All VT7600
series
controls are
for use as
operating controls only and
are not safety devices. These
instruments have undergone
rigorous tests and verifications
prior to shipment to ensure
proper and reliable operation
in the field. Whenever a
control failure could lead to
personal injury and/or loss of
property, it becomes the
responsibility of the user /
installer / electrical system
designer to incorporate safety
devices ( such as relays,
flow switch, thermal
protections, etc…) and/or
alarm system to protect the
entire system against such
catastrophic failures.
Tampering of the devices or
miss application of the device
will void warranty.
