RECYCLING NOTICE
If this control is replacing a control that contains
mercury in a sealed tube, do
not
place your old
control in the trash.
Contact your local waste management authority for
instructions regarding recycling and the proper
disposal of any control containing mercury in a
sealed tube.
INSTALLATION
WARNING
HIGH VOLTAGE CONTROL.
ELECTRICAL SHOCK HAZARD.
This thermostat is a line voltage (120 to 277 volt)
control. Do not install this thermostat if you are not
completely familiar and competent with electrical
wiring. If improperly handled, there can be risk of 120
to 277 volt electric shock hazard that can cause
serious injury or death.
Location
Install a vertical outlet box that is used to mount the T498, four
to five feet (1.5m) above the floor on an inside wall where the
thermostat will be subjected to average room temperature.
Mount the thermostat away from concealed warm or cold water
pipes, warm air ducts, light switches and dimmers, refrigerators
or drafts from hallways, fireplaces, stairways or fans.
Mounting and Wiring
When replacing an old line voltage electric heating
thermostat, remove the old thermostat carefully to avoid
damaging the insulation on the wiring.
Check the old insulation for cracks, nicks, or fraying and apply
approved electrical tape where necessary to achieve adequate
insulation, or replace the wires using approved methods.

Fig. 2. Typical hookup for T498A Thermostat.
Leave the cover on the thermostat while making
connections.
Push the leadwires into the outlet box and insert the
thermostat into the box for mounting by pushing against
the cover.
Remove the thermostat cover by grasping the top and
bottom edges and pulling outward.
Turn the dial so that the setpoint indicator is at the
12 o’clock position. This will prevent accidental damage
to the dial stop during mounting.
Using a screwdriver, secure the thermostat to the outlet
box by tightening the two mounting screws. Handle the
thermostat with care; excessive pressure can damage
the control knob or sensing element.
CAUTION
1. Disconnect power supply before making wiring
connections to prevent electrical shock or
equipment damage.
2. All wiring must comply with applicable codes and
ordinances.
3 Thermostats are designed to be used with a
separate limit control in the appliance.
Using wire connectors
approved for No. 12 wires,
make
line voltage wiring connections directly to the leadwires
installed on the thermostat.
CAUTION
If connecting with aluminum conductors, use approved
CO/ALR solderless wire connectors to avoid fire
hazard.
