2.6 OPERATION CHECKS & ANNUAL SYSTEM MAINTENANCE
______ Verify all connections are tight and leak-free.
______ Ensure the SF180 Fan and all ducting are secure and vibration-free.
______ Verify system vacuum pressure with manometer. Ensure vacuum pressure is within normal
operating range and less than the 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 Specications. If this is exceeded, increase the number of suction points.
______ Verify Radon levels by testing to EPA Protocol and applicable testing standards.
2.0 INSTALLATION
The SF180 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 SF180 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 exible 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” exible coupling, connected to
the inlet, with the “TOP” arrow at the high point pointing towards outlet.
2.4 ELECTRICAL CONNECTION
Connect wiring with wire nuts provided, observing proper connections (See
Section 1.10). Note that the fan is not intended for connection to rigid
metal conduit.

Black AC Hot
White AC Common
2.4 VENT MUFFLER (optional)
Install the mufer assembly in the selected location in the outlet ducting.
Solvent weld all connections. The mufer is normally installed at the end of
the vent pipe.
