GENERALINTRODUCTION

Every Stero product is built with the highestquality components and innovative featuresthat have established Stero’s reputation asthe food service industry’s warewashingauthority.

Stero Rack Conveyor washers move rackeddishes by a pawl. Pawl action uses a singlebar to pull the racks through the dishwasher.The dish rack is conveyed through a spraypattern directed from upper and lowerstationary spray arms at a prescribed GPMflow rate. After the rack has passed throughthe wash spray, it moves on to activate thefresh-water final rinse.

Automatic warewashers contain heaters thatmaintain the proper water temperature in thedishwasher tanks. These heaters useelectricity, steam or gas. As a general rule,heaters maintain a tank temperature of 160ºF(71ºC) to ensure sanitation. Hot watersanitizing warewashing dishwashers use abooster heater to raise the incoming, generalpurpose hot water to at least 180ºF (82ºC) forthe final sanitizing rinse.

The NSF requires an established amount ofheat content to ensure sanitation. The waterpressure for this cycle must be 20 PSI.

LOCATION OF DATA PLATE

The data plate (Figure 1) is located either onthe front or on the side of the Main ElectricalControl Panel. This data plate containsimportant information, including thedishwasher model and serial number.

Never use acid–based or chloride–containing cleaning solutions, which will breakdown the protective film!

Never rub in a circular motion!

Never leave any food products orsalt on the surface. Many foods are acidic.Salt contains chloride!

For routine cleaning, use warm water, mildsoap or detergent and a sponge or soft cloth.

For heavy–duty cleaning, use warm water, adegreaser and a plastic, stainless steel orScotch–Brite pad.

• Always rinse thoroughly.

• Always rub gently in the direction of thesteel grain.

Preserving & Restoring

Special stainless steel polishing cleaners canpreserve and restore the protective film.

Preserve the life of stainless steel with aregular application of a high quality stainlesssteel polishing cleaner as a final step to dailycleaning.

If signs of breakdown appear, restore thestainless steel surface. First, thoroughly clean,rinse and dry the surface. Then, on a dailybasis, apply a high–quality stainless steelpol ish according to manufacturer’sinstructions.
