4 5
times, but this is normal), the bulb must be replaced with the same special 3.5W
bulb. See the enclosed order form. The UV germicidal bulb will operate at maximum output for approximately 2,000 hours. The UV germicidal bulb may operate
longer than 2,000 hours but at a reduced output. To keep your humidifier operating at maximum efficiency it is recommended that the UV germicidal bulb be
replaced after 2,000 hours of use.
REFILL INDICATOR - When illuminated, the water tanks need refilling.See the
section “Filling the Water Tank”. If still illuminated a few minutes after full tank is
placed on base, reposition water tanks. (Unit will operate with only one water tank.)
Each time you fill tanks, rinse tanks, hot water reservoir and cold water reservoirs.
Clean them according to CLEANING INSTRUCTIONS if minerals or film are present.
RELATIVE HUMIDITY CONTROL - This controls the humidity level. If moder-
ate humidity is desired, the control should be turned counterclockwise toward “LO”;
and if higher humidity is desired, clockwise toward “HI”.
NOTE: When you unpack your humidifier, you may find it has droplets of water on
some surfaces. This is normal as every unit is tested prior to shipping.
Carefully unpack humidifier and remove all packing material.
OPERATING INSTRUCTIONS
1. Place the base of the unit on a firm, flat, level and water resistant surface.
2. Fill the water tanks according to the instructions below and place on humidifier
base.
3. Plug the power cord firmly and completely into the wall outlet.
4. Turn the power switch to either the LO or HI position (Lights may flicker momentarily). Then turn the relative humidity knob clockwise until you hear a faint click
and the power light comes on. It will be normal for the humidifier to take a few
minutes to warm up and begin to mist.
5. When the water tanks are empty, (after approximately 36 hours running time), the
“REFILL WHEN LIT” lamp will go on, and the unit will stop heating. Refer to the
“FILLING THE WATER TANKS” section.
6. Whenever the water falls below the level of the probes during operation, the
heating element will shut off and stop heating, and the REFILL indicator will light.
7. The unit will operate as long as there is water in either tank and unit will operate
with either one or both tanks.
FILLING THE WATER TANKS
1. Before filling the water tanks, turn the POWER switch to the “OFF” position and
unplug unit. Refer to CLEANING INSTRUCTIONS.
2. Remove water tanks from base, turn each tank upside down and remove tank
cap by turning counterclockwise. Fill tank with clean cold tap water.
If using distilled water, add a few grains of table salt to each tank.
Replace the tank cap by turning clockwise. Tighten firmly.
3. Carefully pick up tank, since it will be heavy when full, and slippery if wet.
4. Place water tanks on base. Make sure tanks are properly placed, otherwise, the
humidifier will not work correctly.
USING THE MEDICATION CUP
In order to add a medicated vapor to the “mist” output:
1. Turn the POWER switch to the “OFF” position and allow the steam diffuser
to cool.
2. Carefully add liquid medication to medicine cup. DO NOT fill the cup more than
half full.
HOW YOUR
SLANT/FIN
WARM MIST
HUMIDIFIER WORKS
The model GF-300 and GF-350
humidifier uses a two-step
approach to eliminate potentially harmful microorganisms from
the water before they are
spread with the mist into the air.
The first step uses a UV germicidal bulb, located inside the
base of the humidifier, that
shines on the water through a
special glass tube as it passes
from the cold water reservoirs
to the hot water reservoir. The
second step is the boiling
action that takes place in the hot water reservoir just before the mist is distributed to the air in the room. These two methods limit the likelihood of harmful
microorganisms getting into the atmosphere and being breathed by you, your
family and pets.
CONTROL PANEL
POWER SWITCH —
LO AND HI POSITIONS
When the switch is turned
to the “LO” or “HI” setting
and the unit is plugged in,
the power is on. With the
unit running in the LO setting, it will be producing
vapor at a lower rate than
when running in the HI
setting.
OFF POSITION - This cuts power to unit and should be used (in addition to
unplugging unit) before moving, performing maintenance, etc.
REPLACE UV BULB
If the “REPLACE UV BULB” signal light is continuously illuminated during normal
use (an occasional faint glow may occur when switching power on or other
WEEKLY CLEANING AND MAINTENANCE ADVISORY
At least weekly cleaning is recommended, when the unit has been in use. Regular
cleaning prevents mineral scale buildup in the hot water reservoir. It also helps prevent
buildup of bacteria, molds or other microorganisms in the tank or system. This ensures
that your humidifier will operate at maximum efficiency. (See page 6 for full cleaning
instructions.)

3. Carefully place medicine cup on top of steam diffuser
4. Turn the POWER switch to either the LO or HI position.
5. After use, remove the cup from the unit and clean any residue from the cup
with warm water.
WARNING:
DO NOT use any liquid medication other than those specifically recommended
for use with a steam vaporizer or warm mist humidifier.
DO NOT pour medication directly into the steam diffuser openings nor add it to
the water in the tank or tray.
MINERAL ABSORPTION PAD INSTRUCTIONS
Warm mist humidifiers do not spread fine mineral dust into the air that you
breathe nor on your furniture, the way that other type humidifiers do. The mineral dust remains trapped in the humidifier hot water reservoir. Use of mineral
absorption pads will play a major role in capturing and removing minerals from
hot water reservoir, and preventing a stubborn mineral buildup. The unit can run
without pads, but more frequent cleaning will be required.
1. Before starting humidifier, place mineral absorption pad in the hot water
reservoir. After the humidifier has been operating, the water will become
HOT, and CAUTION should be exercised when handling mineral absorption
pad. It is best to allow humidifier water to cool down, and to use tongs or
long tweezers when handling pad.
2. The useful life of the mineral absorption pad will vary, depending on the min-
eral content of the water used. In areas of moderate mineral content water
supply, the mineral absorption pad should be changed after approximately
(3) weeks of continuous use. If the water is “Hard Water”, the pad should be
changed more frequently. The best way to tell when the pad should be
changed is to examine it AFTER the water has cooled down, to see if it is
still soft and pliable. When the pad is near the end of its life, it becomes stiff
and hard and should be replaced with a new pad. Another sign to change
pad is when scale begins to buildup on interior of hot water reservoir. If pad
appears to disintegrate (normally due to use of softened water) discontinue
use of pads.
CLEANING AND MAINTENANCE
Water contains minerals and other particles. During operation most of these minerals
will remain in the water reservoir. Gradual buildup of deposits will coat the hot water
reservoir and reduce its efficiency. The importance of routine cleaning and care cannot be over-emphasized. Hard water contains more minerals and other particles.
CLEANING INSTRUCTIONS
Failure to perform the necessary cleaning steps will damage unit.
1. Before cleaning, set CONTROLS to “OFF” position and unplug unit.
2. Remove water tanks from humidifier base, and drain water from tanks.
3. Allow at least 15 minutes for the hot water to cool after shutting unit “OFF”
before moving base.
Rotate steam diffuser counterclockwise until steam diffuser slots line up with
tabs in base, and lift up. Rotate steam dome until steam dome slots line up with
tabs in base and lift out. Remove mineral absorption pad from hot water reservoir using tweezers or tongs to prevent burns from hot water. When the cleaning procedure is completed, replace mineral absorption pad. To drain water
from humidifier base, grasp with both hands and tilt to the side, draining water
into the sink. BE CAREFUL NOT TO HAVE DRAINING WATER FALL INTO
CONTROLS OR VENT OPENINGS. DO NOT drain in any manner other than
indicated.
WARNING: DO NOT place directly under running faucet. Turn the
base upside down and remove the drain tube cap by turning it counterclockwise.
Clean out any foreign matter that has accumulated inside the fitting from which
the cap was removed. After cleaning, replace this cap tightly by hand. Pour a
small amount of water into the hot water reservoir and check for leaks from this
cap under the base.
4. Pour about 1 cup of white vinegar into either reservoir and allow it to soak
for only 20 to 30 minutes.
5. Hold the base of the humidifier over the sink and tilt it on its side to empty
the vinegar. Fill the cold and hot water reservoirs with clean, warm water to
remove all traces of the vinegar. Remove any buildup of minerals in the hot
water reservoir and from the two metal water level probes (they appear like
two metal wires) using a small brush, such as a toothbrush. NOTE: The
buildup is due to water hardness. The harder your water, the more often this
maintenance will be needed. Empty all of this water by turning the unit on
its side. If minerals remain in the metal (stainless steel) boiler cup, a metal
scraper can be used to scrape off the mineral deposits. Be careful not to use
any metal blade on any plastic parts.
DO NOT ALLOW WATER TO ENTER THE BOTTOM OF THE HUMIDIFIER
BASE OR ANY OTHER OPENINGS, OR IMMERSE THE CORD AND PLUG.
6. Disinfect the water tanks using a solution of one teaspoon of household
chlorine bleach in 1 gallon of water. Let the solution sit for 20 minutes,
swishing every few minutes to wet all surfaces. Empty the tanks completely;
rinse thoroughly until all of the bleach smell is gone. Fill the tanks with
fresh, cool water and replace them onto the humidifier base.
7. NEVER use any metal or hard objects to clean plastic parts which may
cause scratching of the plastic parts. The only exception to this is the metal
part of the hot water reservoir. A metal scraper can be used to clean this
part only. NEVER use gasoline, kerosene, glass cleaner, furniture polish,
paint thinner or other household solvents to clean any part of the humidifier.
8. Each day the reservoirs and tanks should be drained, rinsed and refilled
with fresh tap water.
9. To clean exterior surfaces, use a solution of water and mild detergent with a
wrung-out damp cloth. Rinse and wring out the cloth and wipe the exterior
surfaces again. Finally, wipe with a dry cloth. Allow sufficient time to dry
before plugging the electrical cord into the outlet.

10. After base is totally cleaned and dried, replace mineral absorption pad. Place
steam dome on base by aligning its slots with tabs in base. (You may have to
reposition steam dome to other set of tabs, because it will only fit one way.)
Rotate steam dome clockwise until it locks. Place steam diffuser on base so
that the slots in steam diffuser line up with tabs on the base. Rotate steam
diffuser clockwise until it locks in place.
11. Replace tanks. Plug in the unit and resume normal use.
CHANGING THE UV GERMICIDAL BULB
1. If the “REPLACE UV BULB” indicator illuminates during normal use, it is time
to change the UV germicidal bulb, which is a special 3.5W bulb.
2. Turn the POWER switch to the “OFF” position, unplug it and allow it to cool.
3. Remove the water tanks from the
base of the humidifier. Remove steam
diffuser and steam dome by rotating
them counterclockwise and lift up.
4. Place the base of the humidifier over
the sink and tilt the unit to remove any
remaining water.
5. Carefully turn the base of the humidifier over and place it upside
down on a flat level surface. You will
see a door at front of unit that is
closed with two Phillips head screws.
6. Using a Phillips head screwdriver, carefully turn the screws counterclockwise
until the screws separate from the door.
7. Open the door, by pulling forward. The UV germicidal light bulb will be visible.
Pull the door out the minimum amount to have access to unscrew bulb from
socket.
8. Take a replacement 3.5W UV germicidal bulb that you purchased from
Slant/Fin Corporation or another supplier and change the bulb. To prolong
the life of the bulb, limit your direct contact with the glass of the bulb by using
a cloth or tissue to screw it into place.
9. When the new bulb is in place, close the door and replace the screws by
using your Phillips head screwdriver and rotating them clockwise until they
are just tight.
DO NOT OVER TIGHTEN.
10. DO NOT turn power on, while UV lamp door is open, and DO NOT view illuminated bulb directly because eye damage may occur.
11. Turn the unit upright, place the water tanks on top of the base of the humidifier, plug the unit in, and turn the POWER switch to either the LO or HI position. The “REPLACE UV BULB” indicator should no longer be lit.
IMPORTANT NOTE: Even though you will not receive maximum germicidal effects,
you can still use your GF-300 and GF-350 humidifier until the replacement bulb
arrives.
