Service Access
24 in.
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.
