furnace blower is runningand the humidistatcalls for additional
humidity. T wo methodsare shown(Fig. 17 and Fig. 18):

FURNACE WITH SINGLE SPEED 120 VAC BLOWER ONLY.
CAUTION: Do not use this methodwith multi-speedblow-

AIR FURNACE INCLUDING FURNACE WITH OTHER THAN 120
VAC BLOWER MOTOR OR FURNACE WITH MULTI-SPEED

NOTE: Some furnacesare equippedwith accessorytermi-

IF SWEATING OF WINDOWS OR WALLS OCCURS OR IF AIR
IS TOO DRY:
Check dial seffing. Indicatorshould point to the lowest24 hour
temperature. If settingdoes not agree, readjust knobto proper
i numberand wait 24 hoursfor sweatingto stop. Ifdial settingwas
correctand conditions have not changed, rotate knob beck and
forthfromTEST to MINIMUM HUMIDITY SETTING. If humidifier
goes ON and OFF, control is operatingproperly.

AIR CONDmONING - IMPORTANT:
If your furnace has air conditioning (cooling),dose the damper
completely duringsummer months and tum the humidistat t o the
MinimumHumiditysetting.BE SURE TO OPEN DAMPER DUR-
ING HEATING SEASON AND RESETTHE HUMIDISTAT.
WATER FLOW RATE:
At standardwater line preseureof 50-60 PSI (poundsper square
inch), water willflow through humidifierat approximately four (4)
gallonsper hour.About 0.7 gallonspar hour of the four will be
evaporated,leaving3.3 gallons to be drainedaway.Since the fur-
nsoe only runsan estimated30-40% of the beating season, and
the_umldifter is wired to operate only with the fumase blower,
and only when humidityIs required,the actual amount of water
drainedper day is much less than wouldbe expected.
