Care And Cleaning - Grindmaster ICB-300 Operation Manual

BYPASS ADJUSTMENT (Refer to Figure D)
The bypass valve adjusts the amount of water that bypasses coffee grounds and dilutes the
final brew. The factory setting is no bypass.
Bitter coffee results when the amount of ground coffee is too small. Therefore, if coffee is too
strong, it is better to adjust the bypass rate instead of reducing the amount of coffee.
NOTE: Always adjust bypass before adjusting brew time because bypass affects
brew rate.
• Turn off electrical power to brewer and remove top cover.
• Locate the bypass valve to be adjusted. The bypass valve is located to the right and in
front of the brew tee.
• Open the valve by turning the valve handle counterclockwise to the desired setting.
(Refer to information below.)

• Measure the bypass setting:
a) Remove the brew basket.
b) Place an empty shuttle (with lid removed) under the sprayhead.
c) Place a measuring cup under the bypass outlet.
d) Press START and brew water for about 30 sec. or until measuring cup is almost full.
e) Record the amount of water in the bypass measuring cup.
f) Add the water from the measuring cup to the shuttle; measure total volume and record.
Bypass % = (Bypass Volume/Total Volume) X 100
• Adjust the bypass valve setting and repeat measuring process until valve is set as desired.

CARE AND CLEANING

WARNING: BURN HAZARD! HOT LIQUIDS AND SURFACES ARE PRESENT IN THIS EQUIPMENT. TO AVOID BURNS, USE CAUTION
WHEN CLEANING. RINSE HOT PARTS WITH COLD WATER BEFORE CLEANING. USE GLOVES OR A HEAVY CLOTH WHEN REMOVING
HOT PARTS FROM BREWER.
EVERYDAY
• Wash the brew baskets with warm, soapy water. The wire basket can be removed to aid cleaning of the brew basket.
• Remove the spray heads that are located above the brew baskets using gloves or a heavy towel. Wash to remove any coffee oils and to
clean any plugged holes.
• Clean shuttles and insulated containers with warm, soapy water and a plastic or non-abrasive brush or towel.
• Clean airpots with warm, soapy water and a bottle brush. Take care not to break the glass interior. Use only a soft cloth and warm, soapy
water or stainless steel polish on the outside to avoid scratching exterior surface.
• Wipe the exterior of the brewer with a damp cloth. Do not use abrasives, which can scratch brewer surfaces.
• If shuttles are to be left on warmer overnight, fill with water to avoid coffee oil burn-in.
WEEKLY OR BIWEEKLY, DEPENDING UPON USE
• Fill the shuttle, airpot or insulated container with hot water to about 2/3 full.
• Pour the recommended amount of urn cleaner into the container. (Excessive amounts of cleaner will attack the stainless steel lining of the
shuttle and insulated container.)
• Scrub the liner interior with a plastic bristle brush.
• Remove the knurled nut at the top of the gauge glass and clean the glass with a small bottle brush.
• Pour out the contents of the shuttle.
• Remove the handle assembly of the shuttle or insulated container faucet by unscrewing the plastic bonnet.
• Gently wash the faucet seat cup with a soft cloth and warm, soapy water.
• Wash the faucet shank with a bottle brush.
• Soak the airpot pick-up tube assembly in hot, soapy water. Urn cleaner may be used for stronger cleaning.
• Clean the warmer and bottom of shuttle surfaces; these surfaces must be clean for proper heat transfer.
• Polish the exterior of the brewer with stainless steel cleaner. Use the appropriate cleaner for brass, copper or vinyl if these optional finishes
are provided.
