1. Tap Shutdown on the LCD home screen.
2. Turn off all switches on the smart cooling product.
3. If the smart cooling product will not be used over a long time, drain the water in the heat
exchanger or take antifreeze measures to avoid frost cracks.

Appendix 1: Precautions Against Adding Glycol

For details about adding glycol, refer to the
Smart Cooling Product User Manual
To prevent glycol solution from corroding pipes and the heat exchanging coil, corrosion inhibitor
should be mixed into the glycol solution. For details about the mixing schemes, consult glycol
experts.

Appendix 2: 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 or triple-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. Control the welding errors during the welding; otherwise, the base may be unusable.
