YPICAL NSTALLATIONS
Use the following illustrations as guidelines to help you decide on how the unit will be installed.
All the units should be hung from the joists.
If required, bathroom fans and a range hood may be used to exhaust stale air. Also, for homes with more than one level, we recommend
one exhaust register at the highest level.
There are 3 installation methods: Fully ducted, Central Draw Point and Simplified Installation.
NOTE: An electrical outlet has to be available within 3 feet of the unit.

Stale air coming from the registers located at the highest level of the
house is exhausted outdoors. Fresh air from outdoors is filtered and
supplied by the register located in the lowest liveable level.
Homes with more than one level require at least one exhaust register at
the highest level.

Stale air coming from the registers located at the highest level of the
house is exhausted outdoors. Fresh air from outdoors is filtered and
supplied to the return (plenum) or the supply duct of the forced air unit.
See figure at right.
For this type of installation, it is not essential that the forced air system
blower runs when the unit is in operation, but we recommend it.
NOTE: Home with multiple forced air systems should have one unit on
each system.
