Modular Supply Make-Up Air Unit

Installation of Evaporative Cooling
Module (optional)

NOTE

Small evaporative coolers ship attached to the base
unit and require no additional mounting.

NOTE

The use of all lifting lugs and a set of spreader bars is
mandatory when lifting the evaporative cooling module.

NOTE

When mounting the evaporative cooler, it is important
that it is level to ensure proper operation and water
drainage.

Placing Evaporative Module

Securing Evaporative Module

1. Locate Equipment Support(s). Position equipment

support(s) on the roof (reference the CAPS submittal
for placement of equipment support(s) in relation
to the unit).
Verify that all
unit supports
are level, shim
if necessary.
Attach
equipment
support to the
roof, remove
metal cover,
ﬂash to wooden
nailer and reinstall cover.

4. Secure Cooling Module to Unit. Use self-tapping

screws to fasten the cooling module to the base
unit along the top and down both sides. Fasten at
the top through the ﬂanges. To fasten the sides,
the media must be removed. To remove the media,
ﬁrst remove the access panel on the evaporative
module and disconnect the evaporative pump(s). The
media will now slide out. With the media removed,
you can access the side fastening points inside the
evaporative module. With all the screws in place,
reinstall the media, reconnect the pumps and reinstall
the access panel.

Sealant

3. Set Evaporative Cooling Module. Use a crane

and a set of spreader bars hooked to the factory lifting
lugs to lift and center the module on the equipment
support(s). The ﬂange on the evaporative cooler should
overlap the ﬂange on the unit.

2. Apply Sealant. Apply an appropriate sealant around

the airstream opening to create an air tight seal.
