1.0 SYSTEM DESIGN CONSIDERATIONS
1.1 INTRODUCTION
The RPc, GPc, XPc and XR Series Radon Fans are intended for use by trained, professional, certied/licensed radon
mitigators. The purpose of these instructions is to provide additional guidance for the most effective use of RPc,
GPc, XPc and XR Series Radon Fans. These instructions should be considered supplemental to EPA/radon industry
standard practices, state and local building codes and regulations. In the event of a conict, those codes, practices
and regulations take precedence over these instructions.
1.2 FAN SEALING
The RPc, GPc, XPc and XR Series Radon Fans are factory sealed; no additional caulk or other materials are required
to inhibit air leakage.
1.3 ENVIRONMENTALS
The RPc, GPc, XPc and XR Series Radon Fans are designed to perform year-round in all but the harshest climates
without additional concern for temperature or weather. For installations in an area of severe cold weather,
please contact RadonAway for assistance. When not in operation, the fan should be stored in an area where
the temperature is never less than 32 degrees F or more than 100 degrees F.
1.4 ACOUSTICS
The RPc, GPc, XPc and XR Series Radon Fans, when installed properly, operate with little or no noticeable noise to
the building occupants. The velocity of the outgoing air should be considered in the overall system design. In some
cases the “rushing” sound of the outlet air may be disturbing. In these instances, the use of a RadonAway Exhaust
Mufer is recommended.
(To ensure quiet operation of inline and remote fans, each fan shall be installed using sound attenuation techniques appropriate for the installation.
For bathroom and general ventilation applications, at least 8 feet of insulated exible duct shall be installed between the exhaust or supply grille(s)
and the fan(s). RPc, GPc, XPc and XR Series Radon Fans are not suitable for kitchen range hood remote ventilation applications.)
1.5 GROUND WATER
In the event that a temporary high water table results in water at or above slab level, water may be drawn into the
riser pipes, thus blocking air ow to the RPc, GPc, XPc and XR Series Radon Fan. The lack of cooling air may result
in the fan cycling on and off as the internal temperature rises above the thermal cutoff. Should this condition arise,
it is recommended that the fan be turned off until the water recedes, allowing for return to normal operation.
1.6 SLAB COVERAGE
The RPc, GPc, XPc and XR Series Radon Fans can provide coverage up to 2000+ sq. ft. per slab penetration. This
will primarily depend on the sub-slab material in any particular installation. In general, the tighter the material, the
smaller the area covered per penetration. Appropriate selection of the RPc, GPc, XPc and XR Series Radon Fan best
suited for the sub-slab material can improve the slab coverage. The RPc, GPc, XPc and XR Series Radon Fans have
a wide range of models to choose from to cover a wide range of sub-slab materials. The RP140c and 145c are best
suited for general purpose use. The RP260c can be used where additional airow is required, and the RP265c is best
suited for large slab, high airow applications. Additional suction points can be added as required. It is recommended
that a small pit (5 to 10 gallons in size) be created below the slab at each suction hole.
