Receiving
Upon receiving the product, check to ensure all
items are accounted for by referencing the delivery
receipt or packing list. Inspect each crate or carton
for shipping damage before accepting delivery. Alert
the carrier of any damage detected. The customer will
make notification of damage (or shortage of items)
on the delivery receipt and all copies of the bill of
lading which is countersigned by the delivering carrier.
If damaged, immediately contact your Greenheck
Representative. Any physical damage to the unit after
acceptance is not the responsibility of Greenheck Fan
Corporation.
Unpacking
Verify that all required parts and the correct quantity
of each item have been received. If any items are
missing, report shortages to your local representative
to arrange for obtaining missing parts. Sometimes it
is not possible that all items for the unit be shipped
together due to availability of transportation and truck
space. Confirmation of shipment(s) must be limited to
only items on the bill of lading.
Handling
G Direct Drive
Lift unit on to the roof utilizing hooks under the lip
of the shroud. Evenly space the hooks around the
shroud using a minimum of four lifting straps. Use
a spreader bar to ensure the straps do not come in
contact with the unit (see Figure 1).

GB Belt Drive
When lifting the unit on to the roof, use either the
four lifting points on the drive frame or the two lifting
points on the bearing plate if present (see Figure
2 for lifting points). Access to the drive frame is
accomplished by removing the screws pointed out in
Figure 3. The cover can then be removed and placed
on a flat surface in an area protected from strong
winds.
When G/GB unit is on the roof, move fan to desired
location using lifting points and fasten securely
through mounting holes in base. Shims may be
necessary depending upon roofing material thickness.
The motor amperage and voltage ratings must be
checked for compatibility to supply voltage prior to
final electrical connection. For G/GB installations, the
Hook
electrical supply should be routed through the conduit
chase located between the curb cap and the bottom
of the motor compartment. Wiring must conform to
local and national codes.
