1/2”
1" tool only
▶ For the 1" tool, open the tool handles fully (thumb grip is available to
maintain open jaw). Then close tool jaws to engage ratchet (ensure
that thumb grip is returned fully forward before closing jaws). For
other tools, go to the next step.
▶ Position the PureFlow press tool perpendicular over the press sleeve,
resting it against the tool locater ring. For 1" tool, close tool jaws to
engage ratchet (ensure that thumb grip is returned fully forward before
closing jaws). Make sure the PureFlow press tool is properly aligned.
The tool locater ring must be in the factory-installed position
while making a press to ensure a consistent leak-proof
connection. It may be necessary to rotate the tool locater
ring to avoid interference between the ring and tool.
▶ Close handles, using trigger to reduce grip span if desired.
▶ If the PureFlow press tool is not properly aligned with the locater
ring, use the emergency release (using a screw driver to turn the
emergency release) to open the press tool. Once released, align the
PureFlow press tool properly and go back to the previous step.
WARNING!
The connection is not leak-proof when the tool has been
opened by emergency release. The tool locater ring must
be present to ensure a proper PureFlow Press connection.
