1.0 Introduction
 Your QuietCool was engineered to be the most efficient portable evaporative cooler manufactured. It was

manufactured and assembled at our plant in Houston, Texas.

 Your QuietCool was tested 3 ways. Your unit was tested for 1. Maximum air flow at operating static pressure.

Only QuietCool is tested in operating conditions with 2. Water and 3. Electricity before it is shipped.

 QuietCool is easy to operate – needs only tap water and electricity to operate.
 QuietCool is easy to move – roll your QuietCool to the area you want to cool. QuietCool comes standard with

straight and swivel / lock casters which make moving your QuietCool 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 QuietCool 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).

2.0 How Evaporative Cooling Works
Keeping in mind that regular fans only circulate same temperature air ­same humidity – your QuietCool 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 QuietCool was engineered efficient to evaporate perspiration and sweat
from employees to keep them cooler.

3.0 Unpacking your new QuietCool unit

Note: Carefully examine your QuietCool shipping carton for damage
before opening. If your carton is damaged – notify the shipper immediately!

Your QC18” unit was shipped strapped a wooden pallet inside a cardboard box.
First remove the straps then you may open the cardboard box. Your QuietCool
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 QuietCool unit.
Roll your QuietCool unit to a level surface and lock the swivel casters to prevent
accidental movement.
