This equipment is designed for commercial use. Any servicing other than cleaning and routine
maintenance should be performed by an authorized Wilbur Curtis Company Service Technician.
• DO NOT immerse the unit in water or any other liquid
• To reduce the risk of fire or electric shock, DO NOT open service panels. There are no
user serviceable parts inside.
• Keep hands and other items away from hot areas of the unit during operation.
• Never clean with scouring powders or harsh chemicals.
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, flip the toggle switch to the ‘ON’ position (located on the rear of
the unit), the water tank will begin to fill. 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 one hour before reaching operating temperature (factory
setting of 190°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 filtration system must be used to help maintain trouble-free operation. In areas with ex-
tremely hard water, we highly recommend the use of a Curtis approved water filter. For our full line of filters,
please log on to www.wilburcurtis.com. A water filtration 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 fitting on the rear of the unit. Water volume flow to the machine
should be consistent. Use tubing sized sufficiently to provide a minimum flow rate of one gallon per minute.
