Assembly and Operation
1) Unpack humidifier from carton.
2) Remove all packaging materials. Check to see that you have all of the fol-
lowing items before discarding packaging:
Fill hose Cord Set
Evaporative wick Two end covers
Two water bottles with caps Caster kit
Air Care filter if unit is an Air Care model
NOTICE: The wick and Air Care filter are packaged to prevent breakage
in shipping. They must be removed from the unit and correctly installed
according to these instructions prior to operation to prevent damage to
the unit.

CASTERS

3) Remove the water bottles, chassis and evaporative wick from the base of
the humidifier. Turn the base of the empty humidifier upside down. Insert
the caster stem into the large caster holes in the four corners of the humidifi-
er bottom. The casters should fit snugly and be inserted as far as possible.
Do not force. When all four casters are in place, turn the unit right side up.

EVAPORATIVE WICK

4) The wick has a mounting rib on
the top edge which hooks over a rib
at the inside back of the cabinet. This
allows the wick to hang in the water
channel (see illustration). Hang evapo-
rative wick into cabinet as shown.
AIR CLEANING FILTER (Models
4D7 800, 497 800, 497 300,
447 401, 447 301 & 427 300)
5) The Air Care filter has four tangs that
engage into four keyhole slots that
mount the Air Care filter onto the out-
side of the back of the cabinet.

CHASSIS/POWER PAK

6) Place the chassis/power pak unit into the cabinet ensuring that
chassis/power pak seats correctly onto the front and back edges of the
cabinet.

BOTTLES

7) Fill the bottles with cool, fresh, preferably unsoftened water. If you
have only softened water available in your home, you may use it, but you
will notice a buildup of minerals on the wick much sooner. The bottles hold
2.75 gallons each. When filling the bottles, be careful not to pressurize
them by over filling. Bottle damage can result from this. To reduce carrying
weight, the bottle may be partially filled and unit will still operate properly.
A fill hose is provided with your humidifier which will fit most faucets.
