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.
The purchaser or owner is responsible for providing a safe method
for entering or exiting the access door. Use of the fan deck ladder
to enter or exit the access doors may result in a fall.
Included with this instruction packet are separate Service Manuals on each
major operating component of the tower, and it is recommended that you
read them thoroughly. Where discrepancies may exist, the separate Service
Manuals will take precedence.

performing any inspections that may involve physical contact with
the mechanical or electrical equipment in or on the tower. Lock out
and tag out any electrical switches to prevent others from turning
the power back on. Service personnel must wear proper personal
protective clothing and equipment.

rial growth should be reported to your water treatment expert for immediate
attention.
