Model H-G/H-GB Centrifugal Roof Exhaust Fan
Receiving
Upon receiving the product check to make sure all items
are accounted for by referencing the bill of lading to
ensure all items were received. Inspect each crate for
shipping damage before accepting delivery. Notify the
carrier if any damage is noticed. The carrier will make
notification on the delivery receipt acknowledging any
damage to the product. All damage should be noted on
all the copies of the bill of lading which is countersigned
by the delivering carrier. A Carrier Inspection Report
should be filled out by the carrier upon arrival and
reported to the Traffic Department. If damaged upon
arrival, file a claim with 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
H-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).

When H-G/H-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 H-G/H-GB installations, the
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.
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°F 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 build up. Leave
coverings loose to permit air circulation and to allow for
periodic inspection.
H-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.
