SEQUENCE FOR MOUNTING THE APRILAIRE ® ENERGY
RECOVERY VENTILATOR TO CONCRETE WALL
INSTALLATION – NEW HOME
A. LOCATION
• It is recommended that the Model 8100 Aprilaire Energy
Recovery Ventilator be mounted in a conditioned
space. If the unit is mounted in an area where the tem-
perature may drop below 32°F (0°C) or exceed 100°F
(38°C), ALL DUCTWORK in the unconditioned space
MUST BE INSULATED.
• The recommended mounting location is on the base-
ment foundation wall, or a stud wall with easy access
to the furnace. This will minimize sound level and
shorten the length of duct runs and elbows required.
Unit may be mounted to basement ceiling joists if
desired.
NOTE: If the home has engineered ceiling "I" beam wood
trusses in the basement, the unit must be installed on the
wall. If that's not possible, the installation procedure must
be approved by a qualified builder before installation.
• Mounting on a utility or laundry room wall, any heated
space or where the temperature is kept above 32°F
(0°C, i.e. in a closet) is also acceptable.
• If possible, do not locate the unit directly under bed-
rooms, This unit is designed for quiet operation, but with
any blower system there is some sound generated.

B. GENERAL MOUNTING
WARNING: To avoid serious injury, do not mount unit
with access door facing down. Unit must be mounted
in an upright position.
• The unit must be mounted with the mounting kit provided
on the wall or suspended from the ceiling joists.
• For scheduled maintenance or service, the unit must be
mounted in a position which allows easy access to all
duct connections, electrical components and all interior
components.
• A minimum of 36" opening clearance is recommended
to ensure that the access door can be safely removed
for easy access to all interior components for mainte-
nance and service.
C. MOUNTING THE UNIT
To reduce the unit weight, remove the access door, filters
and EnergyMax Transfer Core. Lift only at the corners of
the core to avoid damage.
Determine whether unit is to be wall or ceiling mounted.
Brackets will be attached according to Figure 2A below.

lower right corner. Carefully lift unit up
and hook the hanging “hook” bracket
behind the hanging pin previously
installed on the left side of the mounting
