Frequently Asked Questions
Question: Is the Cool Boss an air conditioner?
Answer: No. it is an evaporative air cooler, sometimes called a swamp cooler. The fan pulls in hot
outdoor air, a water drip system releases water, the water drops evaporate when they meet the hot air,
lowering the air temperature by up to 26°F, and the fan blows the cooled air in the direction you point
it.
Q: How big of an area can a Cool Boss cool?
A: 2,000 to 2,500 square feet, depending on the layout of the space you are cooling.
Q: What’s the best way to set up my Cool Boss?
A: With the back of the unit facing a source of hot, dry air and the front facing the area you want to
keep cool. It will need to be near a power source also. And remember, it is portable. So you can move
it to where you need it; it does not have to stay in the same place the whole time.
Q: Does it require special water?
A: No. Clean, ordinary tap water.
Q: Is it hard to control the Cool Boss?
A: Not at all. There a few, easy-to-understand controls on the unit. It also comes with a remote
control, so that you can turn it on or off or change settings from wherever you happen to be.
Q: What about maintenance?
A: Very little. Basically, keep the water tank filled with clean tap water and clean the cooling pad once
in a while. Dirt and other pollutants from the environment accumulate in the cooling pad, so it is best to
clean it every so often. Do not clean the cooling pad by spraying it with water with the cooling pad in
place; instead, remove the cooling pad using the procedure in Maintenance, then clean it.
Q: Anything else I should know about my Cool Boss?
A: It includes two impressive features. The louvers on the front of the unit can move from side to side,
helping the Cool Boss to cover more area. And the negative air ionizer releases negatively charged air
molecules into the air, which grab onto dust and other particles and pull them out of the air, so you do
not have to breathe them. It sounds complicated, but just give it a try.

The Remote
The following figure shows the remote that comes with the unit (in the box with the casters).
Setup
To set up the CB-30:
1. Put on the casters. The casters come in a box with the remote. Two of the casters have
brake locks; they generally go on the front.
⚠WARNING You must wear the proper protective equipment at all times during setup: leather
gloves, steel-toed boots, and back belts are
required .
2. Find a location. Find a suitable location for the unit (hot air to the rear, area to cool to the front).
It should be inside, near an appropriate power source, and in a low-traffic and well-ventilated area.
Never roll anything heavy over the power cord. Try to find a location where people will
not be constantly walking over the power cord, as this is a tripping hazard.
Do not run the
power cord under a rug or other flammable material
.
⚠WARNING This equipment has internal arcing or sparking parts that should not be exposed to
flammable vapors. The unit must not be located in a recessed area or below floor
level.
⚠CAUTION Cool Boss requires adequate air flow for intake and exhaust. Verify a window or
door is open.
⚠WARNING Verify the Power Cord and Water Supply Hose is routed to prevent a tripping
hazard and is not routed under carpets or across sharp edges.
3. Lock two casters. Once you have settled on a location, press down the locking mechanisms
on the two casters that have them; using your foot is a good way to do this. To move the unit later,
flip up the locking mechanisms on the locked casters; again, feet work great for this.
⚠CAUTION Do not start the CB-30 until you have locked the two casters; this ensures that it
stays in place.

CB-30 Cool Boss Evaporative Air Cooler 11 P/N 5900140 — September 2021 — Rev. C1
4. Connect to an appropriate power source. Before connecting this unit to a power source,
first verify the voltage that will be required by studying the model nameplate affixed to your
machine (110 VAC, 60Hz, 1Ph, 15A or 208-230 VAC, 60Hz, 1 Ph, 15A). If your Cool Boss is
equipped with a Plug not applicable to your power source, change the Plug as required using only
an approved NEMA-rated plug. Connect only to a fused and grounded electrical supply.
It is recommended that a separate circuit serving only the Cool Boss be provided. Use an outlet
that cannot be turned off by a switch. If an extension is required, use only cords with polarized
and/or three-prong plugs no longer than 100 feet in length. Never use an extension cord that is not
properly rated to handle the power load. When making electrical connections, ensure that local
and national codes are adhered to. Use only with GFCI-protected receptacles.
For 110 VAC operation, the Unit comes from the factory with a Power Cord and Plug; an
Electrician is
not required to connect to a 110 VAC power source. For 220 VAC operation, you
must have an Electrician replace the pigtail that comes with the unit with the appropriate Power
Cord and Plug.
⚠DANGER All wiring must be performed by a licensed, certified Electrician in accordance with
local and national electrical codes.
5. Fill the water tank. Find the Water Inlet on the right side of the unit (looking at it from the
front). Add
clean water. Do not overfill; fill to the Max Fill level only. Water temperature must be
less than 113°F (45°C). You can also connect the Water Source Connector on the left side of the
unit to a water source using the .75 inch NPT fitting; this makes it easier to fill the water tank.
Either way, be careful not to overfill the tank.
6. Check the pad. The cooling pad needs to be correctly installed before you start the CB-30.
7. Make a visual inspection. Before use, check for problems with the unit. Do not use the
CB-30 if you find a problem with it
. If you find a problem, take the unit out of service, then
refer to the Maintenance and Troubleshooting sections for more information. If you cannot
resolve the issue, contact your dealer, email Cool Boss at [e-mail], or call
[phone].
Operation
To operate the CB-30:
•Press Power. You can press the power button on the Control Panel or the Power button on the
remote; either way starts the fan. Check the Control Panel screen to see current settings.
•Press Cool. Starts the cooling function; the pump begins circulating water.
⚠CAUTIONMake sure there is water in the water tank before pressing Cool; if not, the water
pump motor could burn out.
•Press Speed. Select between High, Medium, and Low fan speeds. On the Control Panel, press
the Speed button to switch between fan speeds. On the remote, press the button for the fan
speed you want.
⚠WARNING Keep hands and fingers away from the fan when it is running.
•Press Ion. The built-in ionizer starts releasing negative ions, resulting in cleaner air.
•Press Swing. The louvers on the front of the unit begin moving, which helps to circulate the cool
air more efficiently.
•Refill the water tank. When it gets low, refill the water tank. It holds approximately 17 gallons.

CB-30 Cool Boss Evaporative Air Cooler 12 P/N 5900140 — September 2021 — Rev. C1
⚠CAUTION Always dry the Cooling Pad after use by turning off the Cooling and running without
circulating water; do this approximately 15 minutes before shutting the unit off. This
ensures that the Cooling Pad continues to function optimally.
Maintenance
⚠DANGER Disconnect the unit from its power source before performing any maintenance.
Verify the unit is locked out from power and cannot be re-energized while
maintenance is being performed. If your organization has Lockout/Tagout policies,
make sure to implement them before servicing your Cool Boss.
⚠WARNING Keep hands and loose clothing clear. Rotating Fan Blades can cause serious injury.
⚠WARNING Disconnect the Power Cord when cleaning the Cool Boss and exercise care to
avoid splashing water on the motor or internal electronics.
To maintain the CB-30:
•Change the water when it gets dirty. Dirt and other pollutants from the environment will
get into water. The cleaner the water you use, the fresher and cleaner the air you get. Cool Boss
recommends changing the water frequently, even if you are not using it much.
•Check the GFCI monthly. Check the GFCI outlet the CB-30 is plugged into once a month to
ensure it is working and protecting you from electric shock.
•Clean the outside of the unit. Wipe down the outside of the unit once a month using a
damp towel or equivalent.
⚠WARNING Do not spray the CB-30 with water. If it gets inside, you could damage the motor
and/or other parts of the electrical system.
•Do not open the Control Panel compartment. The Control Panel compartment has no
user-serviceable parts inside; do not open it.
•Clean the cooling pad on a regular basis. Dirt and other pollutants from the environment
get caught in the cooling pad. Clean it regularly to keep the air fresh and clean. See procedure on
following page.
⚠CAUTION Always dry the Cooling Pad after use by turning off the Cooling and running without
circulating water; do this approximately 15 minutes before shutting the unit off. This
ensures that the Cooling Pad continues to function optimally.
⚠CAUTION Cool Boss recommends wearing gloves when handling the cooling pad.

CB-30 Cool Boss Evaporative Air Cooler 13 P/N 5900140 — September 2021 — Rev. C1
⚠WARNING Disconnect the unit from its power source before performing any maintenance.

4. Unfasten the grille by removing the 12 screws holding it; four on each side and four on the bottom.
5. Pull the grille off, then remove the cooling pad. You may need to apply a little pressure to get the
cooling pad out.
6. Rinse the cooling pad under running water to clean it. Do
not use highly pressurized water or air to
clean the cooling pad.
7. Take off the drainage valve on the bottom of the unit to drain any remaining water, then clean the
water tank with a soft cloth. Clean the water sensor, water pump, and drainage valve. Put the
drainage valve back on.
8. Clean the outside of the unit with mild soap and a soft cloth. Do not use strong chemicals; they
could damage the unit.
9. Put the cooling pad back into place; first put the bottom in and then the top. You may need to
apply some pressure to get the top of the pad into place.
10. Fasten the grille by replacing the 12 screws, then put the crosspiece into place and screw it in.
Make sure to put the holes in the bottom of the crosspiece over the tabs at the top of the grille.
