When you have decided where and how to install the unit:
Frame in the opening yourself:
First, using appropriately sized lumber (e.g. 2" × 6", 2" × 8", etc.) cut to fit, frame in a rough opening from the
living
space into the attic as shown below. Cut out the drywall inside of the framing to create the rough opening.
Best method is to drill holes in the inside corners of the created framing and then saw out the piece from the
living space. Clean-up can be made much easier by using a tarp and/or box to catch the falling debris.
To ensure that all air drawn in by the fan will be from inside the house, use a good quality latex caulk to seal all
wood-to-wood and wood-to-metal joints to create an air-tight enclosure.

For HV2800
Kaze Direct Mount or HV2800D Venti Ducted Whole House Fan
NOTE: place the actuator on the fan side (shortest route for the actuator wire from the fan (ducted unit only))
Press the (yellow) Clutch on the actuator to open the door fully. Apply a bead of caulk around the base of the unit
and install it using the supplied screws. Mounting Screws only need to “hold” the unit in place, do not over-
tighten which may distort the door unit. See image below.
