Recycling Thermostat
If this thermostat REPLACES a thermostat that contains mercury,
DO NOT discard the old thermostat in the regular trash. Mercury is harmful
to humans and the environment. For this reason, do not open, break, or
crush the mercury cell. If mercury leaks from a damaged cell, DO NOT
touch or handle mercury with bare hands. Use protective, non-absorbent
gloves to place mercury into a sealable container. Fill the container with
sand or another absorbent material and seal the container completely.
Return the mercury or mercury products, in a sealed container, to Invensys
Climate Controls or a local recycling center for proper disposal. If you have
any questions, call Robertshaw technical support at 1-800-445-8299.
