Installation Location With Humidifier
A humidifier should be installed in the furnace warm
air duct. However, it may be installed in the return duct
without causing problems to the Air Cleaner. Care must
be taken to ensure that the humidifier does not leak, as
this may cause arcing and a mineral deposit to build up
on the collecting cells.
An atomizing type humidifier should be installed
downstream from the Air Cleaner. If the atomizing type
humidifier is installed upstream, high humidity, salts and
minerals may decrease the efficiency of the collecting
cells and cause service problems.
If the atomizing type humidifier must be installed
upstream, the following precautions should be taken:
1. Atomizing type humidifier must be installed as far
from the Air Cleaner as possible.
2. Collecting cells must be washed frequently to prevent
a mineral deposit build-up.
Installation Location With Air Conditioner
Whenever possible, the Air Cleaner should be
installed upstream of the cooling coil. This location will
clean the air before it reaches the evaporator coil.
