ATTENTION INSTALLING PERSONNEL

As a professional installer, you have an obligation to know 

the product better than the customer. This includes all 

safety precautions and related items.

Prior to actual installation, thoroughly familiarize yourself 

with this Instruction Manual. Pay special attention to all 

safety warnings. Often during installation or repair, it is 

possible to place yourself in a position which is more 

hazardous than when the unit is in operation.

Remember, it is your responsibility to install the product 

safely and to know it well enough to be able to instruct a 

customer in its safe use.

Safety is a matter of common sense...a matter of thinking 

before acting. Most dealers have a list of specific good 

safety practices...follow them.

The precautions listed in this Installation Manual are 

intended as supplemental to existing practices. However, 

if there is a direct conflict between existing practices and 

the content of this manual, the precautions listed here take 

precedence.

DESCRIPTION

The horizontal prop power exhaust kits are used in 

conjunction with the model numbers listed at the top of 

this installation instruction. These kits are not applicable to 

vertical applications. See Table 1 for package usage.

The power exhaust kit includes (1 or 2) 300mm EBM prop-

type fan(s), mounted in power exhaust housing. Wiring 

harnesses are provided to connect the power exhaust to 

the economizer for low voltage, and to the unit single point 

connection for high voltage.

The power exhaust housing is constructed of pre-painted 

steel to match color of rooftop unit. For 7½-12½ Ton 

applications, the power exhaust replaces the barometric 

relief hood on the field supplied return air duct, and mounts 
near the economizer.
