How Your Humidifier Works

Your new MoistAIR®Evaporative
humidifier is designed to satisfy home
humidity requirements through the
principle of evaporation of water in
the air.

Once the filter becomes saturated, air is
drawn in, passes through the filter and
moisture is absorbed into the air.
All evaporation occurs in the humidifier
so any residue remains in the filter.
This natural process of evaporation
virtually eliminates white dust.

CAUTION: To reduce the risk of
injury, fire or damage to humidifier,
use only cleaners specifically
recommended for humidifiers.
Never use flammable, combustible
or poisonous materials to clean your
humidifier.

To reduce the risk of scalds and
damage to humidifier, never put hot
water in humidifier.

Step 1. Getting Your Humidifier Up and Running

Assembly

Remove casters, water bottle, housing
assembly, and filter from the box and
reverse the base. Press casters into the
bottom of the base manually. Do not use
tools. Set the base upright.

Replace the filter, housing assembly and
bottle (See “Replacement and Care of
Filters”, page 11 for reference).

Step 2. Location and Electrical Hook Up

WARNING: For your own safety, do

not use humidifier if any parts are
damaged or missing.

Selecting A Location

Place humidifier on a flat level surface,
take extra care in leveling when placing
the unit on carpet. Position the humidifier
where the most humidity is needed or
where the most air will be circulated
throughout the house such as near a
cold air return.

Moist air (humidity) produced will
disperse into the whole house, but the
area closest to the unit will have the
highest humidity. If the unit is positioned
close to a window, condensation may
form on the window pane. If this occurs
the unit should be repositioned in another
location.

NOTE: Due to release of cool, moist air
from humidifier, it is best to direct air
away from thermostat and hot air
registers and to position humidifier next
to an inside wall. Unit should not be
placed where cold air from outside walls
or warm air from a hot air register blows
directly on it.

Positioning The Unit

The humidifier should be positioned with
the back (cord exit side) and left side, at
least 2 inches(5cm) away from the wall.
Air needs to enter through all of the
louvres in the housing assembly in order
for the humidifier to operate at peak
efficiency.

NOTE: Be sure that the humidistat, which
is located on the power cord, is free from
obstruction and away from any hot air
source.

Electrical Hook-Up

Locate nearest 120V A.C. wall socket in
the location desired, preferably on inside
wall. With the humidifier in the desired
location, route the electrical cord safely
so no one will trip or upset the humidifier.
Plug in the electrical cord.

WARNING: To reduce the risk of fire
or shock hazard, humidifier should
be plugged into a 120V A.C. outlet.
Do not use extension cords.

To reduce the risk of electrical shock,
this humidifier has a polarized plug (one
blade is wider than the other). This plug
will fit in a polarized outlet only one way.

If the plug does not fit fully in the outlet,
reverse plug. If it still does not fit, contact
a qualified electrician to install the proper
outlet. Do not change the plug in any
way.

Step 3. Water Fill

WARNING: To reduce the risk of fire

or shock hazard, do not pour or spill
water into control or motor area.
If controls get wet, let them dry
completely and have unit checked by
authorized service personnel before
plugging in.

After the humidifier is positioned where it
will be operating you are ready to fill the
humidifier. The bottle lifts straight up and
away from the base. Take care not to
bump or damage fill valve assembly on
the bottom of the bottle.

Remove the side fill cap and fill with
water. Replace cap and twist by hand
until secure. Hold the bottle upright over
the sink. Press up on the valve plunger
for one second to release a small amount
of water. If you hear air bubbles or see
leaks around the side fill cap or Spring
Valve Assembly, retighten and recheck.

CAUTION: Use only EPA Registered
Bacteriostat. Under no circumstances
should you use water treatment
products designed for Roto belt or
Ultrasonic humidifiers.

Place the water bottle back into the
humidifier base. When positioned
properly, the plunger will open and the
water will flow into the base. The base
will hold the entire contents of the water
bottle. Once the bottle is empty, remove it
and repeat the filling process. The
humidifier is now filled to capacity. To
benefit from less frequent filling let the
humidifier exhaust both the water from
the bottle and the base before filling.

Step 4. Operating the Controls

Where you set your desired humidity
levels depends on your personal comfort
level, outside temperature and inside
temperature. A starting set point of 30% ­40% ROOM humidity is recommended
but there may be conditions that require
a different setting.

IMPORTANT: Water damage may
result if condensation starts to form
on windows or walls. Humidity SET
point should be lowered until
condensation no longer forms. We
recommend room humidity levels do
not exceed 50%.

To Operate the Controls

Digital Display

Press the power button once to
display the digital readout*. Initially there
is a slight delay while the electronics
calibrate.

Two bars (- -) flash during this time.
Once calibration is complete a ROOM
humidity reading between 20% - 95% will
be displayed. A flashing 20 display
indicates that the room humidity is less
than 20%.

NOTE: The default settings at initial
startup are ULTRA QUIET fan speed and
65% SET humidity. After desired settings
are selected by the user, they remain as
long as the unit remains plugged in and
there is no power interruption. If the unit
is unplugged the original default settings
are employed.

Operating the Controls (contʼd.)

Speed Button

This humidifier is equipped with a
3-speed fan control. Each push of the
speed button advances the mode through
the settings of HIGH, MEDIUM, ULTRA
QUIET, and AUTO. The selected setting
is displayed on the digital readout. The
higher the setting, the faster water is
evaporated and released into the air.
ULTRA QUIET is the quietest setting and
is provided for conditions that do not
require a rapid evaporation rate.

How Auto Control Works

The AUTO setting allows the humidifier to
manage its speed range to maintain your
desired humidity setting. It will
automatically cycle to the most efficient
speed to achieve the desired humidity.
Here is how the fan will operate:

• HIGH speed if room humidity is 10% or

greater RH (Relative Humidity) below
the SET point.

• MEDIUM speed if room humidity is
10 - 5% RH below the SET point.

• ULTRA QUIET speed if room humidity
is 5% or less RH below the SET point.

If the room humidity is not increasing at
the current fan speed during a 15 minute
period, the fan speed increases to the
next higher speed until the humidity SET
point is reached.

NOTE: The humidifier may run on HIGH
for an extended period of time if the
actual room humidity is extremely low.

Humidity Control

These buttons allow you to adjust the
humidity to suit your needs. This
humidifier will automatically cycle on and
off as required to maintain the selected
setting. Press the humidity buttons
to cycle the SET humidity readout in 5%
increments between 25% and 65% RH.
Once you have set the desired humidity,
after 5 seconds the readout will change
to the actual room humidity.

NOTE: When the ROOM humidity is
displayed, pressing the set humidity
buttons once will display the current SET
point. To increase or decrease the current
SET point, press either the “+” or “-”
button until the desired SET point is
reached.

A SET point of 65% RH operates the
humidifier continuously regardless of the
ROOM reading. The humidistat that
senses the readings is located on the
power cord. Insure that it is free from
obstruction.

Using Your Humidifier

Refill Light

For maximum run time both the bottle
and the base should be filled. When both
the bottle and the base are empty the red
REFILL light will flash, informing
additional water is required. Also at this
time the unit will automatically switch into

DRY OUT and continue to run on ULTRA
QUIET speed for a 2 hour period. The

message DRY OUT will appear on the
digital display and the fan speed will
switch to ULTRA QUIET speed.

NOTE: During this time the room
humidity level will continue to be
monitored and the humidifier will cycle
the fan on and off until the filter is
completely dry. The fan will shut off
leaving you with a dry humidifier that is
less prone to mold and mildew growth.
If DRY OUT is not desired, refill the
humidifier with water.

NOTE: Once the dry out cycle is
complete, the fan will shut off and the
REFILL light will continue to flash. The
humidifier will automatically start again
when it is refilled.

Check Filter

The ability of any humidifier to efficiently
supply humidity output relies heavily on the
condition of the filter. As the filter loads with
impurities it gradually loses its wicking
capability. When this happens, moisture
output is reduced and the humidifier has to
work longer to satisfy the selected setting.
This humidifier has a check filter reminder
timed to appear after 720 hours of
operation. When the CK FILTER message
is displayed, disconnect the power cord
and check the condition of the filter.
If a build-up of deposits or severe
discolouration is evident replace the
filter to restore maximum efficiency.
The CK FILTER message is reset when
the humidifier is plugged back in.

Using Your Humidifier (contʼd.)

Humidistat

The humidistat located on the power cord
senses the percentage of humidity in the
air. It causes the humidifier to cycle on
and off to maintain the selected humidity

SET point. The fan will turn on if the
ROOM reading falls 3% below the SET

point and will continue to run the
humidifier until a reading of 1% above the
SET point is achieved. The fan will turn
off until the ROOM reading falls 3%
below the SET point again.

NOTE: Be sure that the humidistat, which
is located on the power cord, is free from
obstruction and away from any hot air
source.
