Descaling Your Coffee Brewer/Water Cooler - Glacial 8LCH-KK-SC-SSF-40 User Manual

DESCALING YOUR COFFEE BREWER / WATER COOLER
Your brewer and water cooler share a low watt density, external hot water tank heater. If has a larger
area to spread heat comparing to ordinary internal water heating elements. You may experience a
buildup of mineral scale or calcium deposits, depending on mineral content of the water. Still, build up
occurs at a much slower rate than with an internal heaters. Mineral scale is non-toxic, however it can
affect the brewer's performance by interfering with internal valves. Descaling your brewer helps main-
tain clean internal parts that come in contact with water.
If you are using mineral or filtered water, the brewer should be descaled every year to ensure optimal
performance or whenever there are white deposits in the hot water tank. It is possible for calcium
deposits to build up faster, making it necessary to descale more often. If you use distilled or RO water
descaling is not required.
This is how to descale your hot water tank:
Step 1. Make sure you have one gallon of undiluted white vinegar on hand.
Step 2. Switch off the cooler by unplugging power cord. Remove the 5 gallon bottle. Drain all the
water out through the drain at the back. Replace the drain plug.
Step 3. Place the probe into the container with undiluted vinegar.
Step 4. Plug the power cord into an outlet. Hold the reset switch for the door to start the cooler and
get the pump working. Fill the cooler with vinegar.
Step 5. Check if hot tank is full of vinegar by dispensing it from hot water faucet.
Step 6. If you cannot close the door with vinegar container inside, then remove container and close
the door.
Step 7. Turn on the Hot Water Switch (see #15 on page 10) and allow it to sit for at least 30 minutes.
Step 8. Dispense small cup of vinegar from coffee dispensing nozzle and 1/2 of small cup from Hot
and Cold water faucets every 10 minutes for 1/2 an hour.
Step 9. After the prescribed period of time, unplug the cooler, drain the vinegar through the drain on
the back.
Step 10. Rinse by closing the drain and placing a 5 gallon bottle or other container with tap water
inside of the compartment with the probe inserted into it. Plug the cooler back in to fill the hot
and cold tank with tap water.
Step 11. Rinse with tap water until smell goes away .
Step 12. Turn on the Hot Water Switch (see #15 on page 10) and allow it to sit for at least 30 minutes.
Step 13. Drain the water through the back drain again by following previous instructions.
Step 14. Repeat rinsing until the vinegar smell is gone and there is no sign of calcium deposits left
(they may get dissolved or show up as small white crystals).
Step 15. Place the 5 gallon bottle back and enjoy your brewer/water cooler once again.
