Your Humidifier is engineered to give helpful and trouble-free humidification. For maximum efficiency the following cleaning procedures should be carried
out at the end of each heating season:
1. Turn off water supply and electrical power to humidifier.
2. Remove water distributor tube, distributor trough, evaporator pad and drain pan. The evaporator pad may be AT
removed from either the top or bottom of the humidifier. Clean excessive mineral deposits from the distributor trough, OUTSIDE RECOMMENDED
cover, drain pan and humidifier cabinet. A solution of 1/2 vinegar & 1/2 water will help loosen mineral deposits. TEMPERATURE SETTING
3. If the evaporator pad has excessive mineral deposits, replace with a new "990-13" evaporator pad. Install trough
and drain pan. Replace cover and the distributor tube to proper position over the distributor trough. -20"YF -29_C 15%
4. In heavy mineral areas or if the solenoid valve fails to function disconnect the 1/4" water supply line from the
-10"YF -23"/O 20%
solenoid valve. Remove the brass strainer body (P.N. 990-18) from the solenoid valve. Carefully pull the strainer
screen (P.N. 990-17) from the orifice fitting (P.N. 990-16). Clean the mineral deposits from all parts. If the orifice is 0"YF -18_C 25%
clogged, it may be opened by inserting a small needle. Reinsert the filter into the orifice fitting and screw the brass +10"YF -29_C 30%
strainer body into the solenoid valve.
5. Reconnect the 1/4" water line to the solenoid valve if necessary. Turn on the water supply and check all points for +20"YF - 7"YC 35%
leakage. The operation of the unit may be checked by starting the furnace. The humidifier operates only when the +30"YF - 1_C 40%
furnace blower is running or the burner circuit is energized. The humidifier is now ready for operation.
6. During the summer, turn off water supply and electrical power to humidifier. Close air damper.

The operating principle of the humidifier is based on the most efficient
and economical means of evaporating water to the air. The humidifier
uses only six watts of electrical power during operation, less than the
smallest household light bulb. The heat necessary for evaporating
water is produced by the furnace.
The water supply to the humidifier is controlled by the electric solenoid
valve. The humidistat connected in series with the solenoid provides
low voltage control of the humidifier. The humidistat is designed for
wall mounting in the living area or surface mounting on the return air
duct. ELECTRICAL RATING: 24 VAC / 60 Hz. DO NOT SET
RELATIVE HUMIDITY TOO HIGH DURING COLD WEATHER.
EXCESSIVE HUMIDITY MAY CAUSE CONDENSATION ON
WINDOWS OR IN WALLS. REFER TO RECOMMENDED SETTINGS
AS DESCRIBED IN THE HUMIDtSTAT OWNERS MANUAL.
Water flows through a strainer, is metered through an orifice to provide
the proper amount of water, and is supplied to the evaporator pad by
the distributor trough. Approximately 200 CFM of air is by-passed from
the warm air plenum through the humidifier and returned to the cold air
plenum. Moisture is evaporated to the air passing through the
evaporator pad.
Minerals are not blown into the air stream as occurs in atomizing
humidifiers; they are left on the evaporator pad where a high
percentage is carried off with the waste water.
When the humidifier is installed and operating, no adjustments are
necessary other than setting the control knob on the humidistat to the
desired level of humidification. Leave knob on the humidifier in "HI" or
"WINTER" position.
To turn the humidifier off, close water supply valve, switch electrical
power off and turn humidistat off. If furnace is used for summer cooling
or ventilating set air damper on "LOW" or "SUMMER".
