form. The UV germicidal bulb will operate at maximum output for approximately
2,000 hours (typically 1 to 2 years of normal operation). 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 ger-
micidal bulb be replaced after 2,000 hours of use.
REFILL/CLEAN INDICATOR - When illuminated, the water tanks need refill-
ing. 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 mod-
erate 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. Fill the water tanks according to the instructions below and place on
humidifier base.
2. Plug the power cord firmly and completely into the wall outlet.
3. Turn the switch to either the LO or HI position. It will be normal for the
humidifier to take a few minutes to warm up and begin to mist.
4. When the water tanks are empty, (after approximately 36 hours running
time), the “REFILL/CLEAN WHEN LIT” lamp will go on, and the unit will stop
heating. Refer to the “FILLING THE WATER TANKS” section.
5. Whenever the water falls below the level of the probes during operation, the
heating element will shut off and stop heating, and the REFILL/CLEAN indi-
cator will light.
6. 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.
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 potential-
ly harmful microorganisms from
the water before they are
spread with the mist into the air.
The first step uses a UV germi-
cidal 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 distrib-
uted 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 set-
ting, 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 illuminated during normal use, the
bulb must be replaced with the same special 3.5W bulb. See the enclosed order
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.)
