TEMPERATURE CONTROL LEVER
1. Move the temperature control lever from its extreme left
position to its extreme right position and check to be sure
that it moves correctly and smoothly to each position.
2. Then move the temperature control lever to the extreme
left position, and check to be sure that warm air does not
come out when the blower is operated.
3. If the air flow is not correct in the above step, adjust the
temperature control wire.
