* REFILL
Range: 0 to 155
This function allows the operator to adjust the sensitiv-
ity of the refill circuit. This is mainly a troubleshooting
feature. Water in different geographical locations can
have different conductivities. By adjusting the sensitivity
of the refill circuit, this will allow the brewer to operate
under various water conditions.
Procedure to set the sensitivity threshold of the refill
circuit:
NOTE: Make sure the water in the tank is touching the
refill probe.
1. Press and hold the right hidden switch until the
display reads SET LANGUAGE. Press and release the
right hidden switch until the display reads REFILL
and shows a number on both sides of the word.
2. To adjust the threshold setting, press (-) to decrease
or (+) to increase the setting.
NOTE: Always make sure that the number on the right
is larger than the number on the left when water is in
contact with the refill probe in the tank.
3. When finished, select DONE. This saves the new
setting and advances to the next function screen
(L) SPRAY OZ/M. To exit programming and return
to the MAIN SCREEN, press ENABLE BREW ON/
OFF switch.
* SPRAY OZ/M
This function allows the operator to view or enter the
actual flow rate coming out of each sprayhead. This is
NOT used to control the actual flow rate, but to tell the
internal processor how fast the water is flowing.
Procedure to set the sprayhead flow rate:
1. Press and hold the right hidden switch until the
display reads SET LANGUAGE. Press and release
the right hidden switch until the display reads SPRY
OZ/M. The number represents what the brewer
thinks is the flow rate out of that sprayhead.
2. If the actual flow rate of the sprayhead is known
but is different than the number on the display, use
the (-) and (+) to enter the correct flow rate.
3. Select DONE.
4. Repeat procedure for right side of Twins.
5. When finished, press and release DONE to advance
to the next screen. To exit programming and return
to the MAIN SCREEN, press ENABLE BREW ON/
OFF switch.
NOTE: If the flow rate is unknown, proceed to the
CALIBRATE FLOW screen.
* BYPASS OZ/M (ICB & ICB Twins only)
This function allows the operator to view or enter the
actual flow rate coming out of each bypass fitting. This
is NOT used to control the actual flow rate, but to tell
the internal processor how fast the water is flowing.
Procedure to adjust the bypass flow rate setting:
1. Press and hold the right hidden switch until the
display reads SET LANGUAGE. Press and release
the right hidden switch until the display reads
BYPASS OZ/M. The number represents what the
brewer thinks is the flow rate out of that bypass.
2. If the actual flow rate of the bypass is known but
is different than the number on the display, use the
(-) and (+) to enter the correct flow rate.
3. Select DONE.
4. Repeat procedure for right side of Twins.
5. When finished, press and release DONE to advance
to the next screen. To exit programming and return
to the MAIN SCREEN, press ENABLE BREW ON/
OFF switch.
NOTE: If the flow rate is unknown, proceed to the
CALIBRATE FLOW screen.
* DILUTE OZ/M (ITB/ITCB only)
This function allows the operator to view or to enter the
actual flow rate coming out of the dilution nozzle. This
is NOT used to control the actual flow rate, but to tell
the internal processor how fast the water is flowing.
Procedure to adjust the dilution flow rate setting:
1. Press and hold the right hidden switch until the
display reads SET LANGUAGE. Press and release the
right hidden switch until the display reads DILUTE
OZ/M. The number represents what the brewer
thinks is the flow rate out of the dilution nozzle.
