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.
