8 9Plumbing and Setting the Water LevelNOTE: Use copper tubing only to plumb the humidifier.Select the nearest cold water pipe and install the saddle connector andneedle valve (provided) by following the instructions supplied with thevalve.WARNING: Do not use any line connected to an air conditioner.Lightly clean the tubing ends with fine sandpaper before making con-nections.1.2.Uncoil the copper tubing andconnect one end to the saddlevalve. Use the compressionfittings found in the self-piercing saddle valve partsbag.Place the brass compres-sion nut over the tubing,then slide the brass ferruleover the tubing.Fully insert the tubing intothe saddle valve fittingand tighten the compres-sion nut. (Do not over-tighten; moderate tightness should preventleakage.)Thoroughly flush the supply tubing after attaching it to the saddlevalve. This will clear the line of debris which could block water flowat the float valve.Route the tubing to the humidifier float valve, keeping the tubing awayfrom sharp edges.Connect the remaining end of the tubing to the humidifier float valve.Open the saddle valve so that the water flows slowly and gently into thewater pan.Prior to mounting, adjust the humidifier’s water level by following theseinstructions:Set the humidifier reservoir on a level surface.Allow the unit to fill until the float valve shuts off the incoming flow ofwater. (The water should be 2-3/8" deep, plus or minus 1/8". If it isnot, further adjustment will be necessary.).•••4.5.6.7.••Figure 7—Saddle Valve and FittingsIf the water level is too high, remove enough water from the reservoir toallow the float valve to automatically fill and shut off the water. This willverify that your final adjustment is correct.Shut off the water supply and remove all water from the reservoir.Mount the humidifier according to Options A, B or C, shown on pages5-7.Check the two compression fittings—one at the saddle valve, the other atthe float valve. Stop any leakage by tightening the fittings.Connect the humidifier’s overflow provision to a suitable waste drain.A standard garden hose or a 3/8" N.P.T. male fitting (not supplied)can be attached to the overflow fitting.Provide support at many points along the hose to prevent kinks—particularly near any heat source.Turn the water to the humidifier on. The float valve should shut the wateroff when the pan is filled to 2-3/8".Make sure the humidifier is plugged into a powered outlet.Adjust the compensating humidistat according to instructions providedwith the unit.8.9.10.11.12.••1.14.15.CAUTION: To prevent valve seat damage, never adjust the humidi-fier’s water level without supporting the float arm. Make adjustmentsin small increments.To raise the water level, push down in the center of the float arm.(See Figure 8-A, below.)To lower the water level, hold the float on the bottom of the reservoirwith one hand and pull up on the center of the float arm with the otherhand. (See Figure 8-B, below.)••Figure 8-A—Raising thewater levelFigure 8-B—Lowering thewater level |
