The structure and coil of your fluid cooler consists primarily of
galvanized steel, therefore your water treatment program must be
compatiblewithzinc.Inworkingwithyourwatertreatmentsupplier,
it is important that you recognize the potential effects on zinc of the
specific treatment program you choose.
Coil Louver Removal
The coil inlet louvers are comprised of a series of PVC pack assemblies,
oriented to push water back into the fluid cooler. They are packed tightly to
ensure no water escapes from the air inlet.

tection is not used. Always wear gloves and sleeves when handling
louverpacks.
To remove the louvers, place both hands on the louver face and push up,
this will indicate where one assembly stops and another starts. Push a single
louver section up until it hits the top of the metal retaining channel (1). Pull the
bottom side of the louver out away from the fluid cooler and remove the louver
(2). Repeat this procedure for other packs to gain necessary access.
Proper louver pack replacement is essential to operation. Incorrect installation
may result in excessive drift rates and fan inefficiency! To ensure packs are
reinstalled in the correct orientation, it is recommended that one pack is left
in its original location inside the fluid cooler as a reminder of pack orientation.
Replace packs in the reverse procedure explained for removal. Place packs
in the tower in the order they were removed. Packs should nest tightly with
each other, leaving a level surface with no gaps.
