If the stainless steel does become stained, corroded or rusted, the iron deposits left on the surface
can be removed by neutralizing them with the passivation process. This process uses an acid to
neutralize the “free iron” deposits left on the steel where there has been deprivation of oxygen. This
stops the spread of the corrosion or rust. It will not return the stainless steel to its original finish.
7.2 Caring for and cleaning of coated surfaces
All the coated surfaces of these cabinets are powder coated. Powder coating is a method of applying
a dry powder to electro-statically charged metal, then baked in an oven where the dry powder
molecules are melted and fused together. This is by far the most durable finish available today and,
if cared for properly, will last for many years. The coated surfaces should be cleaned with a neutral
detergent and rinsed twice with clean distilled water, then dried thoroughly with a clean soft cloth.
Cleaning or disinfecting coated surfaces without rinsing with clean distilled water and drying
thoroughly will result in smearing, streaking and dulling of the coated surfaces. Never use abrasive
cleaners, scouring pads or steel wool. If the coated surfaces do become dull, streaked, smeared or
marred in some other way, there is no known method to restore the finish.
7.3 Disinfection of working chamber
1. Remove all samples from the working chamber and store them properly.
2. Remove accessories from the cabinet and disinfect them using the disinfection procedure
recommended by the manufacturer of the accessory.
3. Clean all the working chambers surfaces with disinfectant. Do not use sharp objects or fluid
on the laminator.
7.4 Rinsing of working chamber
After disinfection of the working chamber, the working chamber must be rinsed properly:
1. Rinse all surfaces of the working chamber twice with clean distilled water.
2. Dry all working chamber surfaces completely.
7.5 UV Disinfection after cleaning the working chamber
UV disinfection can be performed by using the optional factory installed UV light.
To start the UV disinfection procedure:
1. Close the front window.
2. Press the yellow button (5). The pre-programmed UV settings will be performed.
To interrupt or cancel the UV disinfection procedure, just press the yellow button (5) again.
7.6 Microbiological decontamination
Microbiological decontamination is required before accessing any area of the cabinet, which can
potentially be contaminated. Typically it is required before maintenance work and change of HEPA
filter. The control system can handle decontamination using hydrogen peroxide and formalin. All
national and local rules and regulations must be strictly observed during this process.
