Slab
1. Pour Concrete Slab
Pour the concrete slab.
Make the slab one foot
larger than the unit on all
sides. The slab must be
capable of supporting
the weight of the unit. Proper
subgrade preparation must be
completed under the slab. 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 position the unit on the
concrete slab. The use of
all lifting lugs and a set of
spreader bars is mandatory
when lifting the unit. It is
recommended that any
shipped loose modules be
installed after the base unit.
The shipped loose modules must be fastened together.
Fasten the cover seams and vertical panels on each
module using sheet metal screws. Using an appropriate
sealant, seal the seam(s) between each shipped loose
module and the weatherhood.
Some shipped loose modules will require field-provided
shims for proper alignment with the base unit.
If an optional evaporative cooling module is included,
reference
Installation, Optional Component Mounting,
Evaporative Cooling Module
section in this Installation,
Operation and Maintenance Manual for more
information.
Fasten the unit to the slab using appropriate methods.
The installer is responsible for determining appropriate
fastening methods to ensure compliance with all
applicable codes.
3. Attach Ductwork
Use an appropriate sealant around the discharge opening
of the unit to create a weathertight seal.
Follow good duct practices for all ductwork. Install
ductwork in accordance with SMACNA and AMCA
guidelines, NFPA 96 and local codes. Reference

duct sizes.
1. Slab Construction
Recommended Size is 1 ft wider and longer than total unit size.
Recommended Material is concrete at least 4” thick.
Slab should be set level on a sufficient bed of gravel for proper drainage.
2. Install TSU Unit
Use a crane and spreader bar to prevent damage to unit. Lifting lugs
are provided as shown in illustration.
It is highly recommended that all accessory items be lifted separately
and attached after the TSU unit is in place (see page 11).
Unit may be fastened to slab through lifting lugs.

Rail
1. Install Rails
The rails must be located around the perimeter of the
base unit on all four sides. This is required to ensure
proper unit support. Model
TSU requires an additional
rail section under the
filter section to ensure
proper support of the filter
section and weatherhood.
Rails are field-supplied
by others and are not
supplied by manufacturer.
2. Install Unit
Use a crane and a set of
spreader bars hooked to
the factory lifting lugs to lift
and position the unit on the
field-supplied rail supports.
The use of all lifting lugs and
a set of spreader bars is
