SAFETY CONSIDERATIONS

SAFETY NOTE

Air-handling equipment will provide safe and reliable service when operated within design specifications. The equipment should be operated and serviced only by authorized personnel who have a thorough knowledge of system operation, safety devices and emergency procedures.

Good judgement should be used in applying any manu- facturer’s instructions to avoid injury to personnel or dam- age to equipment and property.

Disconnect all power to the unit before performing mainte- nance or service. Unit may automatically start if power is not disconnected. Electrical shock and personal injury could result.

If it is necessary to remove and dispose of mercury contac- tors in electric heat section, follow all local, state, and fed- eral laws regarding disposal of equipment containing hazardous materials.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
