KEY FEATURES/SPECIFICATIONS/SYSTEM REQUIREMENTS FS19
Key Features
• Digital Control Module provides precise control over all brewing aspects: time, temperature, volume plus
specialty coffee needs from pre-infusion to pulse-brewing to water bypass.
• Siphon Technology – During the brewing process, the brew basket’s siphon allows for the water level to rise to
the perfect level without exiting. A pre-infusion in its purest form, this patented feature produces the true promle
of the intended roast taste and experience.
• The Brew Basket – Uniform ridges gently hold the mlter away from the sides and bottom to allow for optimum
extraction. Patent pending, years went into the concept and the development of the brew basket to perfect the
brewing process and provide the Golden Cup coffee results.
• Pre-Wet/Wash Filter Function – Many shops pre-wet their mlters in an effort to remove any paper taste from
interfering with the mnished brew. The Curtis Gold Cup has a pre-wet function that streams hot water over the
paper mlter to eliminate any undesirable paper taste prior to brewing.

Installation
Installing the Leg Support Plate
(Optional on CGC Series Models)
For ease of installation, the brewer may be laid on its
side to allow access to the bottom. Lay the unit on a soft
padded surface to avoid scratches.
1 Remove the four legs from the bottom of the brewer
by unscrewing them. The front legs are different
from the rear legs. Note the location and difference
between the two types during removal.
2 Place the leg support plate on the bottom of the unit.
Line up the leg holes in the plate with the leg holes on
the bottom of the unit.
3 Reinstall the legs in the same positions they were
removed from in step 1.
Leveling
4 Position the unit on the countertop. Level it left to right
and front to back by turning the bottom of the legs.
