Installation of Evaporative Cooling Module (optional)

NOTE

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

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.

2. Apply Sealant

Apply an appropriate sealant around the airstream opening to create an air tight seal.

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.

Placing Evaporative Module

NOTE

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

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

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

Installation of Venting for Outdoor Units

1. Follow Guidelines

All of the following guidelines must be followed when installing the unit.

Warning

Do not install units in locations where flue products can be drawn into adjacent building openings such as windows, fresh air intakes, etc. Distance from vent terminal to adjacent public walkways, adjacent buildings, operable windows, and building openings shall conform with the local codes. In the absence of local codes, installation shall conform with the National Fuel Gas Code, ANSI Z223.1, or the CAN/ CGA B-149 Installation Codes.

Warning

The following guidelines must be followed for all outdoor units:

1.Building materials that will be affected by flue gases should be protected.

2.Maintain minimum horizontal clearance of 4 feet from electric meters, gas meters, regulators, and relief equipment. In Canada, the minimum clearance is 6 feet.

3.The combustion blower discharge on outdoor units must be located a minimum of 42 inches from any combustible materials.

4.Do not modify or obstruct the combustion air inlet cover or the combustion blower weatherhood.

5.Do not add vents other than those supplied by the manufacturer.

6.During the winter, keep the unit clear of snow to prevent any blockage of the combustion venting.

2.Install Stack (Optional)

Clearance may require an exhaust stack. Install an exhaust stack as needed to the exhaust connection on the unit. Install a vent terminal on the exhaust pipe.
