• The formula for calculating airflow using temperature rise and heating BTUH for units
with electric resistance heat is:
Heating BTUH
CFM =
1.08 x Temp. Rise
12.4 C LCUL TING CORRECTION F CTOR
• For correction of electric heat output (kW or BTUH) or temperature rise at voltages
other than rated voltage multiply by the following correction factor:

For continuing high performance, and to minimize possible equipment failure, it is essen-
tial that periodic maintenance be performed on this equipment. Consult your local dealer
as to the proper frequency of maintenance and the availability of a maintenance contract
IMPORTANT: Before performing any service or maintenance procedures, see the
"Safety Information" section at the front of this manual.
W RNING
Units with circuit breaker(s) meet requirements as a service disconnect switch,
however, if access is required to the line side (covered) of the circuit breaker,
this side of the breaker(s) will be energized with the breaker(s) de-energized.
Contact with the line side can cause electrical shock resulting in personal
injury or death.
