Do not lift non-base units or subassemblies by attaching clevis, 
hooks, pins, bolts, etc. to casing, casing hardware, angles, tabs 

or flanges. 

See CAUTION

!

 Lift the air unit only in an upright 

position. Never lift or move a unit on its side or upside-down.

CAUTION

If you do not rig or lift the unit carefully, you could 
damage the unit, hurt yourself or others. USE CAUTION!

SUPPORT STRUCTURE INFORMATION

AcuAir

®

 systems may be shipped in two or more sections. 

These sections must be anchored to a suitable support 
structure - concrete pads, concrete piers, or structural steel, 
capable of supporting the total system operating weight plus a 

significant safety margin as determined by a qualified structural 

engineer. The weight the support structure must support and 
the anchoring requirements will vary with live loads (expected 
snow/ice buildup) seismic, and wind loading. See Figures 6 
and 7  for AcuAir unit support methods.

If the support structure is in the form of two or more parallel 
steel beams, the beams should be sized in accordance with 
standard engineering practices. The structure must be capable 
of supporting the shipping weight of the unit as provided on 
the order related document, plus any operating-duty-related 
loads such as: water or refrigerant within the cooling and 
heating coils; possible frost on the cooling coils; any applicable 

flooded refrigerant surge vessel and associated piping; snow 

loads that could accumulate on the roof; horizontal wind 
loads; etc.

It is recommended that the structure be designed for at least 
110% of the operating weight of the system distributed as 
a uniform load over the longitudinal beams, allowing for a 

maximum deflection of 1/360 of the length, not to exceed 1/2".

The support structure, whether concrete pads, concrete piers, 
or structural steel, on which the units are to be located should 
be rigid and level (shim if required).

Shims should be placed at intervals no greater than 5 feet apart 

and should not be used to compensate for significant surface 

slope. The sum total of any individual stack of shims should 
not exceed ½” and are to be used to compensate for surface 
irregularities only. On units more than 150 inches wide the 
foundation shall support not only the perimeter base channel, 
but also the midpoint of each unit split. (Reference Figure 6) 
Consult factory if housekeeping pad is not continuous.

The AcuAir unit must be secured to the Support structure. It 
is the installer’s responsibility to be sure the unit is secured 
in accordance with applicable codes.

NOTICE

Shims  may  be  used  between  the  AcuAir  unit  and  the 
supporting structure. When shims are used they should 
be spaced no more than 5 feet apart. Shim stacks should 
not exceed 1/2 inch in height.

ASSEMBLY HINT

Units must typically be SLID into final position. Applying 
grease to the support surface may make this easier.

NOTICE

Save bolts when removing lifting lugs. Bolts will be used 
for assembly of split units.
