Annual maintenance for keeping your Aprilaire Humidifier running at peak performance

Friday, October 7, 2011 by Aprilaire Team
For best performance, we recommend that you replace the Water
Panel evaporator in your Aprilaire humidifier at least annually with
the exception of Models 400 and 400M which should be changed at
least twice per heating season.

The “Change Water Panel” indicator light (Digital Control only) will blink
when it is time to change yourWater Panel. See individual model instructions
for additional maintenance.

To purchase a new Water Panel:

• Visit estore.aprilaire.com
• Call the installer of your Aprilaire humidifier.
This information is often found on your equipment.
• Call your heating and air conditioning dealer.
• Use our “Dealer Locator” at: www.aprilaire.com
• Purchase only Genuine Aprilaire Water Panels to maintain performance.

If your humidifier is equipped with a Digital Humidifier Control with Water
Panel change indicator, after replacing the Water Panel, turn the control
knob to the “Test/Reset” position until the “Humidifier On” light blinks to
reset its timer. (Blower must be operating and HVAC calling for heat.) Be sure
to turn the control knob back to it’s original setting. If the “Humidifier On”
light continues to blink, your humidifier is in Test mode. DO NOT LEAVE THE
CONTROL IN TEST MODE OR HUMIDIFIER WILL NOT OPERATE.

Also review the periodic preventavtive maintenance in the owners manual.

I have an 800 humidifier and it work well but I hear a high pitched sound occasionally when the unit is running. It is annoying; is there anything that can be done to stop the sound.
