Typical Outdoor Installation
1.10 ELECTRICAL WIRING
The RP / RPc Series Fans operate on standard 120V, 60Hz AC. All wiring must be performed in accordance with
National Fire Protection (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 qualied and licensed
electrician. Outdoor installations require the use of a UL Listed watertight conduit. Ensure that all exterior electrical
boxes 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.
1.11 SPEED CONTROLS
The RP / RPc Series Fans are rated for use with electronic speed controls; however, speed controls are generally not
recommended. If used, the recommended speed control is Pass & Seymour Solid State Speed Control.
2.0 INSTALLATION
The RP / RPc Series Fans can be mounted indoors or
outdoors. (It is suggested that EPA and radon mitigation
standards recommendations be followed in choosing
the fan location.) The RP / RPc Series Fans may be
mounted directly on the system piping or fastened to a
supporting structure by means of an optional mounting
bracket.
For the ENERGY STAR Labeled RP140 / RP140c ,
the ducting from the fan to the outside of the building
has a strong effect on noise and fan energy use. Use
the shortest, straightest duct routing possible for best
performance, and avoid installing the fan with smaller
ducts than recommended. Insulation around the ducts
can reduce energy loss and inhibit mold growth. Fans
installed with existing ducts may not achieve their rated
airow.
2.1 MOUNTING
Mount the RP / RPc Series Fan vertically with outlet up. Ensure the unit is plumb and level. When mounting directly
on the system piping assure that the fan does not contact any building surface to avoid vibration noise.
2.2 MOUNTING BRACKET (optional)
The RP / RPc Series Fan may be optionally secured with the RadonAway mounting bracket (P/N 25007 or 25033 for
RP380 only). Foam or rubber grommets may also be used between the bracket and mounting surface for vibration
isolation.
