1.0 SYSTEM DESIGN CONSIDERATIONS
1.1 INTRODUCTION
The RadonAway SF Series Radon Fans are intended for use by trained, professional Radon mitigators.
The purpose of this instruction is to provide additional guidance for the most effective use of a
RadonAway Fan. This instruction should be considered as a supplement to EPA standard practices,
state and local building codes and state regulations. In the event of a conflict, those codes, practices and
regulations take precedence over this instruction.
1.2 ENVIRONMENTALS
The SF Series 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.
1.3 ACOUSTICS
The SF Series 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 Muffler is recommended.
1.4 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 flow to the SF Series Fan. The lack of cooling air may result
in the fan cycling on and off as the internal temperature rises above the thermal cutoff and falls upon
shutoff. Should this condition arise, it is recommended that the fan be turned off until the water recedes
allowing for return to normal operation.
1.5 SLAB COVERAGE
The SF Series Fan 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 a Fan best suited for the sub-slab
material can improve the slab coverage. The SF180 is best suited for general purpose use. 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.

IN065 Rev C Page 4 of 8
1.6 CONDENSATION & DRAINAGE
Condensation is formed in the piping of a mitigation system when the air in the piping is chilled below
its dew point. This can occur at points where the system piping goes through unheated space such as an
attic, garage or outside. The SF Fan has an integral means for water to drain back to the slab hole to
remove the condensation. The SF 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. The SF Series Fans are NOT suitable for
underground burial.
For SF Series Fan piping, the following table provides the minimum recommended pipe diameter and
inlet pitch under several system conditions.
Pipe
Dia. Minimum Rise per Ft of Run*
@25 CFM @50 CFM @100 CFM
4" 1/8 1/4 3/8
3" 1/4 3/8 1 1/2
*Typical SF160 Series Fan operational flow rate is 30 - 90 CFM 0n 3” and 4” pipe.
(For more precision, determine flow rate by measuring Static Pressure, in WC, and
correlate pressure to flow in the performance chart in the addendum.)
On an outdoor installation a condensate bypass is not required. The SF Fan contains an
integral internal bypass suitable for use in cold climate installations which require long lengths
of outlet ducting or where the outlet ducting is likely to produce large amounts of
condensation because of high soil moisture or outlet duct material. Schedule 20 piping and
other thin-walled plastic ducting and Aluminum downspout will normally produce much
more condensation than Schedule 40 piping which is prefered.
1.7 "SYSTEM ON" INDICATOR
A properly designed system should incorporate a "System On" Indicator for affirmation of
system operation. A manometer, such as a U-Tube, or a vacuum alarm is recommended for
this purpose.
1.8 ELECTRICAL WIRING
The SF Series Fans operate on standard 120V 60 Hz. AC. All wiring must be performed in
accordance with the National Fire Protection Association’s (NFPA)”National Electrical Code,
Standard #70”-current edition for all commercial and industrial work, and state and local
building codes. All wiring must be performed by a qualified and licensed electrician. Ensure that
all exterior electrical boxes and other components are outdoor rated and properly sealed to
prevent water penetration into the box. A means, such as a weep hole, is recommended to drain
the box. Note that the exterior electrical box may be mounted under the removeable bottom right
corner cover. If located under the corner cover the electrical box should be positioned relative to
the inlet pipe using the template provided.
1.9 SPEED CONTROLS
The SF Series Fans are rated for use with electronic speed controls. The recommended speed
control if used is Pass & Seymour Solid State Speed Control Cat. No. 94601-I.

2.0 INSTALLATION
The SF Series Fan can be mounted indoors or outdoors. (It is suggested that EPA
recommendations be followed in choosing the fan location.) The SF Series Fan is intended be
mounted directly on the system piping. There is no mounting bracket available for this unit. In
addition to the inlet and outlet pipe mounts a single vibration mount is provided at the bottom
right hand corner of the inner housing, underneath the removeable corner cover, the vibration
mount may be screwed directly to the house siding.

2.1 MOUNTING
Mount the SF Series Fan vertically with outlet up. Insure the unit is plumb and level. When
mounting directly on the system piping assure that the fan body does not contact any building
surface to avoid vibration noise.
2.2 SYSTEM PIPING
Complete piping run, using flexible couplings as means of disconnect for servicing the unit and
vibration isolation. If 3” inlet piping is used mount the eccentric adapter supplied inside the 4”
flexible coupling, connected to the inlet, with the “TOP” arrow at the high point pointing
towards outlet.
2.3 ELECTRICAL CONNECTION
Connect wiring with wire nuts provided, observing proper connections (See Section 1.8):
Fan Wire Connection
Green Ground
Black AC Hot
White AC Common
2.4 VENT MUFFLER (optional)
Install the muffler assembly in the selected location in the outlet ducting. Solvent weld all
connections. The muffler is normally installed at the end of the vent pipe.
2.5 OPERATION CHECKS
_____ Verify all connections are tight and leak-free.
_____ Insure the SF Series Fan and all ducting is secure and vibration-free.
_____ Verify system vacuum pressure with manometer. Insure vacuum pressure is less than
maximum recommended operating pressure
(Based on sea-level operation, at higher altitudes reduce by about 4% per 1000 Feet.)
(Further reduce Maximum Operating Pressure by 10% for High Temperature environments)
See Product Specifications. If this is exceeded, increase the number of suction points.
_____ Verify Radon levels by testing to EPA protocol.
