Appendix 1: Base Dimensions

1. You are advised to make the base using angle irons, square irons, or channel steel, with a width of 50
mm and thickness of 4–5 mm.
2. The dotted lines in the figure show the area for fan lowering and bottom pipe and cable routes. Avoid
this area when preparing the base. Here the angle iron preparation is used as an example:
 If the angle iron is 50 mm wide, the base will block the holes for routing water inlet and outlet pipes.
You need to cut holes on the channel steel to avoid the blockage.
 If the angle iron is less than 50 mm wide or the 25 mm x 50 mm channel steel (shorter side
upwards) is used, the base will not block the holes for routing water inlet and outlet pipes. You do
not need to cut holes to avoid the blockage.
 If the angle iron is 72.5 mm wide or wider, the base will block the path for lowering the fan and
holes for routing cables and water inlet and outlet pipes. You need to cut holes on the channel steel
to avoid the blockage.
 For a single-door cabinet: If the angle iron is wider than 50 mm, the base will block the path for
lowering the fan and holes for routing cables and water inlet and outlet pipes. You need to cut holes
on the channel steel to avoid the blockage.
 For a double-door, triple-door, or quadruple-door cabinet: If the angle iron width ranges from 50 mm
to 72.5 mm, the base will block the holes for routing cables and water inlet and outlet pipes. You
need to cut holes on the channel steel to avoid the blockage.
3. The holes for bolts securing base and cabinet are 37.5 mm and 50 mm away from the sides. If you
cannot directly drill holes on the base for welding nuts, weld the nuts onto L-shaped components or
components with other shapes, and then secure the components to the base.
4. Attach shock absorption bars (EPDM rubber, 5 mm thick) to the base top.
