Sanitation Requirements
Your Curtis Café System is Factory Pre-Set and Ready to Go... Right from the Carton.
Following are the Factory Settings for your Soluble Delivery System:
• Tank Temperature = 190°F
• Flavor Controls= Set at 50%
• Dispensing Mode Set for Manual Dispensing
Generally there will never be a reason to change your SD2 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.
Equipment to be installed to comply with applicable federal, state, or local plumbing/electrical codes having jurisdiction.
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 dispensing system and enhance
coffee quality.
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 the water supply.
1. Connect a water line from your facility to the 1/4" flare water inlet fitting of the valve, behind the machine. Water volume
going to the machine should be stable. Use tubing sized sufficiently to provide a minimum flow rate of one gallon per minute.
2. Plug the power cord into an electrical outlet rated at 20A.
3. Switch on the toggle switch, behind the unit, that runs power to the components in the machine. The lights (display window
and row of buttons) on the front door will activate and the heating tank will start to fill.
4. Water in the heating tank will require about 30 minutes to reach operating temperature (factory setting of 190°F). At this time
the READY LED will light.
5. Remove and fill the canisters with soluble coffee mixes.
OPERATION INSTRUCTIONS
1. Select one of the coffee dispense buttons.
2. Place your cup beneath the spout of the desired coffee flavor.
2. Press and hold the selected PUSH button. Hot coffee beverage will start dispensing.
3. Release the button when the cup is 2/3 full.
FILL CANISTERS DAILY
1. Open the front door to access the coffee canisters.
2. The canisters must be removed from the unit for filling. Turn the product delivery elbows upward.
3. Reposition the canisters on the machine, turning the product delivery elbows downward and aligning the gear socket with the
motor shaft.
