1 Cut both pipe ends with the pipe cutter (supplied with the tool set). Once the cutting blade has touched the pipe it must be cut (any non visible micro fractures could seriously reduce the burst strength of the pipe). Slide a compression sleeve onto each pipe end. The inner chamfer of the EVERLOC compression sleeve must be facing towards the cut end of the pipe.
2 Expand the pipe end with the correct sized expander heads (see expander head for size). Expand the pipe then rotate the expander heads by 20-25°. Repeat the expansion process to achieve a uniformed expanded bore head. IMPORTANT If the expander head is missing a segment (for example due to mechanical damage) then no further connection should be made with this head, as one-sided expansions will lead to leaks.
3 Push the expanded pipe ends onto each end of the fitting up to the pre set stop (last raised rib). Slide the compression sleeve to the collar of the fitting using the jointing tool (use the correct size jaws). When using RAUTOOL M1, make sure the release slider is in the top most position before the jointing tool is positioned over the fitting.
4 To release the manual RAUTOOL M1, slide the release slider down and to the side. To release the hydraulic RAUTOOL H1 simply press the black release button next to the pump.
5 If the pipework is to be covered by screed then the brass fittings must be protected by tape.
6 According to BS EN 1264, all underfloor heating joints must be clearly marked on the installation drawing.
