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):

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.
