Sanitation Requirements
This Curtis Generation 3 Unit is Factory Pre-Set and Ready to Go Right from the Box.
Following are the Factory Settings for your Expressions Multi-flavor Beverage System:
• Tank Temperature = 190°F
• Dispensing Mode Set for Manual Dispense
Generally there will never be a reason to change your G3 programming. However, should you need
to make slight adjustments to meet your dispensing needs, programming instructions are provided
later in this manual.
System Requirements:
• Water Source 20 – 90 PSI (Minimum Flow Rate of 1 GPM)
• Electrical: See attached schematic for standard model or visit www.wilburcurtis.com for
your model.
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.
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.
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 backflow protection to comply with applicable federal,
state and local codes.
3. Water pipe connections and fixtures 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, 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".
