Step 3
Bi-Weekly Maintenance
Removing Scale
1. Fill the humidifier base with one 8 oz.
cup of undiluted white vinegar. Let
solution stay 20 minutes.
2. Clean all interior surfaces with a soft
brush. Dampen a soft cloth with undi-
luted white vinegar and wipe out the
base to remove scale.
3. Rinse thoroughly with clean warm
water to remove scale and cleaning
solution.
Disinfecting Base
1. Pour 1 gallon of water and 1 teaspoon
chlorine bleach into the base. Let
solution stay for 20 minutes, carefully
swishing every few minutes. Wet all
surfaces normally exposed to water.
2. Empty base after 20 minutes. Rinse
with water until bleach smell is gone.
Allow unit to dry out completely.
NOTE:
The water bottle should be
cleaned in the same manner as the base.
Rinse thoroughly with clean water after all
steps are complete.

Replacing Parts
1. Install a new filter (MAF-1) or the filter
previously set aside if it is in good
condition into the base. Coil the filter
and position it between the uprights in
the bottom of the base. The start and
finish of the coil should be captured in
the center of the base (see diagram)
and the filter should be resting on the
floor of the base.
2. Return the housing assembly to the
top of the base. Return the water bot-
tle to the right of the housing assem-
bly and reposition the humidifier to its
operating position.
3. The humidifier is now ready to be
filled for operation.

instructions at end of humidification
season.
2. Remove filter and dispose of properly.
3. Let humidifier dry completely before
storing. Do not store with water inside
base or bottle.
4. Store in cool, dry location.
5. Install a new filter in clean humidifier
before next season begins.
Note:
“Bi-Weekly Maintenance” is
also recommended if you do not plan
to run the humidifier for one week or
more.
