Schedule of Tower Maintenance
Some maintenance procedures may require maintenance personnel to enter
the tower. Each cased face of the tower has a door for access to the interior
of the tower. The NC8401 and NC8402 have a 30" wide by 33" high door.
All other models have a 30" wide by 48" high door.
The optional fan deck ladder is designed and intended solely for personnel to
gain access to the fan deck. The fan deck ladder should not be used to enter
or exit the access doors located on the cased face of the tower unless the
optional access door platform is provided.
