• Installing Floor Stand
Determine the installation position according to the requirements of
Section 2.2.2
, and fix the floor stand onto
the selected mounting position. The floor stand shall be fixed to the ground through expansion bolts or spot
welding, and the floor stand shall be calibrated by horizontal ruler before it is fixed. Ensure the floor stand
should be lifted enough to make the top surface of the unit absolutely horizontal. While designing and installing
the downflow unit which requires lowering of EC fan, we must consider the proper gap distance and the base
strength of the floor stand.
• Damping Treatment
Place a layer of rubber cushion on the top, side of the floor stand, and on the bottom of the steel plate
respectively to avoid transmission of vibration during operation of the unit. Refer
for more details.
