Sanitation Requirements
NSF International requires the following water connection:
1. A quick disconnect or additional coiled tubing (at least 2x the depth of the brewer) is required so
that the brewer can be moved for cleaning.
2. This brewer 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.
4. Connect the brewer to electrical outlet with an appropriate amperage rating (see serial tag on machine).
5. Once power has been supplied to the brewer, 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.
6. Water in the heating tank will require approximately a half hour before reaching operating temperature (fac-
tory setting of 204°F). Turn on the universal control module (UCM). When the brewer 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 the 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 INSTRUCTIONS
1. The unit should be level (left to right - front to back), on a secure surface.
2. Install the hot water faucet as instructed on page 2.
3. Connect the water line to the water inlet fitting on the rear of the brewer.
The water volume flow to the machine should be consistent. Use tubing
sized sufficiently to provide a minimum flow rate of one gallon per minute.
CAUTION: DO NOT
connect this brewer to hot
water. The inlet valve is
not rated for hot water.
CAUTION: Follow these
setup instructions before
attempting to use this
brewer. Failure to follow the instruc-
tions can result in injury or voiding of
the warranty.
