Model 1000 Humidifier Installation Manual
Maintenance
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 the water supply and electrical power to the humidifier.
2. Remove cover, water distributor trough, used Vapor Pad
deposits from the distributor trough, drain pan, pad rails and humidifier cabinet. A solution of 1/2 vinegar & 1/2
water will help loosen mineral deposits. Inspect drain hose, clean or replace as necessary.
3. Insert a new GA19 Vapor Pad
cover, reconnect electrical plug. Replace Vapor Pad
4. In heavy mineral areas or if the solenoid valve fails to function disconnect the 1/4" water supply line from the
solenoid valve. Carefully pull the strainer screen (GFI #7564) from the valve body. Clean the mineral deposits from
all parts. If the orifice is clogged, it may be opened by inserting a small pin. Reinsert the filter into the valve body.
5. Reconnect the 1/4" water line to the solenoid valve if necessary. Turn on the water supply and check all points for
leakage. The operation of the unit may be checked by starting the furnace. The humidifier operates only when the
furnace blower is running or the burner circuit is energized. The humidifier is now ready for operation.
6. During the summer, turn OFF the water supply and electrical power to the humidifier.
