1) IF (and ONLY if) [Temperature] NEVER reaches at least 50° C: See procedure number
T- 3.0.1 (page 283).
2) IF [Temperature] INCREASES to 50° C or more: Continue to watch for up to twenty (20) FULL

T- 3.0.1 ISOLATE HEATER VOLTAGE
a) Figure right, unplug the connector from the
1st

heater on!
b)
Set your CALIBRATED volt meter to AC
voltage (~ V, V
AC
)!
c) Figure right, measure at the distribution board’s Heater
Connector, between the Heater Connector’s BROWN and
BLUE wires.
d) TWO (2) possible scenarios:
1) IF (and ONLY if) LESS THAN 100.0 volts AC!
Leaving NTC #2 unplugged, proceed to
