The water supply connected to this steamer should contain no more than 2.0 grains of hardness per gallon with pH from
any steam generating equipment.
Untreated water contains scale producing minerals which can precipitate onto the surfaces in the boiler. Due to the
temperatures in the boiler, the minerals can bake onto the surfaces and components. This can result in early component
failure and reduced product life.
Mineral scale on components causes several problems:
hot spots on the heating elements and result in premature failure.

the element is not adequately covered by water.

The steamer is equipped with a cold water condenser in the rear of the cooking chamber which helps to condense the
steam prior to discharge into the drain. The steamer freely vents itself by the negative pressure created by the condensate
water drainage. This negative pressure prevents steam leakage around the door gasket and helps draw the steam
