NOTE!
When mounting the evaporative cooler, it is important that it is
level to ensure proper operation and water drainage.
Installation - Evaporative Module (Optional)
Installation
Step 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.
Step 2 Apply Sealant
Apply an appropriate sealant around the airstream
opening to create an air tight seal.
Step 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.
Step 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.
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.
