Safety
Note
DO NOT connect this brewer to a hot
water supply. The water inlet valve is
not rated for hot water.
Do not exceed the maximum water
pressure stated in the technical data
section.
Installation Requirements
• For units without an attached cord set attached:
Appropriately sized, VDE listed, grounding type power cable
tp meet the electrical specifications for the appliance. If you
have questions about the correct cable size and length, consult
a qualified installer. If the appliance will be hard wired to a
junction box, the power cable must be long enough so that the
unit can be moved for cleaning underneath.
• A grounded electrical connection to an electrical circuit
that meets the electrical specifications of the appliance
(see Technical Data). The circuit must be protected by the
appropriate sized circuit breaker. If you are not certain that the
existing circuit meets the requirements for your unit, consult a
licensed electrician.
• A water filtration system is required to maintain trouble-free
operation. Wilbur Curtis Co., Inc. recommends a Wilbur Curtis
approved water filter.
• Potable water supply line connection from the water filter
capable of supplying the minimum flow rate required by the
specifications. The water supply line must be able to connect to
the flare fitting on the back of the unit. See Technical Data for
the correct size.
NOTE
