®
technology, a quick and easy way of identifying unpressed
connections during the pressure testing process. This indentation is removed during the pressing process,
creating a leak-free, permanent connection. Smart Connect technology provides identification of connections
which have not been pressed prior to putting the system in to operation. Smart Connect technology may be
pressure tested with air or water.
■ When testing with air, the pressure range is ½ psi to 45 psi maximum.
■ When testing with water, the pressure range is 15 psi to 85 psi maximum.
B. The Smart Connect technology pressure test is not a substitute for local code required pressure testing of the
piping system. Carry out the final piping system pressure test in accordance with local codes.
