Infinity Install

[runway36l]

I am having a Carrier Infinity system installed. Since the installation is the key I want to know what I can do before the installers arrive to make their job easier. I have moved what few items are in the attic to make sure they have easy access. I also had a large fluorescent light installed to provide good lighting. The electrician also ran the required 4-wire thermostat wires.

What else can I do besides staying out of their way? Thanks.
