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-flow 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 an 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”.
NOTE: A water filtration system must be used to help maintain trouble-free operation. Air must be
purged from the cartridge prior to connection to equipment. 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.
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.
