Evaporative Cooling
Evaporative cooling uses the principle of evaporation to lower the air temperature. Hot, dry air is passed through wetted fi lters and is converted to refreshingly cooled air. Essick Coolers make the best use of the evaporative process
by controlling the fl ow of water, spreading the water evenly over the fi lters, and keeping a steady stream of cooled air
entering your home. It is exhausted out open windows or doors, carrying heat, smoke and odors along with it. Essick
evaporative coolers are up to 80% less costly to operate than refrigerated air conditioners.
Cautions: To prevent harm to yourself and others, and to avoid damage to your cooler, PLEASE follow these guidelines.
When Installing When Operating When Servicing
Make sure that unit is installed on a sound
structure that will support the full operating weight of the cooler. See page 4.
Before attempting to hang the cooler in
the window, remove the louver to reduce
weight.
Do Not connect power to cooler before installation is complete.
Make sure that circuit cooler is plugged
into is equipped with a (slow blow) breaker
large enough to support the full amperage
of the cooler
To reduce the risk of fi re or electrical
shock, DO NOT use this fan with any
Solid-state speed control device.
This cooler is equipped with an automatic
thermally protected motor. If it shuts off
on its own for any reason, it can restart
without warning.
Always Unplug the cooler before attempting service of any kind.
Be sure to disconnect nit from power
source before servicing. If not, it can be
turned on from inside the house and start
unexpectedly.
If the motor shuts off because of thermal
overload, check into the problem immediately. If allowed to continue, permanent
damage will occur.
MOUNTING
To install this cooler, the following tools are required:
• Adjustable wrenches
• Screwdrivers
• Electric drill
• 3/16” drill bit
• Level
1. Cut the Side Sealer Channels so that two of them will span the window
when butted together. Place two of the channels on the bottom duct fl ange
as shown.
2. Place the cooler in the center of the window with the bottom duct fl ange
resting against the sill.
3. Pull out the Spacer-Rods so as to allow the Rubber Feet to rest against the
side of the house. Tighten the Adjustment Screws.
4. Lower the window to rest on top of the duct behind the top duct fl ange.
5. Fasten a stop above the inside window sash to prevent the window from
being raised. Raising the window may cause the cooler to fall.
6. Adjust the Spacer-Rods to level the cooler. This will ensure proper water
fl ow to the pads.
7. Install the Chain Supports (Not Included).
a. Drill pilot holes in the window frame, 3 feet above the top of the duct
and the width of the cooler apart. Install the Screw-Hooks in these pilot
holes to the full depth of the thread.
b. Hook one end of each Chain over each Screw-Hook.
c. Place S-Hooks in the holes at the top rear of the cooler.
d. Place the opposite end of the S-Hooks in the free end of each Chain.
Make sure the chains are taut, but not so tight they pull the bottom of the
cooler away from the wall.

8. Install the Side Sealer Panels. These panels are the correct height, but need to be
trimmed to fi t the width of our window. Trim the panels so that they reach from the
window frame to the side of the duct. Slide the panels in the channels you placed on
the bottom duct fl ange. Install the remaining Side-Sealer Channels over the top duct
fl ange and the Side-Sealer Panels.
INSTALL OVERFLOW AND DRAIN
1. Slide the Rubber Washer over the Drain Bushing and push through the hole in the
bottom of the cooler from the top side.
2. Secure the Drain Bushing from beneath the pan with the Lock Nut. Make sure the
Rubber Washer does not twist while tightening, which could cause it to leak. NO
NOT OVERTIGHTEN.
3. Thread the Overfl ow Tube into the Drain Bushing and HAND TIGHTEN.
4. If leakage occurs after Reservoir is full retighten the Overfl ow Pipe until leaking
stops. A small amount of silicone caulk may be used if necessary.

FLOAT VALVE INSTALLATION
1. Place the threaded portion of the Float Valve through the hole provided in the
Float Bracket (inside unit) as shown.
2. Slip the Fiber Washer over the threaded portion of the fl oat and secure with the
Ring Nut. Be sure the Float does not turn while you are tightening the nut.
WATER LINE CONNECTION
1. Find the closest outside water faucet, and install a Water Connection Kit (not
included with cooler) as shown. If an exterior faucet is not available, locate the
closest cold water pipe and install a saddle valve assembly.
2. Route tubing into cooler. Place Compression Nut and Ferrule over end of tubing. Insert the tubing into fl oat valve and tighten Compression Nut to
secure.
NOTE: Over tightening a compression fi tting will cause that fi tting to leak.
It is best to secure the connections, turn on the water, and then snug the
fi tting until leaking stops.
ADJUSTING WATER LEVEL AND FLOAT VALVE
1. To adjust water level, bend the fl oat valve rod.
2. Check all water connections for leaks.
3. Make sure the Float Valve cuts off completely when the desired water
level has been reached (1/2” to 3/4” below top of Overfl ow Tube). If the
fl oat does not stop the water completely, the water level will rise and run
out the Overfl ow Tube.
4. Double check the Overfl ow Tube for leaks.
START UP
1. Plug in the electrical cord to a standard grounded receptacle. Be sure the
circuit breaker protecting the receptacle is of suffi cient size.
2. Open windows in rooms where you want cooling to be directed.
3. Turn the cooler to the High Fan position. Observe the amount of air being
delivered. Note: On cool nights (or days) or when the humidity level is high,
the fan positions may be used for ventilation purposes.
4. Turn the cooler to the Low Fan position. This should signifi cantly reduce the
amount of air being delivered.
5. Turn the cooler to the Pump Only position. The pump should run and not
the fan. Check to see that water is fl owing from all three Water Trays.
6. Turn the cooler to the High Cool position. Check to see that all three Pads
are wetting evenly with no dry patches. The Pads may take up to 20 minutes to wet fully. If the Pads have dry patches, you can adjust the level of
each Water Tray by screws on each end.
7. Adjust window openings to achieve desired cooling level.

MAINTENANCE
1. Once a month during cooling season, inspect your cooler for leaks, blocked water lines and excessive residue build-up on
the pads.
2. At the end of the season, drain the reservoir. Remove the drainpipe and let water and dirt pass through the drain fi tting.
3. Lime build-up can occur in the water reservoir and on louvers. Clean this off at least once per season. If any rust or bare
metal spots occur on the cabinet or louver, the metal should be sanded, primed and painted with a good quality paint.
4. If freezing weather occurs in your area, it is best to shut off the water supply at the source and drain the supply line to the
cooler.
5. A cooler cover is recommended to prevent rain and weather from damaging your cooler.
6. To prevent the Shaft from rusting, coat with a wax based lubricant. Allow lubricant to dry completely and all fumes to disperse before turning on the cooler.
DO NOT GET WATER ON MOTOR OR PUMP MOTOR
NOTE: Depending on the mineral content of the water or the amount of air borne dust in your are, you may need
to replace fi lter pads during the season.
It is best to replace fi lter pads again at the end of the season. Old fi lter pads soak up lime and salts, which can rust
the louvers and the cabinet during the winter months.
TO REPLACE PADS
1. Remove louver (U) from cooler.
2. Unhook pad holders (V) at the sides of the louver and above and below side
pads inside cooler.
3. Remove old pads (W) and discard.
4. Tuck in rear pad to make sure hot air can not by-pass fi lter .
5. Place pad holders over new pad and hook into place.
6. For the side pads, center pad over louver openings in cabinet, hook pad
holder below pad, tilt into place and hook at top.
