appropriate means complying with OSHA or other applicable safety standards of governmental authorities.
Stepping on or placing weight on an eliminator can result in physical injury and/or equipment damage. After
ensuring that the fan and pump motors are locked and tagged out, lift and remove eliminators as necessary to
perform recommended maintenance and inspections. If access to the top of the coil is required, place a piece
of plywood at least 1/2 inch thick on top of the coil to protect the surface while performing the recommended
maintenance. When finished, carefully remove the plywood and re-install any eliminators which were removed.
eliminators in place using the retaining system.
Water is distributed through a corrosion resistant polyvinyl chloride (PVC) spray distribution system. The drift eliminators are
made of PVC, which requires no protection against rot, decay, rust, or biological attack.
The inspection procedure is as follows:
•
Shut off the fan and lock out and tag out the fan and pump motors.
•
Remove drift eliminators to allow a clear view of the spray distribution system and nozzle patterns.
•
Start the recirculating pump. Make sure the fan motor is locked out and tagged out. Check to see if the nozzles are all
spraying consistently and producing the spray pattern shown in Figure 10.
•
Clean any nozzles that are clogged. If necessary, the nozzle and rubber grommet may be removed for cleaning. If
additional cleaning is necessary, the branch may be removed for cleaning. With the BranchLok™ System, tools are not
required to remove the branches.
•
Inspect the coil surface. Any corrosion, damage, or obstructions must be corrected.
•
The coil is designed for seasonal dry operation followed by seasonal wet operation, and not for frequent cycling of the
spray pump. Frequent spray pump cycling may lead to excessive scale buildup.
With electrical heater tape, heat trace and insulate all exposed water piping, including pump piping below the overflow level
and make-up water lines.
NOTICE: Do not use steam or high-pressure water to clean PVC eliminators, fill or materials
other than steel.
