7. Always Disconnect Power before performing any maintenance.
Operation
T o eliminate delivery of hot air when starting cooler , Start the pump
without the blower for the first few minutes, then turn on the blower
motor.
These coolers may be used without water for ventilation purposes.
When outside air is cool (for example, at night) or when humidity is
high the water pump can be turned off.

Installation
CAUTION: Make sure that the mounting surface is strong
enough to support the operating weight of the cooler when in
use. (For operating weight, see Specification Table.)
CAUTION: Never start cooler until installation is complete
and unit has been tested for rigidity.
CAUTION: This unit must be installed at a height of 10 feet
or greater from the floor.
Electrical Installation
NOTE: Local building code regulations must be observed.
WARNING: Disconnect all electrical service that will be
used for this unit before you begin the installation.
• Connect electrical. Cooler must be connected to the proper line
current, voltage and cycle, as indicated on the decal located at the
electrical service entrance. Connecting improper voltage to motor
will void motor warranty. See the wiring diagrams (figures 8 & 9)
on page 3 for wiring electrical connections.
NOTE: A separate 120 Volt, 60 Hz, 1 phase pump electrical circuit
is required to maintain the integrity of the GFCI pump protection
and to maintain the U.L. Listing of the evaporative cooler.
• Wire gage. The horse power, voltage, cycle, phase, current, and
length of wire required from switch to motor will determine the
gauge of wire to be used.
• Switches. Larger horsepower and three phase applications require
switches (not supplied) of proper current capacity and should be
installed by a competent electrician.
• Power Supply box. The
power supply box is located in the upper inside
of the divider channel.
Remove the cover to access wiring. (Fig. 1).
Connect wiring in box to
power supply wiring as
per wiring diagrams.
WARNING: Make sure that cooler cabinet is properly
grounded to a suitable ground connection for maximum safety.
Water Connection
• Pumps. Plug the pumps into the pump receptacles. There are
metal cord retaining clips on the corner post and motor cross braces
for retaining the pump cords.
CAUTION: The pump cord must be secured to prevent it
from dropping into water reservoirs or contacting moving components.
• Install overflow assembly. Remove
nut and place nipple through the hole
in the pan, with the rubber washer
between the pan and the head of the
drain nipple (Fig. 2). Screw on nut
and draw up tight against bottom of
pan. Insert overflow pipe in nipple
to retain water. Overflow pipe may
be removed to drain pan when necessary. A garden hose may be screwed on the drain nipple to drain
water away from your unit.

• Connect water supply line. A water supply line should be run to
the cooler to supply an adequate amount of cold water to the unit.
The amount of water each cooler uses will depend on the weather
conditions in your area and the size of your unit. The hotter and
dryer your climate and the higher the capacity of your unit, the
more water will evaporate. For example: An FAD248 unit with a
2 hp motor will use approximately 85 gallons per hour in a hot and
dry climate like Las V egas on a 105°F day with 10% humidity . The
same unit in a cooler climate with 95°F and 20% humidity would
use approximately 63 gph.
NOTE: Do not connect the water supply line to any soft water
applications.
• Install float valve and fill pan. Refer to Fig. 3. Remove items 1,
2, 3, and 4. Insert float body (5) through hole in back post panel as
shown. Install washer (1) and nut
(2). Tighten to keep float from
turning. Place nut (4) and ferrule
(3) on water supply line. Con-

until it snaps into place.
• Bleed-Off. Use of the bleed-off kit is recommended to prevent
scale build up by bleeding off small amounts of circulating water
during operation. Do not add any type of water treatment chemicals to the water.
Maintenance
WARNING: Before doing any maintenance be sure to dis-
connect from power source. This is for your safety.
Spring Start-Up
• Check belt tension. A 3 lb. force
should deflect the belt 3/4 inches
(see Fig. 4). Readjust belt if
needed.
To adjust belt, loosen the two
hinge nuts and the locking nut on
the adjusting bolt as shown in
figure 5. Loosen or tighten the
adjustment nut until the belt is
at the right tension. Lock the
motor plate in place by tightening the locking nut and then
tighten the 2 hinge nuts.
• Grease bearings. The shaft
bearings in this unit should be
greased once a year with a good
grade of ball bearing grease.
• Clean pads. A clean pad is more absorbent, efficient and will give
more cool air. Annually , or when required, using a garden hose with
nozzle, back wash to clean out the openings, then clean off the inlet
face any scale or other obstruction to the passages. Slight scraping
may be required to remove hardened scale.

• Pad replacement. The pads should be replaced after 5 years or
before if necessary. To change pads, remove top access panel,
remove grill, and disconnect water delivery tube. Remove water
distributor holder and lift out media sections. Replace with the
same type media. You can purchase them from your dealer.
IMPORTANT: In order to get the best performance from your
cooling pads, they must be installed properly. If you have purchased a pad with two equal angles, the following instructions can
be disregarded. Pads must always be installed with the steeper
flute angle sloping down towards the air entering side (Fig. 6). The
reason is simple. The
steeper angle puts more
water on the hot, dry, dirty
side of the pad where it is
needed most. It also coun-

teracts the tendency of the
air to push the water toward the back of the pad.

• Cleaning pumps. Cleaning the
pumps is necessary once a year at
start-up. For your safety, discon-
Remove
nect from power source and unplug
pump. Remove the pump from
the mount bracket. Remove the
base of the pump (Fig. 7). Clean
the pump and turn the impeller to
ensure free operation. Remove the
Fig. 7
pump spout and check for any blockage. After cleaning, reinstall
the base onto the pump. Reattach the pump to the mount in the
cooler to ensure that the pump will not overturn. Do not forget to
replace the spout and water delivery tube onto the pump outlet.
NOTE: The pump has automatic reset thermal protection. The
pump motor will stop if it overheats. The pump will operate
normal again after obstruction is cleared.
• Check bleed-off valve to be sure it is not clogged.
Winter Shut Down
• Drain water. Always drain all of the water out of the cooler and
water supply line when not in use for prolonged periods, and particularly at the end of the season. Keep the water line disconnected
from both the unit and water supply so that water will not seep
into the line and freeze.
• Disconnect from power supply when not in use for extended
periods of time.
• Cover unit. To protect the life of the finish, a cover for the unit is
suggested in extended periods of non use.
By following the operating, installation, and maintenance suggestions
as outlined, you can get many years of efficient and satisfactory
service from your cooler. In the event additional information is desired, your dealer will be more than glad to assist you in every possible
way.
