2. TYPICAL INSTALLATIONS
NOTE: Installation may vary according to the model number and the position (normal or reverse) in wich the unit is installed.
There are three common installation methods.
2.1 F D S
ULLY UCTED YSTEM
(Primarily for homes with radiant hot water or electric baseboard heating.
See illustration at right.)
Moist, stale air is exhausted from the high humidity areas in the home, such as
bathrooms, kitchen and laundry room.
Fresh air is supplied to bedrooms and principal living areas.
If required, bathroom fans and a range hood may be used to better exhaust stale
air.
Homes with more than one level require at least one exhaust register at the
highest level.
2.2 E D S
XHAUST UCTED YSTEM
(For homes with forced air heating. See illustration at right.)
Moist, stale air is exhausted from the high humidity areas in the home, such as
bathrooms, kitchen and laundry room. Fresh air is supplied to the cold air return
or the supply duct of the furnace. If required, bathroom fans and a range hood
may be used to better exhaust stale air.
Homes with more than one level require at least one exhaust register at the
highest level.
NOTE: For this type of installation, it is not essential that the furnace blower runs
when the unit is in operation, but we recommend it.
2.3 S (V V
IMPLIFIED OLUME
(For homes with forced air heating. See illustration at right.)
Fresh air and exhaust air flow through the furnace ducts, which simplifies the
installation.
The use of bathroom fans and a range hood is suggested to exhaust stale air.
NOTE: For this type of installation, the furnace blower must be running when
the unit is in operation.
