CAUTION: All work must be performed by qualified personnel trained in the
proper application, installation, and maintenance of systems in accordance
with all applicable codes and ordinances.
CAUTION: If the valve repair kit is not installed, commissioned and
maintained properly, according to the instructions contained in this
manual, it may not operate correctly and may endanger the user.
CAUTION: Make sure that all the connecting pipework is water tight.
CAUTION: When making the water connections, make sure that the
pipework connecting the valve repair kit is not mechanically over-
stressed. Over time this could cause breakages, with consequent water
losses which, in turn, could cause harm to property and/or people.
CAUTION: Water temperatures higher than 100 °F (40 °C) can be dangerous.
During the installation, commissioning and maintenance of the valve repair kit,
take the necessary precautions to ensure that such temperatures do not
endanger people.
CAUTION: To prevent any damage which will cause the valve repair kit to not
operate correctly, treat highly aggressive water before entering the zone valve.
WARNING: The outer surface of the device, especially in polymer type
components, must not come into contact with any chemical substance, either
on purpose or accidentally. The system fluid and any chemical additives used
within the water piping system – whether for washing or as protection – must
be compatible with the materials used to make the device and with the function
it performs.
