STORAGE TIPS

If you do not plan to use your humidifier for an extended period of time, such
as during the summer months, it is important that you follow these instructions
to help prevent problems from developing in the unit.
1. Clean your humidifier as instructed in the section titled, “Cleaning and
Maintenance”.
2. Make sure all water is emptied from the tank and the hot and cold water
reservoirs.
3. Dry your unit thoroughly.
4. Leave the tank cap off to expose the tank to air.
5. Pack your humidifier in its original carton and store it in a cool, dry place.

SERVICE

DO NOT attempt to repair this humidifier yourself. For repairs covered under
the warranty, contact Slant/Fin by telephone or mail for a Return Authorization
Number. Have other repairs professionally performed.

GLOW

It is normal to see the humidifier glow when operating in a darkened room.
This glow results from the internal illumination of the 3.5 watt UV bulb.
However, no ultraviolet light, even at this harmless level, passes through the
UV-proof cabinet into the room.

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 ON-OFF switch to the “OFF”
position, unplug it and allow it to cool.
3. Remove the water tank from the base
of the humidifier.
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 that is closed with a screw.
6. Using a Phillips head screwdriver, carefully turn the screw counterclockwise
until the screw separates from the door.
7. Open the door. The UV germicidal light bulb will be visible.
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 screw by using
your Phillips head screwdriver and rotating it clockwise until it is just tight. DO
NOT OVER TIGHTEN.
10. Turn the unit upright, place the water tank on top of the base of the humidifi-
er, plug the unit in, and turn the ON-OFF switch to the “ON” position. The
“REPLA CE 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-200 and GF-210 humidifier until the replace-
ment bulb arrives.
