Pre-Startup Checklist

Know the system. Read this manual carefully. Make use of its instructions and
explanations. The know how of safe, continuous, satisfactory, trouble-free
operation depends primarily on the degree of your understanding of the system
and of your willingness to keep all parts in proper operating condition.

Check line voltage. This must correspond to nameplate requirements of motors
and controls. A wrong voltage can result in serious damage. Refer to the
section on power connections in the INTRODUCTION of this manual.

Check fresh air & exhaust dampers (Non-atmosphere models only). Do not be
careless about restrictions in and around the fresh air and exhaust openings and
stacks. Under no condition, permit them to become so filled with dirt that they
reduce airflow.

vent (fresh air models). After desired
temperature is reached, vent may be
