We have this Aprilaire Model 600 It was installed about 3 years ago and it is now leaking - we put a 2 gal pitcher under the unit and have to empty this 3 times a day - I can't afford a to have someone come out because we are on limited income and when this was installed I never received a booklet or instruction manual - I need to get one of these - hopefully this is just a minor repair - also I seen something about a filter - how often would I need to change this and would this be causing my problem?
Thank You
Theresa
