QuietCool Portable Evaporative Cooler 

 

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 in a plastic sleeve. Look for a sample Evap-O-Matic tablet. 

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 

spray water temporarily.  

 

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 QC48” 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 QuietCool must now be lifted off the wooden skid. 

 

4.0  Set-up your QuietCool unit.  

Roll your QuietCool unit to a level surface and lock the swivel casters to prevent  

accidental movement.  

 

 

 

Electrical cord for 120V, 20Amp connection. 
Note: Standard ¾” water connection for 
utility water source under 60 p.s.i.
