1. Read all instructions carefully.  
2. Electrical connections should be done by a qualified electrician,  
so that all electrical wiring will conform to your local codes.  
3. Always turn OFF POWER and UNPLUG motor and pump inside  
the cooler before installing or performing any maintenance.  
4. Your cooler will run on either 120V or 240V A.C., single phase,  
60 Hz (cycle) current.  
5. Motor and pump have a grounded, molded plug and an automatic  
thermal overload switch which will shut motor off when it  
overheats. The motor will restart automatically when it cools  
down.  
WARNING: To reduce the risk of fire or electric shock, do not use  
this fan with any “solid-state fan speed control device.”  
HOW EVAPORATIVE COOLERS WORK  
Evaporative cooling is nature’s way of cooling. When air is  
moved over a wet surface, water is evaporated and heat is  
absorbed. When stepping out of swimming pool with the  
wind blowing, evaporative cooling makes you feel cool, even  
though the air may be warm.  
This unit works on the same principle. Air is drawn across  
wet filter pads where the air is cooled by evaporation and then  
circulated throughout the building. It is this combination of  
cooled air and the movement of air over the skin which makes  
it feel cool.  
Unlike refrigeration systems which recirculate the air, an  
evaporative cooler continually brings in fresh air while  
exhausting old air. You are completely replacing the air every  
2 to 4 minutes by opening windows or doors, by using Up-  
Dux® ceiling vents, or a combination of both. The air is always  
fresh, not stale, laden with smoke and odors as happens with  
refrigerated air conditioning.

SCALE BUILDUP PREVENTION  
As water evaporates, minerals that were in the water will remain. Over time this  
accumulation of minerals will cause scaling on the pads and in the reservoir. We  
recommend the installation of either a bleed-off kit (included in standard 4000RLD4  
unit) or a purge pump (installed in contractor 4000CRLD4 unit) to help prevent  
scale build up and increase the life of the unit. A purge pump will drain the pan  
every few hours of pump operation, to keep fresh water in the unit. A bleed-off kit  
will continually bleed off a small portion of water while the pump is running allowing  
fresh water to continually replace the old stagnate water. Follow the instructions  
below for installing the bleed-off kit.  
BLEED-OFF KIT  
Pump Hose  
Bleeder Tee  
Bleed Tube  
Restrictor  
1.  
Cut the pump hose and insert the barbed ends of the bleeder tee into each  
cut end.  
Overflow Pipe  
2.  
Insert one end of the bleeder tubing onto the bleeder tee and run the other  
end out of the cooler through the overflow pipe.  
Note: A restrictor clamp is provided which, if desired, may be installed onto the  
bleeder tubing to restrict the amount of water being bleed off. The amount of water  
to bleed off depends on the quality of the water in your area. Start with 1-2 gal/hr  
and increase if needed.  
AMPERAGE DRAW AND BELT TENSION  
CAUTION: No attempt should be made to completely install this unit without the aid of an electrician or  
someone familiar with testing amperage draw. Failure to comply with these instructions may void your  
warranty.  
This unit is equipped with an adjustable motor drive pulley for adjusting the blower wheel speed to the proper loading for different  
duct systems. It is important that the motor drive pulley is adjusted to correct size to ensure maximum air delivery without damage  
to the motor. Be sure to follow these instructions carefully.  
Motor  
1.

3.  
Ensure electrical connection of unit is complete and in accordance with all  
safety standards and local requirements.  
Pulley  
Motor  
Reinstall inspection panels. Apply power, turn water and pump on and allow  
cooler to run for a few minutes to wet pads.  
Decrease  
Amperage  
Belt  
Turn off the pump and check amperage and verify it conforms to amperage  
listed on the specification label on motor.  
Blower  
Pulley  
If amperage draw is less than motor rating, disconnect electrical power  
and remove louvered sides. Unplug motor inside cooler, this will protect  
you from someone turning the unit on while you are working inside. This  
should be done for your safety. Adjust pulley to a larger diameter and  
readjust belt tension. Plug motor in, install louvered side, and retest amperage  
draw. Repeat this process until correct amperage draw is attained.  
BELT TENSION  
Note: Increasing motor pulley diameter increases amperage draw. Decreasing  
motor pulley diameter decreases amperage draw.  
3 Lb. Pressure  
3/4 Inches  
CAUTION: DO NOT operate cooler with larger amperage draw than  
specified on motor plate. Motor damage will occur.  
4.  
Check belt tension after adjusting pulley. A 3 lb. force should deflect the belt 3/4  
inches. Readjust belt if needed by loosening adjustment screw, rotate motor until  
you have the correct belt tension, then re-tighten screw.

OPERATION  
NOTES: 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.  
To eliminate the delivery of hot air when starting the cooler, start the pump only for the first few minutes, then turn on the blower  
motor.  
THERMOSTAT OPERATION (CONTRACTOR MODEL 4000CRLD4)  
Automatic Operation (Cool Mode)  
The fan and water pump are controlled automatically to achieve the desired comfort level.  
This mode is activated by pressing the ‘Mode’ button until ‘Auto’ is displayed on the LCD. The ‘Mode’ button changes the control  
from Off to Auto to Manual and back to Off.  
The Set temperature (the target temperature for control) may be altered by repeatedly pressing or holding the ‘Up’ or ‘Down’  
buttons. The LCD will display the ‘Set’ rather than ‘Room’ temperature for a short time after pressing the ‘Up’ or ‘Down’ button.  
On starting or after the pump has been off for a period of time, the pump will start without the fan to allow the media to absorb  
water. This is called Pre-wet and lasts for 2 minutes, indicated by ‘Pre-Wet’ flashing on the LCD. The Pre-Wet cycle can be  
bypassed by pressing the ‘Fan’ button and then pressing the ‘Mode’ button until ‘Auto’ is displayed.  
The thermostat will cycle the fan setting between High speed, low speed and off depending on room temperature. If the room  
temperature drops 2 degrees below the set point temperature, the fan will turn off. At 1 degree above the set point temperature,  
the unit will start on low speed. If the room temperature rises to 4 degreees above the set temperature, the fan will change to high  
speed and will remain until the room temperature drops to 1 degree above the set point, where it will change to low speed.  
The thermostat allows the operator to calibrate the room temperature reading. Pressing the up and down arrows simultaneously  
for 5 seconds will enter the calibration mode. A temperature adjust setting of -3 to 3°F can be selected. After no activity for 5  
seconds, the thermostat will exit the calibration mode and the room temperature will be adjusted by the selected value.  
During automatic operation, the control performs a water purge cycle every 8 or 12 hours of pump operation. This interval can  
be toggled between 8 or 12 hours by simultaneously holding the ‘Pump’ and ‘Fan’ buttons for 5 seconds. The selected interval is  
displayed for a short time. This action also starts a manual dump cycle.  
Manual Operation  
The fan speed and pump are set by the user.  
To activate the manual mode from the ‘Off’ state, press the ‘Mode’ button until ‘Manual is displayed. If the control is in the ‘Auto’  
mode, you can change to manual mode by pressing either the ‘Mode’, ‘Fan’ or ‘Pump’ buttons. Pressing the ‘Fan’ button changes  
the fan from High to Low to Off and back to High. Pressing the ‘Pump’ button changes the pump from On to Off and back to On.  
The LCD will display ‘Manual’ on the left and the fan and pump settings on the right. The fan speed will be displayed as Fan Hi  
or Fan Lo. If neither are displayed the fan is off. The pump status will be displayed by the LCD as ‘Cool’ (if the fan is running)  
or ‘Pre-Wet’ (if the fan is off). With the fan and pump both running ‘Cool’ will be displayed. If only the fan is running ‘Vent’ will be  
displayed.  
110524-1

Time Delay Operation (Timer Mode)  
Delayed start or finish in ‘Auto’ or ‘Manual’ mode.  
The ‘Timer’ button is used to set a delay period between 1 and 12 hours in 1 hour increments.  
If the cooler is operating (in ‘Auto’ or ‘Manual’ modes) when the ‘Timer’ button is pressed, the delay period determines when the  
cooler switches off. If the cooler is Off when the ‘Timer’ button is pressed, the delay period determines when the cooler starts in  
‘Auto’ mode. The set temperature will be the last setting when running in ‘Auto’ mode.  
‘Timer Delay’ and the remaining time are displayed on the LCD while the timer feature is activated.  
You can cancel the Timer function at any time by pressing the ‘Timer’ button. The ‘Timer Delay’ indicator will no longer be  
displayed.  
In The Event Of A Power Outage  
When power is restored after a power outage, the thermostat will resume operation in the mode selected prior to the power outage.  
If the timer mode is active, the time will be restored to the hour indicated prior to the outage.  
AIR EXHAUST  
For an evaporative cooler to be effective, there needs to be adequate exhaust. If there is not adequate exhaust, pressure and  
humidity will build up in the building. You exhaust by opening doors or windows to allow the old stale air in the building to escape.  
Attic exhaust dampers may also be installed to exhaust the air into the attic. The combination of attic exhaust dampers and a  
thermostat can provide a completely automatic operation.  
An often misunderstood concept of evaporative cooling is the amount of air that should be exhausted. How much should you open  
your windows? The following two methods will help you determine the amount to open your windows.  
WINDOW AREA/CFM METHOD  
For proper air flow, allow an opening of at least 2 square feet (288 square inches) for each 1000 CFM rating of your unit.  
Example: At 3640 CFM, model 4000RLD4 requires 7.3 square feet (1050 square inches) of opening (3320/1000 * 2 = 7.3).  
Multiply the number of windows by window width in inches and divide this into the number of square inches required for your size  
unit. This will give you the height to open windows. In this example, four 36 inch wide windows should be opened 7.3 inches each.  
TISSUE SUCTION METHOD  
1.  
2.  
3.  
4.  
Take a piece of tissue paper and cut it lengthwise into 3 equal strips.  
Turn your cooler on high cool.  
Open one window at least six inches wide in each room that you want to cool.  
Take the piece of tissue paper and put it up against the screen of the open window furthest from the cooler discharge  
opening. Let go of it. It will do one of three things.  
IF:  
IF:  
IF:  
It falls down.  
It plasters itself to the screen.  
It stays on the screen lightly.  
THEN: CLOSE all of the windows one inch and try step 4 again.  
THEN: OPEN all of the windows one inch and try step 4 again.  
THEN: PERFECT. You are done. Enjoy your cooler.  
Notes:  
When switching to low cool, you must re-balance your home. Repeat step 4.  
Once you balance your home you can cool some areas more than others by opening those windows  
more and closing the others by the same amount. Repeat step 4 to make sure your home is still air balanced.

MAINTENANCE  
Regular maintenance on your cooler will increase performance and extend the life of your cooler.  
WARNING: Before accomplishing any maintenance ensure power is turned off and the motor and pump are  
unplugged.  
START OF SEASON MAINTENANCE  
Accomplish these basic steps before the temperatures require cooling in case you have to acquire replacement parts.  
CLEAN OR REPLACE MEDIA  
1.  
With power DISCONNECTED, remove louvered doors.  
2.  
Inspect filter media. Scale buildup on the media will obstruct the airflow and cause the media to be less absorbant. If there is a  
lot of scale buildup, check the bleed or purge settings. The bleed-off may be plugged, or the purge cycle may need to be more  
frequent. A dirty filter will be less efficient and will cause a decrease of cooling in the home.  
3.  
4.  
5.  
6.  
If media is dirty, remove from the louvered side. Remove the top media support brackets, loosen the water trough screws and raise  
water trough, then lift out media.  
Clean the media with a garden hose. Light scraping may be required to remove mineral deposits. Do not use harsh detergents or  
pressure washers in cleaning. Make every effort to keep the media intact.  
The original media has a standard life of 5 years, but in areas with very high mineral content the media may have to be replaced  
sooner. If cooling efficiency is not adequte, replace the media.  
When reinstalling existing or installing new replacement pads, we recommend using original equipment, MasterCool® media  
replacement pads for highest cooling capabilites.  
Blower Bearing  
Oil Cup  
OIL BEARINGS  
1.  
The blower bearings should be oiled each year with non-detergent 20/30 weight oil.  
2.

THE MANUFACTURER IS NOT RESPONSIBLE FOR DAMAGES OF ANY KIND, INCLUDING INCIDENTAL AND  
CONSEQUENTIAL DAMAGE OR LOSS OF PROFITS OR REVENUES.

No employee, agent, dealer or other person is authorized to give any warranties or conditions on behalf of the manufacturer.  
The customer shall be responsible for all labor costs incurred.
