V. ANNUAL SUMMER SHUTDOWN
For best performance, we recommend that you replace the
Humidifier Pad in your Humidifier annually.
To obtain a replacement:
• Call the installer of your humidifier.
This information is often found on your equipment.
• Call your heating and air conditioning dealer.
• Look in the Yellow Pages under Humidifying Apparatus
or Heating & Air Conditioner Contractors.
• If none of the above are successful and you still need
information, please feel free to write us or send an email to our
website.
For Models *HUMD200A, *HUMD300A close the bypass damper .

the saddle valve.
MANUAL HUMIDIFIER CONTROL:
For humidifiers controlled by a Manual Humidifier Control, simply turn the
control to the “Off” position. Shut off the water supply to the humidifier
by closing the saddle valve.
