RIGID CELLULOSE EVAPORATIVE COOLING MEDIA
REPLACEMENT INSTRUCTIONS
WARNING — DISCONNECT POWER TO YOUR EVAPORATIVE COOLER TO AVOID
ELECTRICAL SHOCKS BEFORE PERFORMING ANY SERVICE ON IT.
IMPORTANT — Cooler media MUST be installed correctly. If not, performance will diminish
(air will not be as cold as it should) and water can be pulled off of pads (getting many things wet,
including ducts, ceilings, etc.).
Your cooling media is made up of
alternating sheets having two
different angles. The 15 degree angle
slopes downward towards the inside
of the cooler. The steeper 45 degree
angle should slope downward
towards the outside of the cooler
(towards the air entering side). To
help you properly install your pads,
arrows are marked on the side of the
pad that show the “Top” and “Air
Flow” directions (see figure).
NOTE: New pads have a “start-up”
odor. To reduce this, the media
should be washed for several hours
by running the pump without any
airflow through the pads. Drain the
water pan, refill with fresh water and
start up the system. Repeat if
deemed necessary. This procedure
also helps the wetting ability of your
new pads. The odor will also
dissipate over time by installing a
purge pump or a bleed-off tee.
Replacement media may not fit as tightly into your evaporative cooler as the original pads. Using
Styrofoam panels at either end of the pad assembly can make up this difference.
