Maintenance
Your humidier is engineered to give helpful and trouble-free humidication. For maximum efciency 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 humidier.
2. Remove cover, water distributor trough, used Vapor Pad
®
, pad rails and drain pan. Clean excessive mineral
deposits from the distributor trough, drain pan, pad rails and humidier 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
®
(GFI# 7919; black notch on top). Install trough, pad rails and drain pan. Replace
cover, reconnect electrical plug. Replace Vapor Pad
®
yearly for peak performance.
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 orice is clogged, it may be opened by inserting a small pin. Reinsert the lter 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 humidier operates only when the
furnace blower is running or the burner circuit is energized. The humidier is now ready for operation.
6. During the summer, turn OFF the water supply and electrical power to the humidier.
