the equipment room.
In regions with high humidity, use dehumidifiers.
Use dust-free materials for the floor, walls, and ceilings.
Screen exterior doors and windows. The external windows of the equipment room
should be sealed for anti-dust purposes.
Clean the equipment room and air filters on the devices once every three months.
