These bases have a durable finish to match the evaporator blower unit. They may have to be insulated for certain applications. SUSPENSION PACKAGES: These accessories can be used to suspend horizontal units from above without interfering with access to the unit. They can also be used for elevating a floor-mounted unit (either horizontal or vertical) to provide additional height for the installation of a trap at the condensate drain connection. All suspension packages can be used with vibration is

Do not use steam in hot water coils. Do not operate the supply air blower above its nominal HP rating when a unit is equipped with a steam coil accessory. Although these coils are suitable for a much higher pressure, steam above 25 psig provides too much heat that could damage the blower motor. 1. These units are equipped from the factory with a correctly sized motor starter; overload elements are not factory supplied. Note: Three elements required per unit.

Unit resistance is based on a dry evaporator coil and clean filters. 2. Available static pressure in IWG to overcome the resistance of the duct system and any accessories added to the unit. Refer to the blower motor and drive table and the accessory static resistance table for additional information. 3. Motors can be selected to operate into the service factor because they are located in the moving air stream, upstream of any heating device. units with steam or hot water coils are the only excep
