New standard control pack

I just purchased a standard control pack from HotTubWorks and on page 16 of the manual, in all capital letters, it says "CAUTION: THE EQUIPMENT AND CONTROLS SHALL BE LOCATED NOT LESS THAN 1M (5 FT) HORIZONTALLY FROM THE SPA OR HOT TUB." it also has a sticker on it that says the same. This unit is meant to be installed under the skirt of the hot tub just as it is shown in the pictures on the web site. So I am in violation if I install the control pack in the same location as the original? This sounds like a "cover your ass" statement and any use of this product is at your own risk. If they are refering to the GFCI box, then the statement is very poorly worded.
