12 UNT-IOM-6
Service access is available from the front on vertical units and from
the bottom on horizontal units. Cabinet and recessed units have
removable front or bottom panels to allow access into the unit. See
Figure 3 for recommended service and operating clearances.
Units have either right or left hand piping. Reference piping locations
by facing the front of the unit (airflow discharges from the front). The
control panel is always on the end opposite the piping.
The unit has a modular fan board assembly that is easy to remove.
Also, the main drain pan is easily removable for cleaning. See the
Maintenance section beginning on page 88 for more details on
servicing.
