Descaling Your Water Cooler - Whirlpool 8LCH-KKSCSSS5HW User Manual

DESCALING YOUR WATER COOLER

Your coffee brewer water cooler has a low watt density, external hot water tank heater.
It has a larger area to spread heat compared to the ordinary internal water heating el-
ements found in other water coolers. You may experience a gradual buildup of mineral
scale or calcium deposits, depending on the mineral content of your water. The build-
up occurs at a much slower rate than with internal heaters. Mineral scale is non-toxic,
however it can affect the brewer's performance by interfering with the internal valves.
Descaling your brewer helps maintain the parts that come in contact with water.
If you are using mineral or filtered water, your brewer should be descaled 6 months to
one year to ensure optimal performance or whenever there are white deposits coming
out of 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.
Descaling
If you use spring (mineral) water you will need to de-scale your hot water tank.
Heated spring (mineral) water will cause minerals to fall out. Eventually they will plug
up your waterways, resulting in a gradual slowdown of the flow rate, leaking faucets,
and other problems.
Descaling Solutions
Cooking vinegar is proven to remove calcium deposits efficiently.
Depending on the frequency of decalcification treatments, please use the following pro-
portions of White Vinegar.
- For descaling once every three months, use two cups (500 ml) of white vinegar with
2.5 liters of hot water.
- For descaling once every six months, use a mixture of six cups (1500 ml) of white
vinegar with two liters of hot water.
- For descaling once every year, use 12 cups (3000 ml) of white vinegar and one liter
of hot water.
- For descaling less frequently than once a year, use undiluted white vinegar.
Descaling Procedure
1. Turn off hot & cold switches.
2. Unplug the cooler from the wall.
3. Using rear drain plug, drain the water from the cooler into a bucket and discard the
water.
a. Locate the white plastic cap at the back of the cooler.
