Electrical shock, severe injury or death could occur if instructions given in this manual are not

Proper commissioning of this equipment is the responsibility of the installing contractor. It is
recommended that an air balance be completed before the unit start up by a certified air
balancing contractor to ensure that the air volume being sent downstream of the unit into the

cause injury or death, damage to the equipment, property damage, system operational
problems, or be a cause of poor indoor air quality. Moisture carries over can also result from
improper air flow.
