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.
