Clearance dimensions provided in
Figure 10 on page 30 and Table 2 on
page 30 are necessary to maintain good
airflow and ensure correct unit opera -
tion. It is also necessary to consider ac-
cess requirements for safe operation and
maintenance of the unit and power and
control panels. Local health and safety
regulations, or practical considerations
for service replacement of large compo-
nents, may require larger clearances than
those recommended.
