Ground Mounting 1
1. Place the cardboard flat on the floor, mark the location of the holes with a marker, then remove the cardboard. Drill
the holes by using an electric drill (18mm in diameter, 80-90mm in depth). Disassemble the M12*80 expansion screws
and put the screws sleeves into the holes.
Note: The ground should be flat and no inclination.
2.
Install the cabinet to the designated location
By using a crane:
As shown in the following figure, lift the cabinet, align the holes at the cabinet bottom with the drilled holes, and place it onto the floor.
A force greater than 2t is required to move this device, the height between the sling and the top surface must be greater than or equal
to 1.5 meter.
By using a forklift:
As shown in the following figure, move the cabinet, align the holes at the cabinet bottom with the drilled holes, and place it onto the
floor.

To choose a right forklift, refer to the following requirements:
- Load capacity must be greater than 2 tons.
- The length of the metal forks must be greater than 1.2 meter. Use fork extensions if needed.
- The forks can slide under the cabinet bottom without damaging the cabinet.
To use the forklift, make sure that:
- The forks should be extend out of the cabinet.
- Adjust the distance between the two forks to ensure load stability.
