SAFETY INSTRUCTIONS
Read the Safety and Installation Instructions carefully. They will help insure a correct and
SAFE installation of the Aprilaire
®
Energy Recovery Ventilator.
WARNINGS:
1. 120 Volts may cause serious injury from electrical shock. Sudden operation may cause serious injury
from moving parts. Leave power disconnected until installation is completed.
2. The fresh air intake must be mounted in a location removed from sources of dangerous toxic gases.
Examples of such sources, but not limited to these sources, include the exhausts from condensing
furnaces, condensing water heaters and vented space heaters. These exhausts contain toxic
substances that can be harmful to humans.
The fresh air intake should be installed a minimum of 10 feet from any exhaust vent.
3. Connection with existing air exhaust sources may cause toxic conditions in the living area. The
Aprilaire ducting must be separate from sources such as dryer vents, water heater, furnace flues,
gas appliance flues or bathroom and kitchen exhausts.
4. Unit weight and dropping may cause personal injury or equipment damage. Handle with care and
follow installation instructions.
5. WARNING: To avoid serious injury, do not mount unit with access door facing down.
Unit must be mounted in an upright position.
6. Sharp edges may cause serious injury from cuts. Wear protective gloves and handle with care.
7. Excess negative or positive pressure may cause health problems or structural damage. Air flow
must be balanced after installation.
8. Insufficient combustion air may cause toxic conditions. The Energy Recovery Ventilator must not
exhaust air from an enclosed room with combustion appliances.
9. Installation must conform to all applicable codes.
10. The fresh air duct from outside the Energy Recovery Ventilator and the stale air duct from the
Energy Recovery Ventilator to the outside must be fully insulated. The fresh air duct connection
to the unit must also be completely insulated. This is to prevent condensation from forming on
the ductwork.
NOTE: This manual does not express or imply any warranty conditions. See Owner’s Manual for further information.

• All the same mounting, locating, ducting and electrical
hook-up guidelines apply for retrofitting as they do in
new home installations.

INSTALLATION INTO EXISTING HOME (RETROFITTING)
INSTALLATION IN HOMES WITHOUT FORCED AIR
(HYDRONIC OR ELECTRIC BASEBOARD)
All the same mounting, locating, ducting and electrical
connection procedures apply to this situation as they do
in new home construction, except for the following
changes:
• The Aprilaire Energy Recovery Ventilator can be properly
installed into a home with no forced air ducts by
installing fresh air supply ducts to various parts of the
house where fresh air is needed.
• It is recommended that no more than 3 fresh air supply
ducts be used to assure an adequate air flow.
The total free Area of supply grilles should not be less
than 75 square inches. Use of less than the minimum
free area may result in greater than the normal air
movement noise.
• Three (3) supply ducts require a minimum of 25 square
inches free area each. Two (2) supply ducts require a
minimum of 40 square inches free area each. One (1)
supply duct requires a minimum of 75 square inches
free area.
• Do not place a supply outlet in the same room or in the
vicinity of the stale air return from the house.
• Try to place the supply of fresh air to the house outlet,
or outlets, in a hall or foyer to avoid drafts and possible
blower noise in occupied areas.
• Try to keep all supply duct runs short, straight and
equal in length.
SYSTEM START-UP
1. Make sure the EnergyMax Transfer Core and filters
are installed correctly.
2. Double check all ductwork connections to be sure they
are installed and sealed properly.
3. Check to be sure all tools are removed from interior and
exterior of housing.
4. Make sure the blower motor and duct connections are
not obstructed.
