure to set the fusion time as stated on the
barcode tag with the fi tting. If the data is entered by barcode mode, the fusion parameters
should be automatically set.
8. After the fusion cycle is complete, the restraints and clamping device being used must remain
in place and be allowed to cool for 15 minutes. The Flex Restraints should be completely cool
before it is subjected to any forces.
