I don't believe it should be watered on a schedule. Lighting and temperatures can vary based on the time of year, so your plant will dry out at different intervals.
I believe an East window is best for these, but I've read people successfully growing them in North windows. Avoid West and South, as they both have afternoon sun and will burn it.
I'll leave when to water to someone else, I still haven't mastered it myself.
I don't know the opinion of folks on ATP with regards to what kind of water to use. Some believe that chloramine is detrimental to the health of an AV and so is chlorine, either of which may be found in your tap water (more likely chlorine, but some cities have started using chloramine). My Mother uses bottled water to avoid adding anything fround from tap water. No hard or soft water either.
Fertilizing weakly, weekly is best. 1/4 strength a week is best. Avoid AV fertilizers with chlorine added to them.
I hope this gets you started.
