Plumbing and Setting the Water Level

NOTE

: Use copper tubing only to plumb this humidifier.

1. Select the nearest cold water pipe and install the saddle connector and

needle valve (provided) by following the instructions supplied with the

valve.

WARNING

: Do not use any line connected to an air conditioner.

2. Lightly clean the tubing ends with fine sandpaper before making connections.

3. Uncoil the copper tubing and

connect one end to the saddle

valve. Use the compression fit-

tings found in the self-piercing

saddle valve parts bag.

• Place the brass compression

nut over the tubing, then slide

the brass ferrule over the

tubing.

• Fully insert the tubing into

the saddle valve fitting and

tighten the compression nut.

(Do not over-tighten; moderate tightness should prevent leaking.)

• Thoroughly flush the supply tubing after attaching it to the saddle

valve. This will clear the line of debris which could block water flow at

the float valve.

4. Route the tubing to the humidifier float valve, keeping the tubing away

from sharp edges.

5. Connect the remaining end of the tubing to the humidifier float valve.

6. Open the saddle valve so that the water flows slowly and gently into the

water pan.

7. Prior to mounting, adjust the humidifier’s water level by following these

instructions:

• Set the humidifier reservoir on a level surface.

• Allow the unit to fill until the float valve shuts off the incoming flow of

water. (The water should be 2-3/8" deep, plus or minus 1/8". If it is not,

further adjustment will be necessary.)
