#2 Q:   Is it mandatory to mount these RadonAway units vertically, or can they be mounted horizontally in a pipe run through a limited space attic?
A:   Per RadonAway: The GP Series Fan MUST be mounted vertically plumb and level, with the outlet pointing up for proper drainage through the fan. Avoid mounting the fan in any orientation that will allow water to accumulate inside the fan housing.

#3 Q:   Is this unit rated to be installed outside under an eave but could get rained on with a side wind?
A:   Yes, all the GP fans are rated for outdoor exposure. They are typically installed on the side of the house with no rain protection.

#5 Q:   is the GP501 model comparable to the GP500 model of RadonAway. We have the 500 model and now need to replace it. would the 501 model work for us?
A:   Performance is quite similar, though the routing of the pipe will vary. All that aside, it should be a comparable unit.

#6 Q:   Can I install the fan just above the sump pit located in basement? Basement foot print is about 2000 sq ft and we have a sump which is sealed and has existing 4 radon vent that exits roof (one story house).
A:   So long as the pipe runs externally, yes. If it goes through the house it is recommended to be in the attic.

#7 Q:   I need to replace an existing unit that is mounted to the side of the house. Between the existing GP mounting bracket and the house are four rubber grommets which also need to be replaced (cracking/brittle). The installation manual mentions foam or rubber grommets can be used for vibration isolation purposes but there is no parts list so it is difficult to know if they come with the unit or not. Please let me know if the grommets come with the unit. If not, Id be interested to know specifically what you recommend. Thank you
A:   The grommets are installer provided and can be sourced locally by using a neoprene or rubber pad for vibration isolation.
