Introduction
WHY USE EVAPORATIVE COOLERS IN YOUR WORKPLACE
• The Pro-Kool® evaporative cooler requires little space, has a low initial cost, is inexpensive and simple to
operate and requires minimal scheduled maintenance.
• Due to the design and construction of the cooling pads, cooling efficiency is normally maintained near
optimum throughout the life of the pads (approximately two seasons).
• In many cases, evaporative coolers are a better solution than mechanical refrigeration systems because
they are more economical to operate and maintain and do not use environmentally sensitive and costly
refrigerants.
HOW EVAPORATIVE COOLING WORKS
Evaporative cooling is the same process your body uses to cool itself. When you perspire, and air moves across
your skin, a portion of the perspiration (water) evaporates. Evaporation requires heat to change liquid water to
water vapor and this heat is taken from your skin, producing the cooling effect.
In an evaporative cooler, the cellulose cooling pads take the place of your skin, water instead of perspiration
wets them and a fan moves the air. The air blows across the cooling pads and evaporates moisture. Heat is
drawn from the pads and the air, dropping the air temperature and producing the cooling effect. The cooled air
is then forced through a building or space and displaces the warm air out building openings, cooling the
surroundings. In addition, air velocity increases the cooling effect as it moves over the skin of people in the
airflow path.
Pro-Kool® evaporative coolers are portable and use the latest technology to provide large volumes of cool air,
efficiently and inexpensively for cooling small to medium size areas. Simply adding more units can
accommodate larger areas. With proper sizing and application, a Pro-Kool® evaporative cooler can lower the
effective air temperature by up to 20°. Even in high humidity, the efficiency of the Pro-Kool® evaporative cooler
provides effective cooling.

Description
The Pro-Kool® evaporative cooler is a completely self-contained, portable unit capable of delivering 15 MPH
velocity of air with a temperature drop of up to 20°. The unit is composed of:
•
•
•
•
Level-controlled water supply system
Cooling pad assembly
Motor-driven fan
Frame and housing
The bottom is made of high impact poly and holds approximately 40 gallons at normal operating level (about 6"
deep).
A float-operated valve automatically maintains proper water level when the unit is connected to a water supply.
The bottom rests on, and is fixed to, a rugged steel support frame. Four casters (2 locking, 2 regular) are
attached to the underside of the steel frame.
A pump draws water from the bottom and discharges it through the vinyl hose to the PVC pipes located above
the cooling pads. The PVC pipes distribute water onto the top of the cooling pads; saturating them. Excess
water drips back into the bottom through the holes in the cooling pad support channels.
The cellulose cooling pads sit in support channels and are held in place by the tray and pad support plate.
The fan is powered by a belt drive 1hp electric motor. The fan draws room air through the cooling pads where it
picks up moisture and cools by evaporation. The fan blade then discharges the cooled air.
It is important the cooled space has sufficient air openings so the warmer air can flow out and be
replaced by the cooled air. A closed-in space or high humidity will reduce the cooling effect. See UNIT
PLACEMENT AND OTHER CONSIDERATIONS in the Operation and Maintenance section of this manual.
Water weighs about eight pounds per gallon, so when the unit is full, it weighs over 500 pounds. During
setup and before startup, place the unit in the desired location and then fill the bottom. Do not attempt
to lift the unit once it is filled and be careful to avoid spills when moving it; even over smooth ground.
Do not try to push it over rough or soft ground as you can overstress the wheels and frame and cause
structural and component damage, which is not covered by warranty.

Water Supply System
Hose adapter
The water can be supplied continuously with an ordinary garden hose by attaching it to the supplied hose adapter
to the fill connection, or it can be filled manually.
With a continuous water supply connected, the float valve in the bottom rises and falls with the water level. A
linkage attaches the float to the shutoff valve in the fill connection. As the water level rises to normal operating level
(about 5" deep), the float valve shuts off the water supply. When the water level drops, the float valve opens to
maintain a normal operating level.
After unplugging the unit, the bottom can also be manually filled with a hose or bucket; if a hose connection is
impractical. Simply remove any of the pad sections and place the hose, or pour the water, directly into the bottom.
When you fill the bottom manually it can be filled to a higher level, but make sure someone monitors the filling
operation to avoid overfilling and flooding.
Water damage due to overfilling is not covered by the warranty.
When you run the unit and manually fill it, check the water level frequently so it does not run dry. Operating
the pump without water will damage it or reduce its service life. This is not covered by the warranty. The
cooling effect also stops if the pads are dry.
Pads must be replaced before operating unit.
A drain in the bottom allows you to drain the unit for cleaning and maintenance. A drain cap on the underside
covers the drain during operation. Make sure the cap is in place before filling.
The pump is attached to the fan housing. Plastic ties hold the pump in its proper
position.
The pump can be easily removed and replaced. A small plastic screen covers the
pump inlet to prevent foreign matter from entering and damaging the pump impeller.
A dirty water supply will quickly reduce the unit's performance and the unit
will require more frequent cleaning to maintain cooling effectiveness. Always
try to use a filtered, treated water supply.
A clear vinyl hose connects the pump to the valve. From the valve, a T connector supplies two lines that run along
the top of the pads and up to supply the PVC pipe with water. Each piece of vinyl hose connects to a PVC pipe,
which run horizontally along the top of the inlet above the cooling pads.
The PVC pipes have a series of holes that run the full length of the pipe. The holes direct the water inward at a 90°
angle against a deflector plate to continuously saturate the cooling pads from the top down. Excess water drains
back to the bottom through drainage holes in the bottom support channels which support the cooling pads.
Water cleanliness has a major effect on the cooler's performance. Use a clean water supply and consider a
water softener if your water is hard. Dissolved solids in hard water deposit on the cooling pad surfaces and
reduce the airflow through the unit and therefore the amount of evaporation.
6
Control
The Pro-Kool® PROK142-2 control switch is mounted on the front of the unit in the
upper right corner. It has the following positions:
OFF - Power is off to the blower motor and the pump motor.
LOW VENT - The fan runs at low speed and the pump is off.
HIGH VENT - The fan runs at high speed and the pump is off. Use this setting to
quickly dry the cooling pads for removal and cleaning.
LOW COOL - The fan runs at low speed and the pump is on. Use this setting for low
cooling loads.
Pro-Kool® Control Switch
HIGH COOL - The blower runs at high speed and the pump is on. Use this setting for
maximum cooling.
PUMP ONLY - Pump is on and the fan is off. Use this setting to drain unit only.
Cooling Pad Assembly
The cooling pads are critical for proper, efficient cooler operation. They are made of laminated cellulose (paper)
fibers and arranged to give a large surface area for evaporation and to provide a rigid structure. The shape of
the cells allows high velocity airflow through the pad at a minimum pressure drop. At the same time, the air
passages between the cells force the incoming air to impinge on the wet cell surfaces and maximize
evaporation.
The Pro-Kool® evaporative cooler also acts as an air filter and removes dust and other particles from
the air. This dirt collects on the cooling pads and lowers cooler efficiency. The pads should be cleaned
at least weekly and more frequently in dusty conditions. See REGULAR CLEANING under Operation and
Maintenance.
The pump supplies a continuous flow of water over the pads causing a "sheet flow" which constantly replaces
the water lost to evaporation and keeps the pads saturated.
One cubic foot of the cooling pad material holds about a gallon of water during operation. One cubic meter holds
about 100 liters of water.
The cooling pads are relatively strong but are subject to crushing, especially when wet. Handle them
carefully when you clean them. Crushed cells reduce the total airflow through the unit and therefore
lowers it's cooling capacity.
The cooling pad sections (four total) sit in plastic tray at the back and bottom of the unit. The tray holds the
cooling pads in position and form a back to completely enclose the unit.
Do not remove or handle the cooling pads when they are wet, as they damage easily. Run the fan
without the pump until pads are dry. With normal care, the pads should last at least two seasons. Abuse
or mishandling will reduce their effectiveness and shorten their life.

Operation and Maintenance
UNIT PLACEMENT AND OTHER CONSIDERATIONS
The Pro-Kool® unit(s) should be placed at one end of the building
and an appropriate exhaust fan should be at the opposite end to
pull the cool air from the Pro-Kool® unit and discharge the warm
air out of the building.
Pro-Kool
Pro-Kool
Try to get all the air flowing in the same direction. Do not direct
other fans against the Pro-Kool® unit. It will counter the
Pro-Kool®'s airflow and stop the cooling effect.
Obstructing the airflow from the Pro-Kool® unit severely reduces
the cooling effect.
Avoid using ceiling fans as they disrupt the airflow from the
Pro-Kool® unit.
Use as many exhaust fans as possible to create a natural draft
through the building. This will enhance the Pro-Kool®'s
performance.
UNPACKING AND INITIAL SETUP
The Pro-Kool® 1HP Evaporative Cooler is shipped upright on a
pallet. The Pro-Kool® is fully assembled and ready for service
except for thoroughly cleaning manufacturing dust from the
cooling pads before running it for the first time.
Typical Pro-Kool® Unit Arrangement
CAUTION Be careful when you move the unit. Avoid jarring or dropping the unit to prevent
damage to the bottom.
1.
2.
3.
4.
Cut the straps that wrap the unit.
Remove the shrink wrap.
Ensure the switch is OFF and the unit remains unplugged.
Remove the pad support plate from the back of the unit by
removing all the set screws.
5. Remove the cooling pads from the unit. Pull pad out and then
lift out of drain rail. With one pad out, the rest can be easily
removed in the same manner.
6. Inspect the entire unit for shipping damage.
7. Ensure the fan belt is attached to the motor and fan pulleys.
To ensure it is correct, press your finger on the belt about
halfway between each pulley. It should have about a half-inch
of play. If it is too loose, the V-belt will slap around while
running. If it is too tight, it will cause the pulley bearings to wear
and fail prematurely.
If you notice any damage to your unit, contact your dealer
immediately.
Pro-Kool® assembly
8. Thoroughly clean all four cooling pad sections using a garden hose.
Do not use cleaning fluids or other chemicals to clean the pads as they can cause foaming during
operation. Use only clean water. Refer to page 9 for approved cleaners.
9.
Remove the drain cap from the underside and rinse with a hose to flush any manufacturing dust, etc. from the
unit.
10. Replace the drain cap.
11. Replace the pads.
12. Proceed to NORMAL SETUP.

Operation and Maintenance cont'd
REGULAR CLEANING
The frequency with which the Pro-Kool® is cleaned will depend on the environment in which it is used. The more
dirty the environment the more often it will need cleaning. In most cases the Pro-Kool® will need to be cleaned
weekly.
CAUTION The pads should be dry before you handle them, as they are stronger when dry than
when they are wet and less susceptible to damage. If they are wet, run the unit in the HIGH
VENT position until they are dry. After cleaning, let the pads air dry before you replace them.
1. Turn the switch to OFF and unplug the unit.
2. Check the pads for cleanliness. If they are dirty, remove and clean by spraying with a garden hose, water
only. If they are not dirty you will still need to remove the cooling pads to clean the inside of the unit. Dirty
cooling pads reduce the unit's effectiveness.
3. Use a garden hose to rinse out the bottom and the inside of the unit. The dirt that accumulates is removed
from the air during operation, as the Pro-Kool® unit also acts as an air filter.
4. Remove the drain cap from the underside of the unit and let the unit drain completely. Rinse out any
remaining dirt.
5. Replace the drain cap (finger tighten only).
6. Replace the cooling pads once they are dry.
With proper use and regular cleaning, the cooling pads will last about two seasons. If you handle them
wet and are abusive, however, they will be easily damaged. Refer to page 15 for recommended
conditioning and cleaning chemicals.
NORMAL STARTUP
Some splattering may occur until pads are conditioned (may take several uses).
1. Move the unit to the place where it will be run. Do not attempt to lift or move the unit once it is filled as
damage to the unit or a large spill may occur.
When you decide where to place the unit, make sure there are no obstructions in the way that will
disrupt or block the airflow. Make sure the unit is level at all times. Keep the unit at least three feet away
from walls or other obstructions that will interfere with airflow into the unit.
2. Check to insure the drain cap is in place and secure.
3. Connect the garden hose to the brass hose adapter. Check that there is a washer in the hose connection's
female end.
4. Open the water supply valve and check that water enters the bottom through the float valve by removing
one cooling pad. Allow the unit to fill and check that the float valve completely shuts off the water.
5. If you are manually filling, remove one or more cooling pads and fill the bottom with a bucket or hose.
6. Visually monitor the filling operation to avoid overflowing and causing spill damage.
7. Plug the unit into an outlet.
8. Turn the switch to the low cool position, then to high cool if more air is desired.
CAUTION Do not run the pump without water in the bottom or you will damage the pump.
Running the pump dry will void the warranty on the pump.
NORMAL SHUTDOWN
1. Turn the switch to the HIGH VENT position, and let the unit run until the cooling pads are dry. This will
maximize the life of the pads.
2. Turn the switch to the OFF position. Unplug the unit if you are going to clean the pads or inspect the
components.
3. Shut off the water supply.
4. Drain the bottom if you are going to clean it or store it. It can be done two ways:
a) Remove drain cap from bottom of unit.
b) Attach garden hose to hose fitting labeled DRAIN. Place valve handle in the DRAIN position and put
switch to PUMP ONLY.
Monitor water level and shut pump off when unit is empty. DO NOT RUN PUMP DRY.
5. If the unit will be stored for the season, insure the cooling pads are completely dry, and then remove them.
Wrap them in plastic bags or store them in a clean place where they will not be damaged or get dirty. The
unit should be cleaned thoroughly before storing.

Troubleshooting
COOLING PADS NOT WETTING
1. Make sure the unit has water.
2. Check to insure the control switch is in the proper position.
3. Make sure the pump is running.
4. Pump is running but no water:
a. Ensure hose is connected.
b. Ensure the impeller on the inside of the pump turns freely.
5. Pump is not running:
a. A certified electrician must check wiring from pump to pump selector switch.
b. If the wiring is correct, replace the pump.
FOAMING
Foaming is generally caused by a dirty water supply or contaminated water in the bottom.
1. If foaming occurs, stop the unit, drain it and flush the bottom and insides thoroughly with clean water.
2. Clean the pads and do not use any kind of chemical cleaners. Refer to the REGULAR CLEANING section
for proper procedure for cleaning the pads.
3. Reassemble, refill and restart.
LINE CLOGS OR OBSTRUCTIONS (little or no water flow)
Depending on the cleanliness of the water and the amount of dirt, dust, etc. in the supply air, you may have to
clean the PVC pipes from time to time. Your own experience will dictate the frequency.
1. Turn off the unit and unplug it.
2. Remove the pads.
3. Locate the two PVC pipes in the top housing. Each PVC pipe is secured to an elbow connector by a hose.
Remove this clamp from both PVC pipes.
4. Grip the opposite end of each PVC pipe with pliers and gently twist it out of its Y connector.
5. Direct a jet of water at the series of outlet holes in the PVC pipes to blow them clear.
6. Direct the water nozzle into the end of each pipe and blow them clear. Inspect them for cleanliness and
repeat if necessary.
7. Replace the PVC pipes taking care to ensure the water outlet holes are facing inwards at 90° towards
deflector plate.
Be sure you push the PVC pipes fully onto the elbow, and attach hose clamps.
ODOR CONTROL
