Clearance and Mounting for Indoor AHUs

It is recommended that the AHU is located in an air
-conditioned space. Some suggested installations are
shown in Figure 14 on page 26. Make sure the floor
and housekeeping pads are flat and level.
Allow sufficient space around the AHU to remove the
access panels and various parts. A minimum clearance
equal to the width of the AHU plus 6 in. must be pro-
vided on one side of the AHU to remove the coil or fan
assembly.
Concrete pads may not be as flat as they should be.
Shimming and/or grouting may be necessary. Whether
under the AHU base or curb, the AHU base needs to
be on a flat plane.
Mounting Indoor AHU
Install the AHUs to provide enough elevation for prop-
erly designed condensation traps as discussed in
Drains and Traps on page 93.
