Your Evaporative cooler
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. Tradewinds 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. Tradewinds evaporative coolers are 80% less costly to operate
than refrigerated air conditioners.
IMPORTANT: Do not attempt to install this cooler before reading all of the installation instructions and safety precautions.
Safety precautions
1. All duct work, installation work and electrical wiring must be done by qualified personnel in accordance with all applicable codes and
standards, including fire-rated construction.
2. When cutting or drilling into walls or ceilings, extra precaution should be taken not to damage electrical wiring and other hidden
utilities.
3. Never place a switch where it can be reached from a tub or a shower.
4. When transporting the unit up to a roof for installation, disassemble into parts: top, bottom, blower and louvers. Ensure that the
installer has proper means to transport the unit to the roof. Cooler parts may break if dropped.
5. If the cooler will discharge into a room, install a grill over the discharge. The largest opening in such a grill must be smaller than one
(1) inch.
6. Use this unit only in the manner intended by the manufacturer.
7. Always disconnect power to the unit at the circuit breaker and take steps to ensure power is not reconnected without your
knowledge before attempting any kind of maintenance on the unit.
8. Always take precautions to ensure that you are safe when working on a roof.
9. Do not attempt to service the cooler unless you have the proper tools, and you know how to use them properly.
Installation
Your downdraft Tradewinds cooler must be installed on a FLANGED ROOF JACK in order to support the center of the cooler. DO NOT
sleeve a straight roof jack into the discharge opening of the cooler. Straight roof jacks must be equipped with a flange jack extender.
Note 1: To properly seal the cooler to the flanged jack and prevent air loss, put approximately a ¼” bead of silicone sealant on the full
length of each flange before placing the cooler base on the jack.
Note 2: If you plan to use a flange jack extender, the extender should be fabricated so that it will fit inside the sleeve jack. Also, the
extender should extend a minimum of 6” above the roof on the high side of the roof. Use two (2) self-tapping sheet metal screws per
side to secure the extender to the existing duct.

Location and mounting requirements
 Do not install this cooler near a chimney or other roof vent. The fumes from these can be drawn into the cooler and blown back into
your house.
 Before mounting any cooler on a roof, steps must be taken to ensure that the roof will support the weight of the cooler. See the
warranty page for the operational weight of this cooler.
 If a hole is cut in the roof for the duct, the opening must be framed out in order to attach and support the duct. The duct will
support the entire weight of your Tradewinds cooler. The legs only offer corner support and a means to level the cooler.
 For Side Discharge units, a cooler stand must be provided to support the unit. Tradewinds does not supply cooler stands.
 Unless otherwise indicated, Tradewinds coolers require a 20 amp, 120 volt AC circuit with a standard two-speed wiring circuit to the
cooler.
 Tradewinds coolers require a suitable ¼” water line. Install a shutoff valve at the beginning of the water line.
 The duct openings are as follows TC451 17 ¾” square
TS451 17 ¾” square

Louver latches
The latches at the corners of your Tradewinds cooler are designed to hold the louvers securely in place and prevent gapping which
degrades cooler performance.
 To unlatch the louvers for removal: Slip a flat head screwdriver under one corner of
the latch and pry out gently. If you pry too hard or too quickly on the latch, it may
pop out of place and fly off the unit resulting in a lost latch.
 Unlatch the louver at the four (4) corners. Remove the louvers one (1) at a time.
 Remove the louver by tilting it out at the top and lifting it away from the unit.
 To install the louver: place the louver into the slot in the cooler pan and tilt it up into
place. Place the second louver adjacent to the first. Ensure that the embosses (in
the corners of the louvers) fit together snuggly. Close the latches over the
embosses.
 Do not hit or force the louvers into place. If the louvers do not fit together easily, it
may be that something is wrong with the installation.
The cooler must be level for proper operation
To level your Tradewinds cooler, install a LEG EXTENSION KIT (provided on downdraft models only). Refer to instructions included
with the leg extension kit for installation. If the cooler is to be placed on a stand, the LEG EXTENSION KIT need not be used. To
check the cooler for level, place a level on the cooler base. DO NOT use the top of the cooler to check for level.
Float valve
On the downdraft models a flange has been molded into the backside of the blower
near the water line. On the side draft models a flange has been molded into one of the
vertical blower supports.
1. Remove the compression nut, ferrule, ring nut and fiber washer from the stem of the
float.
2. Place the stem of the float through the hole in the flange.
3. Place the fiber washer over the stem of the float and thread the ring nut back on to
the stem and tighten so the water outlet faces straight down.
4. Bring a suitable ¼” water line into the cooler through the small hole provided in the
base.
5. Place the compression nut and then the ferrule onto the water line.
6.Insert the water line into the stem of the float, slide the ferrule to the stem and thread
the compression nut on to the stem. DO NOT over tighten the compression nut. If the fitting leaks, tighten the compression nut a
little at a time until the leak stops.
Overflow fitting
Reservoir
The water level should be adjusted so that it reaches ½” below the top of the overflow pipe. To
allow for draining the pan, the bushing is threaded to accept a standard, female garden hose
fitting.
1. Place the bushing, with the rubber washer, through the hole provided in the base of the cooler.
2. Secure from below the base with the ring nut provided. DO NOT over tighten the ring nut.
This may damage the rubber washer and allow the fitting to leak.
3. Thread the overflow tube into the bushing and hand tighten. Over tightening the overflow tube
may cause damage to the tube. If the fitting leaks and tube is properly tightened, try wrapping
the threads of the tube with plumber’s tape.
Motor installation
1. Remove the motor from the box, inspect for shipping damage and ensure that the horsepower
and voltage are correct.
2. Remove the motor from the cradle provided. This will make installing the cradle
easier.

Electrical connections
Tradewinds coolers must be wired in accordance with applicable codes and regulations. If you are not familiar with local wiring codes,
SEEK THE ASSISTANCE OF A LICENSED PROFESSIONAL ELECTRICIAN.
WARNING: To reduce the risk of fire or electrical shock,
do not use this fan with any solid-state speed control device.
4
Motor Pulley
1. The motor pulley should be installed on the motor shaft with the threaded side out.
2. Align the motor pulley with the blower pulley.
3. Tighten the set screw A (5/32 hex screw) opposite the threaded side to secure the pulley to
the shaft. Be sure to tighten the set screw onto the flat side of the shaft.
4. Loosen set screw B (5/32 hex screw) on the threaded side of the pulley. This will enable the
outside jaw of the pulley to rotate.
5. Turn the outside jaw clockwise until the pulley is fully closed, then turn the ‘outside jaw’
counter-clockwise until the set screw is positioned over the nearest flat spot.
6. From the closed position, open the pulley (turn outside jaw counter-clockwise) 3 turns.
Tighten the set screw. It is important that the set screw is not tightened onto the threads.
This will damage the pulley.
7. After the unit is fully installed, with the fan on HI speed, the pump off and all the louvers in
place, check the motor amperage using an ammeter. The amperage should read what the manufacturer recommends on the motor
name plate. If this is not the case, adjust the amperage by closing (increase amperage) or opening (decrease amperage) the pulley
½ turn. Recheck amperage after each adjustment. To prevent motor damage, never exceed the amperage listed on the motor.

5
Belt installation and adjustment
To install belt:
1. Place the belt over the motor pulley.
2. Place the free end of the belt into the blower pulley.
3. Rotate the blower pulley until the belt lies fully in the groove.
Ensure not to pinch fingers between the pulley and the belt
Test the belt tension by pressing on the belt mid-way between the pulleys. With only 3 to 4
pounds of pressure, you should be able to deflect the belt between ¾ and 1 inch.
If the belt needs to be adjusted:
1. Push up on the motor to get an idea of how much the belt tension bracket should be adjusted.
2. To tighten the belt: Remove the belt and adjust the bracket accordingly.
3. To loosen the belt: Remove the belt and adjust the bracket accordingly.
After the installation is complete, fill the cooler pan with water. Check for leaks at the drain
coupling and the float valve coupling. Adjust the water level by resetting the adjustment screw at the base of the float rod. Check that
the base of the cooler is level. To prevent rust a coating of good quality axle grease may be applied to the shaft and bearings.
Post installation inspection
1. Cooler is securely fastened to the roof jack
2. Base is level (check after full of water)
3. Ensure duct is sealed
4. Check all connections for water leaks
5. Check for correct water level
6. Ensure all electrical connections and wiring conform to
applicable codes and motor and pump are plugged into
junction receptacle
7. Ensure motor is securely fastened to mount, the pulleys are
aligned and the belt is tensioned properly
8. Ensure the hose is installed securely to the pump and to the
water distributor
9. Turn on main power supply
10. Check pump operation by turning the control switch to
PUMP ONLY. Check that all pads wet evenly
11. Check the high and low fan speeds with and without the
pump running.
Operation
 Before you put your new cooler into operation, pour a cap full of laundry fabric softener (any brand) into the water and run the cooler
on PUMP ONLY for 10 to 15 minutes or until the pads are thoroughly saturated.
 You control the airflow of the cooler into what rooms you wish cooled. To allow cooling in a particular room, open a window, exterior
door or vent in that room. The cool air from your cooler will tend to go to the rooms that have some sort of opening to allow for
exhaust to the outside of the house.
 A rule of thumb used for deciding how far to open each window or how many windows to open is to allow 2 square feet of exhaust for
each 1000 CFM of airflow. For example, the TC451 delivers 4100 CFM; therefore, you will need approximately 8 square feet of
exhaust area.
For replacement purposes…
Pads: Use only HiKool Plastic UL Class II evaporative pads.
Pumps: Use only three-pronged molded plug UL listed pumps 5000CFM for TS451 & TC451 – 7000CFM for TS571 & TC571.
Motors: use only evaporative cooler motors. ½ HP TS451 & TC451 – ¾ HP TS571 & TC571.
Maintenance
Warning: Always shut off the electrical power to the unit at the fuse or breaker box and unplug the motor, pump from the junction
receptacle and shutoff the water supply before attempting any type of maintenance or service work.
Oiling
1. Oil the bearings and motor often (twice a season minimum).
2. The bearings are provided with oil cups. Lift the hinged lid on the cup and add a couple of drops of oil. Do not over oil, excessive oil
can enter the air stream.
3. If the motor is provided with oil cups, then oil the motor when you oil the bearings. Do not over oil, if oil gets into the motor, damage
may occur.
Cleaning the water distributor
1. Disconnect the vinyl tubing connecting the pump and water distributor.
2. Turn the water distributor clamps in the top of the cooler, lower the distributor and pull (twist) apart at the tan connectors.
3. Tap ends lightly on a hard surface to dislodge mineral deposits and flush with a garden hose.
4. A nail may be used to clean deposits from the holes in the distributor. DO NOT distort or enlarge holes while cleaning.
Do not attempt to clean the water distributor while on the roof.
Mineral build up
 Mineral deposits may collect on the louvers and around the base of the cooler. These deposits may be removed easily with a little
water and a nylon scrub brush (never use a wire brush on this cooler).
 In areas with concentrated minerals in the water, change the water often to prevent high mineral content in the reservoir.
 An inline water filter device, installed on the water line, will help keep mineral build up to a minimum.
 Change the pads when they become mineral laden and dirty. In most areas, a set of pads will not last all season.

Post season
Perform this maintenance as soon as possible after the last day of usage or when shutting down the cooler for extended periods.
1. Drain water
2. Remove pump
3. Clean mineral deposits from pan and louvers
4. Remove the belt and hang it from the motor pulley
5. Cover the cooler with a high quality cooler cover to keep dirt and water
out of cooler
Pad removal and installation
For safety reasons, do not attempt to change the pads on the roof.
1. Unhook pad retainers above and below pad. Remove and set aside.
2. Remove old pad and discard.
3. Place the new pad in the louver so that the top of the pad covers at least ½ of the water tray slots.
Center the filter over the pad.
4. Replace pad retainers.
