INSTALLATION INSTRUCTIONS (CONT’D)
2) For Automatic Models: Adjust the “Brew” dial on timer to deliver desired amount of water. Set volume selection
switch to the "I POT" setting. To brew into a regular 60 oz. decanter, little adjustment should be needed. Turn timer dial
clockwise to increase volume of water, and counter clockwise to decrease volume. The "II POT" setting will
automatically be set to deliver twice the volume of water as the "I POT" setting. If the brewer has 3 volume selections the
“III POT” setting will deliver three times that of the “I POT” setting. The dial labeled “Visa” on the timer may be set for an
additional amount of time to flash the brew indicator on the faceplate to allow for time for the coffee to finish draining
from the brewbasket after the fill cycle has completed.
3) Some GX model brewers incorporate an independent manual by-pass system. You can pass-up this step if your
brewer does not have a by-pass system. by-pass calibration is done from brewer exterior. Locate the two screws on the
front right side panel. See diagram below. These screws are your adjustment. Unless customer specified, Brewer is
shipped with by-pass in the closed position.
Procedure:
a) IMPORTANT - Set the brewer volume first. See step 2 above.
Once set, the by-pass does not affect total brew volume due
to the design. The brew system calibration is based upon
timing the water into the brewer which we call, fill time.
Brew time is the amount of time it takes to siphon the water
out of the tank through the sprayhead.
b) To adjust by-pass, turn both screws one full turn
counter clockwise. This should deliver approximately a 10
% by-pass.
c) To measure your by-pass, refer to the chart below to give you
the range available. The procedure is very simple.
USE CAUTION WHEN WORKING WITH VERY HOT WATER.
Remove the brew basket from the brew rails and position a metal container to collect the water from the
sprayhead. The by-pass outlet is located in the right corner of the brew plate. Position a measuring container
under the outlet and initiate a brew cycle, water will begin to flow out of the sprayhead and then out of the
by-pass. At the point the by-pass begins flowing freely, time and collect 30 seconds of water and compare the
volume with the chart below to determine your % of by-pass.

d) This system is designed to allow you to adjust brew-steeping time to enhance the recipe of the coffee being
brewed. Bypassing is used when brewing large volumes of coffee. NEWCO has three Brew Baskets available.
Brewer comes standard with Plastic Color Changing Basket P/N 701714
4) For 120 V units the brewer is shipped with thermostat turned on. 240 V units have the thermostat shut off. Turning
the thermostat knob clockwise will increase the water temperature in the tank and counterclockwise will decrease it.
5) Allow 10 to 15 minutes for water in tank to heat to brewing temperature. (Additional water may drip from brew basket
due to initial expansion of water in the tank). This will not occur thereafter.
