STAINLESS STEEL CARE AND CLEANING

To prevent discoloration or rust on stainless

steel several important steps need to be taken.

Stainless steel contains 70-80% iron which

will rust. It also contains 12-30% chromium

which forms an invisible passive film over the

steels surface which acts as a shield against

corrosion. As long as the protective layer is

intact, the metal will not corrode. If the film is

broken or contaminated, outside elements can

begin to breakdown the steel and begin to form

rust or discoloration.

Proper cleaning of stainless steel requires soft

cloths or plastic scouring pads.

CAUTION: Never use steel pads, wire

brushes or scrapers.

Cleaning solutions need to be alkaline based or

non-chloride cleaners. Any cleaner containing

chlorides will damage the protective film of the

stainless steel. Chlorides are also commonly found

in hard water, salts and household and industrial

cleaners. If cleaners containing chlorides are used,

be sure to rinse repeatedly and dry thoroughly

upon completion.

Routine cleaning of stainless steel can be done

with soap and water. Extreme stains or grease

should be cleaned with a non-abrasive cleaner and

plastic scrub pad. It is always good to rub with the

grain of the steel. There are also stainless steel

cleaners available which can restore and preserve

the finish of the steels protective layer.

Early signs of stainless steel breakdown can

consist of small pits and cracks. If this has

begun, clean thoroughly and start to apply stainless

steel cleaners in attempt to restore the passivity

of the steel.

Cleaning the Condenser Coil

The condenser coil is located behind the filter

panel and is accessed through the front of the

unit (See Figure 3). The condenser coil requires

regular cleaning and is recommended every 60

days. However, in some instances you may find

that there is a large amount of debris, dust or

grease that has accumulated prior to the 60 day

time frame. In these cases the condenser coil

should be cleaned every 30 days.
