CHASSIS

As-needed cleaning of the unit's exterior surfaces (Figure 24) optimizes the unit's appearance and removes particles that may enter the air system. The 52S units are built to resist corrosion. The indoor front panel and wall sleeve are created from non-metallic compounds that do not rust. Additional corrosion protection may be factory installed on the partition, control box, and out- side coil for use in highly corrosive environments. Mild detergents reduce electrostatic charges on plastic sec- tions on the grille and are good cleaners. Use such deter- gent cleaners sparingly.

Use a clean cloth or brush to gently wipe exterior sur- faces. Be careful not to push dirt or other ®bers into the unit's interior. Accessible sleeve surfaces should also be wiped clean.
