box and lift away.
Disconnect wires from old thermostat. As you
disconnect each wire, tape the end and label it with
the letter of the terminal designation to make reconnection

Check the old insulation for cracks, nicks or fraying,
and apply high quality plastic tape where necessary
for adequate insulation.
Retain the old thermostat for reference purposes
