loosen the tap screws securing the frame in place and pull the frame away
from the fluid cooler. Louver frames are not always the same size; if more than
one louver frame is removed, the original location should be noted.
Collection basin floor has uneven surfaces and has the potential to
be slippery. Care should be taken if entering the basin.
Louver edges can be very sharp and could cut skin if proper protec-
tion is not used. Always wear gloves and sleeves when handling
louver packs.

Access Doors:

To allow access to the mechanical system, eliminators, water distribution sys-
tem, coil surface and fill media, multiple access doors are provided in various
locations of the fluid cooler. To open, lift up on the handles to slide free and
remove. To close, position door over frame and slide downward until door
seats in trough. Replace doors prior to operation.

Heat Transfer Fill Media Removal and Replacement:

Fill edges can be very sharp and can cut skin if proper protection is
not used. Always wear gloves and sleeves when handling elimina-
tor packs.
PVC heat transfer media (fill) is used in the LW fluid cooler to enhance the
evaporative cooling process. The fill is assembled into packs supported by
beams above the air inlet, and may be removed for inspection, cleaning or
replacement.
To remove the fill, open the lower access door(s) and locate a fill pack with a
paint-marked end. Marked packs are smaller than the remainder of the packs,
and one is installed near each lower access door. Pull the marked pack out
through the access door, and then the rest of the packs can be removed. Pay
close attention to the orientation and placement. Replace packs in the reverse
order in which they were removed.
