Timer Adjustment:
The timer has two independent settings, with three dials for each setting. The first dial in each group sets 100
second increments, the second dial sets 10 second increments, and the third dial sets 1 second increments.
A red LED lights when the power to the timer is on. A yellow LED lights when the timer is running.
A small flat head screwdriver is required to adjust the dials.

Water Level Control Board:
The board features a jumper to adjust its’ sensitivity for reverse osmosis or other types of ultra-pure water.
The default jumper setting is LO (50K ohms) for normal water. If the brewer tank overfills because of ultra-
pure water, the jumper should be set to HI (100K ohms).
A red LED lights when the power to the board is on.
A green LED lights when the water level probe detects that the tank is full.
A yellow LED lights when the FILL circuit is energized.
A second yellow LED lights when the HEAT circuit is energized.
Bypass Adjustment:
The purpose of the bypass valve is to allow a portion of the brewing water to flow between the brew basket and the
wire insert, directly into the server, without coming in contact with the coffee grounds. The bypass can be adjusted
from 0% to 33% of the total brewing water. Dual brewers (CBS-52H), have separate bypass valves on each side.
Unless requested at the time of order, all brewers are shipped with the bypass valves closed (0%). Adjusting the
bypass always changes the total brew volume, so the timer setting must always be checked and adjusted.
To adjust the bypass:
•
Remove the brewer’s upper cover.
•
The bypass valve is located above the brew basket, to the right and to the front, as you are facing it.
•
Remove the brew basket.
•
Place a container under the spray head, and a separate container under the bypass hole.
•
Turn the bypass valve clockwise to decrease, and counter-clockwise to increase the bypass amount.
A good starting point would be one full turn for each 5% change.
•
Brew a full cycle and measure the amount of water in both containers.
•
The ratio of the bypass water to the total in both containers is the bypass percentage.
example: ½ gal. 1 gal. from spray head = 1 ½ gal. total. Bypass = 33.3%.
•
Several adjustments may be necessary until the desired results are achieved.
