T- 3.0.6 VERIFY TEMPERATURE
a) “No Water” OR Flow Error alarms turn the heater off! From here forward, if (and ONLY if) either occurs
address the alarm first!
b) Allow fifteen (15) FULL minutes OR until if the external meter reads 50° C or more. Based on the
external meter reading, TWO (2) possible scenarios below:
1) IF (and ONLY if) DOES NOT achieve 50° C or more: See procedure number T- 3.0.7
(page 303).
2) IF 50° C or more: Allow up to fifteen (15) minutes longer. TWO (2) possible scenarios i) or ii)
below:
i) IF (and ONLY if) the meter NEVER ACHIEVES 80° C OR does but then falls and
REMAINS less than 79° C for three (3) minutes: See procedure number T- 3.0.7
(page 303).
ii) IF the meter STAYS at 80° C or more: Proceed to
page 305, procedure number T- 3.0.9.
T- 3.0.7 NEVER 80° C / ISOLATE HEATER VOLTAGE
a) Figure right, unplug the connector from the 1
st
distribution board position from the left, “CON-NTC”.
This is temp control sensor’s NTC #2’s connector!
b) ENSURE the HEATER Switch is on.
c)
Set your volt meter to AC voltage
(~ V, V
AC
)!
d) Figure right, measure at the distribution board’s
Heater Connector BETWEEN the BLUE and
BROWN wires. TWO (2) possible scenarios:
1) IF (and ONLY if) less than 20 volts AC:
Leaving NTC #2 unplugged, proceed to
page
281, procedure number T- 2.0.0.
2) IF more than 100 volts AC: Leaving NTC #2 unplugged, perform parts a AND b below:
a)
CAUTION! To avoid damage DO NOT leave the machine. The external meter MUST NOT
be allowed to go higher than 95° C.
b) Watch the external meter for up to fifteen (15) minutes OR until if it achieves more than 80°
