FRESH-TRAC TIMER
Fresh-Trac Receiver
These instructions will explain the operation and maintenance of the Fresh-Trac coffee timer. This timer will allow the
user to track the freshness of coffee brewed into glass decanters. Fresh-Trac is only available with Curtis Alpha GT
brewers. A ashing light inside the decanter handle signals when the coffee is no longer fresh.
All changes to the timer settings are made at the Alpha’s UCM (Universal Control Module). See Resetting the Timer, on page two. Earlier Alpha
UCM controllers do not have the Fresh-Trac feature.
The Fresh-Trac timer uses a visual alarm in the form of a ashing light.
When a new brewcycle begins, you will observe ve quick ashes indicat-
ing that the timer has started. Timing data is transmitted to the Fresh-Trac
receiver on the decanter. The timer adjustment range is from 10 minutes to
120 minutes. The factory setting is 30 minutes (default time in the UCM).
When time has expired, the Fresh-Trac will light every ve seconds. The
light will turn off completely after one hour or unless you brew again into
the same decanter.
The Fresh-Trac decanter is dish-washer safe. The expected battery life in the light unit is two years. The battery is not
replaceable.

Cleaning the Coffee Brewer
Regular cleaning and preventive maintenance is essential in keeping your coffee brewer looking and working like new.
CAUTION – Do not use cleansers, bleach liquids, powders or any other substance containing chlorine. These
products promote corrosion and will pit the stainless steel. USE OF THESE PRODUCTS WILL VOID THE
WARRANTY.
1. Wipe exterior surfaces with a moist cloth, removing spills and debris.
2. Slide the brew cone out and clean it. Clean the spray head area with a moist clean cloth.
3. Rinse and dry the brew cone.
4. Drain drip tray of coffee. Wash out the drip tray. Dry the tray.
5. Rub a stainless steel polish on the outside surfaces to protect the brewer.
Cleaning Glass Decanter
Curtis glass decanters are dish-washer safe. Coffee decanters may be hand washed.
1. Prepare a mild solution of detergent and warm water.
2. Immerse the decanter in detergent solution and clean with a sponge brush.
3. Thoroughly rinse out the glass decanter with clean warm water.
4. Dry the decanter.
WARNING – To Avoid Damage or Injury
l Do not boil dry or heat pot when empty.
l Do not clean with materials that scratch.
l Do not use gas ame or range top of any kind.
l Do not pour towards people.
l Do not carry two decanters in one hand.
l Clean only with mild detergent or an urn cleaning solution specically intended for coffee decanters.
Liquid Level Probe
Cleaning intervals for the probe are to be determined by the user or the service
tech, based on water conditions. The use of water lters, or the type of water lter
that is being used can impact the service interval. Intervals can be from one month
to several years, however, replacing rather than cleaning the probe is preferable.
WARNING: Disconnect electrical power before removing access panels!
This procedure involves working with hot water and hot surfaces!
1. Unplug the power cord and shut off the water line.
2. Remove the top cover of the unit. Locate the top of the tank and remove the
cover.
3. Drain the tank to a level about 3” below the tip of the probe.
4. Allow some time for the probe to cool before working on the brewer.
5. Clean the tip of the probe using a Scotch-Brite™ scuff pad.
6. If scale is still visible, remove the probe and soak it in vinegar or a scale removing chemical.
7. When assembling the probe back onto the tank, make sure the tip of the probe
is pointing downward as illustrated.
