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, find 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 find the exact location for your
damper box and grille to ensure the duct will fit 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 fit between the fan location and the damper box
location. The duct is 9’ long.
