safety and efficiency
To ensure the safe and efficient operation of your Hot Cup it is important to descale
it regularly. The harder your water the more regularly it will need doing. Your water
company should be able to tell you how hard the water is in your area. Untreated scale
deposits prevent the element conducting heat efficiently therefore wasting electricity.
Scale can also cause your Hot Cup to malfunction or even cause premature failure.
Descaling using a proprietary descaling product
1. Fill your Hot Cup to the MAX fill level and place an empty cup on the drip tray. Set the
on/off switch to the on position and wait for the water to be dispensed into the cup.
2. Add a citric acid-based proprietary descaling product to the hot water in the cup and
stir.
3. Tip the contents of the cup into your Hot Cup and close the lid.
4. Place the empty cup on the drip tray and set the on/off switch to the on position.
5. Wait for the water to be dispensed into the cup.
6. Discard the water from the cup.
7. Repeat steps 4, 5 and 6 until the water level is at the MIN mark. Open the lid and
empty any remaining water into the sink. Rinse your Hot Cup by filling it with clean
water and emptying it into the sink (see Emptying your Hot Cup on page 6).
Fill your Hot Cup with fresh water to the MAX fill level and place an empty cup on the
drip tray.
8.
Set the on/off switch to the on position and wait for the water to be dispensed into the
cup.
9.
Discard the water in the cup. Repeat steps 8 and 9 until the water level is at the MIN
mark. Open the lid and empty any remaining water into the sink (see Emptying your
Hot Cup on page 6).
Descaling using vinegar or citric acid
1.
You can use ordinary vinegar (white or malt) or citric acid to descale your Hot
Cup. Inexpensive, ordinary vinegar can be purchased in large bottles from any
supermarket. Citric acid can be bought from pharmacies, home brewing/winemaking
suppliers or on-line retailers.
2.
If you are using vinegar, make up a solution of 1 cup of vinegar to 1 cup of water. If
you are using citric acid, mix 30g of the citric acid with 500ml of water.
3.
Pour the solution into your Hot Cup, close the lid and allow it to stand for 1 hour.
4.
Cycle your Hot Cup (as described in steps 4-6 above) until the level is at the MIN
mark. Open the lid and empty any remaining solution into the sink. Rinse your Hot
Cup several times by filling it with clean water and emptying it into the sink.
5.
Fill your Hot Cup with fresh water to the MAX fill level and place an empty cup on the
drip tray.
6.
Set the on/off switch to the on position and wait for the water to be dispensed into the
cup.
7.
Discard the water in the cup. Repeat steps 6 and 7 until the water level is at the MIN
mark. Open the lid and empty any remaining water into the sink.
8.
Finally, rinse your Hot Cup several times with clean water.
