Sanitation Requirements
NSF International requires the following water connection:
1. A quick disconnect or additional coiled tubing (at least 2x the depth of the unit) is required so
that the unit can be moved for cleaning.
2. This unit must be installed with adequate backow protection to comply with applicable federal,
state and local codes.
3. Water pipe connections and xtures directly connected to a portable water supply shall be sized,
installed and maintained in accordance with federal, state, and local codes.
3. Connect the unit to electrical outlet with appropriate amperage rating (see serial tag on machine).
4. Once power has been supplied to the unit, ip the toggle switch to the ‘ON’ position (located on the rear of
the unit), the water tank will begin to ll. When the water level in the tank reaches the probe, the heating
element(s) will turn on.
5. Water in the heating tank will require approximately a half hour before reaching operating temperature
(factory setting of 200°F). Where applicable, turn on the Universal Control Module (UCM). When the unit
reaches operating temperature, it will display “READY TO BREW”.
NOTE: A water ltration system must be used to help maintain trouble-free operation. In areas with
extremely hard water, we highly recommend the use of a Curtis approved water lter. For our full line
of lters, please log on to www.wilburcurtis.com. A water ltration system will greatly prolong the life
of the unit and enhance the quality and taste of the product.
SETUP STEPS
1. The unit should be level (left to right - front to back), on a secure surface.
2. Connect the water line to the water inlet tting on the rear of the unit. Water volume ow to the machine
should be consistent. Use tubing sized sufciently to provide a minimum ow rate of one gallon per minute.

Cleaning the ThermoPro
Regular cleaning and preventive maintenance is essential in keeping your coffee brewer looking and working like new. To clean the coffee
brewer and components, prepare a mild solution of dish washing detergent and warm water.
CAUTION – Do not use cleansers, bleach liquids, powders or any other substance containing chlorine. These products promote corrosion and
will pit the stainless steel. USE OF THESE PRODUCTS WILL VOID THE WARRANTY.
DAILY CLEANING
1. Wipe exterior surfaces with a damp cloth, removing spills and debris.
2. Slide the brewcone out and clean it. Wipe the sprayhead area with a cloth soaked in a mild detergent solution.
3. Rinse with a cloth soaked with clean water. Dry the brewcone and sprayhead area.
4. Drain drip trays of coffee. Water rinse.
5. Dry the tray.
WEEKLY CLEANING
1. Reach behind the brewer and turn off the power at the toggle switch. Allow the brewer to cool.
2. Clean the sprayhead and dome plate area.
a. Remove the sprayhead, unscrewing counterclockwise from the dome plate.
b. Thoroughly clean and rinse the dome plate area.
c. Clean the brewcone rails with a brush soaked with a mild detergent solution. Rinse the area with a cloth soaked with clean water,
removing any residual detergent.
d. Dry the area.
c. Attach the sprayhead.
Cleaning the Thermoserver

2. Fill the liner with a mild detergent solution and let it stand for 10 to 15 minutes.
3. After about 15 minutes take a sponge brush and scrub out the stainless steel liner.
4. When clean, drain out the soapy solution from the server.
5. Fill the server with clean water to rinse detergent from inside the unit. Repeat this rinsing until the water runs clear.
CLEANING OF THERMOSERVER FAUCET
1. Remove the faucet handle assembly. Take hold of the bonnet and turn counterclockwise to unscrew it from the faucet.
2. Clean the handle assembly with a mild detergent solution. When clean, rinse the handle with water. Inspect for cracks
or tears in the seat cup. Replace if damaged.
3. Clean the coffee level gauge glass.
