1. The fan housing will fir either 16” or 24” on center
framing. Cut two pieces of 2x stock (2x6 or 2x8 etc.) of
the same dimension as the existing joists. Add these
pieces of framing to form a box between the joists
(Figure 1).
TIP: When the HV3400 is to be installed in a location
with low ceilings, some homeowners find that building
a box out of 2x10s or a similar material will raise the
HV3400 to a position where the sound level will be
reduced but the efficiency of the fans will not be
diminished. This box should not exceed 24” in height.
2. Cut a hole in the ceiling under where the HV3400 will
be installed. The hole should be no larger than 14
½”x22 ½”. This will allow for the grille to cover the
exposed edges. The suggested method for making the
proper sized hole in the ceiling is; cut a pilot hole under
where the fan will be installed (Figure 2). From above,
using a saw, cut along the inside edge of the
framework removing the ceiling panel and any
strapping within the framework. Do not damage
electrical wiring or other hidden utilities.
3. Install a foam weather stripping or other flexible
material (not supplied) on top of the joists and added
framing. This will serve to seal between the housing
and the framing as well as dampen vibrations. Check
the joint between the and the 2x stock. Some types of
ceilings are spaced away from the joists. Any gap
between the 2x’s and the ceiling should be sealed
prior to final installation. (Figure 3) Use a low expansion
spray foam sealant (not supplied).
4. Set the HV3400 lower housing onto the framing. The
lower housing will fit into the box with the mounting
flanges overlapping the framing. DO NOT DRAG THE
HV3400 INTO POSITION AS THIS MAY SEVERLY DAMAGE
IT.
5. Set the HV3400 upper housing at an angle on top of
the lower housing, orienting the upper housing so that
the fan motor connections are in the same corner
(Figure 4). Push the fan electrical connection into the
fan electrical feed. The connecters are ‘keyed’ so
they will only connect in one way (Figure 5).
You will need the following items: two pieces of 2x stock to
match your existing framing, a saw to cut the hole in the
ceiling, a hammer or screw gun to attach the grille, weather
strip material and low expansion spray foam sealant.

Hardwiring the unit to controls
using YELLOW, BLACK, and BLUE
wires will allow for additional,
manual operation. Use of
controls will override remote
control functions.
Recommended controls are
SPST switches and/or non-digital
spring wound timers. Use of
other controls will void the
warranty.
*1. SPST Switch (shown) and/or
mechanical spring wound timer.
These devices are wired directly to
the leads found in the silver utility
box. DO NOT CONNECT TO

Operating your HV3400
Important- Be sure at least one window is open when the fan
is operating. The HV3400 is controlled by the handheld remote
transmitter. The transmitter has four buttons; ON/OFF is button
A. HI/LO is button B and controls the speed of the fan. Buttons
C & D are not used. See the wiring section below for more
details.
6. Rotate the upper housing until it lines up with the lower
housing. Make sure the edges of the two housings mate
all the way around the HV3400 (figure 6) and then pull the
black attachment handles down over their attachment
posts (Figure 7).
7. If desired, secure the HV3400 to the top of the joists.
8. Plug the connector from the HV3400 into the Control
Box. Plug the Control Box into an unswitched, grounded
receptacle.
9. Install the ceiling grille (screws provided).
10. Check the unit for proper Operation.
