Installation Into Existing Home (Retrofitting); Installation Into Homes Without Forced Air System; System Start Up - Aprilaire 8100 Owner's Manual

INSTALLATION INTO EXISTING HOME (RETROFITTING)

• All the same mounting, locating, ducting and electrical
hook-up guidelines apply for retrofitting as they do in
new home installations.
INSTALLATION IN HOMES WITHOUT FORCED AIR
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.
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.
(HYDRONIC OR ELECTRIC BASEBOARD)
SYSTEM START-UP
• 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.
