Zanussi ZBS 862 manual Cleaning the exhaust pipe, Using different water types

-When water stops flowing out the water tank, turn the pipe connector clockwise to close the exhaust-valve.

Warning! - The connector "A" has not a block fitting. Take care this connector doesn't slip off the pipe during the water tank exhaust procedure.

-After the water tank has been drained, melt two spoonful of citric acid (about 50-60 grams) into 800 cc. of water.

iCitric acid is a natural substance, which looks like white small grains of sugar. It is normally used in food industry and can be purchased in drugstores, wine shops or chemist's shops.

-Pour the citic acid and water solution into the water tank drawer, as explained in chapter 5, page 8.

-Fit the connector "B" to one of the edges of the exhaust-pipe, then insert the connector "B" into the steam injector (Figure 18, letter "D"). Place the free pipe edge in a vessel, to collect the limestone residues.

-Let the citric acid and water solution stay into the water tank for about 60 minutes, with the oven cooled down.

-After 60 minutes, switch on the oven by turning the function control knob on the "STEAM

COOKING" function (symbol:) and set the thermostat knob on 140° C.

-After about 20-25 minutes, turn the knobs off.

-Allow the oven to cool down, then drain the water tank following the procedure previuosly explained.

-When the procedure is carried out, rinse the water tank by pouring water into the tank drawer and letting the water flow out through the exhaust pipe, until you see clear water without limestone residues coming out.

While carrying out this procedure, a lemon flavour will be smelt in the room.

If you foresee not to use the steam oven for 2-3 weeks, we recommend to drain the water tank.

Cleaning the exhaust pipe

When a cleaning procedure has been cariied out, carefully wash the exhaust pipe in warm soapy water. Don't use acids, spray cleaners or abrasives to clean the exhaust pipe and connectors, this could damage them.

Using different water types

If you use bottled mineral water or water with low limestone content, the need of cleaning the water tank will be reduced (e.g., every 150-200 cookings). If a water conditioner or a water softener has been installed in your house, then the main water supply of your house can be normally used.

i	Using hard waters (that is, waters with high
	limestone content) will make the necessity
	of cleaning procedures more frequent, but
	this will not affect in any way the oven
	operation.
