Important Notice
All VTR73xxA 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.
