CLEANING AND DESCALING
To clean the outer body of Oyu, use a damp cloth or sponge and wipe clean. Dry with kitchen paper or
another dry cloth.
To ensure the safe and efficient operation of your Oyu Smart Instant Hot Water Dispenser, it is necessary
and important to descale it regularly. If you live in a hard water area, it will need descaling more
regularly than normal (check with your water company what type of water area you live in).
If you do not descale/clean your Oyu, scale deposits prevent the heating element from conducting the
heat efficiently and wastes electricity. Scale will also cause your Oyu to malfunction or fail. We advise
that in a normal water area you descale every 2 months.
You can descale in two ways – you can use a kettle cleaner product or you can use vinegar or citric acid
powder.
Descaling using a kettle cleaner
1.
Fill the water tank halfway (i.e. 2 litres) and place a measuring jug underneath the dispense
spout. Dispense 500ml of maximum temperature water into the jug.
2.
Add the kettle cleaning product to the hot water and stir until it’s dissolved.
3.
Pour the contents of the jug back into the water tank and put the lid on.
4.
Place the measuring jug back under the dispense spout and dispense 500ml, discard the
water.
5.
Keep dispensing and discarding until the water tank is empty and the E2 error shows on the
display.
6.
Fill with fresh water and repeat steps 4 and 5.
7.
Rinse the water tank by filling with clean water and emptying, do this several times.
8.
Fill with fresh water and repeat steps 4 and 5, once at the minimum level, empty the
remaining water out and refill with fresh water.
Descale using vinegar or citric acid
1.
You can use powdered citric acid or ordinary vinegar (malt or white) to descale your Oyu.
2.
Using vinegar, make up a solution of 1 cup of vinegar to one cup of hot water. Add this to the
water in the tank (as above, fill to 2 litre mark). If using citric acid, mix 30g of citric acid with
500ml of hot water. Add this to the water in the tank (as above, fill to 2 litre mark).
3.
Allow to stand for 1 hour, then dispense the water as described above in steps 4 and 5.
4.
Discard any remaining water and rinse the water tank several times in clean water (until there
is no smell).
