Receiving
Upon receiving the product, check the bill of lading
to ensure all items were received. Inspect each crate
for shipping damage before accepting delivery. All
damage should be noted on all the copies of the bill of
lading and a claim should be field with the carrier. 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
CUE Direct Drive
Lift unit on to the roof utilizing hooks under the
horizontal supports. Evenly space the hooks 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).

Storage
Fans are protected against damage during shipment. If
the unit cannot be installed and operated immediately,
precautions need to be taken to prevent deterioration of
the unit during storage. The user assumes responsibility
of the fan and accessories while in storage. The
manufacturer will not be responsible for damage during
storage. These suggestions are provided solely as a
convenience to the user.
Indoor
The ideal environment for the storage of fans and
accessories is indoors, above grade, in a low humidity
atmosphere which is sealed to prevent the entry of
blowing dust, rain or snow. Temperatures should be
evenly maintained between 30° to 110°F
(-1° to 43°C)
(wide temperature swings may cause condensation
and “sweating” of metal parts). All accessories must
be stored indoors in a clean, dry atmosphere. Remove
any accumulations of dirt, water, ice or snow and
wipe dry before moving to indoor storage. To avoid
“sweating” of metal parts allow cold parts to reach room
temperature. To dry parts and packages, use a portable
electric heater to get rid of any moisture buildup. Leave
coverings loose to permit air circulation and to allow for
periodic inspection.
The unit should be stored at least 3½ in.
(89 mm)
off the
floor on wooden blocks covered with moisture proof
paper or polyethylene sheathing. Aisles between parts
CUBE 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 CUE/CUBE 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 CUE/CUBE installations, the
electrical supply should be routed through the conduit
chase located between the curb cap and the bottom of
the motor compartment or through the motor cooling
tube. Wiring must conform to local and national codes.
CAUTION
Do not lift by the fan hood. Avoid lifting fans in a way
that will bend or distort fan parts. Never pass slings or
timbers through the venturi of fan. Fans with special
coatings or paints must be protected in handling to
prevent damage.
