6. Install the supplied (2) 3/8 in. – 16 x 2-3/4 in. grade
8 hex bolts into the locknuts attached to the
downtube. Torque the bolts to a value of 33 ft∙lbf
(44.75 N∙m).
NOTE: The attached locknuts are not visible while the
VFD is installed on the downtube of the fan.

7. Install rear VFD cover to the back of the VFD using
(4) M4-0.7 x 10mm machine screws.
NOTE: The rear VFD cover should be installed with the
"G" on the Greenheck logo closest to the motor (not
critical for fan operation).

Safety Retention Cable Installation
IMPORTANT: Do not put excessive tension on the
safety retention cable during installation. Safety
retention cable should be taut with only a small amount
of slack in the cable to ensure proper functioning. Do
not allow safety retention cable to contact any sharp
edges.
IMPORTANT: Failure to install the safety retention cable
will result in voiding of the fan warranty.
Standard Steel Cable Clamp
The following instructions apply to
standard fan installations. For fans
that were supplied with optional

DOWNTUBE SAFETY CABLE
1. From the top of the downtube, pull the safety
retention cable until it is taut inside the downtube.
2. Wrap the loose end of the safety cable around the
mounting structure. Cable may be wrapped around
structure multiple times if length allows. Do not
allow the cable to come in contact with any sharp
edges.
3. Align the loose end of the safety cable (referred to
as the dead-end) with the length of cable that is
wrapped around the mounting structure (referred
to as the live-end).
4. Attach the dead-end of the safety cable to the live-
end using the supplied 0.188 in. u-bolt steel cable.
IMPORTANT: The first steel cable clamp must be
installed a minimum of 5-1/2 in. away from the dead-
end of the safety cable to ensure proper functioning.
IMPORTANT: Steel cable clamps are composed of two
parts: the u-bolt and the saddle. Steel cable clamps
must be installed with the u-bolt over the dead-end
of the safety retention cable and the saddle over the
live-end of the safety cable. Failure to install steel
cable clamps in this manner may result in unsafe
operating conditions. Refer to drawing below for correct
orientation.
5. Pull the dead-end of the safety cable through the
steel cable clamps to tighten the cable. The cable
should be pulled taut, leaving only a small amount
of slack in the cable to ensure proper functioning.
6. Tighten the nuts on the steel cable clamps using a
7/16 in. socket and torque to 54 in∙lbf (6.10 N∙m),
alternating between nuts until reaching proper
torque.
7. Cut or organize excess safety cable to ensure it
does not interfere with fan performance. Make
sure to leave at least 5-1/2 in. of cable between
the dead-end of the cable and the first steel cable
clamp to ensure proper functioning.
