Location:
The timers are located inside the left front of
the brewer on the upper part of the component bracket.
Test Procedures:
1. Disconnect the brewer from the power source.
2. Disconnect the wires from the timer terminals
TL3, TL4 and TL5 and rotate the dial(s) fully
counterclockwise.
3. Check the voltage across terminals TL1 and TL2
with a voltmeter when the "ON/OFF" switch is in the
"ON" position. Connect the brewer to the power
source. The indication must be:
a.) 120 volts ac for three wire 120/208 volt mod-
els and three wire 120/240 volt models.
b.) 200 to 240 volts ac for two wire 200 or 240 volt
models.
4. Disconnect the brewer from the power source.
If voltage is present as described for the right timer
reconnect the pink wire to TL3, white/green to TL4 and
white/yellow to TL5. For the left timer reconnect the

pink wire to TL3, white/brown to TL4, yellow to TL5
and proceed to #5.
If voltage is not present as described, refer to the
wiring diagrams and check the brewer wiring harness.
NOTE: ECA MODELS ONLY - Brewer must be at
operating temperature to perform step 5 or brew-lock
must be bypassed. To bypass brew-lock disconnect
white/orange and brown/black for right timer or or-
ange and red/black for left timer from brew-lock of
ECA and connect the harness leads together.
5. Place 1/2 gallon server under the funnel and select
1/2 gallon position on the selector switch.
6. Check the voltage across terminals TL1 and TL4
with a voltmeter when the "ON/OFF" switch is in the
"ON" position. Connect the brewer to the power
source and press the start switch. The indication
must be:
a.) 120 volts ac for three wire 120/208 volt mod-
els and three wire 120/208 volt models for
approximately 20 seconds for 1/2 gallon batch.
b.) 200 to 240 volts ac for two wire 200 or 240 volt
models for approximately 20 seconds for 1/2
gallon batch.
7. Place a 1-3/4 gallon server under the funnel. Select
a 1 gallon batch and repeat #6. The voltage indica-
tion should remain for approximately 40 seconds.
8. Select a 1-3/4 gallon batch and repeat #6. The
indication should remain approximately 1 minute.
9. Reconnect brew-lock wires if necessary.
Removal and Replacement:
1. Remove all wires from the timer.
2. Remove the four #6-32 slotted head screws hold-
ing circuit board and dial plate on to the compo-
nent mounting bracket.
3. Remove circuit board, nylon spacers and dial
plate.
4. Install new dial plate and circuit board with nylon
spacers to component mounting bracket.
5. Refer to the illustration on the following pages
when reconnecting wires.
6. Adjust timer dials as required.
