2. INSTALLATION
2.1 INSTALLING THE RM WHF-4.0
1. Determine in which area you would like to install your QuietCool Roof Mount Fan (see diagrams below)
IMPORTANT: After choosing the location where your roof mount fan will be installed, nd the
closest rafter to that location and determine if your roof has either 16” on center or 24” on center
rafter spacing. The above diagrams show what rafter spacing and roof joist spacing is required for
each installation type.
IMPORTANT: If you are installing the RM WHF-4.0-PL, skip to section 2.5 on pg. 9.
IMPORTANT: Before installing the RM WHF-4.0-DB, you will need to nd the exact location for your
damper box and grille to ensure the duct will t between the fan location and the damper box
location. Locate the ceiling studs and mark the location for the box to be installed. Minimum of 36”
clearance required. Make sure the duct will t between the fan location and the damper box
location. The duct is 9’ long.

2. From inside the attic, nd the center point between the two
roof rafters and mark it as the center of the fan hole. Partially
insert a screw into the center point mark.
NOTE: If you have a tile roof, you will need to move the
tiles out of the way before tracing and cutting. (See Figure
2.1A)
3. Go to the roof. Using the screw as a reference point and the
provided template, trace out the 22” diameter circle.
4. Use a reciprocating saw to cut out the traced hole pattern
from the roof decking. Remove the cut out decking material
from around the hole as needed. (See Figure 2.1B)
5. If you have a shingle roof, insert the reciprocating saw
sideways between the shingles and roof decking. Starting
at the 3 o’clock position of the fan hole, begin cutting in a
sweeping motion under the shingles, cutting through any
roong nails or staples. Continue cutting counterclockwise
around the fan hole until reaching the 9 o’clock position. Using
a roong knife, cut a 4 inch horizontal slit in the shingles at the
9 o’clock and 3 o’clock positions of the hole, allowing the fan’s
ashing to slide underneath the shingles.
6. Apply weatherproof material to the roof. (See Figure 2.1C)
7. Position the fan so that it is centered with the fan hole and
allow the power cord to hang freely from the bottom of the
fan unit. The power cord comes in 20 ft length.
(See Figure 2.1D)
NOTE: Power cord CANNOT be used outdoors.
8. Lifting the fan unit up at an angle, apply weatherproof caulking
to the bottom side of the fan unit. This will help keep the fan in
place and will seal nice and tight.
9. With all fan cables connected and hanging inside the fan hole,
slide the fan unit underneath the shingles until the fan reaches
the top of the hole. Secure the fan ashing to the roof. Finish
caulking around the fan and ashing it into the roof to make a
nice seal. (See Figure 2.1E)
10. If installing on a tile roof, cut tile appropriately and re-install
the tile to t snuggly around the fan housing. (See Figure
2.1F)

1. Once you have determined the location for both the fan and damper grille, use the supplied square
template to cut out your roong and ceiling material for the supplied Plenum Flash Mount and
damper grille.
2. Secure the Flash Mount to the roof. Finish caulking around the Flash Mount and ash it into the roof to
make a nice seal. Take the plenum box and slide the Flash Mount lip into the plenum box.
3. Make sure the plenum box sits ush to the roof. Using roong nails, fasten the plenum box to the roof
using the six tabs located around the plenum box.
4. Position the fan on it’s side allowing the RF Control Hub to hang in the circle fan hole in the plenum box.
Remove the power cord and RF Control Hub from the fan ex. Run the fan ex into the junction box on
the bottom oor of the plenum box. Remove junction box plate cover and tie wires together. Re-install the
plate cover.
5. Lifting the fan unit up at an angle, apply weatherproof caulking to the bottom side of the fan unit. This will
help keep the fan in place and will seal nice and tight.
6. Position the fan over the circle fan hole in the plenum box. Using the supplied self-tapping screws with
rubber-bonded washers, attach the fan unit to the plenum box. Be sure to caulk around the screw head.
IMPORTANT: If you have drywall on your ceiling, use the supplied template to cut out your grille hole.
If you have open ceiling rafters with no drywall, you will need to frame in the grille. (See Figure 2.5D)
7. Run your electrical piping or seal tight ex into the half inch knockout in the plenum box. From inside the
home, mount the RF Control Hub into the half inch knockout in the plenum box. Bring your electrical wires
into the backside of the RF Control Hub (See Figure 2.5B). Slide your lock nut over the wires and thread it
onto the 1/2” ex connector to secure the RF Control Hub to the plenum box. Bring the fan wires from the
harness inside the plenum box into the RF Control Hub (See Figure 2.5C).
8. Follow the wiring instructions on page 11 to wire your RF Control Hub to the power source.

4.2 FREQUENTLY ASKED QUESTIONS
WHAT DOES RF MEAN?
“RF” Stands for Radio Frequency.
HOW DOES RF WORK?
A small electronic device is used to transmit and/or receive radio signals between two devices. In an
embedded system, it often communicates with another device wirelessly. This wireless communication may
be accomplished through optical communication or through radio frequency (RF) communication.
WILL RF INTERFERE WITH OTHER DEVICES IN MY HOME?
The RF will not interfere with other wireless or RF devices in your house. It produces its own unique RF signal
that can only communicate with our RF Switch.
HOW MANY SWITCHES CAN YOU CONNECT TO A SINGLE HUB?
You can connect up to 20 switches to a single hub.
WILL MY NEIGHBOR BE ABLE TO CONTROL MY FAN IF THEY HAVE THE SAME
SET UP AS ME?
They will not because you need to physically activate the pairing process between the RF Switch and the
RF Hub.
WELCOME INSTALLATION WIRING OPERATION WARRANTY

1-888-QUIETCOOL
16
WHAT IS THE RANGE?
The RF Switch and RF Hub have a range restriction of 100ft.
WHAT HAPPENS IF I LOSE THE RF SWITCH?
If you lose or damage an RF Switch you will need to purchase another and re-pair the new one to the
RF Hub.
CAN YOU CONTROL MULTIPLE FANS WITH A SINGLE SWITCH?
No. You can only control one RF Hub per switch.
HOW LONG DO THE BATTERIES LAST?
Up-to one year.
WHY ARE ALL MY LIGHTS SOLID ON THE HUB AND NOTHING IS WORKING?
If you’re experiencing solid lights on the hub then it is an indication that your DIP switches are not in the
correct position. Disconnect power, adjust your DIP switches, and the only light that should be lit is your
RED power light.
HOW DO I CHANGE THE DIP SWITCH TO THE CORRECT SPEED OF MY FAN?
You will need to disconnect power, make your adjustment inside the hub, and then reconnect power.
CAN YOU CONNECT THE RF CONTROL TO A SMART HOME SYSTEM LIKE ALEXA,
GOOGLE HOME, OR APPLE HOMEKIT?
No, in the current conguration the RF Control cannot connect to a smart home system. There are
systems on the market that take RF signal and translate them to a smart home system, but they have
not been tested and may not work reliably.
4.3 WHEN TO RUN A QUIETCOOL WHOLE HOUSE FAN
Anytime it is cooler outside than the inside of your home, the system will work effectively. In the summer
this normally happens in the late afternoon to early evening, through to the next morning. We recommend
running your fan through the evening. If you have a multi-speed fan, you will get the best cooling effect
when you turn the fan on low after desired cooling occurs and let it run throughout the night.
QuietCool can also be used in the winter to heat your home during the day and exhuast the pollutants
inside your home.

QUIETCOOLSYSTEMS.COM
17
WELCOME INSTALLATION WIRING OPERATION WARRANTY
4.4 WHERE TO START COOLING THE HOME
We recommend cooling the area where you are going to be spending the most time for the next few
hours. For example, in most family situations, the early evening is spent in the kitchen or family room area.
Assuming this to be true, this is where you would want to start the cooling process.
Begin by opening a few windows in the area you are going to be spending your time and turn on all of
your QuietCool fans at once, for maximum cooling. The cooler air outside will immediately begin to create
a breeze in the home making you feel up to 10 degrees cooler, instantly. Opening windows too wide or
opening too many windows will lessen the cooling breeze you feel.
The breeze will ow through your home and make its way to each QuietCool you have in operation.
As it gets later in the evening, and even cooler outside, you can begin to open windows in other rooms of
your home, to prepare for bedtime. Then when it’s time for bed, you should close all the windows in your
main living space, but leave the windows in your occupied bedrooms open. This will provide each room with
a cool breeze as long as desired. If you are using an 8 hour timer, you can automate your fan and have it turn
off when you anticipate it being comfortable for sleeping. If you have a QuietCool installed in each bedroom
as we recommend, you can enjoy the breeze and your privacy with your door closed.
4.5 INDOOR AIR QUALITY
You will want to ventilate your home on a very regular basis. Many studies such as one from the
Environmental Protection Agency show that the air inside homes can be 2-5 times more polluted than
the air outside, even in the smoggiest of cities. Your QuietCool system can greatly reduce this problem
by bringing in fresh air and exhausting stale polluted air all year round.
If you have any trouble installing or operating your new QuietCool Whole House Fan, or for more tips
