MaxxAir Portable Evaporative Cooler
1.0 Introduction
•Your MaxxAir was tested 3 ways. Your unit was tested for 1. Maximum air flow at operating static pressure.
Only MaxxAir is tested in operating conditions with 2. Water and 3. Electricity before it is shipped.
•MaxxAir is easy to operate – needs only tap water and electricity to operate.
•MaxxAir is easy to move – roll your MaxxAir to the area you want to cool. MaxxAir comes standard with straight
and swivel / lock casters which make moving your MaxxAir a breeze.
1.1 Quick Start – Your Quick Start Information is located inside the
information packet shipped with your unit.
Look on the front of your MaxxAir packaging in a plastic sleeve.
1.2 Evap-O-Matic Tablet – Chemical Water Treatment. Operate your unit
for 2 weeks – then, flush out old water – add clean water – then add ½
Chemical Water Treatment tablet. Note: Tablet makes water foam which
can cause unit to spray water temporarily (for a day or two). You can
order more tablets by calling 1.800.433.1626.
2.0 How Evaporative Cooling Works
Keeping in mind that regular fans only circulate same temperature air -
same humidity – your MaxxAir portable evaporative cooler takes that
same existing air, combines it with evaporating water (which dramatically lowers the temperature) immediately relieving
hot, dry areas, similar to the conditions when a natural rain storm approaches, the temperature drops noticeably cooler,
because the air is saturated with water. Because your air is now saturated with water it becomes noticeably cooler. In high
humidity areas the temperature will not be as cool – however, the MaxxAir was engineered efficient to evaporate
perspiration and sweat from employees to keep them cooler.
3.0 Unpacking your new MaxxAir unit
Note: Carefully examine your MaxxAir shipping carton for damage
before opening. If your carton is damaged – notify the shipper immediately!
Your EC18” unit was shipped strapped a wooden pallet inside a cardboard box.
First remove the straps then you may open the cardboard box. Your MaxxAir
comes with a box of casters. Attach swivel casters to fan side of unit and straight
casters to pad side. Use a 3/8” wrench to attach casters.
4.0 Set-up your MaxxAir unit.
Roll your MaxxAir unit to a level surface and lock the swivel casters to prevent
accidental movement.

4.1 Connecting the electrical supply
All MaxxAir models require regular 3 prongs, ground with 120 volt power supply. Plug electrical cord into receptacle. If
using an extension cord be sure it is rated for at least 20 amps for the distance your cord is running. To be safe – make sure
no other equipment, such as a radio or electrical equipment, is plugged into the same circuit. The MaxxAir should run
smoothly on 20 amp, 120 volt, and 60 Hz circuit.
4.2 Connecting the water supply
Connect standard water hose to female fitting on the right side of your MaxxAir (looking at the fan blade side). If your water
pressure is above 60 pounds per square inch (p.s.i.) you must use a pressure regulator (which can be found at your local
hardware store). Note: Do not connect to water source exceeding 60 p.s.i. – this can cause damage to your MaxxAir.
5.0 Operating procedures
Back your MaxxAir unit up to a fresh air source such
as an open door or window so the unit can pull in
fresh air from the outside. Next, make sure you have
a natural exhaust at the opposite end of the room, bay
or building such as a window, door or bay door. This
will ensure maximum efficiency from your unit.
Finally make sure there are no obstructions between
your MaxxAir and the people / area you need to cool.
5.1 Filling the units reservoir with water
Once your water hose is connected, turn water on and
fill the reservoir with water. Listen carefully. You
can hear water filling the reservoir. Check your water
connection – make sure there is no dripping. Once the reservoir is filled with water the float valve will automatically shut off
the water source. When you no longer hear the water running – you know that the float valve is fully operational (the water
turns off automatically) and you are now ready to turn on the water pump. Warning! Do not run water pump without
water in the reservoir.
5.2 Turn-on pump
To turn-on the water pump - flip the toggle switch for the water pump to on. Switch is located on front side of unit.
Warning! Do not run water pump without water in the reservoir. The water pump will now begin pumping water to the
top of the unit so that gravity will allow the water to run down the backside of unit inside and on the cooling pads. Once
your MaxxAir cooling pads are saturated – then, you are ready to turn fan on high and begin to feel the cooling effect from
your new MaxxAir. Note: After your cooling pads are broken in (typically takes 1 -2 weeks in operation) it will take less
time to saturate pads for start-up. This is a good time to dump the old water – add ½Evap-O-Matic Chemical Water
Treatment tablet and refill with fresh water. (Simply remove a cooling pad to place tablet inside of water reservoir).
NOTE: EXTENDED COOLING ZONE: 40’ TO 50’ FROM MAXXAIR UNIT.
AIR MOVEMENT INCLUDES WARM AIR MIXING WITH COOLED AIR.
