PROGRAMMING - PROCEDURES (continued)
Adjust Inlet Valve Time
Determining Pressure
and Flow
NOTE: The following procedure
must be performed by a
qualified technician!
This adjustment will
help
maintain consistent volume in
situations where water pressure
and flow is exceptionally high or
low
. This technique also helps
in determining the actual
pressure and flow.
IMPORTANT: DO NOT adjust
the inlet valve time if water
pressure at this location
fluctuates high to low.
1. Remove the top cover of the brewer. Identify and locate the
vent, or overflow tube.
2. Access the programming mode, go to Factory Settings and
then to “InletValvTime:” setting. Set to 25 seconds, press 3rd
key to register change in memory, then 2nd key to exit
programming mode.
3. Turn brewer on.
4. Place empty decanter (or airpot/thermal server) under the
brew basket.
5. Place empty decanter or other vessel under the faucet and
begin drawing water from the faucet.
6. When the inlet valve comes on, stop drawing water from the
faucet, and count the number of seconds before the water
reaches the vent or overflow tube. (The tubing is clear
enough that water will be visible when it starts to go into the
vent tube – count the number of seconds to when water is
first visible at the tube, not when the tube has filled.) Note
the number of seconds the valve was on until water becomes
visible at the vent tube.
7. The Inlet Valve Time should be 1/3 to ½ of the number of
seconds in #6 above. As an example, if it took 12 seconds
before water was visible at the vent tube, then the Inlet Valve
Time should be set between 4 and 6 seconds.
8. Repeat the above if necessary to confirm initial findings.
9. Turn brewer off, enter programming, then factory settings,
and set “InletValvTime” to proper time. Press 3rd key to
register change in memory, then 2nd key to exit programming
mode.
