SYSTEM MONITOR AND LABEL
A properly designed system should incorporate a "System On" Indicator for affirmation of system
operation. A Magnehelic pressure gauge is recommended for this purpose. The indicator should be
mounted at least 5 feet above the slab penetration to minimize the risk of filling the gauge with water in
installations with occasional high water tables.
A System Label (P/N 15022) with instructions for
contacting the installing contractor for service and also identifying the necessity for regular radon tests
to be conducted by the building occupants, must be conspicuously placed where the occupants
frequent and can see the label.
1.7 SLAB COVERAGE
The HS Series Fan can provide coverage of well over 1000 sq. ft. per slab penetration. This will, of
course, depend on the sub-slab aggregate in any particular installation and the diagnostic results. In
general, sand and gravel are much looser aggregates than dirt and clay. Additional suction points can
be added as required. It is recommended that a small pit (2 to 10 gallons in size) be created below the
slab at each suction hole.
1.8 ELECTRICAL WIRING
The HS Series Fan plugs into a standard 120V outlet. 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. Outdoor installations require the use of a U.L. listed
watertight conduit. Ensure that all exterior electrical boxes are outdoor rated and properly caulked to
prevent water penetration into the box. A means, such as a weep hole, is recommended to drain the box.
1.8a ELECTRICAL BOX (optional)
The optional Electrical Box (p/n 20003) provides a weather tight box with switch for outdoor hardwire
connection. 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.
Outdoor installations require the use of a U.L. listed watertight conduit. Ensure that all exterior electrical
boxes are outdoor rated and properly caulked to prevent water penetration into the box. A means, such
as a weep hole, is recommended to drain the box.
