105° C.
3. BLOWER MOTOR (BLWM) & INDUCER MOTOR (IDM) CONTAIN AUTO-RESET
THERMAL OVERLOAD SWITCH.
4. BLOWER MOTOR FACTORY SPEED SELECTIONS (PL4) ARE FOR AVERAGE
CONDITIONS. SEE INSTALLATION INSTRUCTIONS FOR DETAILS ON OPTIMUM
SPEED SELECTIONS.
5. USE ONLY COPPER WIRE BETWEEN THE DISCONNECT SWITCH AND THE
FURNACE JUNCTION BOX (JB).
6. SYMBOLS ARE ELECTRICAL REPRESENTATIONS ONLY.
7. AUXILIARY LIMIT SWITCH (ALS) USED ON DOWNFLOW MODELS ONLY.
8. THE TRANSFORMER 24VAC WINDING IS PROTECTED BY A 3 AMP AUTOMOTIVE
BLADE TYPE FUSE ON THE CONTROL BOARD. A 24VAC SHORT TO GROUND
DURING INSTALLATION, CHECKOUT, OPERATION, SERVICE OR MAINTENANCE
COULD CAUSE THIS FUSE TO OPEN. DO NOT REPLACE THE 3 AMP FUSE
WITH ANY OTHER SIZE FUSE.
