INTRODUCTION

Thank you for purchasing a Robitussin®Natural Cool Moisture™ Humidifier.

HO W D OE S IT W O RK ?

NATURAL COOL MOISTURE™ SYSTEM

Dry air is pulled through the Natural Cool Moisture™ system and a quiet fan blows out
invisible, moisture-balanced air. Unwanted minerals and bacteria from the water are
trapped inside the Natural Cool Moisture™ filter. When the unit is running you will not
see or feel a “mist”. You will know your humidifier is putting moisture into the air as you
watch the water level in your tank decrease throughout the day.

W H AT I S H E A LT H S H I E L D

Your Robitussin Natural Cool Moisture™ filter has been designed using new
HealthShield™* technology which prevents surface growth and migration of mold,
fungus and bacteria in the filter for its life - approximately one season. Keep in mind,
depending on your water quality, mineral deposits can still clog or discolor the filter,
affect its life and that of the humidifier.

Environmental Protection Agency (EPA).

Base

SET UP

NOTE: We recommend that the humidifier be disinfected prior to first use. Please see
CLEANING instructions.

• Select a firm, level, flat location - at least six inches (15 cm) from any wall for proper

air flow (Fig. 1). Place the humidifier on a water-resistant surface, as water can
damage furniture and some flooring.

The manufacturer will not accept responsibility for property damage caused by water
spillage.

FILLING

• Remove the water tank by grasping handle and pulling

straight up. Set aside (Fig. 1).

• Lift up on the motor housing to remove and set aside

(Fig. 2). Remove the Natural Cool Moisture™ filter
from the base before filling the unit with water. Soak
filter in a sink full of cool water to help reduce mineral
build up and place back in the humidifier while wet.
DO NOT SQUEEZE OR WRING OUT THE NATURAL
COOL MOISTURE™ FILTER. To help extend the life of
your filter repeat this step each time you fill your
humidifier.

• Turn the Water Tank upside down so that the Fill Cap is

facing up; unscrew the Fill Cap by turning it counter­clockwise and set aside.

•

Fill the Water Tank with COOL tap water (Fig. 3). Distilled
water is not necessary as the water is filtered by the
Natural Cool Moisture™ filter.
Doing so may damage the humidifier.

your room has reached a comfortable humidity level.

• At this point, slowly turn your Moisture Control knob
clockwise until the humidifier shuts off and the Desired
Humidity light comes on (Fig. 5).

• Now that your Moisture Control knob is set, the humidifier
will automatically turn back on when your room drops
below your comfort setting and will automatically turn off again when the setting is
reached.

WEEKLY CLEANING

We recommend cleaning the humidifier once a week, more often if you have hard water,
notice a build up of impurities or detect unpleasant odors.

PROLONGING THE LIFE OF THE FILTER AND
MAINTAINING A CLEAN HUMIDIFIER

NOTE:DO NOT ATTEMPT TO CLEAN THE NATURAL COOL MOISTURE™ FILTER WITH
ANY CHEMICAL SOLUTIONS, DOING SO WILL DAMAGE THE FILTER.

• HealthShield™ prevents the surface growth and migration of mold, fungus, algae, and
bacteria. It is normal for a filter to discolor from mineral build-up. This will vary
depending on water quality.

• DO NOT clean the filter using any chemical solution.

• If a Natural Cool Moisture™ filter appears to be clogged by hard water or mineral
deposits, soak it in a sink full of cool water for 10 minutes. DO NOT SQUEEZE OR
WRING OUT THE NATURAL COOL MOISTURE™ FILTER. Always place filter back in
the humidifier wet.

• To prevent mineral deposits use DuraFree™ Humidifier Water Softener, part no.
AC817, each time the Water Tank is refilled.

• Always purchase Honeywell or Duracraft Brand Natural Cool Moisture™ filters as the
fan motor of this humidifier and the Natural Cool Moisture™ filter are designed to
function efficiently as a set. Using any other filter could damage the motor or reduce
the humidifier’s performance.

• Be sure to empty water from the Water Tank and Base when not in use.

END-OF-THE-SEASON AND STORAGE

• Follow weekly CLEANING instructions when the humidifier will not be used for at least
one week or more, or at the end of the season.

• At the end of the season, remove and throw away the filter; do not store with a used
filter.

• Dry the humidifier completely before storing. DO NOT store with water inside the Base
or Water Tank.

• Pack the unit in its original carton and store in a cool, dry location.

• Before next use, remember to install a new filter and clean the humidifier.

TROUBLE SHOOTING

Q: I hear the fan turning, but I don’t see any mist. Is my humidifier operating pr o p e r l y ?
A : Dry air is pulled through the Natural Cool Moisture™ system and a fan disperses

invisible, moisture balanced air. There is no “mist” emitted. When operating normally

you will feel only cool air coming from the unit. Monitor the water level in your Tank/

Base. If you notice a decrease in the Water Tank over 24 hours then the unit is

operating normally.

Q: My unit has been running for several hours. I hear the fan spinning, but I do not

notice the water level in the tank decreasing.

A: First, check the Natural Cool Moisture™ filter to be sure it is wet. If the pad appears

dry, remove it from the Base and gently rinse under cool water. Reposition wet filter
in the Base. You may also want to note the current moisture level in your home. If the
humidity level is over 60% the unit will not put out much moisture as your air is
already saturated.

Q: The humidifier is not running (the fan is not even spinning), but all (or some) of the

lights are on.

A: If the Desired Humidity light is ON: The Moisture Control knob may be set too low.

Moving the Moisture Control knob to the highest black dot before the “+” sign should
restart the unit.

Q: The Moisture Control knob was set according to the manual, but the humidifier

never seems to turn back on. Is something wrong?

A: The Moisture Control knob may be set too low. Moving the Moisture Control knob to

the highest black dot before the “+” sign should restart the unit. Reset the Moisture
Control knob following the instructions under FEATURES.

Q: The Moisture Control knob was set according to the manual, but the humidifier

never seems to turn off. Is something wrong?

A: The Moisture Control knob may be set too high. Reset the Moisture Control knob

following the instructions under FEATURES.

Q: My filter has turned light brown and rust colored. Do I need a new filter?
A: Probably not. Since your filter has been made with HealthShield™ technology the

change in colour indicates only a mineral deposit. Soak filter in a sink full of cool
water to help break up deposits. The discoloration may remain but will not affect the
humidifier’s performance.
