Slant/Fin Comprehensive Guide to Slant Fin Humidifier Maintenance, UV Bulb Replacement, and Mineral Absorption Pads

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 humidi- fier 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 illu- minated bulb directly because eye damage may occur.

11.Turn the unit upright, place the water tanks on top of the base of the humidifi- er, plug the unit in, and turn the POWER switch to either the LO or HI posi- tion. 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.
