Installation Instructions

1. Check Contents. Each product package includes a fitting and a

number of stiffeners to be used on each end of pipe being connected

(i.e. 2 stiffeners for a Coupler or Elbow, 3 for a Tee).

2. Cut the pipe square. There is no need to chamfer the pipe end.

Ensure any burrs on the pipe are removed and the pipe is clean.

3. Insert stiffeners. Insert the supplied stiffeners into each end of the

pipe being connected

4. Push stiffener into pipe. Push the stiffener all the way into the pipe

until the ridge is plush with the pipe end. This can be done by hand, or

gently tapped in with a mallet if required.

5. Ensure 3 threads are showing on the fitting body. The fitting is

supplied in a ready-to-use position. You do not need to disassemble

the fitting prior to use. Always ensure 3 threads are exposed on the

central body of the fitting prior to use.

6. Mark fitting depth. To ensure correct insertion depth and achieve a

successful sealing performance, witness mark the pipe against the

flange on the central body of the fitting. Line up the pipe against the

fitting and use the flange on the central body as the guide point to

witness mark against.

7. Insert the pipe into the fitting. Gently slide the pipe into the fitting so

the end of the nut reaches the witness mark on the pipe. No force is

required to do this. Do not insert beyond this point.

8. Tighten the fitting. Tighten the nut until the nut touches the flange

on the central body of the fitting. Do not tighten further once the nut

touches the flange as overtightening can damage the fitting. It is

recommended a wrench is used to tighten the nut.

9. Fitting is installed. The fitting is now full installed and ready for use.

Note nut position relative to the flange on the central body.

Check for system leaks prior to backfilling.

WARNING! Improper installation or operation of the system may result in fire, explosion, or asphyxiation.
