Maintenance
Maintenance instructions for models mounted on the face of a vertical return duct, side of a horizontal return duct, or mounted behind a wall using discharge extension
Your humidifier is constructed from quality materials to assure superior performance during normal operation. The motor bearings are permanently lubricated and do not require oiling. The motor is also thermal overload protected against extreme conditions.
To clean the unit:
1.Turn the power to the furnace OFF or turn off the electric switch to the humidifier, if provided.
2.Disconnect the humidifier motor leads.
3.Turn off the humidifier water supply from the saddle valve and remove water line from humidifier.
4.Remove the humidifier from the wire mounting bracket.
5.Remove the discharge dome from the humidifier by pressing on the sides of the dome and lifting upward.
6.Lift the entire atomizing assembly from the water reservoir pan.
7.Remove the pump from the end of the impeller shaft. If the pump is stuck in the motor drive shaft, run hot water over the end of the shaft for a few seconds to loosen the pump.
8.Flush water through the impeller tube, ensuring that the six holes at the top of the impeller tube are open and clear of mineral deposits. A pipe cleaner works well for this cleaning operation.
Note: The impeller tube and pump can become clogged by algae formations prevalent in certain water sources. The addition of 10 drops of bleach to the water reservoir pan each week is advisable.
9.Replace the pump into the impeller shaft.
10.Carefully rotate the impeller to ensure it turns freely. Do not force the impeller shaft to turn or breakage could result.
11.With the atomizing assembly removed, clean the water reservoir pan thoroughly. We suggest either a water/white vinegar solution or liquid humidifier cleaner.
12.Reassemble and remount the humidifier by reversing steps 6, 5, and 4.
13.Reconnect the water line and motor leads to the humidifier, turn on the water supply from the saddle valve and restore electrical power.
