[pianotech] Disklavier DC installation

Greetings list, 

I was wondering what kind of results folks have had installing a DC system in a Disklavier. Here's my situation: 

The GH-1 is located in a high rise apartment building (28th floor, the view is great!). The owners have the entire floor--the room the piano is in is huge--so a room humidifier isn't going to be effective. The windows--all around the building are floor to ceiling--it's always warm in there no matter what the season and in spite of the fancy blinds. 

I called Yamaha and was told the humidifier bucket should not be mounted under anything electronic. I contacted Dampp-Chaser and asked if the humidifier would be effective in the only spot it would fit--on the straight side. The response was that the effectiveness would be reduced, but they didn't know by how much. 

There are options-- 
1. just have the piano tuned more often. 
2. Install the dehumidifiers & humidistat only to head off the higher humidity times. 
3. Install the whole system and pray that it works after the customer has paid the big bucks for it. 

Has anyone installed a complete system on a GH-1 Disklavier and did you get good results? I forgot to ask at Yamaha if an undercover would be OK, since the electronics makes some heat. 

Thanks,
