Summer time use of my Aprilaire Humidifier Model 700?

Consumer question:
I recently moved into home that has Aprilaire Automatic Humidifier Model number 700. My question is during the Summer time when I switch the heat off and turn on the A/C at the thermostat. Will the Humidifier stay off or do I need to somehow turn the unit off?
Aprilaire response:
Thank you for contacting Aprilaire.

To live in Indiana, the humidifier would typically not bother to come on during summer, as nature gives us more humidity than we need. Any time the level of humidity is higher than the selected level, (or max of 45%) the humidifier will not come on.

Some people, just to make sure, will go ahead and turn down the humidistat to 'off' or at least the lowest setting. Then, for the same reasons as listed above, the humidifier will not come on.

Please let us know if you have any further questions.

    A lot of cold air is leaking from my model 700 during summer AC time. What should I do to avoid this ? Please advise. Many thanks in advnace.

    Thank you for your question.

    This question may be better answered by your heating and air conditioning contractor. The cause for air to flow out of the humidifier usually is due to a higher than normal air pressure within the air duct. This would be something that the HVAC Contractor woul have to correct.
