WATER HOOK UP  
The National Sanitation Foundation (NSF) requires the following for NSF approved installation:  
1. A quick disconnect water connection or enough extra coiled tubing (at least 2x the depth of the unit)  
so that the Brewer can be moved for cleaning underneath.  
2. An approved flow-back prevention device such as a double check valve to be installed between  
Brewer and water supply.  
WATER CONNECTION  
The Brewer comes equipped with a ¼ inch flare water inlet fitting located in the back. Use a ¼ inch  
copper tubing to connect the Brewer to a cold water supply. Water pressure should be: 20 PSI min. to  
90 PSI max. An external shut-off valve and a water filtering system with a charcoal filter are highly  
recommended.  
Turn water supply on and check for leaks at the water inlet connections, tighten flare fitting if necessary.

SPECIAL COMPONENTS TEST AND ADJUSTMENTS  
1) WATER INLET VALVE (SOLENOID) TEST (Located inside bottom cabin)  
Turn power off from touchpad. If the water level rises inside the tank, and shoots out  
of the overflow, the Water Inlet Valve is leaking. Disconnect wires from the Water Inlet  
Valve coil and connect a 2 wire line cord to the terminals. Plug it into a 115V outlet. If  
water flows in and stops when you pull it out, the Valve is working fine. Repeat this  
test a few times. The problem may be in the Probe. If the water does not flow in  
when the cord is plugged into an electrical outlet, the Solenoid coil may be damaged,  
opened or the valve may have an obstruction preventing the water from flowing in.  
Clean or replace it.  
A Check Valve is installed to prevent backflow.  
To check proper function of Check Valve, disconnect water line from the Check  
Valve, check for dripping from the disconnected end of the Check Valve.  
If it leaks replace it.  
Water inlet Valve max. flow rate is 1.3 gal/min.  
2) WATER LEVEL PROBE TEST (Located on tank top, inside top cabin)  
If there is a lack of water, you will get an error message on the LCD window.  
Check the probe as follows:  
Turn on the power from touchpad and water supply. Check inside the tank to make  
sure the water is not touching the Probe. Pull the wire and terminal out of the  
Probe rod. If water starts flowing into the tank, the Probe may be grounded, due to  
excessive liming. Check with Ohm meter. Clean or replace.  
3) POWER SAFETY RELAY TEST (Located inside top cabin)  
Turn power switch on from touchpad. Measure Voltage across Input to Coil,  
between terminals1& 2. Should read approx. 9V to 10V D.C.  
Measure Voltage across Input, between terminals “COM” to Ground. Should read 120V.  
Measure Voltage across Output, between terminals “NO” to Ground. Should read 120V.  
4) HEATER SAFETY RELAY TEST (240V UNITS ONLY) (Located inside top cabin)  
Make sure power switch in back of unit is on (toggle up).  
Turn power switch on (energize) from touchpad. Measure Input Voltage across coil,  
between terminals 0 & 1. Should read 120V.  
Measure Output Voltage across Heater Element. Should read 220 V. If there is no  
Voltage across the Heating Element, measure Output Voltage between terminals 4 & 8.  
Turn power switch off from touchpad. The Voltage should be a constant 220V even when not energized.  
Turn power switch on) from touchpad. Measure Voltage across terminals 2 & 6. Should read 220V.  
If 120V was applied to relay coil and it does not energize, replace relay.

5) CHECK DISPENSE VALVES FOR LIME BUILD-UP (Located inside top cabin)  
Drain The Water Tank To Just Below The Level Of The Dispense Valves.  
Remove The Valves And Clean. You Can Take These Valves Apart By Hand As Shown.  
Replace The Assembly As Needed.  
Replace The Valve Into The Tank And Refill tank.  
The SINGLE DISPENSE VALVE is factory adjusted to dispense  
0.35 oz./sec. of water during the brew cycle (spray duration).  
TO ADJUST WATER FLOW RATE:  
Locate adjustment screw on valve (as show here).  
Using an Allen Key or a flat screwdriver, rotate ¼ turn at a time,  
Clockwise (CW) to decrease water flow rate or  
Counter-Clockwise (CCW) to increase water flow rate.  
Check water flow output after each ¼ turn.  
CLEANING AND SANITIZING  
SANITIZING:  
All food dispensing units should be sanitized periodically. All parts to be sanitized must be cleaned first.  
To prepare a sanitizing solution:  
ADD 2 TSP. OF LIQUID CLOROX BLEACH (5.25% CONCENTRATION) TO 1 GALLON OF WATER AT ROOM TEMPERATURE (70°- 90°F).  
Note: Always start with a unopened bottle of Clorox Bleach since the solution from an opened bottle has a short life span.  
• Soak all parts for a minimum of 3 min. in the sanitizing solution.  
• Let all sanitized parts drain and dry naturally. DO NOT WIPE THEM DRY.  
• Before using the sanitized unit (or parts) with food stuffs, rinse all parts thoroughly with water.  
Water pipe connecting and fixtures directly connected to a potable water supply shall be sized, installed, and maintained in accordance  
with Federal, Sate, and Local codes (section 7).  
CLEANING:  
1. Empty contents from brew funnel, wash and let dry (use a mild dishwasher detergent).  
2. To wash machine surfaces, first turn power switch OFF, wipe down machine surfaces, then turn power switch ON.
