Evaporative Cooling
Evaporative cooling uses the principle of evaporation to lower the air temperature. Hot, dry air is passed through wetted
filters and is converted to refreshingly cooled air. Essick Coolers make the best use of the evaporative process by
controlling the flow of water, spreading the water evenly over the filters, 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 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.
SAFETY GUIDE LINES & CAUTIONS
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 5. Make sure that cooler circuit is equipped with a
(slow blow) breaker large enough to support the
full amperage of the cooler.
Be sure to disconnect unit from power
source before servicing. If not, it can be
turned on from inside the house and start
unexpectedly.
Before attempting to transport cooler to the roof.
Separate fan section from wet section to reduce
weight. Always plan a safe method of
transporting cooler to installation site without
damage to the cooler or injury to yourself.
To reduce the risk of fire or electrical shock, DO
NOT use this fan with any Solid-state speed
control device. Never drain water onto your roof. Water
residue could cause you to slip or may stain
your roof.
Do Not connect power to cooler before
installation is complete.
Wear gloves and protective eyewear when
installing or servicing. 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. If the motor shuts off because of thermal
overload, check into the problem
immediately. If allowed to continue,
permanent damage will occur.
Tools and supplies needed for installation
Pliers
Screwdrivers
Adjustable wrenches
Tubing cutter
5/32 hex key wrench
Level
Electric drill
Drill bits
Hammer
Duct tape
Caulk
Sheet metal screws
ECR-6 wall switch
Safety glasses
Wiring supplies – It is recommended that a licensed
electrician do all electrical work.
Ductwork – A local sheet metal shop can supply ductwork.
¼” water line
Saddle valve or faucet adapter
Roof stand (if cooler is roof mounted)
Roof flashing and pitch
Mounting
1. Prepare duct to fit model used (500 series coolers 17 ¾” square; 700 series 19 ¾” square).
2. Cut opening in wall or roof to fit duct. If wall studs or roof joists are cut, reinforce them.
3. Mount the duct in the opening. The duct will fit inside the cooler opening. The duct length from roof to bottom of cooler
should be a minimum of 4” at the closest point, so there is access to the water drain.
4. Install flashing around roof opening to prevent water entry. Use pitch to seal the seams.
5. Measure cooler and layout mounting location.
6. Mount cooler to stand or pad. Cooler must be level front to back and left to right. Note: It is best that the fan section
end of the cooler face up the roof to achieve a lower profile and allow better access to the drain.
7. Be sure to securely fasten all four corners of cooler to stand or pad.
8. Caulk duct to the cooler to prevent air leakage.
Motor mounting
Warning: Do Not energize the cooler until the installation is complete.
1. Place the motor into the cradles. Be sure that the cradles fit into the groove in the
motor grommets.
2. Secure with the saddle clamps provided in the installation package. DO NOT
OVERTIGHTEN.
