arm while pulling out from the header box.
When branch arms are removed, access to the interior of the spray header
box is available to clean and remove any debris or sediment. A drain nozzle
at the centerline of the header box is intended to drain water from the
system at shutdown, as well as be removed to wash out the header box if
necessary. Be sure to replace this nozzle if removed.
Reinstall the branch arms to the header, engaging them far enough to
align the bolts of the tie down strap to the spray system supports. It may
be necessary to wet the rubber grommet and pipe to facilitate assembly.
Ensure that all nozzles are aligned to the bottom of the branch arm.
Schedule of Tower Maintenance
Some procedures may require maintenance personnel to enter the tower.
Each cell has an access door for entry into the tower. All tower maintenance
can be performed from this location. An optional mechanical access platform
is designed and intended solely for personnel to gain access to the motor
and access door. Upon entering the tower, the eliminators and fill may be
used as a walking surface for tower inspection and typical maintenance.
For those instances of frequent or prolonged servicing, it is necessary to
protect the surface with plywood or planking. The fan deck and fan guard
are not designed as a walking or working surfaces. There are no mainte-
nance procedures that require access to top of the tower.
The purchaser or owner is responsible for providing a safe method
for entering or exiting the access door.
Included with this instruction packet are separate User Manuals on each
major operating component of the tower, and it is recommended that you
read them thoroughly. Where discrepancies may exist, the separate User
Manuals will take precedence. The following is recommended as a minimum
routine of scheduled maintenance:
Always shut off electrical power to the tower fan motor prior to
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.
