both hands. Set aside.
4. Carefully pull the plastic feed tube (2) out of the distribution tray (5) at the top of the evaporative
assembly (4). Pull this assembly out by grasping at top and tipping out.
5. Unsnap the distribution tray (5) from the scale control insert (8). Lightly scrape out or brush off

the tray in vinegar or a lime-removing agent is helpful when trying to remove stubborn mineral
deposits.
6. Slide the Humidifier Pad (7) out from the scale control insert (8). Clean the scale control insert
of mineral deposits. Replace the Humidifier Pad (Part No. S1-HUPAD10 for Model 5000

Slide the Humidifier Pad back into the scale control insert with the colored spot up and snap the
distribution tray (5) back into place.

Replace tube if it is cracked, brittle, or has been damaged.
8. Reinstall the evaporative assembly (4) into the humidifier by fitting its drain into the round
receptacle at the base of the humidifier. Push the assembly in at the top until it snaps into place.
Push the end of the feed tube back firmly into the distribution tray and replace the front cover.
9. Remove the drain line (9) from the bottom of the humidifier. If applicable, flex it to loosen any
mineral deposits or blockage. Then flush it with water under pressure. If it does not properly
clear, replace it. Slip drain line back onto the drain fitting. Make sure the drain line has a
constant downward slope and is not flattened or blocked.
