CLEANING AND

MAINTENANCE

The Steam Humidier automatically shuts down when humidity is not needed for an extended period. After several

days of inactivity, the water tank will drain and remain empty until humidity is called again. This prevents water

from stagnating inside the tank. The Steam Humidier will rell the tank with water and reset itself when your

control calls for humidity again.

Follow these maintenance steps at the end of the heating season. Doing this each year helps keep your Steam

Humidier at peak efciency:

Clean the tank, following the procedure in “How do I clean the tank?” on pages 15 - 18. Cleaning the tank at the

end of the season ensures the Steam Humidier will be ready to perform the next time your home needs humidity.

Examine the water tank gasket. If the gasket

is cracked or split, it must be replaced before

re-attaching the water tank.

Clean out the ventilation holes in the

Steam Humidier cover.

Clear the water drain tube connected to the solenoid

valve. Disconnect the hose and inspect for blockage,

then run hot tap water through the hose.

Check that the Steam Humidier is still installed in a

level position.

• What if I go on vacation? Even though the Steam Humidier’s water tank will drain automatically after several

days, Honeywell recommends shutting off the Steam Humidier water supply and turning off the humidity

control for extended leaves. Upon return, turn on the water supply and reset the control to the desired setpoint.

What should I do at the end of the season?
