All QuietCool 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  QuietCool  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  QuietCool  (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). If you have purchased our optional QR60 gallon reservoir tank  – simply attach the garden hose from 

the tank to the cooler. 

Note:

 Do not connect to water source exceeding 60 p.s.i. – this can cause damage to your QuietCool. 

 

5.0  Operating procedures 

Back  your  QuietCool  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  QuietCool  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 QuietCool cooling pads are saturated – then, you are ready to turn fan on high and begin to feel the cooling effect from 

your new QuietCool. 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 ½ Evap-O-Matic Chemical Water 

Treatment tablet and refill with fresh water. (Simply remove a cooling pad to place tablet inside of water reservoir).
