Maintenance
Periodic cleaning is required for the efficient and safe operation of this humidifier. Inspect the humidifier approximately once a month for mineral and algae growth. Algae may develop inside the humidifier if certain conditions exist in the water supplying the unit. Algae is a slimy substance which can be green, brown or white. It is advisable to add an algaecide to the water on a weekly basis. This algaecide can be 10 drops of bleach or bacteriostatic liquid/powder. Periodic cleaning and removal of accumulated mineral deposits and algae growth is the only required maintenance of this unit. The frequency of this maintenance will depend on the mineral content, or hardness, of the water being supplied to the humidifier.
To inspect the unit:
1.Turn the electrical power to the furnace OFF.
2.Set the humidistat to the OFF position and disconnect the humidifier from the power source.
3.Turn off the water at the saddle valve by turning clockwise.
4.Remove the window panel (panel with label attached) on the front of the humidifier by sliding it up, pulling the bottom away from the unit and then pulling down.
To clean the unit:
1.If the evaporator pad appears clogged with mineral deposits, remove the drain plug from the bottom pan and drain the water from the unit.
2.Disconnect the overflow drain line and 7” diameter bypass duct.
3.While holding the bottom pan, slide the stainless steel clip off the end of the humidifier. Lower the clip end of the pan slightly and move the pan from side to side, disengaging it from the metal loops at the other end.
4.Remove the pan from the unit.
5.Slide the stainless steel retainer clip from the drum shaft support at the open end of the humidifier.
NOTE: Do not rotate the drum or damage to the motor gear train will occur.
Note
To prevent algae, it is advisable to add an algaecide to the water on a weekly basis.
