Floor Stands
Install the optional floor stand directly on the sub-floor,
ensuring the side with the "FRONT" label is facing the
same direction as the front of the precision A/C unit. Refer
to the floor stand assembly drawing for the dimensions
required to cut the raised floor. The floor stand is designed
with adjustable legs, allowing for leveling and overall
height adjustment. Refer to the floor stand assembly
drawing for minimum and maximum height adjustments.
Adjust the height of the floor stand as described in the
sections that follow. Once it is level and even with the
raised floor, lock all the feet in place. Place the A/C unit on
top of the stand.
