ENVIRONMENTAL HAZARD

damage.
Mercury is a hazardous waste. Federal regulations require that
Mercury be disposed of properly.
3. Open thermostat (mounting base) to expose mounting holes. The base
can be removed to simplify mounting. Press the thumb release at the top
of the thermostat and snap apart carefully to separate mounting base from
remainder of thermostat.
4. Route thermostat wires through large hole in mounting base. Level mounting
base against wall (for aesthetic value only—thermostat need not be level for
proper operation) and mark wall through 2 mounting holes. See Fig. 1.
