MEDICINE

 

CUP

:

Medicated vapor can be distributed into the air by 
using the Medicine Cup at the top of the unit.  To 
add medicine to the medicine cup:

1. Turn the humidifier OFF and wait 10 minutes 

for the unit to cool.

2. Remove the Medicine Cup from the Power 

Unit by pulling firmly upward.

3. Fill the cup halfway with liquid medicine.
4. Carefully reinstall the Medicine Cup back 

into the Power Unit.

5. After use, remove and clean the Medicine 

Cup with warm water.  Reinstall the clean 
and dry Medicine Cup in the Power Unit.

Warning:  DO NOT use any liquid medicines 
other than those specifically recommended 
for use with steam vaporizers or warm humid-
ifiers.  DO NOT pour medicine through the 
grille or add it to the water tank.

Honeywell assumes no responsibility for con-
sequences resulting from the use of medicine 
in this humidifier.

WEEKLY

 

CLEANING

:

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

Cleaning is a two step process:  scale removal 
and disinfecting.  Be sure to perform these in 
the proper order to avoid harmful chemical 
interactions.
• Turn off and unplug the humidifier.  Wait at 

least 10 minutes for the unit to cool.

• Remove the Tank.
• Pull the latch located under the water tank and 

lift off the Power Unit.  Check the condition of 
the heating element.  Follow the CLEANING 
THE HEATING ELEMENT instructions if min-
eral build-up is heavy.

• Empty any water from the Base and Water 

Tray.

• SCALE REMOVAL - WATER TRAY:

1.  Fill the Water Tray with either 1 cup (8 oz.) 

of undiluted white vinegar OR DuraRinse

TM

 

Humidifier Cleaner (AC-816) following the 
bottle instructions.

2.  Let the solution stand for 20 minutes.

3.  With the solution in the Water Tray, remove 

scale from all interior surfaces with a soft 
cloth or brush.

4.  Rinse the Water Tray thoroughly with water 

to remove the scale and cleaning solution.

DISINFECTING - TANK & WATER TRAY:
1. Fill the Water Tank with 1 teaspoon of 

household bleach and 1 gallon of water.  
Pour some solution into the Water Tray.

2. Let the solution stand for 20 minutes.
3. Rinse with water until the smell of bleach is 

gone.

NOTE:  THE USE OF OTHER WATER TREAT-
MENT PRODUCTS, CHEMICALS, SOAPS, 
DETERGENTS OR ABRASIVE CLEANSERS 
NOT RECOMMENDED ON OUR WEBSITE OR 
REFERENCED IN THIS MANUAL MAY CAUSE 
DAMAGE TO THE HUMIDIFIER OR AFFECT 
PERFORMANCE.  SEE ACCESSORIES.

CLEANING

 

THE

 

HEATING

 

ELEMENT

:

The frequency of performing this special mainte-
nance depends upon the hardness of your water.  
To remove minerals built-up on the heating ele-
ment:

Turn off and unplug the humidifier.  Allow at 
least 10 minutes for the unit to cool.

The heating element is located on the bottom 
of the Power Unit.

Use a non-metallic brush or soft, dry cloth to 
wipe the outer surfaces of the heating element.  
Some deposits may remain, but they should 
not interfere with operation.

DO NOT clean the heating element under running 
water since it may cause damage or personal 
injury.

CARE

 

AND

 

STORAGE

:

Follow WEEKLY CLEANING instruction when 
the humidifier will not be used for at least one 
week or more.

Remove all water from the Water Tray, Base 
and Tank before storing.

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

Clean the humidifier after prolonged storage.
