The type and size of home is the main factor that determines how much air should be moved through it
which give the necessary air exchanges per hour to provide sucient cooling.
Rules of thumb have been developed to arrive at satisfactory results for most conditions.
1. For newly or recently constructed homes that have tight envelopes and are insulated to recent high
2. For homes in cool coastal climates, the CFM’s can be reduced by 20%
3. For homes in hot desert climates, the CFM’s should be increased by 25%
4. For poorly insulated homes and homes that are not well sealed, the CFM’s should be increased by
5. For homes with high or vaulted ceilings, the CFM’s should be increased by 10%
6. The model number of the QuietCool fan designates its CFM performance. For example, a QuietCool

the moving air from the EnviroCool to each QuietCool fan will be cooled eectively. Those rooms not
in the pathway may not achieve satisfactory comfort levels. To overcome this problem, additional
EnviroCools can be added to these rooms if required.
(Example: Increase from 4 to 5 fans)
LAYOUT
Each home needs to be studied and planned so that the placement of QuietCool fans and EnviroCools
will achieve the optimum performance. The following rules will be helpful.
1. Each EnviroCool must be installed in an exterior wall. It should be on the lower oor of a multi-
home.
2. The best layout for the EnviroCool is to place it in the room
level temperatures and are as far removed as possible from the location of the fans.

3.
roof directly above it.
4. When QuietCool fans are mounted in an attic, it must be ascertained that the attic has (or is
of having) vents to the outside in the amount of one square foot for each 750 CFM of fan
5. In single story houses, the fan (or fans) should be located as far as possible from the EnviroCool
location. It is recommended that each bedroom and oce have a QC4500 installed in a master bath. In multi story houses, the fans should be placed in upper story
6. The fans should generally be placed near the center of each room, to allow cooling by drawing air
from the Enviro
7. The ideal arrangement is to have either an EnviroC
pathway of air moving from the EnviroC
ool, or from an open window when outside air is cool.
