How to Install a High Suction Blower
HS Blowers Performance Data and Curves
RadonAway HS Blower Installation
MOUNTING
Mount the HS2750 or HS5500 Blower to the wall studs, or similar structure, in the selected location with (4) 1/4” x 1 1/2” lag screws (not provided). Ensure the HS2750 or HS5500 Blower is both plumb and level.
DUCTING CONNECTIONS
Make final ducting connection to HS2750 or HS5500 Blower with flexible couplings. Ensure all connections are tight. Do not twist or torque inlet and outlet piping on HS2750 or HS5500 Blower or leaks may result. NOTE: Do NOT solvent weld fittings to unit hubs.
VENT MUFFLER INSTALLATION
Install the muffler assembly in the selected location in the outlet ducting. Solvent weld all connections. The muffler is normally installed above the roofline at the end of the vent pipe.
OPERATION CHECKS & ANNUAL SYSTEM MAINTENANCE
- Verify all connections are tight and leak-free. Ensure the HS2750 or HS5500 Blower and all ducting is secure and vibration-free.
- Verify system vacuum pressure with Magnehelic.
- Ensure vacuum pressure is within normal operating range and less than the maximum recommended as shown below:
HS2750: 5” WC (low) / 10” WC (medium) / 15” WC (high) / 20” WC (maximum)
HS5500: 20” WC (low) / 30” WC (medium) / 40” WC (high) / 50” WC (maximum)
Above are based on sea-level operation, at higher altitudes reduce above by about 4% per 1000 Feet. If these are exceeded, increase number of suction points. - Verify Radon levels by testing to applicable current industry standards and federal, state, county and local building codes and regulations.
ELECTRICAL WIRING
HS2750 or HSHS5500 Blower models come with an electrical switch box for hard wiring to a 120V electrical source. 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 UL 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.
SPEED CONTROLS
The HS2750 and HS5500 have 4-speed (low, medium, high, maximum) built-in speed controls. They are not safe for use with solid state speed controls.
