INSTALLATION
This Curtis unit is pre-set and ready to go from the factory.
Factory settings for this unit are:
• Brew Temperature = 200°F
• Brew Volume = Set to vessel requirements (1 Gallon).
System Requirements:
• Water Supply 20 – 90 PSI (minimum flow rate of 1 gpm)
• Electrical: See electrical schematic.
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 extremely 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 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".
