I would like to put together my own duct kit (I'll put the Santa Fe in an unfinished space and draw air from the finished space).  Would you be able to tell me what type (materials of construction) of flex duct you'd recommend attaching between the unit and the wall register?  Would an insulated duct help at all with airflow noise that could possibly occur from the Santa Fe sucking air through the register?  Any input on this topic would be greatly appreciated.

8" insulated flex duct works well for reducing vibration and sound.  Suggest the duct kit for mating the 8" round to the dehumidifier.  Keep us posted on the results and further questions. Ken

The illustration on page 2 of your online Santa Fe Spec Sheet that is titled "Santa Fe Remote Duct Installation" very closely resembles what my layout will be like.  The question I have is regarding the vertical position of the return grill in this illustration (where the humid air enters).  Unfortunately, I have a wall sconce in the location of where your return grill is in your illustration (approx. 5' 6" up from the floor).  IF, instead, I were to place the return grill at the floor level (several inches off the floor), would this have an impact on the finished space circulation?  My thought is that, by having the supply and return at the same height, the circulation could short-circuit (i.e. supply air coming from underneath the door would be drawn right back into the return grill, not penetrating the majority of the finished space).

The finished area is approxiately 550 square feet.

If you foresee having the supply and return at the same level (about 3 feet from eachother) I could compromise and install the return grill 2 to 3 feet up from the floor.  I would rather not do this for aesthetic reasons, however, I will do it if you recommend it.

I have no other wall options for the return grill.  As far as changing the location of the supply air to the finished space, instead of using the opening underneath the utility space door as the supply, I could install a supply grill on the wall that separates the unfinished utility space from the finished office space (separate room), but that would allow more utility noise (gas water heater, santa fe, furnace) to travel into the office space. 

Any advice would be appreciated.

Thanks,

Dave

Humidity makes a real effort to equalize.  A supply within 3 ft. of a supply will work.  The supply of dry air will return other ways than just the undercut.  Give this a try.  Regarding ducts, I suggest 8" insulated flex.  It will absorb more sound.  The length should be +6 ft. and make a 90^ turn to be most effective at absorbing sound. Keep up posted on the results.  Thanks for bussiness and post. Ken
