Installation – Slab Mounted Unit
1. Pour Concrete Slab
Pour the concrete slab. The slab should be one foot 
larger than the unit on all sides. 
The slab should be at 
least four inches thick 
and poured on a bed of 
gravel to ensure proper 
drainage. Allow the 
concrete slab to properly cure 
before installing the unit.
2. Install Unit
Use a crane and a set of 
spreader bars hooked 
to the factory lifting lugs 
to lift and center the unit 
on the concrete slab. 
Fasten the unit to the 
slab through the factory- 
provided lifting lugs.
NOTE
The use of all lifting lugs and a set of spreader bars in 
mandatory when lifting the unit.
NOTE
For easy installation, it is recommended that the 
weatherhood, filter section or evaporative cooler be 
installed after the base unit.
3. Attach Ductwork
Refer to the CAPS submittal for the duct size and 
location. Manufacturer recommends attaching ductwork 
using a rubber duct section at the unit to reduce 
vibration. An 
appropriate 
sealant should 
be used around 
the discharge 
opening of the 
unit to create a 
weathertight seal.
Good duct practices should be followed for all 
ductwork. Ductwork should be installed in accordance 
with SMACNA and AMCA guidelines, NFPA 96 and any 
local codes.
