1.0 SYSTEM DESIGN CONSIDERATIONS
1.1 INTRODUCTION
The RN104 radon fan is 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 RN104. 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 RN104 radon fan is factory sealed; no additional caulk or other materials are required to inhibit air leakage.
1.3 ENVIRONMENTALS
The RN104 radon fan is 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 RN104 radon fan, when installed properly, operates 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). The RN104 is 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 RN104. 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 RN104 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. 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.
