The poster doesn't know the IP rating, and its only a foot above his head, as said if its within zone 2, and 230v, and not IPX4 < I still reckon code 4 so far.
Lets not forget, if we give this a code 2 we are by virtue saying the install is unsatisfactory. That would be a harsh call under the circumstances IMHO.
No one has disputed this truckster, the coding scenario comments are being made against xtract fans that are NOT above IPX4.
As said previously, the OP is unsure of the IP rating.
Thats why codings are being mentioned. If its IP4X your comments regarding suitabilty within a zone 1 and zone 2 environment are not in question, so indeed no codings would apply.
