Dear Owner:
Congratulations on your choice ofaTrion humidifier. Your family can
now lookforward to breathing more comfortable
air, winter afterwinter.
We know, because we have been engaged in the design and
production ofhumidification equipmentfor home and industryfor over
50 years. Today, as then, we are committed to providing advanced
products that improve the quality of the air you breathe.
The following information will familiarize you with the operation of
your new humidifier and provide helpful tips on how to obtain
maximum performance from your unit.
INTRODUCTION
All humidifiers, airconditioners, refrigerators and dehumidifiers require
periodic cleaning and maintenance to insure efficient and safe
operation.
The benefits of a properly humidified environment (35-50%) are
enjoyed by everyone living
in such an comfortable environment.
These benefits include both personal comfort and the preservation
offurniture, draperies, carpets, woodenfloors and cabinets, paintings,
pianos, etc. -all hygroscopic materials. A hygroscopic material is
onethat has the abilitytogive up or absorb moisture. Your home will
be more comfortable at a lower temperature
(Le.: 680 F) at 30-40%
Relative Humidity (RH) than at 71 °to72° Fwithoutcontrolled humidity.
Since every degree oftemperature setback represents about 3% of
yourheating costs, this can represent a possible 9-12% annual saving.
During the heating season, cold air is brought into the house and
heated. When heated, this air dries out and greatly increases its
capacity to hold more moisture. By using a humidifier, we provide a
source of water to satisfy this increased moisture holding capability,
ratherthan having itdrawn from our bodysurface and the surrounding
hygroscopic furnishings
in the home.

With the energy crisis of the mid-70's, home builders and owners
have become more conscious of energy conservation.
To conserve
energy,
home~ have become tighter in construction to provide less
infiltration of cold outside air and less exhaust of heated inside air.
This has been accomplished by using more insulation, tighter storm
windows, weather stripping and being more personally conscious of
tightly closing doors and windows in general.
Thistighterenvironment in which we now live is also a more stagnant
environment and has brought about an increasing concern about
"IndoorAirQuality." The air in the home is notbeing allowedto change .
as frequently.
As stated, a properly main"tained and efficiently operating humidifier
is a source ofimproved IndoorAir Qualityand personal comfort. The
necessity to clean your humidifier is substantially the result of
impurities coming in through your water supply which feeds; the
humidifier. Otherhousehold dust, containing biological and microbial
contaminants, finds itsway intothe airhandling system and ultimately,
the humidifier.
The humidifier is not the source ofthese impurities.
To enjoy the benefits of a properly humidified environment, periodic
cleaning is necessaryto control both waterand 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 ofthe water.
2

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.
The amount of minerals and other impurities
in a water source
can vary greatly and hence, the frequency of cleaning also
varies.
During the heating season, check for film or scale build-up on
• a monthly basis and establish a proper cleaning schedule.
•
Do not allow film or scale to build up on the unit, evaporator
pad, or any moving part and reduce the efficiency ofthe
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 ofthe winter humidification season, drain and
thoroughly clean your humidifier as part ofthe summer shut
down.
Like your heating system and air conditioning unit, periodic
maintenanceand cleaning are required to ensure the safe and efficient
operation of your humidifier. This cleaning necessity is also likened
to weekly house cleanings and periodic maintenance of your
automobile for its safe and efficient operation.

OPERATION OF HUMIDIFIER
This 447-1/447-C1 humidifier operates on the silent principle of
evaporation. When your unit is operating properly, you may observe
the drum turning freely by looking through the observation window.
Evaporation takes place as the air passes through the moistened
evaporator pad held
in place by the specially engineered rotating
drum assembly. Operation is completely automatic, working
in
conjunction with the heating system blower. A portion ofthe warm air
is bypassed through the humidifier
for quiet and economical
humidification ofthe air
in your home. The humidifier is designed for
use with either hard or softened water.
Set the humidistat in the recommended range of 30-50% relative
humidity for automatic humidity control during the heating season
(a
lower setting may be used to control condensation on single pane
windows). During the first heating season, check the mineral build-
up every month to establish the propercleaning schedule. Clean the
unit at the end ofeach heating season or whenever mineral deposits
appear to clog the openings in the evaporator pad
You can easily check your humidifier to be sure it is in working
condition. Simply turn the humidistat to a higher setting and look
through the observation window
(a flashlight may be needed). Ifthe
unit is working properly, the evaporator pad will be rotating. Be sure
to set the humidistat back to the desired level.

MAINTENANCE INSTRUCTIONS
Periodic cleaning is required for the efficient and safe operation of
this humidifier. Inspect the humidifier approximately once a month
for mineral and algae growth. Algae maydevelop insidethe humidifier
if certain conditions exist in the water supplying the unit. Algae is a
slimy substance which can be green, brown orwhite. It is advisable
to add an algaecide to the water on a weekly basis. This algaecide
can be 10 drops of bleach or Trion humidifier tablets purchased
through your local Trion dealer. Periodic cleaning and removal of
accumulated mineral deposits and algae growth will be the only
maintenance this unit requires. The frequency of this maintenance
will depend on the mineral content, or hardness,
of the water being
supplied to the humidifier.
To inspect the unit:
1. Turn the power to the furnace OFF.
