on its base. To do this hang the top of
the unit by the tabs on the base, then
snap the bottom of the unit into place.
Remove sticker from display.
These diagrams are provided for new installations
or unreferenced wires.
Do not use unnecessary force. If the body does not snap into place easily,
remove the body, re-hang it from the tabs and try again.
17. Turn the power back on to your heating and/or air conditioning system.
18. Verify that the system and its fan are operating properly. When set to a
high temperature, the heating system should provide warm air after a short
time. Likewise, a cooling system should provide cool air after a short time.
Usually sound from the furnace and air conditioning units can be heard
while they are running. The rush of moving air should be heard within a
short time after either has been started.
