To  enjoy the benefits of a properly humidified environment,
periodic cleaning is necessary to control both water and
household impurities. Film or scum, which can contain bacteria
or fungi, may appear on the water surface, the sides, or bottom
of your humidifier. A crusty deposit or scale may also appear
and is composed of minerals that have settled out of the water. 

To improve the efficiency of your humidifier, and to reduce the
possibility of a health hazard, it is recommended that you take
the following precautions:

•  Follow the manufacturer’s recommended cleaning and

maintenance instructions below and on the next page.

•  The amount of minerals and other impurities in a water

source can vary greatly, therefore, the frequency of
cleaning the unit also varies. 

•  During the heating season, check for film or scale build-up

in the unit, or any moving part. Establish a proper cleaning
schedule to ensure the efficiency of the humidifier.

•  An algaecide, such as a humidifier cleaning tablet or

bacteriostatic liquid/powder, can be used to combat algae
build-up, should it become evident.

•  At the end of the winter humidification season, drain and

thoroughly clean your humidifier as part of the summer
shutdown.

Like your heating system and air conditioning unit, periodic
maintenance and cleaning are required to ensure the safe and
efficient operation of your humidifier. Due to the operation
cycle of the furnace and humidifier, it may require 2 to 5 days
to reach the proper humidification level.

Before cleaning or
servicing this unit, it is
recommended that
the unit be
disconnected from
any electrical supply
outlet.
