w 1 R <br />f <br />Joining primary piping Do not use the adhesive beyond its pot life. The pot life (working time) of mixed <br />adhesive is dependent on temperature and is reduced as the temperature increases. <br />When the pot life expires, the can may begin to feel warm and the adhesive will be <br />gummy or sticky when applied to the pipe. See POT LIFE/CURE TIME table below. <br />Applya thin, even coat ofmixedadhesive to <br />the inside of the be// and to the tapered <br />spigot ends (indicated by shading), <br />completely wetting all machined surfaces <br />with the adhesive. Wipe off excess adhesive <br />with the spatula provided in the kit. <br />Bring the bell and spigot together in a straight, even line. Insert the spigot until contact <br />of the matching taper in the bell occurs. When assembling 2 through 6 -inch pipe, rotate <br />the spigot end approximately 900 to redistribute the adhesive and work out any <br />trapped air whenever possible. Since tapers are matching, you should feel the joint <br />"lock" when a proper interference fit is obtained. If the joint will not lock, it is usually due <br />to excess adhesive, adhesive which is stiff because of cold weather, or adhesive <br />whose pot life has expired. When the joint has locked, hold the pipe and fitting together <br />for a few seconds to insure lock-up. Do not use any type of hammer or mallet to <br />makeup the joint. <br />Do not disturb the lock of the mated joint when installing additional lengths. <br />Do not move the joined piping until the adhesive has cured. <br />Note: For 8 -inch and larger nominal pipe sizes, refer to the Ameron installation manual <br />or consult Ameron. <br />Cutting the pipe Use a hacksaw with fine blade, a chopsaw, a reciprocating saw or an abrasive cutoff <br />wheel when cutting the pipe. Mark pipe with a wrap-around or heating blanket to insure <br />an even cut. If pipe is delivered with a factory -joined coupling, cut off the spigot end, <br />not the coupling. If necessary, pipe may be joined to a sleeve coupling to form a new <br />female bell end. <br />Taper the cut end of the pipe using the Ameron Taper -Tool (U.S. Pat. No. 3,540,328), <br />Taper -Tool ll, Taper -Maker or Unique Tapering Tool or a `pencil -sharpener' type tool <br />available from third parties or Ameron distributors. See instructions packed with tool <br />for details. <br />C <br />
