• Brew Volume = Set to dispensing vessel requirements (2.2 liters)  
Generally there will never be a reason to change your ADS programming. However, should you need to make slight adjustments  
to meet your brewing needs, programming instructions are provided later in this manual.  
CAUTION: DO NOT  
connect this brewer to  
hot water. The inlet valve

• Water Source 20 – 90 PSI (Minimum Flow Rate of 1 GPM)

is not rated for hot water.  
SETUP STEPS  
The unit should be level (left to right and front to back), located on a solid counter top. Connect a water line from the water filter to the  
brewer. NOTE: Some type of water filtration device must be used to maintain a trouble-free operation. (In areas with extremely hard  
water, we suggest that a sedimentary and taste & odor filter be installed.) This will prolong the life of your brewing system and  
enhance coffee quality.  
CAUTION: When  
cleaning, DO NOT use  
powders, liquids,  
cleansers, or any substance  
containing chlorine. These  
products promote corrosion,  
cause pitting of stainless steel and  
will void the warranty.  
The National Sanitation Foundation requires the following water connection:  
1. A quick disconnect or additional coiled tubing (at least 2x the depth of the unit) so that the machine can be moved  
for cleaning underneath.  
2. In some areas an approved backflow prevention device may be required between the brewer and water supply.  
1. A 3/8” NPT x 1/4” Flare elbow has been supplied for water line connection. Use tubing sized sufficiently to provide a minimum of  
1.0 GPM.  
2. Connect the unit to an appropriate electrical power circuit.  
3. Turn on the toggle (STANDBY/ON) switch behind the unit. The heating tank will start to fill. When the water level in the tank rises  
to the correct volume, the heating elements will energize automatically. With ADS Systems there is no danger of element burnout  
caused by an empty tank.  
4. The heating tank will require 20 to 30 minutes to reach operating temperature (200°F) as indicated by the READY-TO-BREW  
indicator light.  
5. Prior to brewing, dispense 12 ounces of hot water through the hot water faucet.  
6. Brew a cycle of at least 12 ounces, to purge the water lines of any air that may be trapped after filling.  
BREWING INSTRUCTIONS  
1. Brewer should be ON (Confirm at rear toggle switch, then press ON/OFF button). Ready-to-Brew should be displayed.  
2. Place empty airpot on deck.  
3. Place filter in brewcone.

Pulse Brew (Factory set to OFF)  
Press to select, < or > to select OFF or one of four pulse patterns (A to D) .  
Guidelines for Pulse Brew:  
This feature allows tuning of the coffee flavor.This option should only be used with the standard Gray or Purple AFS sprayheads.The pot level should always be set first with this option OFF.  
Depending on your grind profile and water conditions, the three Pulse Brew options help “tuneor change the coffee flavor. Filter Pack type coffees typically extract better with theA and B pulse setting.  
Decaffeinated coffees typically extract better with the B pulse setting. High-Yield coffees typically extract better with the C pulse setting. Of course, any of the A, B or C settings may be used to suit your taste  
profile.  
If Pulse Brew is selected (ON), Cold Brew Lock is set to Delta 1 within 5ºF of set point and Cold Brew Lock disappears from the list of program selections.  
When Pulse Brew is ON, Pre-infusion disappear from the list of program selections.
