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%

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

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

EnviroCool Installation Instructions
Safety Rules
!
1. Read instructions carefully.
2. Electrical hook up should be done by a qualied electrician. All electrical wiring must conform to
local code standards.
!
WARNING:
To reduce the risk of electric shock, always disconnect power and unplug pump motorbefore
installation or performing maintenance Make sure EnviroCool cabinet is properly grounded to a
suitable ground connection for maximum safety.
!
Avoid Backdrafts
Care should be taken to avoid backdrafting combustion appliances that are installed in the conditioned
space. It is strongly recommended that combustion appliances NOT be installed in such a manner that
they use room air for for combustion. The whole house fans is capable of pulling large quantities of air
from the home and particulary if not enough windows are open, may easily backdraft a water heater
located inside a louvered closet door
Select a tentative location. You should consider all the clearances that you
will need by observing both inside and outside before making a nal
selection. Make sure from the outside wall that the unit is high enough that
the bottom will not touch the ground and the top won’t stick above the
window (if placed under window). Usually 36 inches is needed from
window to ground level for horizontal.

circuit and then cut the wire in two at the center of the opening. Chisel
a notch in the studs at the sides of the wire opening to bring the wire to the
outside, so that the wire is ush with the face of the studs or create new
outlets on each side of unit and run new wire to re-feed circuit.

If no electric wire is found in the opening, bring a wire from the nearest wall
receptacle on the inside wall into the opening and route to the outside by
chiseling a notch in the stud as described above.
Cut and screw in place ¼” coroplast blocks top and bottom. The coroplast
11.
should be wide enough to cover the opening as well as the thickness of the
inside drywall edge plus the outside wall edge. The bottom coroplast
blocks should slope very slightly downhill toward the outside. Cover the
sides of the opening with coroplast and tape the studs with duct tape so
that no bare wood is visible. Apply duct tape completely around the
opening on both the inside and outside. Install the duct tape by allowing ½
of the width of the tape to be on the coroplast in the opening and the other
half of the tape is then folded over onto the inside and outside walls.
Locate and fasten the main frame to the outer wall using (3) #10 x 2” screws

on each side that will go through the exterior wall and into each side stud.
Where electric wire is protruding, cut a notch in the mainframe using tin
snips to eliminate contact with the mainframe. Prior to fastening the
mainframe to the wall, run a large bead of window and door caulk around
the top and sides of the back of the mainframe to obtain a good seal to the
exterior wall. After fastening the mainframe in place, apply an additional
small bead of caulk around the top and sides of the mainframe to wall joint.
13.
Make electrical connections at inside of mainframe at the junction box so
that the plug receptacle is hot. Then turn power back on.
Bring ¼” poly waterline from nearest outside source such as a hose bib, and
14.
connect to bottom left corner of mainframe. Fasten poly pipe to wall with
clips to maintain a neat, straight installation so that there are no places for
poly pipe to become snagged and damaged.

QuietCool fan installation instructions

Now that you have determined in which areas you would like to install your
QuietCool fans, it’s time to go into your attic to mark the exact location for each
install from above.
When you nd a location, move the insulation away to get a clear view. Make
2.
sure the template ts between the framing, and there are no other
obstructions in your chosen location. If there is a reason you can not use the
exact spot, nd a location in the area that does work. Place the template on
the spot and mark it by making a hole at each corner with a screwdriver.
Repeat these steps at each location
3.
Once all locations are marked, move the insulation away and return below to
the house. It’s now time to cut the holes at each air intake location.
Place the cut-out template at each location making sure you have 2 inches of
4.
clearance all the way around it. The grill that will be installed later is larger than
the template. While holding the template in place, mark around it with a
pencil. Using a drywall saw, or similar device, cut out the hole.
Repeat these steps at each location
Open and unpack each QuietCool fans. Make sure all parts are present. Most of
5.
the system comes pre-assembled. The main assembly should be put up in the
attic through the crawl hole and moved into position near the ceiling cutout
hole.
It’s now time to hang the motor heads from the rafters. Your goal is to hang
6.
the motor head as far from the hole in the ceiling as possible, while making
sure the ceiling box and duct will easily reach the hole.
Using the metal strapping attached to the motor head assembly, and the gray
7.
deck screws provided, hang the motor head from the rafters. Make sure the
motor head is fairly level side to side. Again, make sure the ducting will reach
the ceiling cut out with a little slack. You will need to secure the ducting later
in these instructions.

Once all of the QuietCool fans are hung, it’s time to go below and install the
10.
ceiling box and ceiling grill at each intake location.
Look through the hole and make sure there are no kinks or twists in the
11.
ducting. Pull the ceiling box down through the hole in the ceiling. While
holding it in place, install a 1-3/8” drywall screw through the drywall into the
ange of the ceiling box on each side to temporarily hold the box in place.
Remove ceiling grill and screws from its packaging. Center the grill over the
ceiling box. Install the grill with the white screws provided by screwing
through the ange of the ceiling box. Some ceiling surfaces are uneven and
may cause a small gap to be present. This can easily be caulked later if
excessive.

Return to the attic and go to each location. Using the nylon straps and the pan

entire assembly. Replace any insulation that was removed.
