SAFETY CONSIDERATIONS

SAFETY NOTE
Air-conditioning equipment will provide safe and reli-
able 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
manufacturer's instructions to avoid injury to personnel or
damage 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
federal laws regarding disposal of equipment containing
hazardous materials.
