It may also be necessary to remove an entire branch arm from the spray sys-
tem. Each arm is held in place with a retention strap bolted to the branch arm
supports. Remove the bolts attaching the strap to the support and pull sharply
on the branch arm to disengage from the header box. It may be necessary to
rotate the branch 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 neces-
sary 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 maintenance 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 ma-
jor 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:
