Dimensions:
All R842 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 panel 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.
