Cleaning the BSC

Clean the work surface and walls with appropriate disinfectant agent and soap water afterward

Clean the sash window using an appropriate disinfectant agent and glass cleaner afterward

Use a damp cloth to clean the exterior surface of the BSC, particularly on the front and top in order to
remove dust that accumulated there

Use clean water to finish the cleaning and wash away any residue of disinfectant agent, soap water
and glass cleaner

For removing stubborn stains or spots on the stainless steel surface, make use of MEK (Methyl-Ethyl-
Ketone). In such cases, make sure that you wash the steel surface immediately afterwards with clean
water and some liquid detergent. Use a polyurethane cloth or sponge for washing. Regularly cleaning
the stainless steel surface can help you retain the attractive factory finish.
Test the audible and visual alarm
The simplest method by far would be to move the sash until the glass window is no longer in the sash ready or
UV mode position.
Check the cabinet’s functionality

Check the BSC’s mechanical functionality; ex: sash window – lubricate if necessary

Check the BSC’s electrical functionality; ex: fluorescent lamp – replace if necessary

Check the BSC for any defect, repair immediately
Re-certification
All BSC must be re-certified annually by a certified engineer. See test report for recertification procedure.
