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 in a plastic sleeve.
1.2 Evap-O-Matic – Chemical Water Treatment. Operate your unit 2
weeks – flush out old water – add clean water – then add Chemical Water
Treatment tablet. Note; Tablet makes water foam which can cause unit to
spit droplets of water temporarily. Foam subsides in 1 – 2 working days.
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 EC48B2 unit was shipped on a wooden skid covered with a cardboard cover
and lid – strapped. First remove the straps then you may lift the whole cardboard
box off the unit and skid. Your MaxxAir must now be lifted off the wooden skid.
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 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 – open the water flow valve (located on the front of your unit) only one and quarter (1
1/4) turns. This water flow valve adjusts the amount of water to the unit. Next, 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. (If the water is dripping off of the pads on to the floor – turn your fan on low –
close the flow valve a little to slow the water flow. After the pads are wet – you can
open the valve to 1 ¼turn. Allow water to run for 10 – 15 minutes on new cooling
pads to totally saturate them with water. Once your units cooling pads are saturated –
NOTE: EXTENDED COOLING ZONE: 40’ TO 50’ FROM MAXXAIR UNIT.
AIR MOVEMENT INCLUDES WARM AIR MIXING WITH COOLED AIR.
