3. Check that all electronic equipment dust filters are cleaned. It is recommended that this be done on a weekly
basis initially due to excessive dust and dirt present at that stage. Over a period of time, the maintenance
interval may be increased depending on site environment.

cleaning liquids by cleaners is recommended, especially in areas where covers to equipment are not fitted;
particularly at floor level i.e., around TGGC.
